With some photos, I used photoshop and did some editing.
I borrowed a school camera for the weekend, but at lunch, I went to Mr. Ku's Physics tutorial to try and get some photos. This was the only decent photo that I created.
ISO: 100
Aperture: f/4.8
Shutter Speed: 1/20
Colour selection tool used on the camera
Photoshop edits:
Selective colour edits -->
Red colour layer:
Cyan =30%
Magenta =68%
Yellow =53%
Black = 26%
White colour layer:
Cyan =100%
Magenta =6%
Yellow = -100%
Black = -100%
The last image is very impressive. You could try using a black and white filter but leaving the red tube visible.
