Sigma Photo Pro is an image manager and manipulation tool for Sigma camera users who wish to organize their pictures, adjust the color balance of their images, and much more. This program can also be used to sort the photos within your Mac, view entire image folders as slideshows, and print pictures with little effort.
The app comes with a user-friendly interface and easy to configure editing tools. However, if you have any questions on how to manage this program, you can always use the built-in help guide.
An advantage of working with Sigma Photo Pro is that it brings you a batch renaming utility. This integrated tool helps you change the filename of your photos in just a few moments and organize your photo collections in an efficient manner.
A thing I don't like is that it supports only two output formats when it comes to converting images (JPEG and TIFF). Plus, the app lacks a picture resizing tool which might prove to be of great use at some point.
As for the rest, this application provides you with dozens of utilities for helping you efficiently organize and edit your photos. And since Sigma Photo Pro doesn't come with a price tag, I can't find any reason why you shouldn't give this app a try.
