Akvis Retoucher is a great way to remove dust, scratches, and watermarks from old photos. You can select and mask large areas to correct, or make finer corrections using features such as the Clone Stamp and Chameleon Tool, the latter of which is similar to Photoshop’s Pattern Stamp. Finding the perfect parameters can be hit and miss, but the results are good.
Using Photoshop to retouch the human face and body is a process that requires learning about the inner workings of channels, layers, masking, and many subtle techniques to get truly professional results. However, for iOS users, there’s a better solution for these particular tasks in the form of Facetune, a deceptively simple gem designed for fashion and beauty work that is capable of delivering some minor miracles with the utmost of ease.
