Measure the performance of cameras, lenses, scanners, and printers.
Imatest™ is the digital imaging industry's leading software package for measuring key image quality factors using inexpensive, widely-available targets.
Digital cameras, digital imaging systems, or scanned film: Measure device sharpness (MTF), perceptual sharpness (SQF), color response, noise, dynamic range, tonal response, lens flare (veiling glare), lens distortion, lens vignetting, sensor nonuniformity, and color moiré with SFR, Colorcheck, Multicharts, Stepchart, Distortion, Light Falloff (Uniformity), and Rescharts.
Printers: Measure tonal response, Dmax (the deepest printable black tone), color response, and color gamut with Print Test.
Does your camera measure up? Test its performance with Imatest.
A two-day Imatest training course will be held in Boulder, Colorado, July 10-11, 2008.

You can download an evaluation version that allows up to 20 runs of the individual modules. Online purchase and registration is available. Imatest comes in several versions:
Imatest Light, with everything an individual photographer needs to test cameras, lenses, and printers. $199 USD. You can always upgrade to Pro.
Imatest API, non-GUI executable programs that interface with automated test systems.
The price includes one year of updates. After one year you will need to renew your Imatest subscription to register the current version.
Imatest operates under Windows* 2000, 2003, XP, and Vista, and on Macintosh systems with Virtual PC 6 or 7. 512+ MB RAM is recommended. Minimum screen size is 1024x768. (*Often works, but not supported, on Windows 98SE and ME.)

Imatest news highlights Latest version: 2.7.2, March 22, 2008. Full descriptions of updates can be found in the Change Log.
March 16, 2006 Imatest 2.7 The new Dynamic Range module calculates dynamic range from Several Stepchart images of reflective targets (much easier than using transmission targets).
March 2, 2008. Imatest 2.6.11 The Screen Patterns module displays several patterns for Imatest modules, monitor calibration, and camera testing.
Jan. 6, 2008. Imatest 2.6 Two new options are available for refining multiple ROI selections in repeated SFR runs (Imatest Pro only). (1) Multi-ROI fine adjustment (shift, magnify, reduce), and (2) Automatic ROI refinement. These speed up test sequences of different cameras and lenses, where it may be difficult to maintain exact chart alignment.
Oct. 15, 2005. Imatest 2.5 supports the Siemens star chart. 144, 72, or 48 cycles analyzed in 8, 12, or 24 segments.
Sept. 4 , 2007. Imatest 2.4 Introducing Rescharts
a highly-interactive user interface for resolution-related measurements. Slanted-edge SFR is similar to SFR. Log Frequency measures MTF and color moiré from a chart that varies in spatial frequency. Log F-Contrast measures MTF over a range of frequencies and contrast levels, showing how much fine detail is lost as a result of software noise reduction. Third anniversary of Imatest's launch!
Imatest also produces Gamutvision: an ICC profile gamut viewer and much more. Visualize color gamuts, gamut mappings, and rendering intents. Evaluate ICC profile quality, analyze printer performance using downloaded profiles and scanned test prints, and see precisely how an image changes when printed.
