![]() So this pic wasn't taken by a DSLR but by a compact. Flash has been fired but the background appears dark/underexposed. In any case,the background shouldn't have appear to be dark as the place was actually pretty well lit with tungsten lightings. why is the background so dam dark and it seems like every pic my friends and i took had dark backgrounds. Is this the limitation of a compact? any compact experts willing to comment? |

short flash range and high shutter speed?

i think it's the limited range of the flash..
FYI it does happen to DSLR as well not only compacts..

i suppose the compact camera reading wanted to achieve a faster shutter speed, pushing it to a faster speed when using the flash. as a result like what a dslr will achieve as well, a lit subject but without ambient lighting. when shooting indoors with compact what i will do is to use slow sync flash, works most of the time but still subjected to handshake blur where you get the curtain flash motion blur and sharp effect.
btw is the guy in red clarence? |

It's not really the short range of the flash, it is a law of physics - the inverse square law that dictates how light falls off (at 2x the distance, you get 1/4 of the light and so on). So when you use flash, the flash sends a brief, intense burst of light, which lights up the people more than the background. When people are properly exposed, background is not. If there is sufficient light in the store, try not using flash.
Even if you have a very powerful light source on your camera pointing at subject, you will still have the problem, unless: 1. You are far enough from the people that the difference in distance between camera - people and camera - background is negligible. This is not usually practical - and then you will have a separate problem, shadows in the background. 2. Use external flash and bounce light off ceiling / wall. 3. Use additional flash to illuminate background. 4. Use high ISO and turn down / off flash output. Night mode may work - I don't have a lot of experience with that. Flash is not easy to master. Proper lighting may be one of the most difficult technical aspects in photography. |

![]() Another misperception is the intensity of light. "Pretty well lit" is just a human impression but the real intensity (what the metering system will capture) is a different thing. You can try this with your cam if you have a proper display of aperture / shutter speed. Switch off the flash, set the cam to a fixed aperture (e.g. 5.6) and try to take pictures indoors in various buildings (home, office, restaurant, shopping mall etc.). The readings of shutter speed as the camera sets it will fluctuate although you might say that it all looks "well lit" to you. Secondly, human eyes adapt to different light conditions (so that we can see properly), the camera's "eye" doesn't - it always measures the real amount of photons coming in. That's why we need to take care of shutter speed, aperture, ISO settings etc. |
