Originally posted by MattGunn Using basic (if slightly skewed) logic it should be possible to argue that by using all those photons to from images in our cameras we must be capturing them and so preventing them from contributing to global warming. Therefore the greatest contribution we can make to the prevention of glabal warming is to buy more big fast lenses - a 300mm f/2.8 must collect more photons than a kit lens.
I've argued for years that locales popular with snapshooters -- Golden Gate Bridge, Grand Canyon of the Colorado, Kremlin, Statue of Liberty, Yosemite Valley, Eiffel Tower, Mounts Fuji and Vesuvius and Shasta and Matterhorn, Disneyland, Melbourne Opera House, Brangelina -- are
Photon Depletion Zones. Massive photon depletion MUST have some serious environmental consequences, yes indeed. Who knows -- greenhouse effect, pole reversal, even orbital dynamics, may all be at stake! Large-scale studies of the effects, positive or negative, are urgently needed. Who, but this dedicated
Plethora of Pentaxians, is more willing to sacrifice their time and energy and expertise, to engage upon this arduous endeavour? Yes, for the good of all life on this planet and beyond, we DEDICATE ourselves to the intensive study of LBA, Photon Depletion, COD Economics, and Brangelina!
