I have some work in progress here: http://echophoto.dnsalias.net/ekr/index.php/photoarticles/59-sony-alpha-900-vs-67-analogue-round-2?start=1
It's about Ektar vs digital. My first measurement on Ektar 100 gave around 12 stops, but I have just reshot the Stouffer wedge I use. It's very close to my Sony Alpha 900 DSLR shot under identical conditions but I may need look more into scanning. In 2-3 weeks I will probably have drum scans also. This kind of testing takes a lot of time, turnaround time for film development here is about a week. So I first expose, wait a week for development, do my own scanning and send some samples to Berlin, German, for drum scans.
It seems that most authors find better DR values than what I have measured. So I refine my measurements.
Dominique Ventzke has been very forthcoming on helping with drum scans and good comments. He has a scanning service at: http://www.high-end-scans.de/
I am just curious if the DR of films has been measured and posted anywhere. I have been shooting with Portra 160nc and i am somewhat blown away with the amount of dark and highlight detail that gets recorded.
Anyone else noticed it. I scan 48bit dng on a Coolscan 8000, the negs I am shooting are with a Rolleiflex T.
