Big Bubble Rainbow

I held a big bubble in front of a fluorescent bulb here. I love the range of colours. It's like a colour palette. There's no editing here. I just cropped and turned the image. No saturation or contrast edits!

 

Exposure can be difficult though. If you try this yourself, try manual settings.

 

Oh, and it's a macro shot. You can find the EXIF data up in 'actions' - above left.
