b.d.trabitz___ Posted July 15, 2003 Share Posted July 15, 2003 Does anyone have any experiance developing 4x5 Fuji Acros. I would appreciate advice regarding time, temp, and agitation. I could use help in selecting a starting point for my own testing. I have D76 and HC110 on hand. The usual reference sources do not have information for sheet film only 35mm and 120 Link to comment Share on other sites More sharing options...
kunihiko Posted July 15, 2003 Share Posted July 15, 2003 I don't shoot 4x5 so I haven't experianced but <A href="http://www.fujifilm.co.jp/bw/img/ds_ti_pdf/163ai094c.pdf" target="_blank">Fuji's data sheet(Japanese)</A> says..<BR> EI100, with D-76, 7min30sec, 20C, continuous agitation.<BR> Link to comment Share on other sites More sharing options...
john_hicks___ Posted July 15, 2003 Share Posted July 15, 2003 I've used the same development specs as for the rollfilms (and I believe they're all the same emulsion) and the sheets were as expected. The only caveat imho is that the "real" speed is about half the ISO rating. Link to comment Share on other sites More sharing options...
tim obrien Posted July 16, 2003 Share Posted July 16, 2003 John. Your E.I. is one half the ISO rating. The real film speed is the ISO rating. Those tests are conducted in controlled conditions with every film under the same specs. They actually measure what amount of exposure will give you a certain density level on the film. Your results may vary because of metering technique, meter variance, shutter speed inconsistancies, and only about a thousand or more other variations. I usually shoot Acros @ an E.I. of 80 and am pleased with the shadow detail my Speed Graphic gives me. tim in san jose Link to comment Share on other sites More sharing options...
