Some pictures of the weir in Muehlacker, IR and normal, different exposure times

 

 

IR composite picture, original IR + normal pic

IR composite picture; I've used the original IR image and a normal one, just another transparency of the normal!

... also IR composite but another "normal" image and red / blue channel swapping in the IR pic...

 

... and here some of the "source pictures":

This is the infrared view on the weir with approx. 25 sec. exposure

VVery short exposure time...

... compared to a quite long exposure time (longer wasn't possible, I only have a 4x gray filter ...)
