I saw a Facebook post on group site I participate in about refraction of light. The images were very interesting. I decided to put together a few items for our camera club to use at a future meeting.
If you google refraction of light you come back with a lot of scientific information. However when you google refraction of light in photography a lot of nice images appear!
With help from a friend of mine, I put together several backgrounds; some had color some were black and white. I purchased scrapbooking paper and used double stick tape and old scrap mats to mount the paper to so they would not bend.
Using a pole lamp with 3 lights to light my subject, I put up my backgrounds and filling glasses with water. I also laid some of the backgrounds flat and used them as a base; the patterns then reflected on top of the water.
My camera settings (Nikon D800E) ISO 640, f/14 – 16, shutter speed ranged from 1/5, 1/3, 1/13 sec depending on which background was being used.
This is a fun winter project as you do not need a lot of supplies, just clear glasses, vases, bowls, water (distilled is recommended because tap water bubbles), and paper or fabric with a design. You can make your own designs using Photoshop and printing the off of you printer.
Have fun experimenting!
