Setting different exposures for HDR

Hi guys

I was wondering how I would set different exposures on my D90 to use for HDR pics.

I took a sample pic this morning & used the bracketing function on the camera. This is 1 normally exposed, 1 over & 1 under. So 3 shots in total.

I understand you can have loads of the same pic at different exposures so what is the best way to do this?

I have a funny feeling its a simple answer & im going to feel like a :geek: when I hear.

Any help appreciated :thumbs:
 
Hi,

I suppose the simplest way would be to set your camera up on a tripod, set it to manual, take your first shot then adjust the shutter speed (shorter for under exposure, longer for over).

If you had the camera set to shutter priority then the aperture would automatically change to achieve the correct exposure, something you do not want to happen in this case!

Oh, probably best to set the ISO too.

I reckon 5 shots would be plenty. Although some one maybe along shortly to give more first hand advice. :thumbs:
 
Hi, what you need to do is go to the menu and find "auto exposure bracketing". On canon, it's AEB. You'll then get a chance to shift some little dots either side of the middle and this is your three exposures. I usually go for -2, 0 , +2 but my camera only does 3 anyway. 5 is good too (-2,-1,0,1,2).

if you're on a tripod and set to continuous shooting, you only have to press and hold the shutter down once and it will take all three/five shots at once. Better still, get a remote shutter release to minimise camera shake.

and as Paul says, ALWAYS shoot in Av mode to eliminate DOF discrepancies between shots, as this would cause blurring when you layer them up.
 
Cheers guys, thank you for the help, will give that a read tomorrow - much appreciated!
 
You can only take a maximum of three images with exposure bracketing on the D90. I've tried it using +2,0,-2 exposures. once you set up bracketing have it in fastest shoot mode and press and hold shutter button. It then takes three shots and stops. If you need more shots you will have to adjust the exposures manually.
