FYI, filmic is now part of Blender 2.79! No need to download anything extra :)
So, maybe a quick guide on how to set it up and use it would be useful? :)
Yomo agreed!
I thought the creator of filmic blender said that there are some issues with the internal implementation of filmic. I would recommmend downloading it just in case.
No reason to switch back. The version in 2.9 by default is fine.
So...how do I know if the version packaged with blender is turned on? Maybe I'm blind but my renders look the same...
His actual dining room looks fake
yeah i was like that shity render :D but no its just iphone crapy camera :D
That's what I was going to write haha, the true picture looks fake
Tetrachromia I though the photo was a render. :)
That's because it is.
hhhhhhhh i thought its a render Daaaymn!
Andrew's real dining room actually looks like a render, too. I think he is literally living inside of Blender at this point and he doesn't even realize it.
I was gonna say, that room looks like a great but underdetailed room.
It's the camera's dynamic range.
Just came to the comments to find this particular one, thank you.
God made the world with blender. You see the default cube? That's adam himself.
We were all defaut cubes at the start
I downloaded the link and started the process to download until i realized that blender 2.82a is already using filmic color management. Realized that this video is uploaded in 2017. Your campaign was a success congrats :)
Yeah here I am with 2.92 thinking, damn, I need this. Then i realized it's there by default.

Yup, Blender version 2.79 added it as Blender Guru mentions in his pinned comment.
The fact that it improved a default cube concerns me.
still very deletable
This issue has been fixed.
Default cube shall rise
things i took most from this video:
Dude's dining room is so sleek it looks like it's CG
You know he cleaned it rigorously for this video.
His real dinning room doesn't have enough "clipping" apparently.
proffesional defformation xD
Legit, if he had showed that photo first I would've been like, "oh great, can't wait to see how he makes this look real"
It's a nice dining room tho
I feel so betrayed by the Blender Devs for making me use sRGB this whole time even though I've literally never used Blender in my life
I'm right with you. lol
Hell yeah, and thanks to us this became standard option of the Blender.
@@11kele exactly, we did it together
Yep.................me too!
Haha...

This guy's rendered Curtains look more realistic than the real one lol 😂.
As a photographer the sentence "something so seeming unimportant as dynamic range" made me laugh way harder than it should have
Me too
Inside cg world there are no limits at dynamic range , and only challenge is to imitate it, dynamic range important for cameras , inside software you can do whatever you want
Lol me too, I was like "HOW DARE YOU!!" 😂
*takes one picture of a waterfall*
Yuh really shows that there is a very odd disconnect between photographers and renders
This 30 minute video of light dynamics in a software I have never used is apparently more important to my brain then studying for exams.

Even though Filmic is now part of Blender, this video still taught me a lot about color and adjusting color in Blender in Nodes. I found all of it to be very interesting and useful knowledge. Thank you, as always!
Reference photo is clearly a render. Blunder Guru is an advanced generative AI of some sort.
My heart stopped at "free"...how could something so significant be free? I'm blown away by the blender community
Good products don't have to be paid for, but if I had put hundreds of hours into something I would consider charging people for it or at least accept donations.
It is likely (it seems to me, at least) that having Arnold spreadding to the other softwares, the knowledge is running horizontally over the professionals (be it, no secrets on the methods and formulas... almost all publicly available). Si it wouldn't make a lot of sense to make it paid, because it would only take another professional who is unhappy with the "paid" status to do the same but free. Either that, or out of pure kindness... blender comunity is pretty kind
So I was just trying to say how nice the community is...now everyone is philosophying about money and the reality of it...geez way to overthink it :D
Most likely answer? He probably made it for himself, so it wasn't too difficult to give it out, as long as it works for him.
i tend to believe that mods fo an open source program should be free with an optional donation. just like the program itself. but thats just me
As a game developer, I have written a game engine that renders scenes in HDR, which potentially produces very intense lighting values. I use tone mapping to convert the 0-x light values down to 0-1 RGB values that can actually be displayed without clipping. The tone mapping operator even includes a bit of math to produce the realistic desaturation effect you mentioned. I also experienced the same issue with intense lights changing hue: this happens because clipping can alter the ratio between the R, G and B channels. I appreciated this video because it was like a mirror image of everything I learned in the course of making my game's lighting display correctly, only seen from another perspective. And the final result speaks for itself- educating people on this topic is a good thing.
game devs always impress me so much
What game are you creating?
@@mirogaming4389 you are like the trolling NPCs in games, sees player with good alchemy skills and guard says "an alchemist eh? can you brew me an ale?"

I'm also about to write one in the future so just watched this to see if I learn something.
This is even better than gamma correction.
We never should've jumped to 4k, we should've jumped to HDR at 1440p
Want to really get pissed of. That's just a nice, 2000s CRT. We had high resolution, refresh rate, and excellent dynamic range... but sacrificed all of that for smaller footprint and lower weight. Only now with OLED are we catching back up to the same quality. We've been in a 20 year video dark age.

@@masterjohn3126 imagine saying 'facepalm' in 2019 unironically, I clicked on a video in my recommended tab because I was curious about how it worked.
One of my favorite things about watching your videos is that almost every time you complain about something in an old tutorial, I don’t end up having the same problem in the most recent version of blender. The fact that these things get updated and polished constantly gives me a lot of trust for blender’s future and as a 3d noob it’s very comforting.
I don’t do any 3D modelling but I really like this guy’s voice
I never had Blender installed in my computer, and honestly I won't be doing any 3d stuff any time soon... yet here I am, watching all your videos.
I seldom do any active rendering but Andrew's just so damn friendly and enthusiastic I can't help but watch his videos.
Sounds like rape.
why?
Because he's being forced to do something because someone else is "just so damn friendly".
Who doesn't love explaining a joke first thing in the morning..

I did film production and photography in college and NEVER once heard the term “Middle Grey”, thank you for that! I feel like that’s going to offer me an opportunity to improve my photography and filming!
They should go and adjust their exposure 1.01 class then!
6:00 lmao I thought you were trying to fool my ass and then just say like "oh no that's actually a render with fixed lighting". Really looked like a render
Your room has nice graphics

With cycles of course
Also, the actual photo of the dining room looks fake to me for some reason... :D
I swear I can see individual polygons the kitty is made of. I guess I am getting crazy. :D
thegoodhen I legit thought the exact same thing when I saw the photo, I thought it was the final render
Also, CRT monitors are great, still have one by my side as I'm typing this comment! :3
Pheew, so I'm not the only one. I had to pause the video there and get closer look, and I still thought it was render :D
it's look fake to you because you are a chicken ! Your are a fake bird !!
As soon as you called your explanation "Dynamic Range", HDR just made a whole lot more sense.

Coming from a photography background myself, I did think about most if not all of these aspects, but making that connection so systematically and showing HOW to implement proper amounts of dynamic range etc. is just very fulfilling to watch, and gets me really excited on diving into my current project's VFX side. :)
I think it's awesome that Blender took it upon themselves to integrate this into their update.

Thank you for making tutorials! I watched a few to get familiar with Blender. It was easy to follow and the way you lay out hotkeys and sometimes even explain what the program is thinking was really helpful.
How the F*** are your videos so informative...
hehe thanks mate
He lives up to the name Blender Guru :)
Nash Jordeen +1 for this comment's appropriate intensity. and now we know it won't clip.
Tone of voice is hard to discern via text
This sounds aggressive
Dynamic range isn't measured in "f-stops", it's just measured in "stops". A f-stop is a measurement of the aperture of a lens.
Yeah that bit confuses me. Since my lenses go up to 30 f-stops.
Technically not true that high end lenses only show t-stops. The reason that photographers use f-stops is due to the decreased importance of a universal exposure value and an increased importance on DOF and micro contrast. Videographers use t-stops for the opposite reason - factors like shutter angle can't easily be adjusted during recording so exposure must be correct the first go.
Actually, it's even more simple than this. F-stop is a theoretical mathematical value. This is why it's used in things when discussing dynamic range. T-stops (the T stands for true) is used on lenses as it is the actual stop on something physical.
Cut 'im some slack, he's a modeling nerd, not a camera nerd.
T-Stop is way more expensive because it has to be very accurate F-Stop is theoretical value so for filming you don't want your exposure to change even a bit when changing your lenses or zooming in etc for photography its not as a big deal and we get cheaper lenses.
I'm gonna be honest, I normally don't stick through tutorials this long. But the information and the way you explained it was EXTREMELY helpful and gave me such a better understanding of the way blender is managing my colors. I do a ton of product renders and this has helped me more than you could know! Thank you!
6 years later and this video is still helpful. thanks for putting all this info together!

yeah its fun! :D
Same here :O
what is blender? I'm joking ... i just googled it
Also maybe im missing the point but your dining room looks like a render irl
Minimalist interior perhaps? Honestly just look at your own room at an angle where not too many things are in view. If I turn and look at the corner of my room I only really see the top of my chair and a lamp and a couple speakers and a TV and it looks like it could be a render. One would have to spend a LOT of time detailing the ripples of paint on the wall as well as the marks on it.
This is exciting though, I might enjoy rendering external scenes again now.

Does this ever happen to you? I don't do any rendering, I'm not a photographer, I have no idea why this was in my recommended. I still watched the whole thing.
Knowledge is power
Do you watch gaming vids or gaming docs?
Nice overview here!! At Pixar (I was a shading TD) they render in 32 bit and tone mapping is done later. Their tools can create accurate bounced light, but everything is lit 'artistically' so each shot may have 20-30 lights in it. Characters have their own lights too. The thing that I thought was kind of crazy was that every shot gets broken out into it's own file, so the lighting has to be done for each shot separately. You cannot go in and edit the lighting for an entire sequence or set, after a certain stage of production.
With renderman, true Ray tracing was not even a standard feature until recently. Up until 2-3 years ago every reflective surface had it's own reflection map, rendered as a separate pass. Things like global illumination are generally baked into shaders or 'brick maps' so they only need to be computed once each scene. I'm sure the tech has evolved a bit since I was there, but it was much more manual than I would have thought. Still, the quality of the renders at full resolution is amazing.
tell me more, tell me more, did you get very far ?
from what i understand, in non-animated movies, the lighting is also adjusted for each camera angle, so they are essentially just mimicking the normal way of shooting a film. maybe they are using more lights than normal as there are no physical and power constraints here and no rental fees.
@AaronDavis Pixar transitioned largely on Monsters U to a global-illuminated lighting model (radiosity). Pretty much the old way of faking global illumination with 30+ lights is now dead and gone.
Tell us more, we thrive off this!!!
This was very intuitive. Well explained, easy to understand and implement. Great job, and kudos to Filmic Blender Developer of course!
This was a very helpful tutorial. Short and to the point but still had the content it needed.
18:34 I know this video is two years old, but the phrase is “paradigm shift,” not “paradox shift.”
context
@@shondelb5175 what
I know your comment is one year old, but I'm hungry.
For those wondering where the effect of colors fading out to white from overexposure/lightintensity comes from:
The sensors in your eyes that detect different colors don't actually 'just' detect red, green or blue light. As a matter of fact, the color 'red' is not just a single wavelength of radiation but more a spectrum that we've classified as being 'red'.
They're not completely immune to other colors. So when we are talking super-exposure you get to a point where if there is an enormous amount of light in the red wavelength spectrum hitting your retina and all of your red sensors are blaring at your brain, you reach the threshold of your blue and green sensors starting to fire making your brain think it is also seeing those light-types and thus your brain 'washes' the red color out increasingly to pure white as the exposure becomes more and more (because red + blue + green = white according to your brain).
Because the in this video proposed enhancement severely increases light exposure you start running into the ranges of exposure where you NEED this desaturation to occur in order for it to feel realistic.
The most important thing to take away from all of this is that 'realism' in the field of photo/video editing/rendering has nothing to do with physical reality but with how WE, the 'viewer' see said reality. Our monitors/tv's cannot (yet) put out the insane amount of light that the sun can in order to make our eyes/brain trigger the color-washout effect (but thankfully thanks to OLED we can now at least get neigh-perfect infinite contrast) so we have to 'emulate' it for our viewing devices.
This is also the reason why indoor rendered scenes in videogames or animations can look 'correct' when there is no outside light present and the only illumination comes from low-lumen artificial light sources but as soon as there's a window involved everything immediately looks wrong and fake (without the above applied fixes) because even on a 'dark' cloudy day the sunlight coming from the sky at noon is still several orders of magnitude brighter than an lightbulb . This is a problem that I, as a gamer, have often witnessed in videogames in the past and even up to this day.
Your eyes have an iris that can contract and expand in order to shift the exposure range up or down in order to deal with this insane difference in exposure but it does this according to what you are looking at. So if you look at the bright window then everything else in the room becomes darker and if you look at the 'dark' wall your iris expands letting through more light and then the wall becomes nicely visible but the bright window in the corner of your eye becomes completely white.
This is another issue with 'static' rendered images because basically you have to 'decide' for the viewer what his eyes should focus on and that takes away the realism as well. Because on a static image you can look at the dark bookshelf in the corner of the room or the over-exposed table and the exposure doesn't change but in reality your eyes would adjust to their brightness accordingly.
So, even though with the tricks used in this video you can simulate 'photo'realism, you still won't be able to simulate ACTUAL realism in the way you are capable of in an interactive experience such as a videogame where you can simply adjust the exposure based on what the crosshair is pointing at.
One reason I never enjoyed DoF is because I ignore center screen 75% if the time. Now that we're getting VR and eye tracking.. Wooboi.

23:35
Yellow, Cyan and Magenta
oh cmon, that's basic.
Yolo, Cyna and Magneta!
Yea, but those are RGB yellow, cyan and magenta, so whatever, aqua it can be! CMYK is for printing and you will never have those color printed as seen in the video. Not close at least, specially the cyan. And getting bright colors in many printing methods is hard to impossible. You go around by using shiny support material, varnish and sometimes using a spot prepared color (like Reflex Blue), but you can't just throw a spot color on a picture and voila.
Anyway, I will stop here! :) Have a good day, sir!
hdmi is encoded in cmyk...
@Mike Crapse What the fuck? Were you drunk when you typed that? CMYK is for printing. Simulating CMYK is just simulating. RGB and CMYK are color models, like YCbCr (which can be used by HDMI).
People like troy is what makes Blender such a great tool

Have you tried to re-render your sci-fi drone with Filmic?
he wouldn't notice any difference since he said that he "tweaked" it with photoshop so..
No, i think he said that before he got to know Filmic.
Anyway i was just curious to see the comparison.
Ultimately i think people could just download/do older tutorials of his using this tweak and see how it goes.
you don't need to rerender stuff ehh video is full of mistake. it is just. setting how u read data.
THANK YOU! You are 100% right, this isn't some revolutionary way to "correctly" work with colour. The correct, physically accurate, most life like way to work with colour is with a simple linear workflow. Which is the default in blender... Just render your shit as linear 16 or 32 bit exrs, and colour correct to your hearts content, with no loss of information. This video is riddled with misinformation.

Filmic Blender is on the official target list for Blender 2.79 for quite a while now.
No need to start a big campaign for inclusion in master as suggested in 10:40 , the developers are on it :)
Until then, enjoy Filmic Blender as an addon.
Thanks to this video, and to the page on facebook who published the video, I knew about this, not thanks to the "developers". So...

So when is 2.79 out? Do you recommend we wait?
Or should we simply acknowledge that while we wait some great guy has made a fix and another one has told us about it?
wiki.blender.org/index.php/Dev:2.7#Suggested_targets
looks like early May, but no need to wait. Just follow instructions in the video.
My comment was probably misleading. I didn't suggest to wait. There is just no need to push the devs as suggestest in 10:40, they are on it :)
Ah thats great to hear!
I haven’t even installed Blender. This is literally the second tutorial I’ve watched and I feel like I’ve been given a several month head start on my skills. Thanks!
!!!!!! I'm so glad youtube recommended this! I still don't understand a lot of the numbers and the specifics of how color works, but I will definitely use this. also I had no idea about the "false colors" thing! that is super useful
also nice that it is a part of blender so I don't have to mess with any files or download anything
i have 0 experience with photo and visual technical stuff but i do have lots of experience with the technical side of audio, and this was very easy to understand (probably also because you explain it really well)
lots of parallels between this and how an audio signal works, with terms like dynamic range and clipping. super interesting. when mastering a render of a song, you need something called "headroom" so that you can get the signal loud enough (using tools like compression as necessary to make the quietest parts louder) without making the loudest parts of the audio clip at all.

Apropos people who misunderstand colour spaces... for one sRGB being ancient is neither here nor there, because all web images and webbrowsers are sRGB, and all displays are approximately sRGB when displaying 8-bit inputs, as is the output of the iPhone camera in JPG mode (or high-depth linear in RAW mode). Most commercial LCD PC monitors and TVs don't even cover the complete sRGB space, neither on gamut (unless they use RGB backlighting) nor on dynamic range, so all they have to work with is a rather pitiful approximation. For all the faults of CRTs (geometry, resolution, sharpness, convergence), colour reproduction was not generally one of them, and they are still occasionally used as colour reference.
For other, that sRGB represents only 8 f-stops is a blatant lie and misunderstanding. It would be if it was 8-bit linear space, but it's an 8-bit exponential space, with an approximate exponent of 1/2.2. So how much dynamic range does it have? Let's say we take the point of the lightest non-zero value, it has a linear value of (1/255)^2.2=0.000015, or close to dark resolution of 16-bit linear. Now that is of course not quite correct, because sRGB has a linear section at the start, while i have used substitution approximate gamma, so it's realistically closer to resolution of 12-bit linear, or 12 photographic f-stops, if resolution loss at brightest tones is partially neglected, which it can be according to perceptive metrics.
When rendering, generally infinite dynamic range is assumed, because any exponent of 0 is 0, in Blender and elsewhere. However this is not how cameras work. Specifically because their dynamic range is finite, they end up mapping the values to maximize useful information and reject noise, and this is what is missing and has been correctly added by Filmic Blender, and the explanation written by its author Troy Sobotka is absolutely correct. You merely failed at reading it.
So, Filmic Plugin actually makes it look more like a photo (by reducing information in the same manner as a camera) rather than more realistic, per se?
You could say so, James, except we neither necessarily have a "ground truth" for realism that doesn't stem from a camera, something we could faithfully compare against, nor do we have display devices that are capable of representing a real light field.
Shalok Shalom I don't have an opinion on Mirasol displays specifically, but I'm sceptical about the dynamic range of any reflective media. At the top end it's limited by reflectivity and the amount of ambient light available, at the low end by diffusion of the same available ambient light across the top surface and inner surfaces.
Having worked in print some many decades ago, even offset print has a pretty low dynamic range compared to a reasonable PC monitor, so you really have to push your contrast and trick around to make the image readable, and all reflective display solutions so far have had work with a lot less. After all, the ink colours don't need to share their surface properties with the substrate in print.
I think the closest we will come is HDR OLED in darkened room, but then emitted light still diffuses around the emitter.
Shalok Shalom you'll still be judging it in comparison to the brightly lit environment, and with the losses we have in glass electrodes alone, you get a choice between somewhat dim display and low viewing angle. Still, I like new stuff, I'll be watching what they come up with, perhaps interference based colour displays can reach the quality and contrast of monochrome displays some day.
In old news, I think CCSTN displays were curious. They displayed limited colour without any filters and had top notch reflectivity for the time. Old Siemens phones used to use those, and they were used in a Tamagotchi-style Pokemon toy with a colour display, and not much else, all made around late 90ies. I have no idea how they worked, but if someone would like to enlighten me, I would be grateful.
Augustinus, let's try this, shall we? 0^2 = 0*0 = 0. Ergo, not every exponent of 0 is 1. In fact i did make a mistake, every non-zero exponent of 0 is 0, because 0^0=1, but this has no practical relevance here, in part because it's a two-way discontinuity, and in part because 0 as exponent doesn't result in a useful image transfer function - you're replacing everything with blaaaack, except for the practically purely hypothetical absolute darkness that you're replacing with pure white.
Amazed. Once again. When will you ever drop in quality? There must be a ceiling?!
But no, yet again: Another gamechanger from Sir Andrew...
This is the kind of thing i would hate being taught at school but look at me watching this video and being so thankful to now know all of this. I guess it has to do with the concrete examples and the awesome teacher ! Thank you so so much !
This video was a starting point but as I come to understand aces after all these years I can appreciate how easily you explained that hard subject to not so experienced uses kudos to you
This tutorial is so well-done. It explains everything in the perfect amount of detail and gives very easy-to-follow instructions. Amazing!
I wish you would have showed the 100 strength value for the sun in sRGB for comparison
Im learning some new things every day. Thank you youtube algorithm
I've never even touched render or thought about making digital art yet I watched the whole thing. Great video
6:00 The reference also has a cat, which immediately makes it inherently superior to any cat-less render.
In case anyone is confused by the difference between "display referred" and "scene referred" data, it has to do with a logarithmic vs linear representation of light.
Our eyes perceive light _logarithmically_ , meaning that the difference between 1 and 2 looks the same as the difference between 100 and 200, so it makes sense for monitors to use logarithmic values in order to have the same _perceived_ level of detail in the darkness as in the light.
The problem is that fundamentally, light is just a collection of photons, and in order to properly add them together, you need to do it _linearly_ . When you add 10 + 10, you want to get 20, not 100. This is why logarithmic light values have problems with clipping when you add them together (the further you get from the "center" of the log-scale, the more extreme the difference becomes), and why you should stick with the linear values until the very end.
I'm not a blender user or even a render-er in any way but watching this changed my life, thank you Guru, and thank you Troy
2:00 it's interesting because I have to focus on the 2nd square from the left or the black shade blends in with the most black to the far left. I'm glad technology allows us to experience dynamics like this.
This is all well and good (filmic blender), but there are a lot of misconceptions and misinformation in this video. All renderers (including Cycles) render under the hood in a linear colourspace. This is so that the math behind everything is correct and not skewed. Its necessary for a correct representation of physics and energy transfer/propgation/light simulation, which is what path tracer renderers like cycles do. Thus, by default, Blender actually outputs a linear image, because it renders a linear image. The sRGB conversion (display device) is done so that it looks correct on your monitor... It isn't some old, terrible workflow, its literally so that the linear image that is rendered to work like real life, looks like linear and natural to you when you look at it on your screen. It takes a while to understand, but Blenders own color management wiki page does a good job of explaining it.
The point is, this filmic blender plugin doesn't actually "fix" anything. Nothing was broken. Blender and any other renderer that can render in 16 or 32 bit floating point has near infinite dynamic range, not 8 or 25 as you say.
This is merely a plugin which emulates the nice logarithmic effect that film has. This is a method of tone mapping, or shifting all that colour information, the bright whites and dark blacks, into a space that looks natural to your eye, and can fit in an 8bit image or video that can be viewed on the vast majority of consumer devices that can only display that much information.
I am now interested, can Blender output in any HDR formats compatible with compliant devices (HDR10/Dolby Vision), is there any configurations or plugins for this?
If Blender has a practically infinite dynamic range why does it not give the same results as the reference image? How can you change the dynamic range to mimic a DLSR or human eye?
I've been shooting LOG footage on cinema cameras forever, and it's really cool being able to get essentially LOG footage and colorgrade it how I'm used to with real cameras in blender. Your tutorials are AMAZING!
Needs a short update video. Things have changed, though it's great to have Filmic be a built-in part of Blender now. It's not labelled "Render View" any more, but "View Transform". Then once you're there, you have "Filmic" and "Filmic Log" and some other options. Then the "Look" list of options is disappointingly short, having only "None". Please guide us through these uncharted lands, oh good Guru of ours!
I'm a color management expert and I had no idea this knowledge would apply to blender so much
5:55 oh he fixed the light cool... wait this is real photo
