Reciprocity failure

Leigh, he can't "devour" electrons.

Sure he can. Sequestering them within his digital media, thus removing them from circulation and isolating them from their brethren.

They don't even get visitation rights on Thursdays.

pfitz, which film are you using? I typically use HP5 and for exposures that are 1 second I add 1/3 stop more exposure. 2 sec I'll give 3 sec instead; 4 sec I'll give 6 sec; 8 sec I'll give 12... I have a graph that I made. This also applies to FP4. No exposure compensation is given. Some films require more exposure, some less like TMY.

Stop right there for a minute and let me catch up.

What compensation? Where? The Lab, or in house developing? In camera? Which I wouldn't know where?

Thanks

Super simple answer is reciprocity compensation is about exposure time.

But sooner or later the storage media deteriorate - unless he throws it into a particle accelerator/collider the electrons will eventually be back in circulation; perhaps as part of an even more annoying medium.

I hate it when people do that. Even if the question isn't that great. If the only thing on this board was topics that hadn't been covered previously AT LENGTH, there would be no discussions...

It's also often about development. With color materials, filtration rears it's knobby head.

No, Vinny's right. The OP needs something to read while we amuse ourselves. And reciprocity has been covered at length, here and elsewhere.
Personally, I'm done answering questions and explaining simple things to posters who can't be bothered to bestir themselves and look it up.

Hey, that's not nice. I'm a member of APUG too and that sounds like what you're describing

The compensations that manufacturers suggest are given with the assumption that you want an image with a normal tonal range. I like to think of RF as an opportunity to get some deep black areas if you don't do the compensation, or maybe just not as much.

You can get that by underexposing.....
