Canon Powershot A495

Canon Powershot S95


Galen and I visited this steep slab of Cheshire quartzite with three cameras: a normal Powershot S95, A Powershot A495 with the IR block filter replaced with a Wratten 87 filter, and a Powershot A810 with the IR block filter replaced with an infrablue filter (Rosco #2007). Photos from each camera were stitched into panoramas in MS ICE. The upper RGB image depicts the slab more realistically - it is flat and falls steeply from the top of the cliff. Most of the nearby parts of the Champlain Valley in the view are in Salisbury, VT.

Photoshop was used to isolate the red channel of the stitched near IR image to produce the grayscale NIR image.

After the infrablue photos were stitched together and output from ICE as one jpeg, that was opened in Fiji (ImageJ) and processed into NDVI. It was also opened in Photoshop and processed into false color IR (NBG) by swapping the blue and green channels.
