Figure/doll photography 121 – How to produce white background

This is another one of my figure/doll photography 121 post. A few months ago, I’ve posted an article on how to produce a true black background without the use of any black background material and/or image editing software. I wrote about the black background because I find most people does not know how light works its magic in a photography sense. The people I talk to tends to instinctively come to the conclusion that if a photo’s background is black, then there must be something black behind it. If you have read my article, then you would see that a true black background actually resulted from a lack of light coming towards to your camera. Today I want to look at the opposite side of the gray scale — how to produce a white background?

Well again a lot of people instinctively think that a white background is the result of placing some kind of white material behind the subject. Below is a photo that I took in front of a white fabric backdrop. However, when compared to the white frame that borders the picture, you can clearly see that the actual background is not 100% white. In fact if you load it into an image editing software, you will see that the background is somewhere between 96% – 92% on the gray scale. On the gray scale there’s only one white point which is at the very end of the gray scale. Anything that’s not 100% on the gray scale, or 255, 255, 255 in RGB value is not pure white. And 255, 255, 255 RGB value is what the background must be if we were to call it a true white background. Anything less is just a different shades of gray.

Star gazing with Canon EOS 7D

Last night the sky was clear with no cloud coverages. My friend and I drove to a farm near Pickering and did some star gazing. I brought my camera gears along to do some simple astrophotography.

First easy target for the camera is the moon. I’ve posted my photo of the first full moon of year 2010 before. Beautiful as the full moon is, it is actually too bright and does not have enough contrast on the moon surface to see some of the craters. A new moon will actually offer much better details than a full moon because of the contrast provided by the shadows on the moon’s surface. Last night is 2 day past moon’s first quarter, the moon is actually about 57% full. However it still offered enough shadows on the moon’s surface so that some more details can be seen.

The same gear as the last moon shot was used. Canon EOS 7D was coupled with Sigma 100-300 F4 & Sigma 1.4x teleconverter all sitting on the Manfrotto 055 Pro tripod. This gives me a relative stable platform for the camera and an equivalent focal length of 672mm. The following photo was shot at ISO 100, F11 @ 1/100th second.

Yorkville Exotics

Went to Yorkville Exotics Car Show today. This is a new car show that started this year in the downtown heart of Toronto. I got a bit restless waiting for my new car to come from Halifax so I wanted to go there to check out the other exotics before my exotics arrives. The show is primarily sponsored by Ferrari and Porsche so the car that’s on the show is also only Ferraris and Porsches. Since I was just dropping by quickly during noon time, the lighting will be horrible, and I’m not going to spend too long at the show, I only brought my point and shoot. So unfortunately the photos are all pretty bad to my standard.

But anyway here goes.
