The
D70 appears to be sensitive to some infra red and the above images were shot using
a Hoya R72 filter. Take a special white balance of the sun on green before exposure.
The left hand one was processed in Photoshop using auto levels first and then
channel mixer and hue and saturation. However the 87 gelatin filter gives me a
very blue result after exposure but its black and white version is OK. See the
images below all shot on a tripod for a change. I shall have to test the 87 further.
