Silly, really off-topic question, but in the pic that leads the article, does it look like he used a green filter? All the vegetation is really bright. I've only recently started using filters and don't yet have a handle on what will happen, except to know that one needs to be very careful with red, especially when one forgets he is shooting color film. That, and last night when packing my gear for a trip, a so-far-unused green filter did go into the travel bag.
