White Balance

Finished the cardboard box light tent. Joanne suggested we just wrap the muslin on all three sides with a single strip of cloth. That worked better than three separate squares.

Set it up and adjusted the clip on lamp. Then shot off some pictures of my small test subjects. They looked ok in the LCD.

They didn’t look ok when I moved them to the computer. They were red/brown like my earlier ones, using a high intensity desk lamp. Seems like the Reveal bulbs may not be as full spectrum as I thought. Back to the internet.

I knew I would, sooner or later, have to address color temperature. There wasn’t total agreement on the web concerning the reveal bulbs. Other than it is close to an incandescent and it filters out the yellow.

Took out the manual and figured out how to create a custom setting. This would be the technique for using a white or gray card. The light tent has White Bristol Board for a floor and walls. I pointed into the empty box as the white reference. Camera thinks it is 3000K. That’s pretty close to the internet findings. I went with that.

The second test shots cured the red/brown problem. But the figures seem darker.

It looks like I need more of the same light. And I may have to mess with the exposures.
