Small issue with exposure compensation display

[John Tompkins]

In rtengine/imagedata.cc the line in the constructor for FramesData:

if (find_exif_tag("Exif.Image.ExposureBiasValue")) {

I believe should be:

if (find_exif_tag("Exif.Photo.ExposureBiasValue")) {

If I change that my Nikon D600 now shows the correct exposure compensation with the “Quick info” button where before it would show nothing. In other places in the code it does use “Photo” rather than “Image” so I think this is correct. Plus the EXIF tab shows it under “Photo”.

both tags might exist (see https://exiv2.org/tags.html). I agree that ART should check for both though, I’ll fix this. Thanks!

metadata: check for "Exif.Photo.ExposureBiasValue" in addition to "Exif.Image.ExposureBiasValue" for exposure compensation

Fixes #49
