Ilfochrome Re-Deux, Part 2
Those of you who have responded to my printing problem, I thank you, and I
took your advise. However, nothing has changed. I have persistent and extremely long printing times with this material - up to 140 seconds, and I cannot believe that this is "normal". I'm using the Beseler 45 Universal Light Source - 4x5 diffusion, and a Nikon N2.8 enlarger lense for 35mm work, enlarging to 8x10 with this paper. Processing is standard at 30 degrees for the Ilfobrom process, done on a Jobo CPP/Lift, using Ilfochrome chemestry - always fresh chemestry. The resulting print is characterized by a dark, dense image. There is a slight shift toward magenta. At 140 seconds exposure, the image finally begins to look normal. However, with these long exposures, I've had to make 5 exposures at 20 seconds each to avoid overheading the Beseler or buckling of the slide - non-glass carrier. I've asked before if this is normal, and I'm asking again: Are those printing times within what is considered "normal" for this process - I understand that the paper is 'slow'. Tanks again!! |

Some dumb questions: o Does the Universal head come with a 35mm mixing chamber? I have the impression it doesn't, but is there some adjustment or insert for 35mm work? Manual say anything? o What is the head-negative height set to? [adjustment normally used with the condenser head, scale on the right o Does this combination print OK when used with B&W materials? |

BTW sometimes the answer is just "I don't know" and rather than getting 150 responses with "I don't know" the group just remains silent. But here goes: I used a medium format Durst Enlarger with a 35mm mixing box when printing Cibachrome (see long time ago). My times were quite long as I recall, details vague, it was 30 years ago. Slides never buckled. So I guess I don't know. |

No, your printing times are way too long. It doesn't matter how many times you ask. The answer will be the same. When I print Ilfochrome my printing times are on the order of 20 seconds. These are the same as my black and white printing times. What is "Ilfobrom process", by the way? The chemistry I use says P3 on the box. Ilforchrome is really easy to use, and really easy to get right. Whatever the problem is, it doesn't sound like USENET can do anything about it. Do you have anybody local who can help you?.

No, it is not normal. My times are around 3 stops longer than Ilford Multigrade IV paper without filter which is around 20-40 seconds at f/8 for a 30x40cm (12x16"). Chemistry is either P-30 (no more made), P3.5 (5 liters, all liquid, replaces P-30), P-3 (larger quantities) or P3.X (large quantities, replenished). Note that the contrast of Ilfochrome paper is much lower than B/W or RA-4 negative paper as slides are very contrasty and though paper must be very soft to restore a normal contrast (but global slide+paper contrast may be too high). This means that when you adjust an exposure, you must use larger values than thos common in B/W: a half stop in B/W is a big difference, with Ilfochrome you easily change it by full stop values and when you're in the 40" range, a full stop more exposure is another 40" ... To avoid to overheat the film/slide, you should put a hot mirror filter between the enlarger's lamp and filters. You can buy such filters at a reasonable price at B&H (www.bhphotovideo.com), search with "Rosco hot mirror" For those wanting to replace their dichroïc filters, they also sell MCY or RGB filters.

Ilfochrome Re-Deux, Part 2
I do remember having similar long times with Ilfochromes perhaps 15
years ago. Part of it was due to the fact that I did not have the 35mm mixing chamber for my Beseler 45. That would have cut the times at least in half or perhaps even more. I only experienced this with 35mm slides. When I began using medium format exclusively, my times got shorter. I suspect that's a good part of your problem.
