Each channel is stored as an array of floats. Float is stored on 32-bits, so it means 96-bits per pixel in RGB or LAB mode and 128-bits per pixel in CMYK mode. (GIMP uses 24 bits per pixel (8-bit channels), many other applications use 48-bits per pixel (16-bit channels), 96-bits per pixel can be achieved in RawTherapee and in G'MIC).

Each operation can be adjusted at any time.

Result of each operation should be immediately visible on preview.
