Aa. For me too. How come, yellow is more difficult to get perfect. Is it the complexity of that color? Anyway, it's great to practice color knowledge and how to apply them.
@@f64Academy Blue was the hardest for me to get, but I went one step more and did a combination of two colors as well, with 8 colors total using Curves. This exercise reminds me of RGB Rush, a video game on steam. You use RGB dials to match the color, which acts like HSL/HSB. I play it to better understand color, but it could be helpful to mater painting with curves.
I agree... I had to reset all the curves multiple times to get yellow correct. I created four copies of the Mask layer and have saved four layers named for the required center target color, so I can go back and look at the detailed solutions in a week or so to refresh my mind as to how I solved the exercise. Great exercise! Thanks for the puzzle... now I can sleep.
All done in a few seconds without any problem. I'm partially color blind, so I use the eye dropper tool A LOT anyway. Click with shift pressed on all colors + gray, to get RGB reading in Info panel. Then use R, G & B curves with mouse to get roughly to the same point for gray and destination color, then use arrow up/down to fine tune :D
Thank you. It’s the first time I have a normal, clear and understandable explanation how to use the curves. Till now I was using them intuitively, had now idea what I did right when the result was good or what I did wrong when the result sucked, and mostly avoided using them.
This is a brilliant, easy to understand, effective way to learn how (and why) to use color curves! Normally, it's hard to get a good grasp of color curves using "normal" images because the goal is usually subtlety. What you've done here is, to me, similar to what you accomplished teaching blending modes. You've enhanced my game enormously - thanks again!
Yes! I love this comment! Thanks :) This one was very difficult to put together. It took about 3 days of just thinking about the video's structure. To hear your comment made all that work well worth it!
You sir are a scholar and a gentleman, since watching your channel I've really started to understand more about 'clever' editing rather than the ham-fisted techniques I was bludgeoning my images with. Thank you, and look forward to all your future content 😁
I have been using the color curves for some time. They are my first go to way to color grade my images. Watching this video I now realize why I like using the color curves--I can add color that is not in the image. Not limited to adjusting colors that are already in the image. Thanks for taking my understanding up yet another notch Blake. And now that we can use masks/selections with curves in ACR we can do this kind of color painting in ACR.
Glad it was helpful! I've been using these for ages with the ZSE, as you know. But gosh, trying to explain them in an understandable way without sounding like a color scientist on a high horse.... that took me a LOOOOONG time to put into words with practical application. For those who think making videos like this are easy, phew... this one was a challenge! Glad you found it helpful, hearing that from you made my day ;)
@@f64Academy you did it. Even me, not an English speaker, understood. I feel as if I won a lottery. Finally I know what I’m doing when I’m playing with curves!
Blake you are a brilliant teacher . This exercise is what we need to practice and understand further about color - so so important working in Photoshop ❤
Dude this is awesome! The video was brilliantly scripted and edited. Pro knowledge perfectly explained. Sub + New Fan right here. This will rocket my game for sure. Cheers from Buenos Aires!!!
Giving small exercises around a UA-cam tutorial like this is such a huge upgrade over just "do this" or "do this and here's the PSD" style videos. Gained a sub. Great work.
Nice explanation. I would add that it can sometimes help to change the curves layer from Normal mode to Colour mode so that the curve isn't affecting the luminosity. In Normal mode, adjusting the colour curves does alter the luminosity values and that can create a strange effect when the layer is masked. Changing it to Colour mode leaves the luminosity values alone so the luminosity of the masked area doesn't change. It's not always necessary but I photograph wildlife and often adjust background colours using this technique when I don't want the luminosity of the background to change at all. Thanks again for the video.
That's a great point if it's only about color alone and not changing the luminance. I've found that sometimes normal looks more natural when it comes to editing color curves. But it's an image to image basis kind of thing.
@@f64Academy Absolutely - it depends on the image and what you're trying to do. I normally do the colour curve in normal mode first and if I don't like the luminosity change then I try colour mode. For my images, I go with colour more often than not because changes in tone can really show up on wildlife. But for other styles, normal may work better more often. I also find this technique really lends itself to working in Lab - but that's a whole other ball game!
Excellent explanation demonstrating how curves work and how to put them into practice serving their purpose. First time I actually feel comfortable using curves. Many thanks for this contribution. Always looking forward to your teaching.
i wouldn't call it "perceived color", it's a color appearance model(CAM). its just the fact that RGB curves is a different color model than HSL. HSL just happens to depend on the hue cone, while RGB curves will modify a grey color. (as grey is a color, hence why D65, D55 exist etc.) and offsets the balanced greyscale.
I totally see what you mean. I was battling with myself on how to explain it in a way that is understandable and relatable, you know. I may have been off in my idea. Thanks for clarifying it.
Masterclass! I am used to using the tone curve RGB) to affect luminance, but haven't yet explored the individual channels to change color. Your lesson makes it very understandable and approchable.
Thanks Blake. Especially for the reminder to do obj selection and apply specific color changes with curves…being able to do that in LR would be great given the power of the newest obj selection tool.
I found this video excellent and your step by step explanation invaluable. I also like how you applied the theory to an actual image. Thank you for taking the time to teach us. Please keep tutorials like this coming as I like to understand why these changes happen to my images when I use photoshop adjustment layers. It really helps newbies like me.
Great explanation re: the color curves. I've used the different curves a few times with mixed results. I watched other videos never fully appreciating the technique. Thank you and yes, we need to drink your coffee blend
Glad it was helpful! Skip the coffee... the secret is tea. I prefer Earl Grey, when I feel like getting REALLY crazy I'll add a splash of Lavender syrup to it ;)
Thank to this awesome video I will try to use the color curves more , before its seems too complicated. For me the yellow was a bit more of challenge to get it right!
Great stuff, enjoy the work you do. I am studying curves and am discovering components to it that I haven't seen anyone else talk about. There is more to this great tool and I agree with you that's not being used to its full potential. Next year some time I will reveal what I've uncovered.
For sure! I typically don't watch anyone elses tutorials. That way all I know is what I do and what I discover and its not influenced by others. I recommend you and others watch them to get multiple perspectives, I just prefer not to for the originality of my videos.
@@f64Academy I can understand that. I kind of wondered if that happened or not, but makes perfect sense. I do watch so many others. I've calculated all the videos I have in my save list that if I watched them all, it would take me 30 straight days to get through them all. So far though, I've made insights that I think, like you, will allow me to stand out when I'm ready to share them. I love to teach.
Hey! Great vid. Have been trying to explain how useful curves are to friends for years. Just a tip: you might want to turn the shutter speed on your camera down to something < 1/200. Currently it's very jittery, especially at the start.
@@f64Academy No worries! It's something to do with the camera capturing individual moments in time so quickly that it doesn't look natural to our eyes. Best practice is to have a 'shutter angle' of 180°, which basically means your shutter speed is double your frame rate (25 fps = 1/50, 30 fps = 1/60). Due to lighting, aperture preferences, ISO settings and availability of ND filters it's not always possible to get it this low though, so anything below 1/400 tends to be a little easier on the eyes (1/100 is my go-to!) Hope this helps!
When we first started learning Photoshop and curves while in my career at National Geographic, we hired a Consultant who demonstrated he could adjust an image not by looking at it in color but by just using the numerical values in an image then adjusting the numbers to color correct.
@@f64Academy That's what I love about ACR/Ps, everything is just a little different for each other that there is always a creative solution for your tasks. Like you, I hate that there is a misrepresentation of tools, such as Curves not showing the two colors as you mention, or BlendIf as well.
Thanks for your creativity and for bringing fun into education for me :-) and competition with myself....perfect knowledge, additional values, opening fantasy how to use with other tools and not boring....
Great explanation as always. Do you think this is similar on some level to what Calibration does in ACR? I mean, what that affects is also not based on the resulting "color category" an R+G+B color value falls into (what you refer to as perceived color), but the R, G, and B components of each pixel.
Nope, very different applications. Curves will straight up add color where it didn't exist. Calibration is still based on the existence of color, but more on visual perception of color to match the human eye. It's hard to explain, maybe another video about color and what is affected by what.
Thanks so much! 😊 Sometimes you have to look at these things through a different lens. The benefit of being a painter before I was a photographer helps me look at these tools in ways most people don't. I highly recommend photographers study multiple disciplines to see outside the box.
@@f64Academy I like that, I wish I could paint, I have been trying to learn how to paint photos with photoshop and topaz and I am starting to get the hang of it. Photoshop allows me to let my creative side come through with an extension to my photography. I love getting all the tips from you as well. Thank you
Coach, you lost me at "This is a football". You've guaranteed yourself a small bump-up in views because I will need many to get this anywhere near understood and automatic.
At 11:42 why didn’t you go into green and add green? Adding green would technically be removing purple Edit: that’s how I understand the curves filter works. You can add and subtract colors. If an image has red cast, add cyan. If it’s green cast add magenta. Add an opposite of a color can be viewed as removing said color Edit2: by adding yellow you did you really remove the purple cast?
Ah yes, all great points, but I think you are looking at it too literally. By saying "act like a painter" I was alluding to the colors that were already in the image and mixing them with new colors. So I used the colors in the image as a base but mixed in yellow to make those colors that were already there appear more orange. If I want to remove a color cast, you are spot on, but if I want to use the color information that is already there then I blend in other colors.
Wonder if one could use the rgb values of one color to figure out how one needs to add or adjust to match colors/color casts? Think matching skin tones or some things like that?
This gives a lot of great ideas for coloring. A question: When manipulating the curves, I often find it easiest to move the upper right and lower left points to add the color (e.g., in the red channel, move the top right towards the left to add a lot of red; the line remains straight even though angled). Is that a bad thing to do?
No it's just a different method. Dragging in from the corners clips the channel to create the color where the curve manipulation stays within the constraints of the channel to a degree depending on how far you take them.
you are able to match the colors with hsl & selective color adj layer. at least i did. so i don't get it why curves adj are more powerful then the rest?
True, but Curves gives you color in highlight midtone and shadow independently. HSL is just more or less color here or there with no real emphasis on tonal variations. It's not as evident in the test image because the color is just one color and one tonal variation. But apply that curve to an image with three points and you now have a tool that HSL cannot compare to.
@@f64Academy you are right for the hsl vs curves. curves keeps the tonal value. but curves vs selective color, well that is a diff story, cause selective color can compete with curves :)) i just tested, i can send you some screenshots
@@anajakimovska7394 to a degree yes. But they are very different tools with different applications. Selective color still cannot target the individual tones within a color channel as it targets physical perceived color and not the channel color data. So curves can still make the image have more color just in a highlight while maintaining midtone and shadow integrity. Selective color can only do that in conjunction with blend if or luminosity masking. I'm well versed in selective color, it's one of my favorite, if not absolute favorite, for color grading. However it is very different in application from curves.
I think you're using the wrong language here. When working in RGB Channels, you're never "adding" color, you're subtracting it. When you opened the canyon image, made the selection, then adjusted the blue channel, you said that you're adding yellow. This is incorrect as there is no yellow to be found in the blue channel. What's happening is that you're subtracting an amount of blue from that channel which allows the other colors to dominate more, producing the yellow. Also, looking at the blue histogram, there were no "highlights" to be adjusted... all the values were mid to shadow. I appreciate what you're doing here, but please remember that you're teaching countless users to believe that they're adding colors to a channel, which totally isn't possible.
Right and I appreciate that 100% the language I'm using here is not adding color to a channel, it's adding color to the image by manipulating the channel. I'm trying to make it easy to understand without making it overcomplicated. I'm not talking about adding color to a channel, when I say adding, I'm just talking about the effect on the image.
So, how'd you do? Did you match all the colors? For me Yellow was the hardest to get perfect.
Aa. For me too. How come, yellow is more difficult to get perfect. Is it the complexity of that color? Anyway, it's great to practice color knowledge and how to apply them.
@@frankennick I felt it's because of it's lower luminance than the other colors. But that could be me.

It's not as evident in the test image because the color is just one color and one tonal variation. But apply that curve to an image with three points and you now have a tool that HSL cannot compare to.
@@f64Academy you are right for the hsl vs curves. curves keeps the tonal value. but curves vs selective color, well that is a diff story, cause selective color can compete with curves :)) i just tested, i can send you some screenshots
btw thanks for all the knowledge you are putting it out there! i learned so much from you!! :)
@@anajakimovska7394 to a degree yes. But they are very different tools with different applications. Selective color still cannot target the individual tones within a color channel as it targets physical perceived color and not the channel color data. So curves can still make the image have more color just in a highlight while maintaining midtone and shadow integrity. Selective color can only do that in conjunction with blend if or luminosity masking.
I'm well versed in selective color, it's one of my favorite, if not absolute favorite, for color grading. However it is very different in application from curves.
@@anajakimovska7394 my pleasure 😁
Can you please help matching skin tones via shadow/highlights/midtones? Many thanks for considering my request.
Not sure I know what you mean.
@@f64Academy I mean that if you can share video matching skin tones
:D :D :D Awesome!
I think you're using the wrong language here. When working in RGB Channels, you're never "adding" color, you're subtracting it. When you opened the canyon image, made the selection, then adjusted the blue channel, you said that you're adding yellow. This is incorrect as there is no yellow to be found in the blue channel. What's happening is that you're subtracting an amount of blue from that channel which allows the other colors to dominate more, producing the yellow. Also, looking at the blue histogram, there were no "highlights" to be adjusted... all the values were mid to shadow.
I appreciate what you're doing here, but please remember that you're teaching countless users to believe that they're adding colors to a channel, which totally isn't possible.
Right and I appreciate that 100% the language I'm using here is not adding color to a channel, it's adding color to the image by manipulating the channel. I'm trying to make it easy to understand without making it overcomplicated. I'm not talking about adding color to a channel, when I say adding, I'm just talking about the effect on the image.
I can do better than you 😂😂😂....I'm doing this when I'm in 8th standard.
Lol!
Excellent
Thank you so much 😀
