Landscape in a coffee cup

by OldTaffy

An experiment, a bit of fun. We sometime make a Greek 'metrios' coffee (approx = Turkish coffee) and my wife likes to swirl the dregs around the cup to make imaginary landscapes or seascapes. This panorama is from one of her cups.

Cup on a gramophone turntable, K-S2 on a heavy tripod looking down into it with a Sigma 105mm f2.8 DGMacro lens at f22. Illumination: one 4000 °K LED bulb in a reflector. Rotate turntable 16 times, 22.5 ° at a time and take 16 photos. Crop out one narrow strip from each image and stitch together with MS Image Composite Editor.

It's all a bit of a fiddle, and this one hasn't quite worked out because the primary cropping was a bit hit-and-miss, and I didn't bother to correct for perspective in PSE, but in principle it works rather like the more conventional "rollout" technique for flattening the surface of a cylinder. See: link
The actual set-up was very 'Heath Robinson', involving a step ladder, G-clamps, bits of bamboo as well as the gram turntable (I have photos!).

An interesting image and an interesting explanation. A lot of work has gone into this shot.

I already wrote almost the same comments but I guess I forgot to press “Add Comment”. Congratulations on a hard-win success. Glad you left the black bits in at the top; they “explain” the photo in a necessary way.
