A successful first attempt, Bravo !
Love the inimitable rendering of the sky with the Pentax 6x7 and the Fujichrome film :

Hi all !
More
Easy &
Efficient than editing autosave.tif in L*a*b mode ?
I am now testing a new way to boost Pentax K5's performance at base ISO-80 :
- 8 RGB .PEF files stacked through DSS to a Color picture as usual
- 1/ these Raw files are exported one color plane at a time, each to a B&W .fits or .tiff file -or-
.. 2/ these Raw files are converted to B&W .fits / .tiff files (1/ to Super-Pixel 2/ to match Bilinear Color stack)
- the best B&W results from these are stacked
- result's levels are pushed to make a High Contrast B&W mask
- the Color picture and the High Contrast B&W mask are blended together in Elements, Gimp, Photoshop, etc.
- you can even try several ways to blend them together thus getting the best result to your taste...
Here is my 1st "
Pink prototype picture " using this process :
it is the Rosette Nebula from 8 .PEF files, each is a ~15 minutes long exposure...
... resulting in a Second place in DPR's Challenge named "Edited.." :
Rosette, Ngc-2237 nebula, 2nd place in "Edited" Challenge of DPReview

Now let's Compare this to the original picture, a simple stack from 6 .PEF files in 2015 :

... the 2 Raw files added to get the picture above are not the best !
And my 2nd "
Red prototype picture " using this new process :
= the Rosette Nebula from 7 .PEF files, each is a ~15 minutes long exposure...
blended in another way w/ its High Contrast mask

Which one do you prefer, the "
Pink" or the "
Red Rosette" ?
