PicFx features several photographic styles that can be applied to photos, from black and white and sepia to other vintage and colored filters. Other than photo styles, PicFx includes a fair collection of items for easy and quick image enhancement, like textures overlays and frames. For obtaining different combinations, images can be filtered over as many times as you wish.
PicFx is a nice power-up for your photography, especially now that it comes for free.
Thanks a lot to ILAR for the news tip.
