    This is a begginer question, but i have a built in flash with my Canon Rebel XTi, but i want to know what's a big difference between the built in flash and a seperate flash. i know that some go further than others, but my dad has a seperate flash, but he has the Canon Rebel XS or something similar to that, but he says i don't need a seperate flash. so i ask you, what's the big difference?

    A separate flash will have more power and most have the ability to point the flash in different directions, so you can bounce the flash off of the ceiling or walls, which gives a much nicer, less harsh look to your photos.

    This is Nikon centric, but here are examples of bounce flash vs direct flash, this is what convinced me to get a separate flash unit for my camera: http://www.kenrockwell.com/nikon/sb400.htm ..I'm sure canon is similar.

    The next step beyond bounce flash is getting the flash completely off the camera, which is even better, so look into that option also.

    Some bounce flash sample pics over here: http://www.thephotoforum.com/forum/showthread.php?t=113514

    If you just need some daylight fill flash the pop-up can be fine, but that's about it. For portraits and other situations where you're relying on a lot more flash power, getting off-camera flash or just being able to point the flash head in different directions to bounce flash will make a HUGE difference.

    Firstly, a hot-shoe flash sits much higher above the lens...which helps to avoid red-eye and gives a slightly better direction of light.
    As mentioned, the bigger benefit is if you have a flash that can tilt & swivel, so that you can bounce the flash off of a ceiling or wall etc. That will dramatically improve your flash photos.
    The next step is taking the flash off of the camera, which can dramatically improve the light quality again.

    I was considering the SB400 for my D40, but I got to thinking... I have cathedral ceilings and an open floor plan so a lot of my bounce surfaces will be 6'-8' (or more) away. Will the SB400 be powerful enough?

    I don't quite get this. your saying if i take the flash off my camera it "can" dramiticly improve light quality? For the other comments thank you very much, i'm gonna look into buying a rotating flash for my camera for the "bounce" effect.

    I think he means to use the flash remotely (off the camera body itself, but in a differnt location).

    That shouldn't be a problem.

    Absolutely. Well, the light coming from the flash will still be the same, the way it lights your subject will be a dramatic improvement over using the flash from the same direction that the camera is pointed.

    There is a popular site, http://strobist.blogspot.com, site that is totally dedicated to off-camera flash.

    Start with 'Lighting 101'

    After you take the flash off camera, you need to mount it somewhere "else" and control it from camera. :mrgreen:

    That's where Nikon's Commander Mode comes in. It controls and fires the flash and even meters the light at the camera and relays that back to the flash.

    Another option is optical or radio triggers. In this case, you have a 'sender' at the camera and a 'receiver' at the flash. All this does, it tell the flash when to fire and you would need to set the power level yourself.
