I use and recommend iPiccy.com for editing photographs.
When I have quiet moments, I often enjoy a little fun while experimenting with iPiccy, as a photo-editing tool.
The more I work with this application, the more I enjoy what it has to offer.
With the following photo of the California Coastline, I played with the “textures” and “lights” realms.
IPiccy provides a variety of selections when it comes to these, and it’s great fun to find those which work best with pictures you are editing.
And, it’s FREE!
