Hello
nice picture. you are using a Kodak easyshare M1093is which is fixed lense camera. The Tilt Shift lenses are for SLR's and used for correcting the abberation which you pointed out. Unfortunately you cannot change the lense on your camera. Your camera has a lens with 35 mm equivalent: 35–105 mm. this problem occurs when you open your lens wider than 50mm. Generally for such situation i do a vertical panorama ie., take a continous series of pictures one after the other at fixed focal length of 50 mm and each picture overlaps the succeeding by 1/3rd. then i stitch themup to make a composite single picture.
but the rules are :

Focal length should be fixed ie. 50 mm etc
the aperture value and the shutter speed should remain the same for the complete series of pictures or else you will have problem while matching the points on two photographs and the gradient will be of different exposure.

try it out and let me know

This is a very easy fix. If you have Photoshop on the top tool bar go to select click on all then go to edit>transform>perspective. there will be a line that goes around the entire image with a square on each corner and a circle in the middle of each horizontal and vertical line. Place your cursor on one of the upper corners left click and hold then drag the corner until the architecturals are straight up and down, release the mouse and click "enter" on your key board. At that point the buliding will be "rectilinear" (straight up and down) but may appear stumpy. Open a new document larger in size than the building. Drag the image of the building to the new document. click on select and select all of that layer that contains the building. Go to edit>transform>distort. Place your cursor on the top line and drag it straight up until it looks correct, release the mouse and click enter on your keyboard, go to layer on the top toolbar and select flatten then crop the image how you like it. For sure using a tilt shift lens is a better, and easier, fix but they are very expensive and require learning before they are used correctly. The other alternative is to use a view camera.

Couldn't help myself :: Photoshop method (sans lens correction, just using transform)

I do think a tripod and about nine photos, three rows of three each, stitched via PT GUI (google it) would do it justice.

Thanks for asking the question Feily - I learned something today. GIMP has this feature also.

Great advice from everyone nothing really to add except you don't have to have the whole building in your photo - like this one.
