I have to confess that I left everything in green mode, because I couldn't see a thing without the torch, so the situation was, shall we say, challenging?

Camera and flash sorted themselves out and I worried about the composition and making sure there was at least a spot of light for the AF to focus on.

The LED Lenser Police torch I was using was excellent, far brighter than all the hige torches that people brought.

And death:

Nobody really knows for sure, but one thing is certain. The canal used water from two other canals as well as getting it from rivers, so the other canal owners would be protecting their water supplies. Therfore pumping water back up the canal seems very logical, but very costly.

As soon as this short cut opened the other round-about route dropped its charges...so the Manchester & Salford Junction canal was doomed from the start from every angle.

It's just over a mile and a quarter long I think, and all in tunnels, connecting the Bridgewater and Rochdale canals.

The tunnels were used in WWII as air raid shelters, so they may have been constructed as goods lifts. In the past few decades they have been dry and abandoned, with some , but not much, signs of the occasional squatter. Most of the access points are firmly bricked up, but there is a relatively new stairway within the Great Northern Warehouse that allows controlled access.

A group of local enthusiasts arrange tours and we had an exclusive tour for the camera club as one of our members works for the people who arrange things.

IIRC the canal closed in the 1920s, never having been profitable due to its high maintenance costs. The rest of it lies underneath Granada TV Studios and they probably use it for filming.

The tour is generally available, Google will reveal all, and well worth the £10 it costs. Fantastic atmosphere down there and also easy access so most people will be able to get down there.

Under Manchester is the defunct Manchester & Salford Junction Canal. This image shows one of two mysterious towers built on the canal basin bed. The function of these towers is unknown.

Shot in total darkness with the K20D, 16-45mm, 360 flash, 400 ISO. AF was accomplished by focusing on an area lit by my torch. Very impressive, very low light focusing from the camera. No problem whatsoever locking on....

You can correct the tilt in Photoshop and also correct converging verticals and horizontals as well.

The quickest way to correct a tilted image is to use the crop tool - resize and rotate at the same time.

Otherwise, the Transform tool is an effective method.

I don't usually notice adverts, but from time to time someone advertises something that I actually want to buy. If I turned off the adverts how would the suppliers ever get to tell me about it?

I'm not sure that there's anything intrisically wrong with advertising - it's what many of us here do when we want to make our photographic services available.

How would we know who SRS were if they didn't advertise? Knowing who they are has been to our advantage...

Modern zoom lenses for still cameras don't necessarily hold focus very well when zoomed, so the technique may not work.

Or be very traditional, and ask them to send you a cheque.
