I have so far rarely shot to the raw output, and I am not very familiar with the tools in that area.
From time to time I am interested in examining the data in a raw output file (Canon .CR2, mostly), perhaps to see the values at individual photosites but also to see the distribution as a histogram (and I guess I would really want to see it in a histogram "by channel").
Can anybody recommend a good software tool for this? It might even be something I have, and don't know it.
Some while ago I did some of this with Canon's DPP. In the version I had at the time, the raw histogram display could have its horizontal axis set to work in "raw units" (0-4095), but that seemed to disappear in the next version. Now, it seems to be in an arbitrary scale in "stops", and I don't know what the origin is or even the values at the ends.
Thanks for any help.
