I was shooting some 8x10 HP5+ on the weekend and realized part way through that my meter was set to 100, not 400. Naturally, it was a low contrast scene shot on an overcast day, so I know that overexposing and underdeveloping is exactly the wrong thing to do.
My one saving grace might be that it was a 4 second exposure, and I didn't add any compensation for reciprocity failure. If I read the exposure compensation chart right, I'm probably just about right for normal development. Any agreement/disagreement with that? I was planning to develop in Xtol in a Jobo, other suggestions welcome. Should I be using a lower energy developer, such as Perceptol? Dilute Rodenal?
The metering was 4s for ASA100, or 1s for ASA400. Eyeballing the reciprocity failure compensation curve, it would be a bit less than (12.5/5)*1=2.5s.you should have nailed it -those two stops will balance out forgetting reciprocity compensation.
Metered exposure was 4s F45 @ ASA 100.The metering was 4s for ASA100, or 1s for ASA400.
That's sort of my gut feel too. I'm mixing a fresh batch of Xtol and I will find out! I realized the meter setting error while I was there, so I have a sheet at the "correct" exposure too. I'll develop them one at a time and see what I get. I have 3 sheets in total of the same scene (plus digital for insurance!)you should have nailed it -those two stops will balance out forgetting reciprocity compensation.
When is it a flat developer and under what circumstances i.e. how can it be made to develop flat?hi craig
xtol can sometimes be a flat developer, i think you will be fine.
good luck !

The latitude of most films is from 4-1/2 over to 1 stop under exposure. Just develop the film normally. Negatives will be a bit denser than usual but will print correctly. By attempting to compensate by reducing development time you will effect the negative's contrast and tonality. BTW, many people normally over expose by 1 stop for the very purpose of better tonality.
Thanks jnanian. I have heard of the Church of Rodinal so is caffenol a break-away movement for the Church of java? That's Sam Spade's "java" and not the place where a volcano exploded
