The Digital Photographer's Software Guide
Comments
One of the great benefits of digital photography is the relative ease with which geometrical
distortion can be corrected by software. To do this, the characteristics of the
individual lens must be known, which is why Acolens provides its analysis tools. For
interior, architectural, and product photographers, such a toolkit is highly desirable.
Acolens is a professional solution that is both optically sound and easy to use. At its
launch, it won the “Photokina Star—Highlight of Photokina 2006” award from
German photography magazines digit! and Photo Presse.

DxO Analyzer
Vendor: DxO Labs
Purpose: Professional test package to check the image quality of any image capture device
Description
DxO Analyzer is a unique software tool that uses advanced mathematics to measure key
properties and optical faults in all kinds of image capture devices, including DSLRs.
Used by journalists, magazines, and camera manufacturers, it produces a mass of data
from a relatively simple test target on which is a matrix of small black dots.
Using DxO Analyzer is a two-step process. First, the tester shoots the target under controlled
conditions, using a reference DSLR fitted with the particular lens being tested.
Several shots are taken at each combination of aperture and focal length. Focus error is
eliminated by micro-bracketing between groups of shots.
In the second stage, DxO Analyzer examines the results, looking for tiny variations of
position and shape among the dots in the matrix. It measures sharpness with exceptional
precision and—here is the key point—how it varies across the frame.
There are two editions of the product. The Camera Edition evaluates overall camera
performance, and the Component Edition takes a broader range of measurements using
RAW data, so that you can differentiate between various components such as optics,
sensor, or image signal processing. It complies with all major ISO and industry standards,
such as SMIA, MIPC, and I3A.
