Building vs Blue

Building vs Blue
Originally uploaded by jezza323
Here is an abstract shot I took last year. It is a building found on Ann St in Brisbane, with a nice pattern to its windows, contrasting against the clear blue sky (haven't seen many of those lately!)

This one was taken with the Pentax SMC F 35-70mm f3.5-4.5 lens and Pentax K200D body. It was processed in Lightroom, and then I used The Gimp to apply a small amount of perspective correction. The last step I had to do because I was shooting looking up, so the lines were not quite straight.

Perspective correction basically squeezes 1 end of the photo, to correct the converging lines you get as things get further away. In this shot the line between the building and the sky was sloping slightly from left at the bottom of shot, to right at the top of shot, even though I was cropping the image with the line of windows at the right side straight up and down.

Here is a good example of a much more extreme perspective correction on a shot.
