I remember (in the past) some astrophotographers push processing Kodak Ektachrome 200 1 Stop. Other than the speed increase did it lower contrast a bit?
Should I push process the new Kodak Ektachrome 100 1 Stop as well? Longer exposure time at ISI 100 vs ISO 200 is not an issue,
I am usually a hypered negative astrophotographer. Limited experience in Positive films.
See www.darkstarImages.com for some examples of hypered negative long exposure images.
