Photo Batch is a program for Mac computers that comes in handy whenever you wish to edit, rename or rotate a large amount of pictures at the same time. This application might prove to be of good use if you wish to prepare images for a slideshow, screensaver or photo collage in such way they meet the same specifications.
You can work with this image tool to adjust the levels of brightness, contrast, and saturation, crop photos, and rotate pictures at any desired angle. Furthermore, you can batch rename dozens of images using the preferred output settings (append suffix to the new name, enter new name, etc.).
I also liked that the application can be used as an image converter. All you need to do is to select the input files, choose the proper output format and destination folder, and the program immediately processes the photos.
The only aspect I don't like about this photo editor is the fact that it works with a small amount of image formats (JPG, PNG, and TIFF). Hence, you can't process files with extensions like PSD, DNG, BMP, etc.; though, you can use Preview app to export images of the aforementioned unsupported formats to JPG, PNG, and TIFF.
All in all, this program offers quality results and comes with a straightforward interface. What's more, Photo Batch comes with a very reasonable price. As a conclusion, I'd say it's worth trying this image manipulation tool.
