I've been doing microstock photography for quite some time. The most popular images feature bright, almost high-key tones with vibrant colours.
My skills have improved dramatically over the last 4 years, however I'm still not certain about the white part of the histogram, from level 240 to 255.
The thing is, the image can look absolutely great on my calibrated Dell 23" monitor with all tones present, but when viewed on any other screen (laptop, tablet, low-end monitor, etc), it can appear almost too bright with blown highlights. This is especially evident on low-end monitors where the brightness depends on the viewing angle. Some monitors just cannot show the finer detail in the highlights and/or shadows. The things are even more complicated when converting from ProPhoto profile to srgb, since all images get additional 10-15 levels, especially in colour channels, as SRGB has pretty narrow colour gamut.
Since I'm selling the images to zillion potential clients, not all have state of the art monitors or even calibrated screens. My question is - what's the general "safe" zone for the highlights, so they can appear well on most screens?
