Question about Maximizing Compatibility option. Trying to import PSDs into Lightroom.

[hillaryk44528040]

Hello! I am trying to import PSDs from Photoshop into Lightroom without losing quality. I just found out about the Maximizing Compatilibity option and now I have my Photoshop preferences saved so that any new PSDs will be saved at Maximum Compatibility. However, I am unsure whether or not all of my old PSDs were saved at Maximum Compatibility or not. My question is: Is there a way to figure out if an existing PSD was saved at Maximum Compatibility? 

Thank you!

If you can't import it into the Lightroom catalog, max compatibility was not on.

Maximum compatibility inserts a flattened composite layer into the file. This flattened composite is what Lightroom works with. It has no layer support whatsoever and can't read PSD layers.

Great, thank you! 🙂

If you're technically inclined you can use exiftool:

exiftool <file> | grep "Merged Data"
