Hi, I've just spotted reference to the 'taco' method for developing sheet film on 'another thread'. I've seen this mentioned quite a few times in passing on APUG, but haven't found a clear explanation as to what it is. I think I know what a taco is - but I'm not sure how folding a film in half, stuffing it with mince, cheese and chillies and bunging it in the oven will help. Can anyone explain this one to me? Thanks.
