How to check if DNG is lossy or not?

[jj59691772]

Hi, I've been converting to DNG, but recently starting to use lossy compression DNG for a lot of files. Now I have a mix of lossy and non-lossy DNG.

So, how can I check if DNG files are lossy or not, so I can lossy compress them to save space?

There seems to be a flag called "compression" in the EXIF metadata, that specifies the compression type, but there seems to be no way to search for this within lightroom.

The DNG metadata panel (select from the dropdown) shows Lossy Yes/No.

You can use the Filter bar to find all of your lossless uncompressed DNGs. Watch out for the below issue if you have DNGs with Heal Spot Removal applied. When converted to Lossy DNG files they they may appear in the Libary module as pink squares. Your system may or may not exhibit the issue. Just a warning!

Ah, I didn't relize it was under file type! Thanks!

I was looking for some sort of "dng" filter.
