I think I already lightened it somewhat, but your version brings a bit more detail on the engine for sure. All my 1968 shots were made with a cheap Kodak instamatic camera. These had the little cartridge film containers you popped in. Viewfinders were terrible and really small. In 1969 I got my first 35mm, and in 1972 I bought my first SLR a Minolta 101. Am sure glad I got some color of the NG. My previous visits were B&W and with little box cameras. I was fortunate to have visited 4 times before steam was gone. First in 1956, then 1960, 1966, and 1968. I guess had I been older I would have had a better camera back then.
