Info

Imatest Documentation Read images dialog box, showing a batch of 6 files (form f/5.6 to f/32) Use the View/Rename files module to change the meaningless names generated by the camera to more meaningful names that contain key EXIF data such as the aperture, focal length, etc. The file names in the above illustration were processed through View/Rename files. SFR can also be used to generate input for Batchview, especially with targets that contain slanted-edges near the center, part-way out, and near the corners. The composite target shown below works quite nicely and also includes the Log F-Contrast and Star charts. Sharpness target (30x40 inch) for cameras up to about 16 megapixels. Details in The Imatest Test Lab. Instructions for running SFR with this chart can be found in Using SFR Part 2. The sections on Repeated runs, Multiple ROI fine adjustment, and Automatic ROI refinement contain some helpful tips. 228 of 451
Imatest Documentation Running Batchview To run Batchview, click the Batchview button in the Imatest main window. Initially, a blank screen will appear. In succeeding runs, saved file names will be read in, and a display will appear on the screen. Empty Batchview opening screen Enter the batch summary file(s), whose names have the form rootname_chan_sfrbatch.csv, into one of more of the file name windows (A, B, C, or D) at the bottom of the Batchview window. Rootname is typically the root name of the first file in the batch (the file name omitting the extension). Chan is the channel: Y (luminance), R, G, or B. When files have been entered into the file name window(s) corresponding to the Display menu (lower right), the results will appear. Here is an example showing results for A and B in Imatest Studio. A large number of display options are available. Batchview results with two displays (Imatest Studio) 229 of 451
