Day 70 - Playing with custom white balance and lighting

My subject was a single red gerbera that a pretty little 4 yr old girl gave me.  She always has something to give me when she sees me - whether it's a "Princess" sticker, or a flower, or a paper cutting that she made herself.  Unfortunately, I never have anything on me that befits that little princess and that's worth offering (I usually see her in the elevator when I am either returning home from work or on my way down to the recycling bins)!  One of these days I must go up to her apartment and I better bring her a nice gift.

Anyway, so here are the experiments with the gerbera that I did over a few hours starting in the evening after it was almost completely dark, and continuing the following morning.

For this image I used my TV as the background, with two low-powered lamps placed at least 6 ft away on either side, aperture priority, f/5.6, ISO 100, spot metering, exposure bias of 1/3 stop.

Natural light at ISO 400, manual, f/5.6, 10s, spot metering

Shot with custom WB, aperture priority, ISO 200, exposure bias of 1/3 stop

90 mm macro lens, aperture priority, pattern metering, ISO 800 (flower was kept in low light), f/5.6

Shot with 90 mm macro lens, custom WB, manual, pattern metering, ISO 100 (flower was in bright ambient light), 1/8s, f/10
