Newbie question regarding HDR.

Just before I take a bracketed set I half press the button to meter and focus. After that with my finger still pressed half on the button do I turn the autofocus off on the lens then take the photographs?

I leave the autofocus on for all my shots, you just have to make sure you either brace yourself and hold very still or better still use a tripod :D
Use 1 RAW and alter the exposure on that.

you could just turn autofocus off before you do all of that?
Autofocus shouldn't refocus for each shot in a autobracket sequence..
I never have a problem with my HDR images from autobracket even if i don't use a tripod.
Photomatix will align the images anyway if you select that option ;)
Hope that helps..
Thanks. Every time I do shots in autobracket mode I turn off the autofocus just incase it tries to refocus between shots.

You generally don't want the focus or exposure readings changing during the bracket so it is best to prevent this in some way. How you do that is camera specific so you might do a google search on exposure bracketing or autobracketing in the Canon 7D. There are plenty of clever people out there who have figured out how to do things optimally for various cameras (beyond what is in the manual).

Contacting pingallery was a good idea. I love her work and have gotten good suggestions from her.
Yes, absolutely shoot your HDR in manual focus. If the focus is slightly different between each image you will get ghosting
Thought so. Just wanted to make sure. Ta. :D

I don't think so - i know that some soft blurs are done digitally in the software - this is just my basic logic regarding all photography, though. Maybe ask Pingallery ? [link] she is very much into HDR and her stuff is to die for gorgeous
Thanks for the link. Just sent here a message. :D
