This image was shot w/the AeroTessar w/the rear element of the front cell unscrewed about halfway out.  It's a shot of what came into existence as a fruitbowl which has a series of thickened 'ribs' around it's circumference.   I picked this thing up from a discount store, and realized immediately that the ribs on this bowl formed a series of magnifiers around the outside of the bowl which I could use in playing around w/reflection and distortion.

I cut one of my flat plastic page magnifers so that its corners would sync up with the edges of the bowl and pointed one of the corners in the direction of the camera, and placed the bowl over the magnifier on my brushed aluminum.   The striated lines you see aren't on/in the bowl, I assume they're from the grooves created from the fresnel pattern of the magnifier and being magnified by the bowl, also the 'zig zag' effect from the bowl sitting over the magnifier is from distortion and of course the edges of the flat page magnifier are straight.  

This has not been photoshopped, nothing has been added or removed.  This has been one of the more interesting curios I've ever lucked up on.
