6. Exporting to Other Image Processing Programs - If you have a
favorite image processing program like PhotoShop that you would rather
use to process and combine the RGB frames into a color image, then simply
save the extracted R,G, and B images in a format of your choice such as
TIFF or FITS and use any other image processing program to manipulate
and combine the images. It is recommended however that you keep your
original data file in SBIG format in the event that some step along the way
results in an irreversible change to your image file(s) that is not to your
liking. You can always extract the raw RGB channels again from the
original.
Special CCDOPS Functions for Single Shot Color Cameras
Filter Routines Specific to Single Shot Color Images
The raw images (monochrome, prior to conversion to color) from Single
Shot Color cameras like the ST-2000XCM require special handling when it
comes to filtering the images so that
you don't co-mingle the color data in
the filtering process. CCDOps has
enhanced filtering routines in the
Smooth, Sharpen, Column/Row
Repair, Kill Warm Pixels and
Remove Cool Pixels commands from
the Filter sub-menu of the Utility menu. As shown in the dialog below,
these commands allow you to check a Single Shot Color Image checkbox
that applies those enhancements to Single Shot Color images.
Track & Accumulate Single Shot Color Cameras
You didn't used to be able to do this and many people don't realize that
now you can use SBIG patented Track and Accumulate with Single Shot
Color (SSC) cameras like the ST-i. CCDOps has been updated to recognize
SSC cameras and Track and Accumulate will then make sure it co-aligns
images correctly, taking into account the Bayer filter arrangement.
