Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
Ah sorry. Because people don't like spending ram on a 16bit image. At the least, that's why Adobe Photoshop probably does it. I imagine it went like this: Customer: Adobe, why can't I have linear blending? PS engineer: Well, if you go 16bit, you can have it and it won't look ugly. Customer: But then my images take up twice… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
For people talking about the smudge tool in Photoshop, it appears that the tool itself has linear mixing hard coded in. So using 'sample all layers', or smudging two colours on the same layer will not respect the setting in color preferences. It makes a difference when photoshop is doing a real-time mix (eg opacity through… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
I'm also having trouble understanding why the conversion is necessary. From what I've read, in the case of alpha blending, it's because the colours being blended are not linear. These RGB values that we select to paint are not linear. When we want a linear gradient of value, this is what we expect: But monitors don't work… -

The issue with linear tone response curves, is that they don't really work well in 8bit to begin with. You need 16bit to prevent banding, it's why the srgb tone response curve was introduced in the first place. I would't recommend using lab for painting though. Photoshop does all sorts of cheats to make lab seem like it's… -

So it works for soft brushes, but gaussian blur still makes an ugly dark line for me in CS5. Using LAB mode however does fix it for guassian blur too. -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
on a side note... Coming from traditional media years before I considered painting would really be possible on computers it at first took me a long time to wrap my head around using sliders or simply droplet selecting hue value and sat. And what was a correct blend between two colors is different when considering the…
