AlienSkin Exposure X3 VS JPEGView

There are non-subscription alternatives, though they differ from lightroom. I quite like Exposure[0] and although I haven't used the desktop version of RAW Power[1] its ipad app is quite good. [0] https://exposure.software. - Source: Hacker News / 9 months ago

Although I have a Fujifilm x-t200 with the kit lens, I take most photos with my Apple 12 pro max. It does an outstanding job. But I use Lightroom and Photoshop to color correct, straighten, and crop and sometimes run it through Exposure's filters to make it look a little richer. Source: 11 months ago

I really like Exposure 7 as a Lightroom replacement. Super fast and really competent raw development. https://exposure.software. Source: over 2 years ago
