I've not been able to get any of the suggestions working due to lack of knowledge of this particular coding scheme. I've used nine other languages in my total career but have not used C# or Code Labs before. However, I did find that Irfanview has a numeric readout in the histogram feature that will do exactly what I need. I just ran the test on a Panasonic FZ50 camera and got some very confusing results in RAW versus JPG. The later behaves as expected versus ISO but the former is nearly flat above ISO 100. My measuring problem is solved but now I have a camera phenomena to tackle.
Thank you all for your time and effort to help me in this endeavor.
