In this week's AP Answers, Barney Britton gives some advice on the Olympus 35 ED. Tell me, has he got the advice the wrong way round? Surely, if you have an ISO400 film in your camera and you tell the camera that it is an ISO200 film, you are going to over-expose the film, not under-expose it? Isn't that the same as dialling in +1 stop compensation?

Yes.

That confuses me ... I never learned to use compensation controls, perhaps because I do understand the relationship between light level, shutter speed, aperture and film/sensor speed settings.

Yes, you're completely right. It's always the things that know inside out that you end up writing down wrong. It is of course the opposite way round.
The other problem with that answer is that I appear to have answered a different question to the one asked by the correspondent. This is the result of editing down my (somewhat longer) original answer. I corrected the inconsistency on a proof, but it seems that I didn't update the document in the correct folder, and the uncorrected version made it into print.
My apologies. Damien is out of the office this week but I have no doubt that he will give me a good whipping on Monday.

Thank you for the reply, you have put my mind at rest - I thought I was going daft! (Some would say I already have gone!)
