A lot of processing RAW depends on what camera and propriatory file format --- example, Nikon is .nef and Canon is .crw or cr2. AND what lens you are using.
We take Canon .cr2. We use Sigma 8mm EX.
Our work flow is to transfer the .cr2 images to a hard drive. Then use Photoshop CS2 to open 4 images in Adobe Camera Raw Converter 3.3. (ACR)
With PSCS and Elements 3 you can only open 1 Raw file at a time, but can load and apply the same settings to next 3 images.
In ACR for Sigma 8 lens
Apply the same white balance [example color temperature 5000] to ALL 4 images.
Set ACR to output 16bit, RGB 1998 (more vivid colors) rather than sRGB. When using Panoweaver use only 8bit.
On the Lens tab -
Set the Chromatic Abberation Red to -40. This brings the red channel into line with the Blue and Green channel. The out of alignment RED channel causes some fuzzyness. The affect is to sharpen the image.
You can also change the green channel.
The Sigma 8 has some light fall off (darkened vignetting) around the lens rim edge. Set the Vignetting slider to +100% to remove the vignetting. Set the Mid slider to about -12. This balances the exposure full width of lens glass.
Make sure you apply these settings to ALL 4 of your images.
You might want to save them as 8bit to be stitched in Panoweaver. PW4 does not work withe 16bit files yet. Sometimes I save the files out to 16bit TIFFs with a new filename incremented 1,2,3,4.
When I think of more, I will update this comment.
