Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
No, the scale of 0 to 255 is not interpreted as linear to the DISPLAY. It is interpreted agnostic internally. So when you have two layers, and you multiply them, so for example, red and grey: Red = (R=1.0 G=0 B=0)Grey = (R=0.5 G=0.5 B=0.5)R = 1.0 * 0.5 = 0.5G = 0.0 * 0.5 = 0.0B = 0.0 * 0.5 = 0.0Red*Grey = (R= 0.5 G=0.0… -
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… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
I am on Maya 2015. I believe that drop down isn't available till 2015 extension 1 ( part of the new color management updates ) Was hoping there was a similar color setting like in photoshop that affected color blends ( as 3d texture paint and paint effects give the same artifacts by default ) Last I heard on the Mudbox… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
I don't think you get what i was asking. Of course i know what gamma is and how the maths work. I'm just talking about implementation. The question is that if the rgb scale is internally linear, why would the blending algorithms ever have a chance of being wrong? Because gamma is just a way of transforming the linear scale… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
Hmm. That photoshop trick is interesting, but after doing some quick tests, it seems the issue(s) seen without "Blend RGB Colors Using Gamma" checked are only really very noteworthy if you're blending starkly different colors with a very soft brush. If I'm using a soft brush to blend anything, it's probably blending a… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
ehm i cant achive the nice blending shown in the end of the video. i went in to the colour settings, changed "blend rgb colours...." to 2,2. didnt make any difference. any photoshop pro care to help me? -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
Using soft brushes with full chroma colours is the easiest way to tell. Colour blindness is only really a problem at lower saturation. (i have Moderate Deuteranomaly, or common red/green and blue/purple mixup) Painting in lab is horrible btw. I agree. It's a mathematial construct designed for the widest colour gamut… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
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… -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
You can change Photoshop from RGB to Lab to get correct bluring without changing any of the preferences. -
Re: Computer Color is Broken - a short video on colors, displays, Photoshop, and blurring
Yeah, ninedegreesbelow is a good read in general, Elle Stone knows a LOT about icc profiles. It's very subjective what is the best, though I know there's painters out there who prefer working in linear because that keeps the luminosity of their colours easily in tact. Others instead have become so used to compensating for…
