I have Canon EOS Rebel XS but can't not take picture from my tank very well.

It is bow front tank, anyone know what to do to improve the shot?

Thanks

I bought a submersible housing for my Canon PowerShot so that I can just put the camera right into the tank for good closeup pictures. A ziplock bag might even work but thats taking some risk.

Only way is to go top down or through the side. You have to have the lens perfectly perpendicular to the glass to get a good clear macro. Unfortunately with curved glass this is impossible, which is why most people into photography don't by bow fronts or other curved glass tanks.

Best solution is make a top down camera box, it's a simple DIY project but don't use a Ziploc bag as I assure you this won't work.

Can buy a topdown viewer from RedCoral that works great for topdown shots.

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

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).

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