P: Support cataloging PNG files in Lightroom

I've spotted the problem... you're using a different program called Lightshop! Sorry, just kidding. 😉 It's been a long day!

I do understand your frustration. PNG isn't a format suited to photographs, so I'm not sure you'll get any joy on that one, however the request is at least here for voting.

Did you realise that your PSD files can be imported into Lightroom - you just have to resave them with the maximize compatibility turned on. That is a process that could be batch processed, which may help a little.

Lightroom is primarily targeted at processing raw images from dSLRs. There are no dSLRs that produce either image type.

That said, LR does support PSDs assuming they are saved with maximum compatibility. This is required because, without it, LR would basically have to have all of PS's rendering engine embedded to process all those layers into a usable image, and that would make it enormous.

It also partially supports PNGs in certain areas of the program, just not for cataloging.
