The perfectly poured pint – rendered green fluorescent. The green fluorescent appeal may be partly related to professional interests (related image). The high contrast particularly emphasized the bubble fine structure in Guinness.
Original image (because on a very very cold winter day, inside seemed the best locale for the day’s photo):

Guinness as a moonscape – craters, pocked surface ridges, crescent. I really liked the ultrafine structure of the bubbles (seen on magnification) and the shadow cast by the legs (I needed a taste for complete photographic inspiration!) as well as the shadows produced by the daylight coming from the window.
These aspects (especially the bubble microstructure) are emphasized in the black and white version of the image:

Though I think the sepia-toned version is the most true to the beer (and indeed the best of these images, taking into account shadows and wood grain):

If your Guinness doesn’t look like this (and it usually doesn’t), find a different bar where they know how to properly pour a pint!
Cheers!
