If you mean timed shutter release and not remote or cable
release, then your Rebel has that. I have the earlier Rebel XT
and there's a control on the back of the body that runs through
single, multiple, and time exposures. Just find it, manual in
hand would help, change it to timed, then press the shuter down
and jump into the picture.
But, if you're talking about being able to hide in the bushes and
trigger the shutter to catch animal or bird life in the field of
view of your camera, I do not have any info that will help you.
Sorry.
Incidently, an old-fashioned cable release like I have for my
still working 1969 Nikon FTN, was simply something that attached
to the shutter button - I think mine threaded on - and it's
purpose was so that you could put the camera on a tripod, line up
the shot in the viewfinder, set up any lights or reflecting
umbrellas, whatever, then step aside and gently push the cable
button. The idea was to NOT shake or even minutely move the
camera when it is on a long or even multi-second exposure.
I DID use my cable release, but more often when using the camera
on a copy stand to copy slides or photos at close focus ranges,
rather than a tripod shot in the mountains. Perhaps the simple
Rebel timed exposure will help you.
