Hi

I want to specify the kind of photos to be used with my brand guid but in scientific way, so what diagrams to use to specify that ? will histogram be enough or any other diagrams or values and properties ? so i can specify like the light values white color values color and gray percent values ?

Kindest Regards

You may have to be more specific, give examples, …

The Histogram may not be able to do what you expect it to do, see these examples – identical Histogram, different appearance:

Thanks allot so you have any suggestions ?

Please give examples of the imagery you are talking about so the unifying properties may become clearer.

Something like this, or grays degrees but mostly light like second picture.

Kindest Regards

One of the images appears to be fairly neutral but to actually still have color (see screenshot) whereas the other one is truly neutral. 

In the case of the truly neutral one the Histogram would provide a more meaningful orientation, but I wonder if simply calling for »high key« images might not be about as useful as any more convoluted or involved description.
