Info

Imatest Documentation Batchview display from one set of tests: Canon 17-85mm, 26mm focal length Two small plots (SMIA TV Distortion and Chromatic aberration area in %) and some EXIF data (metadata) from the first file in the batch are displayed on the right. Preparing to run Batchview The first step is to acquire one or more groups of test chart images. By a group we mean a sequence of images in which one parameter is varied (most often aperture, i.e., f-stop, but focal length, ISO speed, etc., could also be varied), usually with other parameters fixed. The chart can be one of the composite charts illustrated in The Imatest Test Lab, but the most convenient and consistent results are obtained with the SFRplus chart, shown below inside the SFRplus setup window in Rescharts, which must be run to save settings prior to doing a batch run for several files in (the automatic, non-interactive version of) SFRplus. 226 of 451
Imatest Documentation Rescharts SFRplus window showing settings used for the above Batchview run: 9 regions (1 center, 4 part-way, 4 corners) SFRplus: The following settings are recommended when you run SFRplus in Rescharts. (Full instructions for running Rescharts can be found here). Select 9 regions (Center, corners, part-way) for optimum results. Chart contrast (typically 10 for SFRplus charts) should be entered. It may be used to calculate the camera gamma used to linearize the image for analysis (the results do not depend strongly on gamma). Vertical edges are recommended because they generate better chromatic aberration measurements-- they're close to tangential. Open the SFRplus Settings & options window to view settings. Most have no direct effect on Batchview. We recommend checking Close figures after save. The input file to Batchview is always saved for batch runs. When the settings are correct, click Save settings to save the settings without running SFRplus or click OK to save settings and interactively run the selected file. Then press SFRplus in the Imatest main window and select the batch of files to analyze. A maximum batch size of six is allowed in Imatest Studio. 227 of 451
