Is there a Massive Reciprocity Chart to match?
You're running an Android phone aren't you? There is a good reciprocity app I use called Exposure Assistant, its accurate enough for everything I've tested bar Delta which is not anything like as bad as Ilford make out.
A single data point means nothing however
I'm starting to question the massive Dev chart app if I'm honest. Last few rolls I've used the manufactures timings instead. There some pretty big diferances. Interested to hear what others are experiencing. I've got so little experience I can't judge the outcome yet
Should ad, I'm only using hp5 and tri-x with d76 1:1. From 400-1600 so far
Are they pretty big differences in timings or results?I'm starting to question the massive Dev chart app if I'm honest. Last few rolls I've used the manufactures timings instead. There some pretty big diferances. Interested to hear what others are experiencing.
Don't stick to a developing recipe just because the Massive Dev chart says so.
Massive Dev Chart only provides one possible starting point. You may also want to consider the developer manufacturer's recommendations, the film manufacturer's recommendations, the advice of other photographers, your own personal preferences, or any combination thereof. These various sources may provide the same starting point, but not necessarily, even for the same developer and film, so you'll likely need to experiment and adjust your exposure and development accordingly.
