Canon Rebel XTi- how do I take multiple exposures on a single frame?

Answer 1

You can't, it's a digital camera.

Answer 2

Set the camera to take 'Raw' photo under image quality menu.

From a raw photo, you can create multiple exposures and save them as new copy. Usually, a raw photo captures enough detail that you can go 2 full stop in either direction. You can save the newly exposed photo as JPG or any other format you like.

Once you have multiple photo as different exposures, you can go one step further by combing them back into one photo. This is called HDR (High Dynamic Range), and can easily be done by Adobe Photoshop. (File -> Automate -> HDR).

Besides Photoshop, you can also use "PhotoMatrix Pro" to achive a HDR photo.

The entirely other solution is to use what traditional film photographers have done for years. Use bracket and take multiple shots. With cheaper but larger in capacity memory cards, there is no reason for not to use bracket. Canon Digital XTi along with most other digital camera has bracket features.

Answer 3

No way man. that other thing is wrong. the Best way to do it is with Stroboscopic photography.

You set the camera to long exposure of 3 secs or more. you have a strobe light trained on the subject (in a darkened area, with black background) and the flickering strobe will illuminate the subject in different places on the same photo.

Answer 4

yes you have to shoot in RAW mode you can't do it otherwise. As far as HDR you can use CS2 or Photomatix Pro! not Photomatrix. Doesn't always work with modified exposures in RAW
