what I did (so I can remember!!) -
- Manual mode 1/250 sec f 5.6 iso 100; camera 60 cm *directly* over the surface of water. Spend some time getting the plane of the lens exactly parallel to the surface of the water.
- 100 mm macro lens manual pre-focus on the meniscus of a knife or chopstick placed in the vase.
- I used a flat bottomed glass vase filled with about 8 cm water (to blur the background).
- water surface was about 40 cm above the background.
- off camera flash aimed at the background @ 1/16 power, placed 30 cm from background
- use the smallest amount of detergent possible (less than a drop) & only stir very gently in one direction to avoid excess air bubbles
- make sure the glass is really clean & detergent free before you start
Once I had the camera and flash set up, I changed the backgrounds and found different effects with different patterns & surface textures. I liked this one - a sari my son gave me for Christmas. The colours are refraction from the colours of the striped sari fabric, not a fancy PS trick.
Yay -- one more off my photographic bucket list! :))
If you have time, view enlarged on black for the full astrological viewing experience!! LOL
