15/52 - Hard Disk

One of my friends at work had a whole bunch of old hard disks on his desk so I thought I'd use one for this weeks photograph. The disk was from a laptop and therefore fairly small in size. I used the 50mm f\1.8 lens to shoot this as I was initially going for a very shallow depth of field. As it turned out, I changed my mind and shot at f\8 but still used the same lens.

This again was a 2 light setup but instead of using a snoot I opted for a home made grid spots. Grid spots are very similar to snoots but it is used to light only a very small area of the subject. See image below for an idea of how you can control light using a grid spot.

I used the Canon 580 EX II fired from camera left, at 1/32 through a CTB gel and bounced the light onto the hard disk using a white foam-core board placed on the right of camera. I changed the white balance to tungsten to enhance the blur light.

I fired a Canon 430 EX II from high camera right, through a grid spot and CTO gel at 1/2 power, aimed at the top corner of the hard disk. I used the CTO gel to compensate for the tungsten white balance setting on the camera.

The effect of the grid spot can be seen in the image below.

If I had used a snoot for this shot, the entire hard disk would have been lit up by the 430 EX II and I would have been unable to get the blue "feel" which I was after.
