I use this program almost every day as a restored old photograph/coloured image shows so much more and adds depth to the image than the original. It definitely enhances the look of the website and book I am working on. It is easy to use. The support I received when there was a problem was adequate and friendly.

PhotoGlory is an excellent photo restoration program with an incredibly user-friendly workflow. It does an outstanding job of reviving old or damaged photos. I wish I had discovered PhotoGlory sooner, as it would have saved me a significant amount of money I wasted on inferior photo editing products.

I am in the process of digitizing 100 years of family photos, slides and film. Using Photoglory has been a great addition to my collection of photo management and editing software. All my scanners are supported as well as my preferred photo format.

I have many old family photos dating back to the 1920's. Most are B&W and it's very pleasing to see my relatives in colour. Some photos are in poor condition but this program restores them to a very respectable level. It is very easy to use and now I have had requests from others, who have seen the results, to help restore some of their's. Very impressive.

I have been using various photo software editing tools such as PhotoShop, Cyberlink Photo Directors, and others to enhance, update and repair software. This software delivers what it promised. I had several badly damaged photos, stains, scratches, tears, discolored pictures from several decades ago from slides, paper prints, polaroids that needed restoring. I used photoglory to restore the pictures to almost new, then used my other software to retouch and they came out looking fantastic.

I am passionate about old photos that I discover in my family and in old bazaars. This program allowed me to restore the former glory to photos taken 60 or even 80 years ago. The program is simple and intuitive. Thanks to him, the world of photography went back to the last century, bringing a smile to your face. I'm adding my 6th star to the 5 stars.
