PhotoShine is a free program that will let you apply funny, pretty and eye-catching effects to your favorite photos.
PhotoShine's biggest problem is its interface, which is hard to navigate, doesn't resize properly, and just looks a old-fashioned. Improvements here would make the app much, much better. If you can get past this, though, PhotoShine is packed with loads of features, frames and scenarios that will allow you to personalize your photos for almost any occasion you can imagine.
To use PhotoShine, just hit the green folder icon and you can open your photos. Once they're in, you can re-orient, resize and move them, as well as applying some color effects, like gray, old and sketch. Some of PhotoShine's effects are better than others, though, so check them all out before saving.
Where PhotoShine really stands out, however, is in its effects, frames and other features. There are bunches of them for you to play with, organized into strange-sounding categories called things like Baby, Simulation and Magazine. The great thing about PhotoShine, is that simply clicking on the effect is enough to insert your image very accurately - it detects people and faces very well, and even if it doesn't, you can change them by double-clicking again.
PhotoShine's effects are certainly not to everyone's taste, but if you're looking for some fun for your photos, it's worth checking out.
