Why is exposure with my Canon flash system so unpredictable?
Digital Photography FAQRecent Canon SLRs use a system called E-TTL to determine flash exposure. (Newer models use E-TTL II, which seems to be more robust.) E-TTL is praised by some for allowing very precise control over flash exposure when used properly, but it is slammed by others for being too sensitive to very small changes in the center of the image and requiring too much planning to get proper "automatic" exposure. There is probably some truth in both positions.
Related QuestionsWhy doesn't Canon use distance information for flash exposure calculations?
Canon EOS FAQ 2.4 - FlashDistance info is only useful so that the camera can apply the "guide number" formula: f-stop = GN/distance. This is only a rough approximation. Off-The-Film (OTF) metering measures the true exposure of the film, which is much more accurate than the guide number calculations. In A-TTL, Canon uses a preflash to actively judge the effective flash-to-subject distance rather than passively.
Related QuestionsWhy do I get such long exposure times when using the flash in aperture priority mode?
Digital Photography FAQWith many cameras, the camera assumes that you are using fill flash in aperture priority mode. Thus, it picks the correct exposure for the available light and fires the flash merely to fill in shadow areas. On some cameras, you may have workarounds for this: In manual mode, some cameras (e.g. Canon SLRs) will increase flash power to provide light needed for proper exposure, up to the limits of the power of your flash.

How can exposure be controlled with a studio flash system?
Konica Minolta FAx (Forum & Ax FAQ)The Ax can synch to the flash at any speed; however, if you set the shutter speed faster than about 1/800s, the exposure will be reduced because the camera is not capturing all of the flash duration. This can be used to advantage to allow you to open the aperture up wider than would otherwise be possible, but avoid overexposure by using a very high shutter speed. The open aperture provides a short depth of field which is often desirable in portrait work.
Related QuestionsWhat is flash exposure compensation (FEC)?
Digital Imaging - dslreports.comFlash compensation is simply the adjustment of the intensity of the flash burst. Flash compensation is used when your flash is putting out too little or too much light. Many sub-dSLR cameras do not offer this option. Say you are shooting a group of people in black suits. Your flash fires and it turns out that your photograph is too dark. You didn't get enough light coming from the flash.

Related QuestionsIs the A-TTL program affected by flash exposure compensation?
Canon EOS FAQ 2.4 - FlashIn fiddling with my 430EZ, it seems as though it doesn't figure the exposure compensation into the selected aperture. If you say you want flash overexposure by 3 stops, it gives the same aperture as selecting flash underexposure by 3 stops. Note that in a TTL (or A-TTL) flash system auto flash exposure is changed by changing the flash duration at a fixed apertures. Thus you would not expect an aperture change.

Canon is still canon but of course your characters are allowed to try and change their future.
