PhotoTune

PhotoTune is a photo enhancement tool that can help you improve the quality of your images in a few simple steps.

The first thing to do is to select an image. Then, you will be asked whether you wish to adjust the dynamic range; that is the contrast of the image. In all the steps you will be shown both the original and an adjusted version and you can preview the changes as you apply them. You will notice a slider that you can move from less to more to adjust the contrast and the other features. To confirm that you are satisfied with the changes, click on the right image to continue with the next step or click 'Apply' to end the editing process completely. The next step is the Auto color, which automatically corrects the image color. The third step is the brightness correction, in which you must move the slider to adjust the photo's brightness to your liking and click the photo to proceed to the final step, which is Skintune. This one allows you to fine-tune the color, and should be only used if the image is a portrait. To close the program, simply click apply and save the resulting image to the desired location. Note that this is a demo, so it only shows a few options, not all of them.
In short, PhotoTune is a simple step by step wizard that will help you edit your photos in four steps.
