Soap Film 38
One of two soap films from last night and a different effect from my previous ones. Usually I go for the colourful patterns which form quite quickly. This one is after most of the soap becomes discoloured and drops to the bottom of the ring, just before it bursts. I have coloured it in Photoshop from the original grey otherwise it is exactly as seen.
I used a mixture of washing up liquid and water.
