Developing B&W Film: Part II - Using Massive Dev App for Film Development

- Part two (or one and a half?) of a multi-part series on film development. In this video I provide an overview of the Massive Dev Chart App, which is a GREAT boon in the development process if you have an iPhone or an Android device.
Glad you think so. Thanks for your comment.
I still use the Kodak black and white darkroom data guide from the 1980's with the silver cover.
I believe the formulas are "crowdsourced", so the app only has formulas that people have contributed. I've never even heard of promicrol (not that it means much), so it's possible that the only contributions have been from people doing push with it.
You should be able to reduce development, as a general rule, by 20% per stop, and you can create yourself a custom formula based on that.
Thanks for watching my vids.
Not sure why one would be wary. A container of water that has sat in a room for a while will be room temperature. It's not like it's a lake or an ocean.
Anyway, I'm open-minded, so I just did a simple experiment. My digital thermometer read 66 degrees F in the dark(bath)room. I took the temperature of one of my containers of water using my chem thermometer and it measured 66 degrees F. I think I'm in the clear :-).
Hey, i'm totally for a push/pull feature in that, overall awesome app. But maybe you can explain me why it offerst different speeds (eg. im doing tmax 400 in promicrol 1+14, and the app offers me only 600-800.) Though i shot the film with 400, so far it turned out fine, maybe because tmax is a new emulsion. If you have an idea on that, it would be awesome. Like your vids by the way.
I'd be wary of assuming the air temperature is the same as that of your developer, there is likely to be some difference.
can use thegiven numbers for expired film as well or just fresh films?
+Garubolas I think that expired films are more of a wild card. If you have a lot of expired, say Tri-X, then I'd try the standard numbers for an experimental first roll and see how things go.
Or, look to see what the internets say about it. I've never looked, myself. Might be interesting.
