There have been a flurry of statements recently on photo fora that exposure to the right (ETTR) is an obsolete concept. The argument goes that, while it may have been useful in the past, modern cameras have so little noise that ETTR is currently a waste of time and brain cells. If you buy that… [Read More]

From the mailbag: After shooting with a d810 for an afternoon, I came away thinking that the sensor is blowing out i the highlights.

Nonlinear cropping
Well, it’s not cropping, exactly, but it’s related. Read on. Often with abstracts, there’s no way the viewer can see if an image has been distorted or not. That can provide some freedom for expression. Here’s an example. I started with this image: Let’s say I want it approximately square. I could just crop it:… [Read More]

Some of them, like this one caused by an insect crawling across one of the leaves: need special attention. However, there are many artifacts caused by motion of the leaves that could benefit from an… [Read More]

The conventional quick way to measure dark-field noise is to compute the ratio… [Read More]
