I believe this is due to the camera being tilted back slightly? A wide angle lens not parallel with the subject will always display this phenomena. It does not spoil the image for me.
Edit: I should have said 'any' lens.

Barry is correct. The camera back should be perpendicular to the subject to avoid the effect you describe, but this usually then includes too much foreground. The solution is to use a shift-lens.

Barry + Dave are correct here, this effect is called converging verticals, barrel distortion is when the lens distorts the image like the name suggests in a barrel shape like this () so straight lines become curved top to bottom and left to right, usually most associated with wide angle lenses more noticeable on extreme wide angle lenses.

You can sometimes correct the convergence by tilting the enlarging easel and compensating the print exposure by 'dodging and burning' but you would also need to stop the lens down as much as possible to give sufficient depth of focus. However I agree with Barry and Dave; it looks fine as it is!

Interesting. I didn't notice the leaning tower until I read the description. I don't find it a problem at all. I think my mind naturally adjusts for it.
Great image - the 'decapitated' trees in the foreground seem to send a subliminal message (I've no idea what it is though!)

Wide - angle distortion can be used be used to good effect in i/r work and with this image I am not bothered by it as it is a clear creative interpretation. However, if the image was meant to be faithful reproduction of the church (applied photography) I would be looking at it differently.
I use a wide lenses (17mm to 35mm) a lot with creative 35 mm i/r work and if the subject looks a tad too distorted
The tilting base board trick at the printing stage often does the trick to reduce the impression.
Nice i/r work Vincent.

Thanks everyone for your comments. I have one of those small spirit levels for camera use so it looks like I should use it more often. I had already photographed the church from within the grounds but it was only on leaving that I noticed the stumps of trees. As Rob pointed out I was trying to capture the echo between the cut down trees and the abandoned church in my composition.
Thanks again everyone.

Vincent, my sentiments are as per Rob. You have to look quite carefully and even then only see it in the tower. The black sky immediately above the missing roof acts like a roof and is a nice touch.
There is something about IR and derelict buildings. They go together perfectly.

Thanks for that Mike. I think you are right about derelict buildings and IR, I know I have a good collection of shots featuring them. I'm inclined to file them all under the title of 'Forsaken Dream' although a church would hardly fall into that category.

Hi,
I'm new so what do I know? I really like the picture, no problem with the distortion, it's acceptable. I think there is some imbalance, tower on the left and open sky on the right, exacerbated by sightly cluttered left foreground. Also the sybolism of the trees is magnificent, doe they signify the potential for new growth, or the decline of ancient faiths, or the lack of patience of modern society with past roles and ceremonies?
I wish I'd taken the picture. Thanks, Graeme

Thanks for your comments Graeme. I saw the trees being cut down relate to the derelict state of the church. The fact that there are 3 of them could could be construed as representing the 'Holy Trinity'. But maybe that's reading too much into it.
Welcome to fadu by the way, you should enjoy yourself here .
