Are you trying to merge images already taken at different exposures? What exactly are you having an issue with?

 

Can I use the same picture but with different contrasts?

and yes to merge the pictures together

 

No three different pictures with different exposures must be used.

 

You can, but it's not considered true HDR.

Are you using Photomatix to merge the images?

 

I am using a Canon Rebel XSi... How do i do different exposures

 

That's something that you'll have to look up in your camera manual.

 

Im using PhotoShop CS3

 

on my nikon d60 you... actually nikon and canon are much different...... but i would like to know how to do this aswell! (HDR not change exposure haha)

 

many different ways. best way though is go into the menu and look for bracket. 3 photos is enough but the more exposure the merrier.

Use a tripod(or something to hold the camera still, it must not move between exposures) and take the pictures, it will automatically change the exposures between each time you press the shutter release.
