As a prepress person, I learned about 'grey component' of a colour, which is the description of loss of saturation in rgb or cmy... That concept adds some clarity to saturation loss.
Wow! Thanks to the Turkish fellow for even catching this and thank you for finding and explaining the answer. First question that comes to mind is could understanding this make a difference in how we might work color on images? The second question is, in converting images between black and white and color, in either direction, does HSB limit the conversion?
It helps you better understand how HSL works when you are working with the Hue/Sat Adjustment and how HSB works when you're picking colors in Photoshop. Understanding both models also makes it easier for you to work with other design programs that give you the option of RGB, HSB, and HSL, among others. Neither HSB nor HSL limits anything; both have the full range of colors, and the difference is how the values work together to bring a particular color.
thank you for this video. The question lingering for me, after having understood the difference, is the purpose of it all. Why do these two models exist? what is the practical usefulness of having these two color representations? and why does Photoshop mix the two up when choosing and checking the values, which in turn lead to this confusion? Thanks and have a great day, Heiko from Germany.
Hey, i am not sure, but i guess it's for real or unreal editing of colors. In real world the saturation of colors decreases with very bright and very low lights. When editing photos HSL can help in achieving correct colors. HSB would be for a more artistic and unreal approach. Greetings
@@ABCprogamerXYZ thank you. I get it. although it's not really important since I don't work in a way in which the values are important to me, I still wonder why the saturation tool then uses the hsl model whereas the color picker displays the values via Hsb (or was it the other way around?). but as i said, not really important I was just wondering...
Hi Umesh, Two subjects I like to hear your story about: - Good monitor for photo editing only (2K vs 4K, do you need a 4K?, colour calibration hardware vs software etc, what is 'good enough' for us enthusiasts). - Sending of for printing (colour gamut warning, ways to solve it, proofing etc etc, what to ask printer companies). Again, not overly complex or super expensive. Just 'good enough' for great results. All within a medium budget range. You know what I mean ;-)
I love all of your videos and the way u talk especially now a days... i was looking for Years for these three things/videos in Ps (1) Save your photoshop life with three history tricks (2) what is overscroll in Photoshop and (3) Disable this for faster retouching in photoshop. Thank You and tons of LOVE from PAKISTAN
I learn new software and workflow techniques in all of your videos. But this one had some excellent explanations of theory. Absolutely phenomenal teaching style. Thank you so much for what you do!
Thanks for the video, very useful information. Please make dedicated videos explaining which tools use Brightness and Lightness in PS. It seems Hue/Saturation and Desaturate (CMD+Shift+U) uses Brightness, but gradient maps and Blend If uses Lightness. Maybe that information can explain the differences when converting the same image to B&W using the different alternatives.
You are sooo good at this, love the channel, i don't usually comment yt videos, but just had to let you know the effort and passion you put into these is quite inspiring and very apreciated.
I have a technical background so I'm used to interpreting these kind of diagrams, and I think you've done an excellent job to explain this in plain English and demonstrate it with visuals. Loved the video!
I have been teaching color theory for a few years, in a physical way, but now that I am starting to teach color in digital media this will help me a lot, I had never considered that difference. Thank you very much Unmesh! I love when you explain theoretical concepts!! Do you have any video that talks about color LAB? In addition to the web you shared, how to use it in Photoshop? Thanks!
What helps me remember is HSL is like a bright white light in your face that won't allow you to see colors at all in your surroundings unless you dim or subtract light. And HSB is like a white paper in your face that allows you to add ink or paint until you get saturated colors. Kind of reminds me of RGB vs CMYK, or additive vs subtractive colors.
What would be kinda cool, is a picture that transforms itself into two completly differant ones, if you go back and forth between complet desaturated and color. Differant Hues can still have the same look in gray, so a picture could evolve into a complet differant one, as soon as it gets more saturation.
If you pause whenever the color picker is on the screen like say at 1:41, you can imagine the HSL double cone and the HSB cone represented in the main square. It just takes some creativity in folding it with your mind. To imagine the HSL double cone, you pretend that the leftmost black point is moved all the way to the right and the square is no longer a square; it's a right triangle now. You're looking at a slanted representation of a section of the HSL double cone, with all the greys having been moved to this 45-degree diagonal and all the saturated colours sticking out in varying distances from the grey axis. The distance being the saturation of course. Now to view the HSB cone what you do is, instead of moving the leftmost black point all the way to the left, you move the rightmost black point all the way to the left. This cone is not slanted like the other one; it's standing straight and the grey axis is vertical. Another way to go about this entirely is, instead of imagining sections of cones and double cones, just reset and look at the square we started with. Luminance is vertical and goes from the bottom of the square to the top vertically so values are mapped horizontally (i.e. 50% on the vertical scale of grey is the same height as 50% on the vertical scale of any saturated colour), whereas brightness is L-shaped and follows half the perimeter of the square, going from the rightmost black point all the way up and then all the way left to white, so mapping is slanted 45 degrees (i.e. 50% grey on the diagonal scale of grey is the saturated colour on the top right colour because we're tracing lines diagonally).
Wow...I think a more thorough video will be awesome! Showing some examples in photos and illustrations! :D I can't remember which model I use, I just use whatever is right there in PS by default. Ha ha! But, now that I see it there, that's amazing and still a mite confusing! So when the brightness is 100%, but I have a somewhat saturated colour, that will end up looking darker because, of course, that colour is darker than white. I'm sure there's WAY more to it, but is that kind of on the right path?
Sometimes it is very confusing when jumping between HSB and HSL. Why not to get rid of one of the model altogether😅! HSL for me feels more intuitively understandable.
Hi Umesh Super good information. Always you are great. I am indian wedding photographer when I edit .cr2 files in Adobe Lrc color bleeding is big problem. How to increase saturation without color bleeding ? Please this is a problem for many photographers.
Instead of defining saturation as colour intensity I find it easier to define it as how much grey is added. Then lightness is how much black or white is added.
Thanks for this video, very interesting. This made me think what's the best (and proper way) of making an image black and white so to retain the values of the colors. Looks as though this adjustment layer is not the way to do it. Could you help with that?
Awesome channel thank you! Do you happen to have a video on adding smoke to a photo? Say I have a person with a cigar or a vape pen how to add smoke / vape that looks realistic?
If ling ling can practice for 40 hours a day, Unmesh can make video on the same day as well as edit it on same day and upload it on the same day with best quality of course. Unmesh is ling ling of photoshop. 9:57 you can see that the date was on 3 May 2:20 PM.
And why was not a circular wheel to be placed in the program in order to match the explanation it provides? A wheel had to be put if it seemed like this And why were these two systems set? If the difference between brightness and lightness is explained, it will be easier to understand more
Technically, on a screen the image gets brighter not less bright. As a display is made up of red green and blue subpixels, fully saturized red would be 100% red color 0% blue %0 in other word the screen produces / lets trough 33.333% of the light. So the 50% brightness gray is brighter than the original red, even if it may not seem that way.
Hello. Thanks a lot for this outstanding video! I would like to know why do we use HSL adjustment instead of HSB(V) or is there any HSB adjustment? And by the way... is there any way to adjust the saturation using curves? THANKS!
Hi Unmesh, I am posting this here because I cannot find a way to comment on the latest Type Fonts video. I love your videos but not the way the latest one on fonts is displayed. I don't understand what is happening with the video. It is very fast and does not have the normal progress slider so I can look at any portion of the video that I want. Also it is on a rolling screen where it shows other people's videos. I do see where a smaller window is available where I can use the slider but the window is very small. I really think this is a step backward from your normal videos. Tom
I dont where this guy goes to find out this information. Its like he has some secret manual he can refer to that no one else has access to. He also seems to be talking about all these subjects without reading from notes or telepronter. Very impressive I couldnt do that even on topics I know inside and out
