[Filter Test] Hoya U330 as a Dual Bandpass Filter

Just a snapshot made with the U330 with no additional IR-blocker. This makes it primarily an IR-pass filter when used digitally in the sunlight. The U330 gives things an unusual false colour twist.

Maybe I should have posted this in the Infrared Informal Section?? :lol:

D600-broadband + 105/4.5 UV-Nikkor + U330 + Sunlight

f/8 for 1/160" @ ISO-200

 

This version shows an in-camera white balance I typically use for UV work.

Where did that yellow come from??

Here is a more conventional white balance made on the big sail and a slightly different crop.

Raw Digger version - demosaiced and gamma-ed, no white balance added.

The Red Channel predominates with Green & Blue almost equal.

Added Feature: Shutter slop. And this just after I cleaned the sensor thoroughly.

Oh well. Time to convert a new camera I suppose.
