I went to a website today that had some really cool macro photos and I wanted to try the bubbles one that I saw there. My bubbles didn't look all cool and hexagonal like the photo I saw. I pointed a green colored flashlight at the bowl that held my Dawn dish bubbles and took a couple of shots. Here is the one that I ended up with. I was kind of pleased with the final product.
The settings were shutter speed 1/30, F5.6, ISO 40, WB auto, focal length 60mm, no flash used.
The settings were: shutter speed 1/15 secs, aperture F5.6, ISO 400, WB Manual (about 5000K), focal length 60mm.
