Camera rotation on the SCT had been selected so that a small crater
was following the horizontal limits of the CCD when making AD movements.
This is very important to minimize frame numbers.
There were 5 shots for each portion of the Moon.
I loaded all 640x480 images in PSP5.
I compared identical images at 1/2 size, 2 by 2 for quality and I eliminated
the worse one.
In each serie, I renamed the best ones according to their position :
TL, TC,TR
ML, MC,MR
BL,BC,BR
I opened a new large black background 24bits file for Top, Middle and
Bottom.
I glued in each the 3 portions xL, xC and xR (below TL, TC, TR)
The central image was cropped to 95% to eliminate borders artefacts and put
as top layer.
With tranparency at 50% the images are corelated.
Luminosity is adjusted in between the 3 images of a row, contrast is never
touched.
Again cropping at 95% to have a nice clean rectangular portion, saved
as greyscales with layers as H.psp, M.psp, B.psp
Vertical line cicatrisation is done with Iris or Prism.
A new large black background 24bits file is created where H, M & B as
layers are corelated as previously.
Luminosity is rechecked.
Horizontal line cicatrisation is done with Iris or Prism.
Image is reduced 37.5%.
