LCC: Calibrating lenses in Capture One
Problem
How do I calibrate a lens if I am experiencing problems with lens cast?
Solution
Perform a Lens Cast Calibration. Lens cast is a result of the sensor being exposed to light from a very sharp angle and will typically occur as a green cast in one corner of the image, stretching into a magenta cast in the opposite corner. Capture One's LCC tool can correct towards uniform light...

Lens Choice for Digital Backs on Technical Cameras
Problem
Not all lenses work well with all digital back. Some backs may show vignetting, artifacts or lines with certain wide angle lenses.
Solution
Summary It is important to use lenses that produce a wide enough image circle to accomodate the back's CCD and/or CMOS sensor. In-Depth     Example::  Lenses with 70 mm image circle: (will barely cover the area of P 65+/IQ160/IQ180 and not allow for any shift) Lenses with 60 mm Image circle (w...

How to use Lens Calibration on Leaf backs
Problem
Shooting images with wide angle lenses and exploiting large format camera movements often results in lens fall-off and color cast effects. Another effect is the so-called centerfold effect where lines may appear in the image.
Solution
Lens Calibration corrects all three of these effects.   The following shots show the same image with and without lens calibration:     What is lens cast and how is it recognized?   Why is Lens falloff associated with lens cast?   Lens cast results when light from the lens strikes the digital senso...

How does the image size of the sensor in digital backs effect image angle of view?
Problem
The sensor in some Phase One backs is smaller than the medium format film that lens angle of views calculations have traditionally been based on. Also known as lens conversion or magnification factor.
Solution
Summary To calculate the digital angle of view simply multiply the medium format film focal length by the Lens factor resulting in the approximate digital angle of view.  For example,  I am shooting on a 645 camera with the H20 and a 105mm lens, my digital angle of view will be approximately (1.3 x ...
