Macramé owls
Curious light source, an energy saving bulb with a colour temperature something between tungsten and neon.
1. In-camera white balance set by showing the camera an Opteka white card. 2. Secondary exposure taken with Opteka grey card in the picture. 3. White balance fine tuning adjustment calculated in Lightroom from the grey card image. 4. Adjustment copied to this picture.
An alternative shot using in-camera Auto White Balance and repeating steps 2, 3 and 4 gave exactly the same end result, but a much larger white balance adjustment was needed in Lightroom.
Daily picture for 11 January 2012 using Pentax-A 50mm f1.7 lens.
