Frame averaging
Otto Flechtenmacher was a painter who lived in Austria, an uncle of Christa. I often did photography for documentary purposes, especially paintings.
This morning I listened to a workshop of portrait photography. To some extend the audience received explanations of the PhaseOne camera, which I use quite frequently. The vast dynamic range and the frame averaging feature of a PhaseOne were mentioned.
To reproduce these features I intentionally underexposed a photo of a painting of Otto. The original histogram can be seen on the left, the processed one on the right. The quality is quite surprising, when you are used to full frame sensors.
To compare the quality of a single shot image to frame average files, I did a sample of a single shot and two shots of 5 and 9 averages. Clearly, noise will be reduced. At the same time, structures come out more detailed, what might be seen from the following examples:
I never thought of using this feature for landscape photography – but it makes sense. By applying frame averaging you can get a landscape photograph with preserved highlights and well structured dark parts.

I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.
