Soap Film 41
Some experiments using liquid soap, water - and some honey for the first time - which seems to produce a different effect to my previous efforts. This is a crop of a small area within an 18mm ring ('bubble wand') and a very similar shot is in the Comments. I have blackened out the ugly and distracting plastic surround at the top, leaving the soap film completely untouched.

Lighting by a combination of the office angle-poise lamp I usually use, plus my external flash off to one side - mainly to give a faster shutter speed and smaller aperture in a bid to achieve a greater depth of field (it doesn't make a lot of difference - the liquid varies in thickness so much).
