Grace Robertson link told me that she came out of a tube station and found someone selling posters of her photographs. She went into a nearby florist, boorowed two buckets of water and destroyed the guy's stock

Lenses used in cinematography such as multi coated Carl Zeiss Distagons still have both T and F indices. T for aperture and F for calculating depth of field. However in real terms the physical difference between the two, especially on wide angle lenses, is miniscule; I've never believed there would be any noticeable difference and given the vagaries of the various methods used in the production of depth of field tables the whole thing becomes very subjective indeed.

Too late then to correct the squint horizon

I hope he's OK Gwyn

Those are really good. I tried it a while back but lost patience because I couldn't seem to match focal lengths. I'll give it a go again with your warping trick.
