Monochrom Wednesday in IR. Day 11

Today I had lunch at our home office. In fears of missing a full day of taking pictures, I escaped quickly for 15 minutes to walk around the block. Unlike yesterday, when I struggled to get any light through a 760nm infrared filter, I used a 720nm on my Zeiss 50mm Planar. 720nm leaks a lot more visible photons that a sensor can harvest than a 760nm. This made possible to have ISO at 6400, f-stop at 2.8 and shutter to be between 1/125 and 1/250. I ended up with much cleaner pictures and a more enjoyable shooting experience.
