Exif Data Missing (Black Levels)

Post by benjimeltzer »

We would like to use xnconvert/xnresize to decrease the size of some multispectral images but we have run into some trouble with certain exif tags.

In particular the "Black levels" tag is missing from the output.

This tag is needed to calibrate brightness of multispectral data from the Micasense camera. Do you know why this could be?

Any help would be appreciated.

Sample files before and after conversion can be found here: https://drive.google.com/drive/folders/ ... sp=sharing.
