Delta 100 is also a tabular grain film like T-Max which gives both these films a finer grain for your ISO buck.

You are assuming you get the correct proportion of each chemical that makes up D-76 shaking the bag or not, I guess. I suppose it's close enough. D-23 is only 2 individual chemicals, mixed single-shot and I don't think you can tell the difference between it and D-76 with a figital workflow.

Old HC-110 found in pharao's tomb is still working

I was just making the point that ID-11's shelf life has to be viewed from the mixed working solution; whereas, not so with D-23 (same dev times as D-76). I'm a fan of long shelf life, single-shot developers. They are economical for someone who periodically develops film. I don't have to bother with shelf life, time compensation and/or replenishments with developers. Those attributes just add more variables in the development process. Single-shot avoids all that and helps yield consistent results. I use Rodinal often too. But I avoid using it on 'short-toe' films for general photography.

How easy is it to accurately mix, say, a single-shot, 500ml working solution from a two-part ID-11 that must have more than one chemical in at least one of the containers, I wonder. You'd be assuming that you are getting correct proportions of each when you take out a portion from the bag; otherwise, you would need mix the full contents to be sure, I suspect.

I dunno. Kodak doesn't say HC-110 has a long shelf life. They give a table of recommended shelf life in their HC-110 Data Sheet for the stock solution once opened.

PMK Pyro has a advertised 10-year shelf life. And mixing your own single-shot D-23 (just two dry chemicals) has a very long shelf life in its powdered form.

6x4.5 format is already a half-frame to the 'full-frame' of the 6x9 camera format. So it's a half of a half-frame, eh? Just kidding.

Thanks. If you use the folding hood instead of a prism, you can save a lot of bulk and weight. And I don't find it hard to it take along. The thing is, long after the picture has been taken, I have no regrets hauling this camera over taking a more convenient small format camera when it comes to making prints.

Pentax 6x7 film selection switch stuck -- frame spacing?
Posted By tuco

I get variable frame spacing with 120 film on my P67 as well as my other medium format cameras. It is a friction feed and the thickness of different films affects that. Some films are very thin (eg RR80S, RPX25, Acros) and problematic with variable spacing while others like 400TMY is nice and thick and does well in terms of spacing.

You also need to adjust the pressure plate for 120/220 film. While I have never used 220 in my Pentax 67, I doubt the frame spacing would be any different than with 120 roll film. 220 roll film is twice the length of 120 roll film to get the extra frames.

Those canisters are worth saving. Maybe take extra care removing the canister ring when you develop the film so you can reassemble it.

Yes but the dilemma is still there shift lens or software. If you correct so much that it doesn't look natural, what has been gained? Unnatural geometry or converging lines, pick your poison.

Shift lenses (a special case to correcting converging/diverging lines) works by leveling the camera and standing back far enough away from the subject to shift the horizon down while keeping the subject in the frame. If you are up too close, you need the ability to tilt the sensor plane like a view camera can do by tilting its rear standard (the general case to geometry correction).

I gotta ask myself, Ed, when you geometrically correct in software that much, does it look any more correct than one with otherwise converging lines, I wonder.

Updating an older picture. Acros was good for simplifying my metering by not having to compensate for reciprocity failure in my exposure.
