- nness 5y agoI assumed the interpolation of gradients isn't a matter for the colorspace?
- gmueckl 5y agoThe problem is the non-linear conversion between sRGB values and actual displayed brightness. Some operations have physical equivalents (e.g. transparent overlays can be defined equivalently to viewing a background through colored glass). If they do and you use textbook physical models to implement them, you need to also use linear intensity values to get it right. A lot of code out there ignores this.
- vanderZwan 5y agoDoes it becomes obvious that it is a problem when I point out that using sRGB color space means we do linear interpolation of values in a non-linear space?
