This is for the WordPress Weekly Photo Challenge of Purple. I hate posting the same old thing, and trying to find unique and creative ways to do things is just one thing I love about photography. The photo above happens to also serve as my Project 365 photo for Day 243, getting closer and closer to that 300 day mark. If you are wondering how I did this, great, because it’s not that hard, but does take some patience and a bit of prep work. Every time I do this kind of photography it always turns out different, which makes it a unique technique to try.

The image above, and the other below, are simply a mixing of ordinary cooking oil, and tap water, placed together in a glass cooking bowl or cake pan. Making the colors is the fun part, you can be creative here, use food coloring, fabrics, a colored bowl, or like I did here, just different colors of copy paper. Here I used two yellow and two purple pieces of paper off-set with each other where they all came together in the center. That is how you get that the bubbles with a mix of different colors. To use paper, you just place is under a clear glass bowl, to use food coloring, just place a white piece of paper under a clear bowl.

The hard part is getting the focus to work because there are several different focal points, like the bottom of the bowl, the water, the bubbles, and paper under the bowl and so on. In this case, I used a Nikon D7000 camera body, a Nikkor 50mm f/1.4 lens, mounted on a Nikon PK-13 (27.5mm) extension tube (extension tubes are really cheap if you have a DSLR). Using an extension tube is a way to do macro photography without having to buy an expensive macro lens. If you try to use an extension tube, just keep in mind the lens will have no aperture value, especially if you are using a newer lens with no aperture ring. You will only have the ability to change the shutter speed to gain the proper exposure, and the focus will be very very narrow.

I will say that purple is one of the most difficult colors to shoot photographically in the digital age. The color tone always wants to shift blue, so getting a true purple is actually very difficult. I did try this out last year, and got totally different results, but you can see those at Testing the Oil and Water Theory Close Up. So this is my interpretation of “purple” for this week. See you here again next week with whatever the theme happens to be next week.
