Great tutorial. Very clear explanation. With real cameras, depth of field effects are also influenced by the focal length of the lens and the sensor size. Longer focal lengths give larger and more pleasing bokeh but can make the focused subject appear flatter. Larger sensor sizes enhance the narrowness of the depth of field, so ƒ/4.0 on a 135 sensor appears much larger than the same ƒ-stop on a bigger 120 sensor. I don’t know if Blender properly simulates this but it’s worth trying out, as I noticed those settings are available in the Properties panel. The wider the aperture the more chromatic aberration you’re likely to encounter at the edge of the frame, so if you want to make your wide-open renders look true to life try simulating this. Also, for the non-photographers out there, ƒ/1.2 is common for fast high-end lenses. ƒ/1.0 and ƒ/0.9 lenses were available on some compact film cameras (you can find plenty of examples on Flickr). The fastest lens I’ve heard of was ƒ/0.7, used by Stanley Kubrick to film candle-lit scenes in Barry Lyndon with no additional lights. Finally, most standard ƒ-stops differ by thirds of a stop but some older lenses differ by half-stop increments.
I have been looking for these camera settings explained and this is EXACTLY what I needed. I would welcome more in depth explanations of camera settings. You obviously know what you're talking about. Many thanks!
Thanks for the detailed explanation and answering my question below (that it does not work on Blender internal renderer) I've never had much luck or understanding of the Cycles engine, but the results are clearly better. Thanks again and thumbs up.
Love this description of the tools for DoF in blender. You made it easy to understand now. The only thing I feel needs correcting is your depth of field terminology. When you have more depth of field, more of the image is in focus. When you have less depth of field, less of the image is in focus. That was reversed in the video. As a photographer, that kept confusing me and may confuse others.
+Matt McKee thanks! And you're absolutely right. More blur = shallower depth of field. I like to think/ refer to it as more "depth of field effect" for beginners or kids usually, that's where my mistake came from.
Yes Matt Mckee, and I noticed something else. The aperture tool refers both times to the wideness of opening, even when there's no 50cm objective. But keep up your fabulous vids, Love them to!
1. THANK YOU SO MUCH! Exactly what I was looking for! 2. You sound a lot like the guy who voiced Donatello in the 2004 animated Teenage Mutant Ninja Turtles series and voiced Spider-Man in the recent Amazing Spider-Man video games. But that's not a bad thing. Keep up the good work!
This is what I'm looking for in my current render. But my question is, is the depth of field function still buggy even in the stable release in 2.74? I'm still starting out in 3D modelling and your tutorial really helps a lot! Keep up the good work!
Are you ever going to do a tutorial about sculpting, I'm trying to make a character for my game but when I use regular modelling he ends up looking blocky.
***** Not in the very near future, but it's on the list. I just need to think of a good abstract object to teach with. A Pillow is the obvious choice, but it too commonly used. Any thoughts?
Great video! I was hoping I could use this effect to pan down a document and have the words blur into and out of focus as they come to the center of the frame, but this looks like the wrong technique for that. But it is certainly useful for many other things.
Does this beautiful technic works on bigger objects? I would like to use it on models that are in a cool position and such and use the blur so can add drama or similar. Is it possible?
In the Cycles render engine? Blender 2.7x? --> Select your camera, and in the Properties window > Camera Tab > section: Depth of Field .. de-specify a focus object, and set the radius to 0 (don't have f-stop selected from the drop-down). . yeah I wish there was 'turn off depth of field' checkbox to UN-check, but it looks like there isn't in 2.7x. There is a checkbox when you're using the new Blender 2.8 EEVEE render engine, but eevee's DoF isn't as accurate.
Thank you so much. It was a very good tutorial. But tell me, can I blur a scene with a background image and one object in front of it using this method?
I'm not quite sure what you mean. Do you want to blur the background image? if so, you might need to use compositing nodes to blur the background image before you underlay it behind the scene. Then your actual scene can contain depth of field to blur foreground elements. If you're not familiar with compositing nodes, I cover them quite a lot throughout my Blender VFX tutorial series.
***** it's fine, it is my computer, my CPU is rubbish but my Graphics card is great. So I can't really do much special except when it shows in game render, my games are laggy but their graphics are very good. I need a new CPU
DBoy Animations Have you accidentally changed the graph editor window to its 'drivers' sub-window? Find the pull-down(up?) menu on the graph editor's header bar to switch between F-Curves and Drivers. It should be on F-Curves.
You said the higher the f stop value the more the depth of field effect, it was already 5.6 when you changed to a f-stop, which you then turned it down to 1.8 so you decreased the depth of field and it all got blurry.
I have a question: Is it possible to use a amd cpu for cycles rendering? Because I have a amd cpu so a nvidia gpu wouldn't work or can't work together with amd
I'm quite sure you CAN use an nVidia video card in an AMD-CPU based computer. I'm an intel guy so I'm only about 99% sure. Blender Cycles can render with a GPU using a technology called CUDA, which is proprietary to nVidia. I've never actually been able to use this though because I don't have an nVidia card either.
Yes this tutorial is meant for use in an animated scene or a still render. In fact you can animate the position of the camera's target object to change the object that's in focus... Which is called doing a "focus pull"
I dont get it, Why are the shadows so smooth on your recording. Mine are just sharp black exact recreations of the model the are casted below them. And its not like you did somethiong: Your first render on the vid looked nice without setting anything up. Please can someone explain me what wizardry was taken here? xD
@@BornCG I thought this tutorial was for blender render not cycles. But if that is needed ok I guess I'll have to render in cycles? Is cycles better anyways?
Dulana Gunasena Thanks! Using this method works mostly fine so long as out-of-focus objects don't overlap with in-focus elements. If they do, there will be some funny sections where the wrong edge is blurred or in focus. #CyclesIsBetter :P
BornCG i use internal for minecraft since cycles is not needed for minecraft and takes longer to render, but ive used cycles many times for realistic stuff, so i use both.
VertiX I graduated with a Bachelor of Fine Arts : New Media.. in which we were taught/used 3DS Max, so I already had a decenbt start in 3D/animation. I started teaching computer summer camps after my 3rd year or so, and after a few years we started a 3D animation camp using Blender, since it's free and cross-platform. Over a few months/years I had a lot of opportunity to play with Blender, in fact I even dumped 3DS Max entirely after the Blender 2.5 refresh came out. Just lots and lots and lots of tinkering, learning from other instructors in-person and on youtube + the web, and teaching forces you to learn it really well. :)
Great explanation of the effect and how to use it. My only problem with the video: It's too long. You spent almost 10 minutes on creating the scene and going into detail, how you did it. Don't go into detail about basic blender operation, when you're doing a DoF-tutorial. Keep your videos as informative, but also as short as possible, don't make it any longer than it needs to be. Otherwise, some viewers might click away because they don't want theie time wasted by stuff they already know. Btw, do you know how this effect can be created in post with the renderlayer nodes? I was looking for some information on how to 'cheat' by simply using a blur shader and then setting the intensity based on the distance from the camera, but I couldn't figure it out myself.
The entire reason I looked up your tutorial was because it was Blender 2.7 and my pc wont run the newer versions... so now you upgraded mid series, and I have no further info for these categories??!!??
My blender 2.7 tutorial series runs from #0 to #87. This is #45. All the tutorials on my channel with the orange lower bar in the thumbnail use Blender 2.7. 🙂👍
But in this video you upgrade to 2.74... no longer 2.70... even 2.71 will not run on Dell laptops with an i5 processor or lower. So after this video certain things stop being valid to anyone in a similar situation to me.
It’s important to note for anyone else reading this that Dell laptops with i5 processors have gone through over a decade and 13 generations / iterations of processor models. Newer i5 models (since about 2014) can run newer versions of blender just fine. For Cace, I would say: most features / aspects of Blender don’t change between small versions of Blender. Most tutorials using Blender 2.74 will work exactly the same in version 2.71. I really wouldn’t count yourself (or my tutorials) out until you actually run into a difference you can’t get around, or if I mention at the start of the video that it’s a new feature as of that or a very recent version. Example: Bendy Bones (for more advanced character rigging) did come out as part of Blender beyond 2.70, but most of Blender is the same throughout 2.7x.
Best DOF in Blender explanation I've found. Thank you!

Amazing tutorial, probably the best explanation of DOF I've ever seen.
Thanks!
Yeah I will agree with others, one of the best DoF tutes I have seen. Now the subject is much clearer :)
Very Very useful video ... u are a very good teacher on youtube unlike other tutorials ! keep up the good work !
This is exactly what I was looking for. Well explained, clear and not beating the bush. Thanks bud.

Thank you so much, my renders are *much* better now. The blur just makes it so much better, god.
Excellent tutorial with great explanation. Thank you for posting !
Almost up to 100 thousand subscribers.....keep them coming. Great explanation for depth of field!
the way you explain things is very very clear, thank you for your effort !
Thank you. Very helpful. I wonder how can you write so many number of good videos. You are great!

HA! Radical!
Nice tutorial. One question... I'm running 2.74 and there is no aperture setting in the depth of field section.
You can also get DOF effect with a larger scene scale by setting the F-Stop to a very small number (e.g. 0.001).
Love your tutorial series, will you be doing newer ones? With 2.8 possibly?
Thanks! I have already started my 2.8 tutorials with an overview tutorial on blender 2.8 beta! Check out my channel page. 🙂😉
AWESOME!!! Thanks!
This is what I'm looking for in my current render. But my question is, is the depth of field function still buggy even in the stable release in 2.74?

how do you make the depth of field span over larger area? i tried making an empty cube and enlarging it but to no luck
BornCG
Thanks man...
Does this beautiful technic works on bigger objects? I would like to use it on models that are in a cool position and such and use the blur so can add drama or similar. Is it possible?
Yes, in this tutorial I cover how to adjust the scale to accommodate larger scenes I believe.
@BornCG Please help, how to remove Depth of Field (Camera Focus) on my blender project??
In the Cycles render engine? Blender 2.7x? --> Select your camera, and in the Properties window > Camera Tab > section: Depth of Field .. de-specify a focus object, and set the radius to 0 (don't have f-stop selected from the drop-down). . yeah I wish there was 'turn off depth of field' checkbox to UN-check, but it looks like there isn't in 2.7x.

@@BornCG thank you, but I found out that bluring the background image at photoscape before importing to blender is easier.
Everytime I select the depth of field, blender shuts down on me. is it my computer or the version of Blender I am using? I'm using Blender 2.75
***** it's fine, it is my computer, my CPU is rubbish but my Graphics card is great. So I can't really do much special except when it shows in game render, my games are laggy but their graphics are very good. I need a new CPU
Thanks, very interesting... I'll watch it again for you speak very fast for me ;-)
can you do this is blender render?
I have a problem that sucks -.- I want to see my animation in the graph editor but the isn´t any curve. I can´t see curves although I made keyframes.
DBoy Animations Have you accidentally changed the graph editor window to its 'drivers' sub-window? Find the pull-down(up?) menu on the graph editor's header bar to switch between F-Curves and Drivers. It should be on F-Curves.
If I go to Animation layer I can see the f curves but thanks ;)
how to exclude the sky?
that it is not blurred?
You said the higher the f stop value the more the depth of field effect, it was already 5.6 when you changed to a f-stop, which you then turned it down to 1.8 so you decreased the depth of field and it all got blurry.

+DBoy Animations There are no problems with AMD CPUs working with nVidia GPUs.
Fantastic Fanboy
I know xD my AMD CPU und Nvidia GPU are working fine :D but I didnt know this at this time ._. XD
I have a good question! What if you want to give the camera a sorta fish eye effect? (like you might see in a rap video or something)
+the lone gamer Blender Game Engine can make fisheye camera effect
You can do that in the compositor or by changing the camera's Focal lenght.
The outro song was made in fl studio. Knew it only by hearing the claps.
I have a question... can i use (depth of field) in blender render ???
Yes you can, but it's accommodated using compositing nodes, and the result isn't quite as good.
@@BornCG thank you 🙏 I will try
Is it the same way to use this method in an animated scene?
Yes this tutorial is meant for use in an animated scene or a still render. In fact you can animate the position of the camera's target object to change the object that's in focus... Which is called doing a "focus pull"
It bums me out that blender keeps changing how you do DOF. because with my version I don't have the same options... :/
+CuffRox you need to switch your render engine at the top from blender render to cycles render. 😊
I dont get it, Why are the shadows so smooth on your recording. Mine are just sharp black exact recreations of the model the are casted below them. And its not like you did somethiong: Your first render on the vid looked nice without setting anything up. Please can someone explain me what wizardry was taken here? xD
Speedhog22 The cycles render engine. :) .. and you'll know from earlier videos that I generally use fairly large area-lamps.
BornCG Oh.. uh thanks :D, I did just found you since i posted that comment because i searched for tuts on the dof effect. :)
7:42 "We have our scene"... LOL... now tutorial begins ;).
thnx
I have no appature in my menu wtf........
Have you switched to the cycles render engine?
@@BornCG I thought this tutorial was for blender render not cycles. But if that is needed ok I guess I'll have to render in cycles? Is cycles better anyways?
Will this work with Blender Render?
***** nope. There is a way to do it with the old render engine using post processing nodes, but it is kinda faulty because it is done in post.
