Frosty morning

Or just tilt the easel. You have to stop your lens down quite a bit, though.
What's the dark blob on top?

Yes, I could just tilt the easel too. As I said it looks a bit odd though as the keystoning is not completely regular, will take some finagling.

The blob is the sun and/or lens flare. I kept it out of most of the shots but wanted to include it in some, see how Delta 100 would handle it. I could dodge it out of course.

Sorry for the ignorance, I know what keystone means, but keystoning? I couldn't find the definition at the dictionary.

When you tilt a wide angle lens (24mm in this case) up, the perspective and relative distance makes things which should be straight up tend to bend toward the middle of the image. This forms a keystone shape so it is called keystoning. Look at the telephone poles here and notice how they look like they're bent in. I don't think they're really like that though I may have to check to make sure.

It can be corrected with a tilt lens on the negative or by tilting the easel or the enlarger head and using a stopped down aperture so the focal plane is deep enough. I shall try to print this one again to see if I can straighten out the telephone poles.

Yes, unfortunately this lens isn't that well corrected so I wasn't able to de-keystone it. I'm beginning to wish I'd stuck to prime lenses in EF like I did in FD mount. Might have to sell the expensive L zooms and rebuy some primes though the cheap primes aren't really any better and the expensive ones are really expensive.

The Canon EF 24mm tilt-shift is $2700 but I hear it is pretty good...
