    Re: Paper negatives

    I think so, I think that reciprocity failure is an intrinsic property of the chemistry of the silver chloride/bromide in films and printing papers.

    Wow, James, Iíve never used paper that I was able to rate at 100. The best I experienced was Galaxy Hyperspeed paper which I rated at 24 (but Galaxy seems to be long gone). Hope you enjoyed the articles. Iím still learning too

    Peter, in my exposures Iíve never added any additional time for reciprocity and the images have always come out fine. My longest exposure was a little over 60 minutes but I routinely shoot exposures 1 or more minutes long.

    A couple of test shots with my new 4x5 Graflex RB Series B (scanned and inverted in PS).

    Re: Paper negatives

    I might be wrong - However I set my spot-meter at 100 ASA (ISO) and made a few test images. The best one was at f-11 1/50th of a second and ISO= 100. I was very surprised at the outcome. I think that this paper INDUSTRX is the fastest that I have aquired - and Now I Want MORE.

    No paper will ever come close to ISO 100. That's just beyond the reach of a bromide emulsion.

    Thanks Don. Yes, I have shot 4 mins / 8 mins around sunset since with no problem.

    (Well the problem then becomes the reciprocity of the day, by 2/3rds through the exposure the EV had dropped by one and the exposure it should have had was exponentially longer )

    Old track by Peter Brooks

    Canham 5x7, TTH RVP at f8, pre-flashed Ilford Mutigrade IV Glossy at ISO 3. A 15 second exposure at sunrise. Scan, inverted in PS.

    I'm enjoying the 'top hat' style made possible by the slow paper speed. Bah! Who needs a shutter? (I do, most of the time...)
