How I take photographs has changed in the digital age. With film and SLR, each shot had to be composed carefully (film was expensive), lighting and exposure had to be just so before clicking the shutter. 20 years of film photography netted me about 5,000 decent, memorable photos.
The digital age changed all that. No film. No processing. No printing. Most of the time my camera is set to point and shoot and that’s exactly what I do. Shoot. And shoot again. 10 years of digital photography have netted me about 15,000 photos.
Here’s the problem with all those photos. Duplicates. iPhoto has plenty of photos that are mostly the same shot; perhaps a variance in exposure or lighting or something, but if it looks like a dupe, feels like a dupe, it’s a dupe and that wastes space.
How do you get rid of duplicate photos in iPhoto (or Apple’s Aperture, or Adobe’s Lightroom)?
There’s an app for that.
PhotoSweeper Lite is an inexpensive Mac app that finds photos with similar content. It doesn’t care about metadata or other tricks. It checks the photos and gives you a visual grid list of what it thinks are duplicates.
Load up the photos and PhotoSweeper begins comparing each one.
Once PhotoSweeper has swept its way through your photo collection, it’s time to display the results and give you options to keep or reject.
The attractive grid layout makes it a simple process to see which photos are similar to other photos.
For a few dollars more there’s a full version of PhotoSweeper which uses six different comparison methods, even if photos have been altered, edited, or enhanced, or even if the photo has different sizes.
If you like the Lite version, you’re likely to really prefer the slightly more expensive version as it manages photos in groups and can bulk rename photos while you’re copying or moving.
This is the kind of photo tool you won’t use every day (unless you take a huge number of photos), but it’s also a good way to help clean up some of the clutter in iPhoto.
