I know film testing is very personal, but I want to compare notes with any of you who may have been used the same film/developer combination. In the past I've screwed up this test so badly, so I want to make sure I've done it right.
- I am testing Delta 100 (4x5) with Ilfotec DD-X.
- I kept the temperature at 68F.
- I used the development times suggested by the Ilford tech sheet for this film which was 12 minutes intermittent agitation.
- I used the nikor tanks to develop the sheets.
- I used the Ansel Adams method as it appears on The Negative (using third stops--my lens indicates these third stops)
- I left the shutter speed constant and changed the f stops.
My results showed that my personal EI for this combination is 160.
Are my results comparable with those some of you may have had?
Thanks.
