Spedman posted:Holy poo poo that is awesome. You don't normally thing of things like launchpad cameras in shuttle launches but a ton of engineering and care were involved in setting all of that up. The specialty time codes in between the sprockets, the gas filled protective containers the cameras have to be set up in, keeping the tungsten lights from shattering in the units that store the umbilical apparatus. Even the custom aperture control to automatically expose for rockets. And the sheer number of cameras and feet of film involved in capturing everything.

You would only need 5 system4 patterson tanks to do that all at once, if you stand developed.

When it comes to exposed c41 film that has been sitting around in a drawer for a decade or two... push a stop during development, or just work it as usual?

Can we play another round of What the Hell is Wrong with my Negatives?  There's this roughly (occasionally wavy) horizontal line through my entire roll of Tri-X 120. Shot with my RB67, dev in HC-110 1:47 for 6:30. What the hell is wrong with my negatives?

I think you've either not used enough dev accidentally, or the reel wasn't sitting at the bottom of the tank. Could also be not enough agitation.

Tank needs 590 mL for a roll of 120 and I mixed up 600. Agitation was 5 sec every 30 after 1 min initial. I know my fixer is a little old but doesn't smell or look worse than usual. Developer concentrate is still normal yellow. Temperature is probably suspect because my thermometer has been sketchy lately. Could it be not enough fixer?

Maybe if you didn't use enough of a volume of fixer, but the strength should be fine if it smells like fixer.

VPL is apparently tungsten-balanced. I wonder what the reciprocity failure curve looks like on film that expired 36 years ago

Most everyone says Citizens Photo in Portland. I may hang on to the film I shoot over the summer and develop there when I'm in the area in September.

I bought a Fujica ST705 a couple of months ago and have shot three rolls of C41 so far. It dawned on me last night that I don't know if the shutter timing is accurate and I don't want to develop film until I've got a larger batch (don't want to waste chems). Is there an easy way to verify shutter timings? I could burn a roll of HP5 and develop it the same day, if that makes it any easier.

Film has such a large dynamic range that you won't really be able to tell if the shutter is off unless it's off by a large amount (2-3 stops). Anything smaller like 1/2 to 1 stop will be unnoticeable pretty much. There are a couple phone apps that pretend to be shutter speed testers, but they are really inaccurate at anything higher than 1/250. Basically it uses the phone's microphone to record the sound of the shutter, then you look at the waveform and align two "end points" where the you see the shutter noise start and then stop. Then it tells you the speed. If you are handy with electronics you can make your own that's super accurate. It is a rather simple circuit with a few resistors, capacitors, a phototransistor, and output to a 3.5mm audio jack. Plug it into your soundcard and record the "audio" it generates. Meanwhile shine a light through the lens (any small flashlight will do) and place the phototransistor in rear of the camera. Fire the shutter, and check out the recorded audio clip.  I think I used this schematic for mine - http://www.mraggett.co.uk/shuttertester/shuttertester.htm

Thank you for that, it looks simple enough. I wonder if anyone sells printed PCBs for this. Time to look around a little bit. I just want to make sure that the thing isn't hugely off before I shoot another 10 rolls with it.

I bought a 100ft roll of HP5+ 400 a few years ago, threw it in my loader, pulled maybe seven rolls and then promptly stopped using film. Pulled my gear out today. The film has been in a sealed plastic bag, in the loader, at room temperature for probably 3 years now. What are the odds that it's still usable? I'm not expecting much, but then again if a new roll is just $65 I'm perfectly fine popping that loader and using the old film to TP someone's house.

It's fine. Film usually has an expiry date of 3-4 years so if you bought it fresh it's likely only approaching expiry now. And film expiry dates are very subjective to begin with.

Just use it. Try the first roll to check if you need to do any exposure compensation (you won't) and that's it. I'm running Tri-x that expired 3 years ago, kept in room temperature, and it works just like new.

It will be fine. I recently shoot a roll of HP5 and two rolls of FP4 which has expired about 30 years ago, and has been stored in hot attic for at least 5 years. The results were surprisingly usable:  000005 by Vidak, on FlickrThis is HP5, unsurprisingly FP4 has aged better. Gives me good hopes for two boxes of Pan F I have in freezer. I'll post more pictures when I get home from work.
