Changing aperture & shutter speed? (Canon)?

hi,

i own a Canon Eos 400D camera, and recently have been trying to get a bit more into photography. unfortunately, i don't know where the manual is, and i'm struggling to work out how to change the aperture %26amp; shutter speed settings on it. can anyone help?

thanks.
Changing aperture %26amp; shutter speed? (Canon)?
In Av (aperture Value) mode the scroller next to the shutter release controls the aperture. The camera will meter for the shutter speed.



In Tv (time value) mode the scroller next to the shutter release controls the shutter speed. The camera will meter for the aperture.



In M (full manual) mode the scroller controls the shutter, if you press the Av button on the rear of the cam and scroll it then controls the aperture.



The meter will not control exposure in Manual mode though the camera will indicate whether it thinks you will over or under expose with your chosen settings, you can choose to ignore or follow the meters advice. With a DSLR you will see instantly if you are way out. Shoot RAW and you can salvage things up to a point if need be.

Next time try reading the manual.

i dont have the same make of camera as you but if there is a dial thing on it then you have to change that to the shutter speed mode (s) or aperture (a) then you rotate the other dial-the one without any writing on it near the shutter button-and it will change the shutter speed or aperture of whatever. hope this helped :D
Hey,



Here's a post called 'Photography Tutorials' - http://the-digital-photographer.blogspot鈥?/a>



It talks about shutter speed, aperture, ISO, Camera Modes and more.
They have the manuals on line at http://www.canoneos.com
Not a good idea to lose manuals to electronic gear. They have very useful info. Consider setting up a file for the documentation to your various gadgets. You'll be glad you did!



Luckily you can retrieve manuals for cameras from the manufacturers' %26quot;support%26quot; pages on their websites and from sites like Retrevo:

Good luck tapping the features of your camera!
Right there are three modes which you need to know about.



Tv - You control the shutter speed. Camera determines the aperture

Av - Controls the aperture. Autoexposure sets the shutter speed.



In these two modes you the button labelled +/- on the back of the camera adjusts exposure compensation. Also there should be a function of Saftety Shift which automatically change the settings if the autoexposure system finds that it can't get a suitable exposure from the shutter speed or aperture you want to use.



For example if you're shooting in Av mode using f/2 ISO400 on a sunny day, your shutter speed will end up being faster than 1/4000. Saftety shift will automatically adjust the aperture so that the image isn't overexposed.



Then there is M mode. This is manual mode, my favourite because I find that the AE system frequently is a bit dim witted. This gives you control over both the shutter speed and aperture. The dial controls the shutter speed and the +/- button with the dial controls the aperture.
