Christopher, what were you thinking?
« on: July 11, 2011, 02:47:46 pm »

HDR
Crooked horizons
Branches coming in from the sides

Are you a masochist?

There's no larger version of the image available.

Or have I been trolled?

"If this had been shot with one capture, either the highlights would have been blown out, or the shadows would have blocked" Christopher said in the article.

What kind of blockage is Christopher talking about? what is a blocked shadow?. After reading the entire article, I see no mention of digital noise, the one and only reason to shoot more than once when doing HDR photography. If shooting once you can preserve the highlights at the same time you get an acceptable level of noise in the shadows, you got it right. There is no point to shoot more.

Bracketing has no magical effects in the final result beyond the degree of visible noise. In fact if bracketing is not needed for noise reasons, it becomes undesirable and tiring (more effort, more time, more memory and CPU resources, ghosting issues,... in brief more limitations).

There is nothing you can get from a bracketed series of pictures, that you cannot get from a single shot as long as it contains detail in the highlights and acceptable noise in the shadows. I'd bet some of the scenes in the article didn't require any bracketing.

There is also no point in bracketing less than 2EV or 3EV apart, the contribution of additional shots is null. Finally, the less noisy sensors become, the less reasons remain for bracketing.

Regards

When I posted this thread it was in reaction to the photographs that Christopher had in his article. I had an instant dislike for the first image and that rarely happens. I generally am more indifferent if anything.

I asked myself what it was about the first image that I disliked and the answer came as quickly as my dislike. It was the composition, it had failed on three levels.

There are three types of composition that you can have; symmetrical, asymmetrical and symmetrical disturbed by asymmetry. The first image was an example of symmetrical disturbed by asymmetry. We all like symmetry and our eye is directed to what disturbs the symmetry. That becomes the focus of our attention. If it had been one of Rob's models I might have had a different reaction.



The two things that disturbed the symmetry were the crooked horizon line and the branches on the left. They were now the focus of my attention.

The trouble was furthered in that if you removed the distractions as in the second diagram the composition is still a fail. We have a very ordinary tree plopped in the middle of a paved area.

The thread Do you hate HDR too? has been read 126631 times so I know it is a hot topic.

Seeing the third image was so similar to the first I couldn't read the article and I posted this thread.

I would have been happy to let the thread fade into the distance but Guillermo added to it.

I'll create a new thread so that people can read his comments as I'm sure this thread would normally be ignored by now.

The thread is here.
