One of my projects for 2017 is to go through my 300+ GB of family photos and cull them. There are plenty of moments where I might snap five shots of the same thing, but I often fail to go back through to delete the bad ones. I mentioned this problem on Twitter, and @katiefloyd recommended PhotoSweeper X:
@bradleychambers Used PhotoSweeper for this and was pretty happy.— Katie Floyd (@KatieFloyd) December 25, 2016
PhotoSweeper is a tool to eliminate similar or duplicate photos even in photo collections. It works with photos from Apple Photos, iPhoto, Aperture and Adobe Lightroom libraries as well as photos from your hard drive.
I used the demo for about ten minutes before I knew this was the app for me. In just under 90 minutes, I went through ALL of my 2016 photos. It allows you to sort photos taken within a few minutes of each other, easily compare them, and delete the old ones.
