OptimumCS-Pro, a very useful iPhone App.

Keen on creating that killer landscape photograph? Among other things, it’ll need to be sharp, very sharp; probably over a huge depth of field.

Achieving that hasn’t been easy, even for accomplished professionals, who know they can’t depend on depth of field scales for the very best results. That’s why they habitually stop down a wee bit further than the “recommended” aperture, hoping for extra sharpness. But will they, instead, end up with too much diffraction? It’s all a bit hit and miss.

Now, with OptimumCS-Pro, everything changes. Input three quantities: focal length and the distances to the nearest and furthest object that need to be sharp in your image. OptimumCS-Pro calculates the focus distance and aperture that minimize the blurring caused by the combined effects of defocus (the fact that objects are not at the focus distance) and diffraction, resulting in the sharpest possible image the laws of optics will allow. This approach is unique and now represents best practice in working with depth of field in landscape photography.

This innovative and highly advanced image sharpness calculating tool is available as an iPhone app. For more info, visit the site and the App Store.
