| I’m wondering if anyone has some insight on a slightly technical question. I was reading a lighting tutorial about a technique called “dragging the shutter” when shooting outdoors using a flash in a low light situation. The tutorial explained that a TTL flash unit will use flash based on the aperture and ISO combination of your camera only and that by adjusting the shutter speed of your camera you can achieve a much better exposure by allowing more time for the ambient light to come in. An example was shown of a guy standing against a street light at dusk in front of a building. In one shot (1/60th second exposure) the man was lit well but the building he was standing in front of was nearly black. The flash lit up the subject but the shutter speed was too fast to allow enough light to capture the building behind him. In the second shot the photographer “dragged the shutter” (1/15th second exposure) and now the man was very well lit AND the building in the background was well lit. I understand the concept here. The slower shutter speed allowed more ambient light in which allowed exposure of the building in the back. But now comes the technical question. I believe my Sony A100 has built in light metering for both spot metering and wide metering where it takes the whole frame and averages the light. If I shoot a flash in program mode with wide area metering on should the camera take into consideration the shutter speed it needs to correctly capture the wall behind the subject or will I need to be in full manual mode, find out what the camera thinks the shutter speed should be and then adjust it down from there to compensate? |

I should think so, all the Nikon's do it and I'm sure all other modern SLRs do too. |

| I just took a look at the specs for the Sony and it does perform "Fill Flash". :-) |
