Eos 450D Flash query

    Maybe some of the wiser folks here might be able to help me on this. Since I got the 450D 12 months ago it always seems to underperform indoors compared to my Fuji S5000. Drastically so. Either with or without the 430EX the result is the same.

    Subjects OK but background completely dark. I've tried auto (poor); M (with flash popped and shutter speed forced to 1/200) the same; and the best results come from AV with the shutter speed at around 1/50.

    I've compared the results to the EXIF data on the Fuji shots and one which was shot in a pub in almost complete darkness (with excellent results) shows that the Fuji (in auto) decided on F2.8; ISO 200. Obviously my 17-85 lens is only F4.0 minimum and my 50mm 1.4 lens does not zoom, so this can be restrictive.

    The results are so poor in some cases that I'm considering buying another Fuji bridge camera for indoor shots (which are important to me). I don't want to land more money out on another Canon lens. The 450D's outdoor performance in manual mode is stunning.

    All help and advice gratefully appreciated.

    Regards,

    Freddie.

    When using flash, always shoot in manual, your shutter speed controls the amount of ambient light (background in your case) in the shot, aperture controls the flash exposure (subject) and a little bit of ambient. If your backgrounds are too dark for your liking, use a slower shutter speed.

    Thanks for that. The problem with the lower shutter speed cab blur under certain conditions.

    You can make blur more attractive with second curtain sync. The flash will fire at the end of the exposure giving you motion trails. Its not always desirable tho.
