Why Brightness Drops When You Cut Saturation? - HSB vs HSL

Every time you decrease the Saturation with the Hue/Saturation adjustment in Photoshop, the "Brightness" value decreases. In this lesson, we will understand why that happens and explore the root of the cause by learning the differences between HSL and HSB color models. This tutorial will cover almost everything you need to know about how the color models work and how saturation, lightness, and brightness work in conjunction with each other.

I hope this video helps you. Thank you so much for watching :)

we surely want another episode about difference between lightness&brightness! please 😊

[whatTheblue]

Such a detailed video, it felt like a college lecture but in a good way 😅, thanks a lot Umesh for such videos

[punipun]

This is very interesting! Thank you for making this video!

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.

The most genius explanation ever on an online platform 👏 🙌 👌 👍

Very rich in information! Thanks a lot Unmesh for covering this subject! Good luck man!

[marktamparong]

Wow this channel just went down the rabbit hole. Thanks Unmesh!

[Heiko_K]

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.

Please create a dedicated video on differences between Lightness and Brightness. Thanks a lot for your videos.

[Scott.Sandifer]

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!

[marklutnes]

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?

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.

[merijung]

This was a great technical based lesson tbh. Thanks man!

[berat]

Thanks for answering my question :) It is totally make sense right now and also I learned that there are a LOT to learn over there. Thanks :)

[renderdriver]

Great video! I love the way you explain!

[Giooge]

Now I understand well why we are using a grey solid color adjustment layer as a brightness check layer, instead of desaturation.

[Enra]

unmesh still going strong with the grind! 💪

[i_shubham_mehula]

damn... this solved my greatest problem...i used to tweek the brightness and contrast everytime i decreased the saturation

[parthapratimhalder]

Nicely explained, Thanks. Please make a another video about Brightness vs Luminosity for us.

Ur just awesome..learnt something new today
