   * If a stack is preprocessed as HDR, combining multiple camera frames to produce HDR source frames that are then fed to Zerene Stacker, then the HDR process often produces outputs that are slightly different sizes. This happens because of the HDR process's own alignment procedure, combined with image noise or slight jitter in the stack acquisition.  In this case the best fix is to set Options > Preferences > Preprocessing > "Image Pre-cropping" to be the size of the smallest image produced by the HDR process.  Often this will be the same size as the original camera images, but with some HDR software it may be smaller.   * If a stack is preprocessed as HDR, combining multiple camera frames to produce HDR source frames that are then fed to Zerene Stacker, then the HDR process often produces outputs that are slightly different sizes.

-  * If a stack is shot as raw, then very rarely, some raw conversion software will make slight changes in the image size apparently at random.  Again, a good fix is to set Options > Preferences > Preprocessing > "Image Pre-cropping" to be the size of the smallest image produced by raw conversion.+  * If a stack is shot as raw, then very rarely, some raw conversion software will make slight changes in the image size apparently at random.  Again, a good fix is to set Options > Preferences > Preprocessing > "Image Pre-cropping" to be the size of the smallest image produced by raw conversion.  As an alternative, try turning off distortion correction in your raw converter.  Lens distortion can change with focus, prompting the raw converter to output slightly different image sizes.
