Weekly commented photo # 39 : The syncline fold and its waterfall

Picture of a waterfall falling along the cliff of a syncline fold
Chapeau de gendarme syncline fold and waterfall

This is the place around Septmoncel about which i wrote a few words one week ago.
Its name means "Policeman's hat" and comes from its shape.

I discovered it in july with ugly weather and pouring rain. The waterfall was very very impressive and i was a little disappointed when i came back in september and found a very low water level despite the rain we had in the weeks before.

I found a kind of little path in the green vegetation you can see under the cliff and made a small serie of images of the entire waterfall plus some closeups i find more interesting.

The photo you can see here was done from the road. I didn't found any other composition to include all the fold with its waterfall.
The light in this end of afternoon was very nice but contrast between highlights on the cliff and shadows in the vegetation was huge. I could have wait a little more but i would have lost the sunrays lighting the rocks.

That's obvioulsy not the kind of images where GND filters give their best results and so i went for the HDR solution.

Five exposures where used.
NEF files where converted to 48 bits TIFs using SilkyPix.
TIF files where blended to a real HDR file with Picturenaut.
A first tonemapped image was then produced with Picturenaut and a second one was done by tonemapping the HDR file with Photomatix.
These two tonemapped files where then blended to give the final image you can see here.

I know that many magazines (and some famous ones) claim that they don't publish composite images including HDR ones. I think that's to avoid too much fakes in the photojournalism world.
I can understand their choice but on the other side when i compare this HDR photo with the best single exposure i've done from this scene i'm forced to recognized that the HDR file has a really better quality ...
