PhotoSweeper is a nice utility that lets you organize your pictures. It works with images loaded into your iPhoto, Aperture or Lightroom libraries or any photo that you drag into the application.
PhotoSweeper displays a pane with very comprehensive information about your pictures, which includes file name, document type, size, creation and modification dates, image size and DPI, orientation, exposure time, etc.
I like the fact that you can move a slider to change the matching level. If you move the slider all the way to the left more images will be shown, because even pictures that are slightly similar will be grouped. If you move it all the way to the right, only duplicates will be displayed.
Pros
- It works with three different libraries and photos on your Mac
- Adjustable similarity slider
- Good results
Cons
- It could use some on-screen instructions
I have used Graphic Convertor to do this for over 10 years. It has the facility also delete the oldest or the newest and one othe option.It really works. I once scanned 500,000 pics and yes it did take a while (I did have 32GB). Admittedly it is not straight forward to find the hidden gem but GC is so worth the money.
