OCA Course: Tungsten and Fluorescent Lighting

Tungsten: Sitting room and patio. At ISO 100 the light levels in the room and outside gave an exposure of 0.4sec @F4, so no hand holding.

                                          1. White balance on Auto.

                                          2. White balance on Daylight.

                                          3. White balance on Tungsten.

The difference between auto and daylight WB is minimal, as the auto setting does a good job of equating the scene to daylight at the expense of very yellow tungsten lighting. On the tungsten setting, the room looks relatively normal, but outside is cold and blue.

Fluorescent: Utility room and window. Again, at ISO 100, 0.8sec @F4 meant a tripod was essential. 

                                          1. White balance on Auto.

                                          2. White balance on Fluorescent.

The auto setting gives some warmth, but is too yellow. The fluoro setting is nearer the correct appearance but looks a bit grungy, and isn't a true match. Perhaps it is a bit green.


O.K. - that's quite enough of white balance. I don't use small fluorescent bulbs on principle because of the pollution caused by those countries who mine the chemicals to make them - just like batteries for electric cars, so I'm not doing any more images for this exercise. Long live petrolheads.

My God, that was a boring exercise!
