There are just too many things that don't work in the Windows version. I'm using the most recent version 6.0.0 and many dialogs/fields just don't do anything when you click them. (Yes, even in the metadata editor.) Even things that did work in the Beta do not work now.

They claim that it handles Audio and Video files. What they really mean is that it will show a thumbnail and play them. You can't edit any of the metadata for these file types other than internal digiKam things like tags. But it won't write those tags out to either the file's metadata or an external .XMP file. So the work you do in digiKam is only available in digiKam, and if its database gets corrupted, you are screwed.

I got this because it supported AVIF and other modern formats, however it did not render the HDR AVIFs I had properly. But that's simply disappointing and a waste of my time. What was infuriating was that I opted for the machine learning face-detection etc. features, which said it'd be about ~2-3 gigs. Then 9 gigs vanished from my free space, and I got hardly any of it back after uninstalling, *and it didn't even delete the ML stuff* (~900mb) or however else it stole that space, and gave ZERO options on what to remove other than the program, like whether to leave database files, etc. for a reinstall.

~~I still don't know where the space went. ~~ I FOUND IT. This program has horribly confused (and confusing, but I mean the program itself is confused) regarding what an "Album" is, and what a Folder/directory is. I tried to add a Folder to the library. It was a screenshots folder on another drive. It gave me errors saying a file/folder exists with the same name already. (Okay, User/Pictures has a "screenshots" folder by default... but why TF would that be relevant if I'm trying to create a separate ALBUM?) Can you even create an actual other ALBUM? Who knows. So I renamed the folder to "Game Screenshots"; sure, whatever.

What did it do? IT &&%$**# COPIED that folder into my User documentsPictures folder!!! What is the point of a photos program that has a database if it just copies everything without comment into your Windows UserPictures directory?!

And, yeah, it still never automatically cleaned up its ~900mb of files (to say nothing of how much extra that would have been had I added a terabyte of pictures and its database grew to whatever size, assuming it wouldn't have tried to copy everything if it was on on the same drive.)

Absolutely ridiculous. This kind of thing is what gives OSS a terrible reputation.

Almost perfect. Does everything, what a photo organizer has to do. And it's free.

It has a steep learning curve at the beginning, though there is a lot of documentation around to start and easy ramp up.

There must be some advantages to this app but I simply can't find any in this muddled mass of windows that don't make much sense individually or collectively. Spent a day with it and then jettisoned it from my drive and washed my hands thoroughly. If this was my only alternative to LR, I'd gladly pay my annual fee to Adobe.

Pretty good both in usability and interface. It has the same UI features and organisation ways that you can see in other very popular open source software (Blender, Krita, and so on...), many options in making your personal workflow and layout, pretty good performance and some extra sweets for those who is interesting in advance organisation features (face search, similar images and even more). I think you certainly should give this program a chance and make your very own opinion because UI is kinda unusual for a newcomers that never used Open Source software.
