If you're looking for something that does photo enhancements and corrections like Lightroom, check out Polarr. It runs entirely in the browser but also has installable versions as well for Mac and PC. It's a photo editor, not a photo repository, so it's not really designed for storing all your photos. But as a photo editor it's very powerful. There's a free and paid version. From memory the paid version is a one time charge and very reasonable.
I've just been talking about Polarr in the
Mini 2 area.
After years of using Affinity Photo I ended up subscribing to the Lightroom/Photoshop package shortly after getting my
Mini 2. I'd never used DNG files before so after I was made aware of lens profiles and distortion I started exploring this space a bit and found here's some issues with the free/cheap apps when it comes to DNG files (primarily MacOS but I've added in Windows info where I've been able to test):
Affinity Photo:
Has 2 RAW engines on MacOS. The 'Serif Labs' RAW engine relies on an open source lens database called Lensfun which has only a couple of DJI lens profiles in it, none of which are for the
Mini 2. I imagine a lot of the DJI range is currently missing at this point in time.
In this mode the in-built lens profile in the DNG file will be ignored and the developed picture will have lens distortion and some vignetting. This mode does however clean-up hot pixels.
The other engine is the 'Apple Core Image RAW' engine. This mode does use the in-built lens profile so the developed file looks great and distortion free. What it doesn't do is clean-up hot pixels so dark/night photos are covered in red/green pixels and unusable without manually cleaning it up.
I don't have the Windows version but I believe it only has the Serif Labs RAW engine
Darktable:
Uses the same Lensfun database as Affinity Photo so pictures processed with this have lens distortion.
Polarr:
Web version loads up and exports the embedded DNG preview image (960x720) so is unusable (please correct me if I'm doing something wrong here).
MacOS version: Loads up the DNG file fine but appears to use the Apple RAW engine, and therefore the profile in the DNG, so lens distortion is fixed but hot pixels aren't removed so not usable for dark/night photos.
Windows version: does a decent job with lens distortion, so I assume it's using the inbuilt profile. As per the MacOS version it doesn't clean up hot pixels.
Lightroom & Photoshop use the inbuilt lens profile and clean up hot pixels brilliantly. I could have persevered with Affinity Photo but even a photo I took indoors with OK light had one or two hot pixels, hence why I ended up reluctantly paying the subscription fee to Adobe.
