Went out to play with my full spectrum camera again.

This was in normal true color, taken with the normal boring Sony camera:


This was in "full spectrum" with the altered Canon camera:


For those who are new to this, camera pixels are quite sensitive to Infrared and a bit sensitive to ultraviolet. They usually have a filter in front of the sensor that removes any non-visible light. The pixels are also somewhat equally sensitive in the IR part of the electromagnetic spectrum, so they all get more signal from that IR, and green foliage reflects all IR quite well, that's why all the greenery in the photo above looks washed out... and why it becomes white when the visible part of the spectrum is blocked out... see below.
Also, more spectrum, wider rainbow, right?

On this one below, I cheated and swapped the red and blue channels to get that nice blue sky... and water.


Unswapped IR image with a filter removing anything below ~600nm (my variable filter can span between 550 and 750nm, but doesn't have numbers in between, so I guess this was taken at around 600nm, maybe it was 650nm, I don't know):


Same as above, but channel swapped:


Channel swapped, but this photo was taken with a filter at 720nm (that means we get less visible and more IR light):


Channel swapping is fun. This one also using the 720nm filter, known as R72:


Back to my variable IR filter set to ~600nm, also channel swapped:


More channel swapping at ~700nm:


Back to "standard" IR filtered at ~600nm:
