Best approach
 
Here's an original pic direct from the camera (resized). Below it are 7 examples of various approaches to enhancement ...

HDR from multiple images
HDR from single image using Martin Sykes' program
Exposure blending
Edited exposure blending
Single image manipulated in Sagelight RAW editor

Any guesses as to which is which ?
Which do you prefer ?

Here's the RAW if anyone would like to have a play with it:

as is usual a combined approach usually works best.

photoshop and cs4

could have been better with more than just 1 raw too.

Very nice but the RAW still has a lot more detail in the trees, particularly in the background that could be brought out.

I know what you mean about the foreground bush but is does actually seem quite bright for some reason, despite there being no light source in the foreground.

Here's the + and - 3 EV jpgs (RAWs getting a bit big) for anyone who would like to try an HDR ... no halos please ;)

Hards80, did you do something with original picture, or is this picture with your comments from one of the above, but only larger... cause, this photo is absolutely remarkable for what details and colour I can see and appreciate... compared to the initial photos. Was just wondering where this photo came from. It is very well done.

Many thanks and all the best.

yea, i could have brought out more detail in the background if i chose, but i felt this struck the best balance between detail and reality. that is just my feelings though, others may have wanted more detail.

Ned, this is my conversion, not one linked, i worked with the RAW file he linked. basically it is just the photomatix pseudo-hdr blended back with a RAW converted image. i erred on the side of keeping it natural with this scene. or at least that was my intentions, whether or not i succeeded may depend on the viewer.

I'd also like to see others' attempts at HDR for the scene, using the 3 files I've uploaded ... -3, 0, +3 EV. HDR is used to bring out detail ... which can probably be done just as well, or better(?), using the single RAW.

My feeling is that with scenes such as this, which has quite a high dynamic range, there's not much benefit in HDR. I'd love for someone to show me otherwise.

I'd also like anyone to show that HDR is better (?) than exposure fusion (exposure blending) using these files.

Simple,

The third file, 0 EV, is the RAW
http://uploader.polorix.net//files/1585/P1000186.RW2

I can upload the JPG if you don't have a converter.

I think Hards80 version from the single RAW looks better, although the intermediate file above might help. Both yours and Hards80 are starting to show a halo above the trees. Most of my versions, using various approaches also show halos, except for the 3rd edited version.

Hards80 Mar 4, 2010 7:35 PM

for whatever reason amcam, for me, your original had some halo above the trees.
