Haven't been here for a while - have sold my last Nikon Body, though I still have some glass and an adaptor for the A7R...

Here is one from New Zealand from the Eglinton valley on my way back to Te Anau from Milford Sound....

Saw this guy a couple of years ago in Montreal. Must have been 20 degrees and he's blowing bubbles like it's August.

This is an image of only the heat of the sun, i.e., from about 700-900nm. The filter appears black to the naked eye, and the sun shows up only in live view, where it must be manually focused. In spite of the fact this is the sun, the filter makes the exposure requirement of ISO 3200, f/8, at 1/25th sec.

More accurately, the transmission is about 1 % at 800nm, up to 88% at 900nm.

Sun with IR Filter 800+ nm transmission 05.22.15

The B+W 093 Infrared Filter blocks the entire visible spectrum and looks completely opaque. Transmission only begins to exceed 1% at 800 nm, rising to 88% at 900 nm. The filter factor is in the range of 20 to 40.
