This entry is for the Macro Group – reposted as a journal entry
Just some info in case anyone is interested in knowing how my Red Bubbles image was taken.
Lens – a 90mm macro with 12mm, 20mm and 36mm Kenko tubes attached.
The bubbles are actually very small and colourless. Just plain water in a wine glass with a little detergent added. At that magnification every little scratch will show so best to use a new glass if possible.
A piece of blue poster card was placed behind the glass with diffused light from a bedside lamp shining towards it.
A piece of red poster card was placed under the glass with an overhead light shining down on it causing the red to be reflected up onto the bubbles.
f11 (3 kenko tubes = very narrow DOF)
mirror lock up
Then take about 1000 shots, toss out the badies and keep a couple :o)
Looking forward to being part of this group and seeing all your great macros.

Than ks for the expmlanation. Very interesting.

Many thanks kathy
Thanks for the info!! What is a kenko tube? Is it similar to an extension tube?

Thanks everyone, I hope the info will be helpful for your own experiments.
Derid – yes, Kenko’s are extension tubes, they come in a set of three sizes. I don’t usually use all three together because of the very narrow DOF that causes but in this case I did , as I only wanted focus where the bubbles hit the glass anyway.
