OpenEXR files are commonly used in CG these days, and they have floating-
point numbers for each pixel component. They also allow for more than 3-4
pixel components. The values still have their usual meaning, with 0 being
full black and 1.0 being full white, but the values are allowed to go
outside this range to avoid clipping of dynamic range.
GIMP’s GEGL pixel engine deals natively with such things. Photoshop needs
to use import/export filters which inevitably lose quality. This is
probably why Adobe products are not used much in VFX work.
