I think this film (K-TP), amazingly, can do all this since its contrast range ("gamma") and maximum density ("Dmax") according to various developing processes can be adapted to virtually any value from a low range of gamma =0.6 (Dmax ~1.5) for regular B&W negs (intended for printing) up to a high gamma =3 (Dmax=4) for binary microfilm-kind images. This film can also be processed in reversal to yield direct B&W slides but this is not precisely documented in the Kodak brochure. The Ilford or Tetenal chemical reversal kit probably documents this (I did not find the info on the web yet). To get B&W slides from a regular B&W neg with K-TP film, here are some reasonable figures extracted from the manufacturers's literature available on their web-sites. Let's start from reasonable values for the final slide : AGFA Scala (standard process) yields a B&W slide with a gamma=1.4 and Dmax=2. Copying from a gamma=.7 (B&W regular neg), the intermediate film should in theory provide a gamma=2 (1.4/.7). This is typically the range of values obtained with K-TP processed with D76 (~=ID11). According to the Kodak brochure for K-TP, processing times in D76 from 6 min. (gamma=1.2, Dmax~2, ASA 64) to 10 min (gamma=2, Dmax~3, ASA 125) at 20 deg. C (68F) would be my choice for experiments. I would prefer for home precessing a single-use developer solution diluted 1+1, with a 50% increase processing time (assuming the same "+50%" rule as documented in ID11 process charts) to compensate for dilution, e.g. (1+1 /9 minutes/ASA 64/gamma 1.2) to (1+1 /15minutes/ASA 125/gamma 2). Now that I've found K-TP available in 120 rollfilms in Europe, I cannot do anything else but make a try soon... -- Emmanuel BIGLER ------------------------------ Date: Thu, 2 Nov 2000 08:46:24 -0500 (EST) From: Shane W Davis To: hasselblad@kelvin.net Subject: RE: Question about real need of a vacuum back... Message-ID: I have heard it claimed on the Contax G- mailing list that the optics for the G cameras are so good as to cancel out the advantage of larger negative size in the 6 x 6 case, at least where normal lenses (45mm for the G vs. 80mm for the MF camera) are concerned.

Message-ID: <20001102140223.25821.qmail@web3106.mail.yahoo.com> Ahhh, I don't quite buy that. Since I also have Contax G1 w 28mm, 45mm and 90mm, and am a subscribed member, the 80mm chrome will look better than one produced by the 45mm. The 45mm will look surprisingly good, as MTF charts attest. But hey, I love Contax equipment and own a ton of it, but against the Zeiss 80mm lens? I don't think anyone viewing the chromes would dispute bigger is better folks. The 45mm does hold it's own very respectedly, though. Blake Zeigler who is the US Contax Rep carries with him a display enlargment made with the 50/1.4 with representative negative contact print and a small super enlargement from a section of the 20 x 12 enlargement of the face of a building. The section enlarged is some stone sculpture on the front of the building facade. Needless to say, impressive. Enlargement made with a 40mm Zeiss Biogon enlarging lens, which isn't marketed in the USA. Anyone with $5,000 burning a hole in their pocket can contact Zeiss and get one on special order. That enlarging lens resolves over 900 lines/mm, exceeding the capability of what the film can capture. It is used in the photo-microcircuitry industry. --- Shane W Davis wrote: > I have heard it claimed on the Contax G- mailing > list that the optics for > the G cameras are so good as to cancel out the > advantage of larger > negative size in the 6 x 6 case, at least where > normal lenses (45mm for > the G vs. 80mm for the MF camera) are concerned.

Some experience in shooting both formats would show you that. Even "toy" medium format cameras as Brownies and cheap folders with fewer and uncoated optical elements deliver an image on medium format film. And that film produces an 11x14 or 16x20 print which has a richness and lack of grain the 35mm shot with a high end say Leica 90mm F2 Apo-Summicron-M ASPH will not have despite it's obvious resolution and contrast issues.

Obviously I have experience in both formats. I don't have experience shooting both in controlled conditions where the only controllable variable is the format. Different formats are associated with different uses; e.g., 35 mm is much more likely to be handheld than medium format. This is one reason to expect MF pictures to be more apt for big enlargements. > Even "toy" medium format cameras as Brownies and cheap folders with fewer and > uncoated optical elements deliver an image on medium format film.

I don't know what parameters guide comparisons of "richness" across formats. As for grain, I am sure that whoever made the claim had in mind an upper limit on enlargment size, because it seems clear that by making the enlargement big enough a difference could be brought out. It would still be interesting to see what the difference is given enlargement to 11 x 16 (this is as big as I ever go anyway). And I doubt by the way that most of the Contax G lens > are much better at all than optics for Nikon and Canon. mark rabiner I couldn't comment on that without talking out my butt, since I haven't made any careful comparison. I would think the comparisons would need to be with Nikon and Canon rangefinder optics, if there are any, since there are well known advantages over SLR optics. I got the G2 after years of using a Contax SLR, and I can attest that the G lenses make nicer pictures. The 28 G vs. 28 SLR is a difference easy to see. Or is it? I've never taken the same picture with both and compared. Maybe I'm just programmed to assume the G lenses are better, and "see" accordingly. Really a very special kind of empirical comparison needs to be made before one can make assertions of this kind "from experience". ------------------------------ Date: Thu, 2 Nov 2000 11:28:39 -0800 (PST) From: Roger To: hasselblad@kelvin.net Subject: RE: Question about real need of a vacuum back...

I don't see your connection, since I shoot a variety of formats: 35mm, 6x6, 4x5, 5x7 and 8x10. Use the right tool for the job. I use nothing but Zeiss for 35mm, same with 6x6 (80mm Planar and 150mm Sonnar). I do have a Pentax 67 with Pentax lenses, and for the LF, I use either Schneider, Rodenstock or Fuji. --- Shane W Davis wrote: > I wasn't seconding the claim; I was just asking how > one might test it > (cheaply), i.e. empirically verify or falsify it. > The claim's being > false, however, does not logically follow from any > of your shopping or > emailing patterns. :) > > On Thu, 2 Nov 2000, Roger wrote: > > Since I also have Contax > > G1 w 28mm, 45mm and 90mm, and am a subscribed > member, > > the 80mm chrome will look better than one produced > by > > the 45mm. > > > ---------------------------------------------------------------------- > > The Hasselblad Users Group Listserv is a public > service of Absolute Internet, Inc., which is not > responsible for its content.

Then, I wanted something smaller to tote around, and fell in love withe Contax G1, with it's silky smooth mechanics. Wasn't too long after that before I got rid of the Nikon. Old slides taken with Nikon look ok - as long as you compare them only to other slides taken with a Nikon. I didn't bother do a scientific comparison, because I don't have to convince anyone but myself, and from what I saw there was enough difference to switch equipment. Oh, I liked Leica too, but just couldn't afford it. Contax gave me equal quality at a fraction of the Leica price.

Message-ID: <20001102194303.15303.qmail@web3106.mail.yahoo.com> Mike, Linhof has vacuum backs (probably for aerial cameras), Rollei has an outrageously expensive back for their 600x model, and possibly Beattie has a long roll back that might be worth investigating but I'm not sure if it is vacuum. The Beattie long roll back is powered by a car battery or an AC outlet if I'm not mistaken. --- "Michael R.

Will my screen say Acute Matte on it? If it doesn't say so, will just say Hasselblad?
