congratulations on a greeat picture viewer. This could be the most useful tool in my image workflow.
Unfortunately, one must-have feature is missing: To highlight overexposed areas!
This determines a good rating or a deletion candidate or a picture that needs output in black and white. Also, in an exposure bracket row, this determines the one to keep and the two deletion candidates.
The histogram is not sufficient for this purpose. I don't care about blown highlights in light sources or reflections. I do care about blown faces.
Ideal would be blinking in the color of the overexposed channel. Green blinking means green channel is at 255; white then means all channels are at 255. This is helpful to determine whether a portrait is useful. Red blinking in a face means red channel is overexposed, so from a raw picture, one can still obtain a good bw shot by using the green and blue channels. White blinking in a face means that all channels are overexposed, so this is a deletion candidate.
Highlight blinking should be enabled with a key. This allows for highlighting over- and underexposed areas still with color information.
For a first cull of images, the three things to check are overall image quality, sharpness and correct exposure. At present, FPV covers two: The sharpness check is the best on the market, FPV's speed makes it also the best tool to assess overall image quality. Just the exposure is missing.
What do you think?
