Cityscape and architecture with the IQ3 100MP Achromatic

The IQ3 100MP Achromatic

The new IQ3 100MP Achromatic Digital Back is built upon the IQ3 platform and is a project I had looked forward to for quite some time. Built with a newly designed, dedicated sensor that removes the Bayer Color Filter, while retaining all the versatility and functionality of the IQ3 100MP, its promise had me anxiously awaiting the day when I could put the detail and quality to the test. That day finally came in mid-April and I’m happy to be able to share the results with you now. The IQ3 100MP Achromatic in use Designing a back that focuses only on Black and White photography can be challenging and to say I was impressed with the final results is an understatement. Black and white photography is something unique. With all the work and testing I do with our color systems, the specialized applications and benefits of an Achromatic back were a welcome challenge. By focusing on the detail render and functionality features, we are able to produce images that speak to what is at the …

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 …
