I am getting into HDR and trying to take bracketed shots. However when I upload them onto the computer they are ever so slightly out of alignment give soft images. I have made sure the tripod is tight etc..

I have tried to use mirror lock-up but it does not work for bracketed shots. It does work for single shots. I have a 40D can anyone offer any words of wisdom?

Thanks

It's time to use a remote/5 second delay timer.

Sometimes all it takes to knock your shots out of alignment is a small breeze. I know you said you've tightened your tripod - but just make sure your camera strap (if you've got one) is not flapping against the camera/tripod in the wind. I find the 10-second timer really useful on the 40D (given that I don't have a remote timer). I don't use mirror lock-up on my shots - I just shoot 3 bracketed shots as normal, and this seems to work okay.

What software do you use? Sometimes this can make a difference. I use Photomatix Pro. Also, I find that I get better (sharper) images in Photomatix Pro when I work with TIFF files.

If you use Live View when on a tripod the mirror is already locked up. Put it in x10 magnified view and any movement becomes very visible. In addition I use a cheap wireless remote release, about $20 on Ebay, to avoid any contact with the camera. And to increase the stability of your tripod hang a weight from it.

Board member Team Speed was selling wireless remotes at one time. I don't know if he still does, but you could PM him.

As mentioned... go into Liveview... that locks the mirror up. Just one button to press. Also use a wireless remote. Try looking through the viewfinder and trip the shutter manually....you'll see all kinds of shake.


Bohdan - I may be, and probably am, completely wrong.

You can use SW like Dynamic HDR that let's you manually align the stack too.
