Question about HDR

When you have to produce 5 or so exposures for HDR do you take 5 different shots on the camera whilst changing the exposure settings, or do you adjust to give 5 exposures from a single RAW image?

And, if it is done by taking 5 different shots, how do you guarantee not slightly moving the camera, on it's tripod, when dialling in each different exposure setting?

5 different exposures using the exposure compensation on the camera, all 1 stop apart.

You need a sturdy tripod and there should be no problem.

Or use exposure bracketing, so that you don't have to touch the camera between exposures.

Thank you. The K100D will only auto bracket a total of 3 images. Is this still the case on better models like the K20?

The K20D does 3 or 5. Multiple in-camera shots is OK for static scenes, useless if anything in the scene is moving. I think that multiple exposures from the same RAW image produces very acceptable results.

Hi Karl I take loads of HDR shot its a technique I like alot. A few pointers.

1) Use Av aperture priority you don't want the camera changing DOF on you by altering the aperture, just the shutter speed.

2) For the same reason after allowing the camera to focus I turn off Auto Focus.

3) Most of mine are hand held if its a bright day for interiors I use a tripod.

4) If using a tripod use a cable release to avoid any shake, and turn off Image Stabilization.

5) Use Photomatix Pro it can deal with slight misalignments quite well and ghosting when things move in your pictures.

6) 3 frames 2 stops apart is my norm, but its best to take spot meter readings and work out how many stops you need and set.

Here are a few examples, some of these are quite old,I really should update this.
