How do I input color values in sRGB space?
I am learning about the sRGB color space in OpenGL.
One thing is colors from textures, but other - direct color values, let's say from graphics editor.
A color component of 0.5 means that the output on the screen will be a lighter color, 187.

sRGB gamma curve implement in tensorflow
I need to implement sRGB gamma curve in tensorflow. But I can not compute the element wise condition in tensorflow.
In sRGB curve, if the value is less or equal than 0.0031308, it is a linear operation: x*12.95
If the value is greater than…

Do I need sRGB v4 or sRGB v2 when exporting to the web?
Before exporting my image to the web, I want to convert them to sRGB and then remove the sRGB profile from the image (to reduce it's size, as sRGB is the default profile to use if there is no embedded icc profile). I was thinking that there is only…
