IR stitches in CPA show

June 17, 2015 JimK 5 Comments

I’ve had a picture selected for the Center for Photographic Art Member’s Exhibition. I submitted ten images for the infrared freeform-stitched work that I did in a nearby oak grove a few month ago. My tentative title for the series is Los Robles. I’ll show you all ten images today, and you can play juror…. [Read More]

Focusing the D810

June 7, 2015 JimK 2 Comments

In the last few posts, I’ve been dealing with my problems in achieving precise, repeatable critical focus with the Nikon D810, which doesn’t have focus peaking. In an attempt to add focus peaking, I hooked an Atomos Shogun monitor/recorder to the HDMI output of the D810, and turned focus peaking on. Close, but no cigar…. [Read More]
