Just curious but couldn't a warped image be shaped flat with some good post processing? It's just geometry right?

Nope

You're right but it's not that simple.

We do this all the time in my industry (flattening lens distortion, warping CG images to fit existing lens distortion, creating 'clean plates' etc.)

Depends on how much distortion you have. I'm guessing you wont have the image info needed to 'unwrap' the distortion from a bow front, but you could take 2 or more images & then stitch them together (with a little warping into shape if needed).

Or you could upgrade and sell me the bowfront!!

Its not really just warped, but rather the image is distorted

Sorry but I disagree, Theses are macro through a bow front.


I have more photos of angle shot going down the length of the bow and they turned out. The quality of glass ? What make of tank?

It will depend on the angle of the glass vs. the angle of the lens. Try to keep the plane of the film/ccd as parallel to the glass as possible to minimize distortion.

ok, i tried all angle and could not minimize distortion. Anyway, I am picking up this http://www.newegg.ca/Product/Product...82E16830112033 so i can film it too :-) and take micro shot. Will see how it goes

Do you use special lens?

Disagree with what?? You can still take macros through curved glass but the results simply won't be as good. The effect is probably worse with SLR cameras due to the larger lenses they use.

Also your macros are good and I would even say excellent considering the camera you used but there is clear evidence of distortion which gets worse the further away from the center. You'll see this effect even with a larger DOF and is a result of the curved glass.
