PICOLAY is a free graphics utility that features the ability to perform various photo enhancements and permit you to create 3D holograms.

For all the uses included with PICOLAY, it remains lightweight, but the small size does not indicate its power. You can enhance your photos and generate MPO files (which allows for any number of JPG files to be saved in an MPO file, but the most common use is for stereoscopic images), GIFs, and slideshows, all derived via combined stacks of images.

Once launched, you are greeted with a simplistic interface consisting of three windows: one for the central functions - image list, stack operations, and options; the second is the selected image view; and the third is the image result. We noticed that some of the command windows, like the one for saving your work, were in German, but they were readily translatable - Nein = no, Ja = yes, for instance. It includes a manual, which is available on the author's website. And with so many features, it is a good idea to take a look.
