uPhotos 

uPhotos is a small and very easy-to-use Mac application that allows you to change the color style of an image file in an instant. This simple piece of software can come in handy if you want to quickly modify any image that you might have stored on your computer but you don't want to install complicated graphic tools to help you out.

First of all, in order to modify the color style of any image file, you will have to load it. The uPhotos provides you with two modes in which you can do that. You can either provide the path of your picture or, a much faster way is with the help of a simple drag-and-drop process. Once you have done that, you can easily change the color style to black and white, cartoon, lollypop, memory or scan line with just a click of a mouse on one of the buttons located in the lower part of the window and, after you have reached the desired effect, simply save it in your system.

Other than that, the uPhotos comes with a simple and user-friendly interface and the lack of any settings and complicated menus keeps the job of modifying the color styles of a loaded image file as easy as a walk in the park.

To sum it all up, the uPhotos is a lightweight Mac application that allows you to instantly modify the color styles of any loaded image file. This simple program can prove to be a good addition to your graphical tools collection for your Mac system.
