Of
course movement (ghosting) in your HDRs sucks. It is
just no good if the viewer thinks "That is really not
okay". But sometimes movement is wanted and sometimes
you might find creative use of movement in your HDRs.
Photomatix can help - but you make it all happen.
Movement is not always about the elements in your
images. Movement can just as well be you and your camera
moving. Look at the picture below. I am standing in a
small dinghy as we are passing a low bridge in the
central part of Copenhagen.
I
wanted to keep the movement of me and the camera; but I
did not want the blue tourist boat to show any
movement - even it was sailing.
I took
three pictures for this image. I wanted to keep a fast
shuttertime for the normal exposure (0 picture) to make
sure I could avoid movment in the tourist boat. Three
pictures has a faster combined shuttertime than five
pictures would have. I did furthermore settle with only
one EV-step between each picture - again to keep the
shuttertime short. But remember: The shuttertime for the
+ 1 EV pictures is long enough to ensure movement in the
dark areas of the image (under the bridge).
I did
not turn up ISO. It would have provided faster
shuttertimes for sure; but I still needed the movement
in the dark areas.....
I
gained a lot of movement in the dark areas of the image
and I avoided movement in the bright areas. To ensure it
stayed that way, I used "selective deghosting" in
Photomatix - not "automatic deghosting". I made a mask
covering the view outside the tunnel and the reflection
of the opening in the water. Deghosting was only made in
that mask. |
