Re: [Cameramakers] bullet photog, mega-lens
I would much appreciate information on how I can contact this fellow regarding a lens making problem. May I have an email address, telephone number, or even his postal address? He might be just the person to amke up something for us! THANKS in advance. My email address for the information is <[EMAIL PROTECTED]> Bob Never give up is my second topic - I contacted a second buyer of one of those monochromatic 40 pound lenses - and he has lens software and can grind lenses up to 12" diameter. All I was armed with were ideas. He's had his apart already - it has 4 cemented pairs that are air-spaced. We're scheming about some sort of change. He claims it has no internal reflection, but I suspect one needs to look under the right conditions and not just eye-ball for reflections...no Bokeh?

You know Murray, It occurred to me that a muzzle flash is probably bright enough to trigger a slave.

[Cameramakers] bullet photog, mega-lens
Hello: Look up "Engineering and Scientific High-speed Photography" by William G Hyzer. Many techniques and theory. For example: .22 Cal. high-velocity bullet 2600 ft/sec, picture freq, 1.4 x 10^4 frames per sec., time magnification 860. Mind boggling book...most of the technology in there from 1950's is beyond hobbyist, but it's worth reading for the theory and ideas. I just looked it up on a book exchange and was surprised at the range of prices. Never give up is my second topic - I contacted a second buyer of one of those monochromatic 40 pound lenses - and he has lens software and can grind lenses up to 12" diameter. All I was armed with were ideas. He's had his apart already - it has 4 cemented pairs that are air-spaced. We're scheming about some sort of change. He claims it has no internal reflection, but I suspect one needs to look under the right conditions and not just eye-ball for reflections...no Bokeh?
