    I want to do light graffiti / painting and to do this I assume you have to have the exposure for atleast 30 seconds to have time to paint the light... now I'm in Av mode but I don't know where the exposure setting is? can anyone assist me?
    thank you for reading

    You want to use the Tv mode for "time value". I suggest you read the manual once or twice. ;)

    You can't do it in Av.

    Try Tv and set it to 30 seconds or something (however long you think it will take). You could go to manual mode too.

    You might have to use manual - I don't know if Tv will work if the aperture can't stop down enough to make a 'good' exposure.

    Exposure isn't a setting so much as a combination of settings like Aperture, Shutter Speed and other variables that control how much light gets into the camera and how long the film/sensor is exposed to light...
