Hi again, Steve. Yes, it is much better with the verticals corrected. Many thanks. As I wrote, at my gallery on this image, I did consider using the straighten tool on that vertical area, but wasn't sure how it would affect the round area of the building. I must return to my version and see what I can do with it :)

Tania, if you look at Alandra's original version thelensflare.com/gallery/p_libraryblackwhite_40855.php you will see that walls at the edges of her picture which in real life would be vertical seem to be leaning inwards. This is because when Alandra took the picture she had to hold the camera at an angle so that it was pointing slightly upwards, otherwise her shot would not have included the top of the building. This happens in our eyes as well, but our brains are so clever that they are able to compensate for what the eye sees because we know what the real world is like. A camera can't do that, so we have to do this for it by using software. If you look at my version you will see that the walls are parallel to the edge of the frame - in other words they look vertical. This is most obvious in the bit of the building at the right hand side of the frame. (Actually, I didn't do this quite perfectly, so they aren't quite right!) This process is called "correcting the converging verticals". Hope this helps!

Steve a wonderful work, indeed with a bit working out, some photos force up to the best.

Thanks of your engagement!
