For years I've been using Apple's Aperture professional photo editing app. I really liked it because it was easy to use and worked well. There were also a couple of HDR plug-ins that worked really well with it. Back in 2015, Apple decided to "kill" it. Meaning they wouldn't support it anymore. They announced that if you upgraded operating systems above 10.14.6 Mojave, the app wouldn't work anymore. So, for years I haven't upgraded my operating system, mainly because the way photos are stored on Aperture is proprietary to Aperture (which is the one thing that I intensely hated about it). Photos stored in the Aperture are not accessible except when opened through Aperture. Well, it's now been long enough that I have other apps (such as MS Word) that are saying I need to upgrade, but I need a newer operating system than 10.14.6 Mojave to do it. So, I bought a 1 gig external solid-state drive, and for the past couple of weeks, I've been opening up my Aperture photo files and exporting them to files on the SS drive. That's the only way to get them as jpegs that any photo program should be able to use. There were thousands upon thousands of photos, so it's taken a while, but I'm almost done. So, my question is for those of you who like to use photo editing apps: which one do you use, and why do you like it? If you've ever used Aperture, is what you're using similar, or is it a completely different system I'll have to learn to use? I'd appreciate any input as I'll obviously need a new photo editing app when I upgrade my IOS, and Aperture quits working. Thanks in advance.
