Note on File Format
When saving images (using Save
or Save As in the File menu), you
have a choice of file formats. The
default produces .fit files, but .tif,
.jpg, .png, and .bmp file formats
can also be selected. Having a
choice of output file formats is
useful, especially if images will be	Figure 21. The Batch Process window

than .fit, you will need to check
the Auto Stretch box, or other-
wise Stretch the image to change

the Output Range (in the Stretch command window) to match the Size Format (in the Save As window). Otherwise, the Output Range will likely exceed the Size Format, and the saved image will be ruined (will turn all white).

For example, say the Output Range is set to create image brightness values in 16-bit format, while the Size Format of a specific file format (.jpg, for example) may only support 8-bits. Since the 16-bit format sees 65535 brightness levels, and the 8-bit format can only support 255 levels, all of the levels above 255 in the 16-bit image (i.e. the vast majority of the 16-bit brightness levels) will be saved at the maximum 8-bit value of 255. So the saved .jpg will have very little brightness information from levels 1 to 254 and almost all the brightness information at level 255. Thus a white image results.

If you plan to do all image processing within MaxIm DL Essentials Edition (or the optional full version of MaxIm DL), saving images in the FITS (.fit) File Format using the IEEE Float Size Format is recommended. This ensures that all saved data will be kept intact. If another Size Format is utilized, there may be some loss of data, especially when saving combined images.

Batch Process

Batch Process can be used to process multiple images simultaneously using the various commands available in MaxIm DL Essentials Edition. It is espe- cially useful when calibrating and converting each raw image to color. Select Batch Process from the Process menu (Figure 21).
