Washed out subs (LP). Dirty optics. No flats to correct all the dust spots. No dithering. Terrible noise. I salvaged the night with (very) heavy handed processing :-)
The result is very blue and very "wrong". But so far, it pleases my sore eyes after looking at heaps of noise... But then... Maybe I should realign the histogram :-))))
