RGB-Max

Hi,

When comparing the results of the automatic image optimization “multi automatic” (D) I´m always wondering what effect RGB-Max has. Especially when switching back and forth from the optimized images to the original, I typically don´t see any optimization effect for RGB-Max. What´s the reason for this?

Regards,
Ben

Hi Ben,

RGB-Max is an automatic image optimization option build in PhotoPerfect, which stretches the tone values of all three channels (Red, Blue and Green =RGB) to a maximum. Please also see this post about histogram:

Histogram - what for?

RGB-Max is best suited for under-, overexposed photos or just photos with color cast, as these problems would be corrected by stretching the tone values.

If your photo is however correctly exposed, the tone values would also in most cases have been evenly distributed over the complete range already, so that RGB would not have any or only minor effect.

Best regards
