 Post subject: High Dynamic Range (HDR)
PostPosted: Thu Apr 05, 2012 7:59 am 
Hi In the case of taking pictures for HDR would 1/3 bracketing steps with three exposures
be satisfactory for good results . Or do I need to do bigger steps + more exposures :?:
what would you suggest ? regards drecked

Depends on the content of your image. If you have a really bright sky with really dark areas in other part of the image then you will need a wider range of exposure. If you have a smaller range of exposure to cover, essentially to avoid burn out at the light end and being able to see detail at the dark end, then you don't need such a broad range.

It also depends what effect you are going for in terms of subtle or obvious HDR.

usually a 1 stop range between exposures is required, with a two stop range being preferred. This is pretty well the norm in all circumstances.

You in the end have to be the judge, of the dynamic range in each situation that is required. But since effective HDR photos usually have a very broad dynamic range, again 2 stops of exposure range between each shot, is to be preferred.

+1, I was shooting a monument against a bright sky in Ottawa a few weeks ago, I shot in 1 stop intervals to get the detail of the statue, and the original detail of the sky. You also have to consider how long your overexposed exposure is, as you do risk getting motion blur if it's too long (trust me, it makes a pretty noticeable effect even after combining the images).

im still experimenting with HDR techniques but one thing i have noticed is that its a good idea to turn off the IS function on lenses when taking the shots as the lenses still try to stabilise even when on a tri pod and this lends itself to minor shudders in the images on longer exposures.
