Efke IR 820 (@ ISO 1.5), IR Filter, Rodinal 1:100 semi-stand 1h
Got this 4x5 Efke infrared film from a flickr contact. Unfortunately this very rare film seems not have to withstood time (and maybe some radiation at the corners?) without damage....
any tips how to understand the exposure on the outer part of the film are welcome (or if this could be due to mishandling during exposure or development?)

15mm front fall, and lots of front tilt (possibly a bit too much in fact but in a bit of a hurry!)
First outing for Rodenstock lens, proved its worth with amount of movements possible.

A couple of weekends ago I went a little crazy and decided to bring my large format camera to a rally with some hopes of bringing some experience back home :-)
As it turns out it was not impossible at all ;-) Bad thing though, I shot three frames and one I forgot to push, and the third I double exposed with some other shot :-/ but atleast I got this one!
I came to Assateague Island Seashore to find an open space to practice a little with panoramic format of my Horseman 6x12 film back and a roll of Ilford Delta 100 film. This photograph is, probably, my favorite from that day.

A little table I've worked up in Excel. I *think* it's accurate, following the formulae available online for bellows factor, bellows extension, and total working distance.
B = total bellows extension
W = working distance
T = total distance from subject to film plane
dimensions in inches at top are subject size dimensions.
I've already used this successfully once so it's pretty good I think.
Why is this useful? Because working out lens choice and setup for large-format closeup work can be tricky, especially if you don't have a tape-measure with you (but no self-respecting large-format photographer should be without one of those, surely??). Depending on whether a given camera front focuses or back focuses or both, setup can be time-consuming.
Using this table, I first figure out roughly what the subject dimensions are, then figure out roughly where I am in terms of magnification and which vertical part of the column I'm on. Depending on how much working distance I want or have available, I would then work down the list of lenses and select the lens I need (or indeed have) and set up the camera roughly according to the total distance indicated. Some adjustment is required for in-between magnifications, but that's much better than wasting half an hour guessing and getting frustrated.
Measurements with underlines are amounts of bellows extension where I would need to use the extension board for my Chamonix 810V (without extension, bellows is limited to 680mm; with extension board, this extends to 850mm). I haven't therefore included bellows lengths that would exceed 850mm.
Having a reasonably long QR plate on the camera also helps. I use a Wimberley P50 on both 8x10 and 5x4, which is 167mm in length.
For time to add, I use the reciprocity timer app for consistency with bellows extension calculations. It automatically calculates reciprocity time and adds this too, according to its own formulae.
