Yesterday, I showed some color images of the hills that I made recently. Today, it’s equal time for the B&W infrared ones.
Winter hills in color
We’re getting to the point where the winter grass is beginning to grow high enough that it’s visible over last year’s dead grass. Time for a few color shots.
More on gamma and gamut
In this post, I opined that the gamut of an RGB color space did not depend on its gamma, or nonlinearity, subject to some constraints on the nature of the nonlinearity and the precision of the specification of the values. Thanks to a discussion with a DPR poster who I only know as JDin Oregon,… [Read More]
EFCS and Bokeh — a7RII with Otus 85/1.4
This is a rerun of yesterday’s bokeh vs shutter speed testing, with EFCS on and off, but with a different lens, the Zeiss Otus 85mm f/1.4. I set the lens wide open, and the ISO to 100. I lit the subject with a single Westcott 12×12 inch LED panel, with color temperature set to 5000K… [Read More]
EFCS and Bokeh — a7RII with Sony 90/2.8 macro
There was a recent post on DPR that showed dramatic effects on bokeh of EFCS. It was a apples/oranges comparison, with the mechanical and EFCS shutter speed different from each other, and the EFCS set to 1/8000, which is clearly out of the range where EFCS usually works well. Still, it got me thinking, and… [Read More]
