    Contact printing 35mm to 35mm

    It'll work well either way. You can flip the b&w neg with no loss of quality. P.S. I use tmax 100 for duping from slides.

    Advantage of 6x8 over 6x7?

    No, I don't think so. Mind you I only had the pro SD so I can't say whether previous RBs might require some adapter. I don't think so; I think they all have pretty much the same graflok attachment on the film side of the rotating adapter.

    Advantage of 6x8 over 6x7?

    Sounds cool. So you are making some sort of insert so that the film will be held reproducibly in the same spot? Or you could simply tape it down. What lens are you looking for?

    Advantage of 6x8 over 6x7?

    I like 6x8 a lot. I don't feel any need to justify that, I just like it. Yes, there are some technical advantages and disadvantages i.e. less cropping for some standard paper sizes, but... in the end everybody's artistic vision is individual (or should be). I mean, basing these things in what...

    Where do I begin?

    My offer in post #13 remains... ;) Crown graphic. A full kit with lens should run you ~$300. Add film holders and you're in business. Later if you decide to get another camera with more movements and such, you'll still love your crown. No problems, it's easy. There are vast resources...

    That's the very definition of green, isn't it.

    C41 E6 Green

    Yep, I agree that photography's share of the silver-related compounds dumped into the environment has gone down drastically, and maybe that is part of what's behind the low silver prices over the past few decades. Anyway, I default to my original answer ;) Anthotype is green. Regarding...

    C41 E6 Green

    There's a lot more to the overall process, though, Ron. The film bases are a petrochemical product, and a lot of the world's silver is still mined in an environmentally damaging way or obtained through mining of other metals. There is no free lunch: the methods to obtain these materials are...

    C41 E6 Green

    The greenest form of photography would be anthotype ;) As Ron noted, the electronics industry as a whole (including the digital photography sector) is not at all green. Neither are the b&w, c41, nor E6 processes.

    Making larger format negs?

    Oh sorry, just noticed that this was a question for colour. This opens up the possibility of doing an E6 enlargement, so there'd be no need for an interpositive- the slide would itself provide a suitable negative image for ra4 printing. I haven't done it but I think I'd try that. Something...

    Making larger format negs?

    Sure, enlarge to ortho film. Just google "enlarged negatives." N.b, if you try to search for that using the APUG search engine, you won't get much; use google instead.

    For Sale FS: Nikkor-T*ED 360/720 Convertible LF lens

    This is the rare and excellent convertible tele T* ED lens for LF in a copal 1 shutter. You'll get two interchangeable rear elements providing 360 and 720 mm. The main advantage of this lens is that you don't need long bellows draws. I am no longer doing tele stuff by LF, and I am doing...

    Fuji 150mm 5.6 W lens

    Slitting film precisely (lengthwise)

    Thanks for the inspiration Simon, I will certainly do it now. I've made a pretty good career of "shouldn't dos."

    Slitting film precisely (lengthwise)

    True, but you could set up the job in room light. P.S. I have a diamond wire saw, that would probably be the best way to go.

    Slitting film precisely (lengthwise)

    I am thinking of trying the following: wrap the film around a cardboard core, then wrap a foot or two of black paper around it and tape it so that it's really held firm. Cap the ends to prevent light leaks. Then use a saw or guillotine... I have 5" roll film and have been thinking of...

    Sekor C lens for RB67 Pro SD

    JW, it really depends how much colour you shoot, in my opinion (and as photoncatcher implied). My own take on this is that the price difference is really small, when you consider the benefits of the newer lens. Besides the advantages of being newer (remember these are all-mechanical lenses...

    Visiting Washington D.C. on Friday, what should I see?

    The snow will be gone, no worries there. But do bring good walking shoes and a packed lunch and drinks- you're in for a good hike. You'll very likely need to park a mile away or so. My advice would be to stay in Arlington and get shuttled.

    Visiting Washington D.C. on Friday, what should I see?

    P.S. Stop for lunch in the cafeteria of the museum of the native americans. Unfortunately, apart from that and the atrium of the building, there isn't much else there of note (as a Cherokee descendant I was hoping to learn a lot more there). That cafeteria rocks! Best food on the mall, bar...

    Enlarged Negatives for Printing

    An enlarged neg will not have the appearance of less grain unless the duping material itself has substantial grain. here's the reason: the grain in the original neg will be magnified in the process of going to the interpositive, and that grain will dominate the grain of a fine-grained duping...

    Pentax 67 sharper than Hasselblad?

    I am not sure (with no examples to look at) but the issue you see may be more to do with contrast. Bear in mind that if you don't require creamy bokeh, then there are indeed contrastier lenses than can be found in the Hasselblad and Mamiya families. My own assessment (which I am well aware...

    Can't handle photography anymore (rant to self)

    Frankly, I really don't understand the advice that the creative obstacle needs to be machine gunned, rammed, pushed, just do it-ed etc. It all strikes me as machismo. I was assuming, when I posted my suggestions, that the technical stuff was taken care of. If not, then yeah, push away, and...
