Backscatter Xterminator Editing Tool Launches

RC Astro and Go Ask Erin are thrilled to unveil Backscatter Xterminator (BSXT), a game-changing Photoshop plugin that eliminates backscatter from underwater photos with a single miraculous click.

A breakthrough for underwater photographers

Backscatter, the colloquial term for particulate matter suspended in water, has long been the bane of underwater photographers. Although many editing techniques exist to get rid of goo in underwater photos, nothing comes within light years of BSXT’s superpowers.

Retouching Underwater Images

It should not happen but sometimes it does anyway: those annoying little white dots in our underwater images, which detract from the overall impression of the photograph. Known as backscatter, these dots appear when small particles in the water reflect the light from a strobe. The more directly the strobe light hits a subject, the higher the risk of backscatter. That is why a strobe should not be pointed straight at a subject.

In this series of articles on postproduction of underwater images, we have worked a lot on white balance settings, basic and advanced exposure corrections, contrast and curves, advanced techniques of removing colour casts, basic and advanced retouching, final colour boost, cropping and sharpening. Finally, our image is ready! And now, we arrive at the question: What do I do with it?
