How to compensate for lost sharpness at small apertures
The Lens Correction tool in Capture One Pro 10 has been improved and now also includes Lens Diffraction Compensation. This is a feature that compensates for the loss of sharpness and micro contrast that occurs in images shot using small apertures. Whenever you need a larger depth of field in your images, you can now stop down your lens at least one stop further than what you would previously have done without losing the perceived sharpness of your image. What is diffraction? Diffraction in a lens is not about how well the lens has been designed and manufactured, but it’s something that’s determined by the laws of physics. As light is an electromagnetic wave, it does not always travel in a straight line. When light waves pass near a barrier they tend to bend around the barrier and spread out. The aperture in a lens acts as a barrier. When light waves pass through a large physical aperture in a lens, hardly any bending of light will occur. But when stopping down the lens, some …
