Hello! After a short holiday “Notes” with you again! He took a small pause, rest, gain strength, looked at football … By treating thousands of photos from vacation in St. Pete, I found myself thinking, “but what for, I use bracketing?” Shooting is bracketed at least three drawbacks:
Three times increases the amount of footage that is occupied on a flash drive (and hard disk space) place.
Three times the camera is reduced resource that is important for amateur SLR.
Increases processing time pictures – because you want to see more pictures, pick out the best.
I posted in twitter this subversive idea, and Artem caught, they say , “Do not bracket and fit under ETTR. I usually leave 2-3 pull down. ”
Well, I decided to read about then ETTR and allow for a question with exposition. As it turned out, the theme of something very important, affecting the foundations of photography, but it really is talking about very little. In fact, in RuNet dozen articles are not typed.
ETTR – shooting method in which the exposure is adjusted to the details in the highlights have been worked out as the ultimate image histogram was shifted to the right, but not to drop in at the right edge, ie loss in the highlights that were not.
We turn first to those who have already expressed my opinion about ETTR:
Even in 2006, translated and supplemented GribNick article Michael Reichmann – Expose (to the) Right (Luminous-Landscape.com) and Ron Bigelow – Digital ExposureRonbigelow.com ). Based on theoretical calculations, the authors concluded that the maximum space allocated to store information about the light areas of the picture and take a picture if one is a little lighter, we get more material for processing, thus less noise and more detail and the final image after processing will be better. In theory, all right, but there were people who decided to challenge it with both theoretical and practical point of view.
To quote the authors of http://www.libraw.su/node/45 are against ETTR – “We can say that compared to ETTR we have (in the case of normal shooting – my note.) redistribution in favor of the dynamic range of good detail in the middle colors and low noise in the shadows – some sacrificing the extreme values of lights, to the details in which the human eye is still unresponsive, and the necessary tonal gradations are easily reduced by retouching, substantially less demanding than the noise reduction in shadows and midtones. We note here that the underexposure midtones greatly complicates the procedure and sharpen. »
Anatoly Skoblov is also a supporter of ETTR . ” So, you know, good exposure – this is a “mega-ETTR» or «good ETTR», according to the story (not all are suitable for a “mega”) and the strength of your nerves. Frame a bit lighter – a marriage (marred the right) is darker – you lose shadow detail and overall quality across the frame. The only justification for a lower exposure (darker frames) – Specific requirements for the shooting. For example, ETTR can give you a very slow shutter speed and it will not work. There is nothing to do and have to remove the dark. ”
Separate paragraph will tell about Eugene Timasheff and his way of handling – “As I have written repeatedly, during the shooting I do not use gradient filters, and shoot some bracketed images and collect the finished photograph gradient mask on the computer. I usually rented a bracketing mode: 0, -2, 2. ” Looking at Eugene’s blog – seems to be a single word about ETTR.
Add that to me personally? ETTR, like most of the techniques / methods in the photo, is not universal and should apply in the circumstances. For some subjects – ETTR gives a gain in quality, for others – a win is questionable.
In his own collection, I found a photo which was taken just on the principles of ETTR and here’s what happened.
Shot, shot c ETTR, treated
In this story, I did not notice the difference in specific, although the settings used are different. No longer had to bring ETTR sky.
I think the main thing that was correct exposure, shadows and light from failing. If you do not have the range of the matrix – bracketing, but bracketing the mind to the correction of plus light failing. But not so – set up bracketing + / – 2 and snap the entire vacation.
Well ETTR – for those who understand the essence of the theory and has a good post-processing programs Finally just a photo of sunset:
