    : Try re-filming on either a 50% (or greater..) grey-card, or even black (?) Might help the camera cut down on the 'blow-out'.. Or, as I find I have to do when videoing demos for Clients is put a, like, 80-90% neutral-density filter over the aperture-window, and/or the vid-cam lens.. (depends on the vid-cam / settings, etc..) Experiment! ..but, that might help ya get closer-proximity to a 'wysiwyg' video-clip..

    ..In any-case, Thanks for the effort / sharing..

In particular, the 'Egyptian Pyramid' frames, and (...again, iirc..) the Saturn V-launch sequence.. Those 'tans' / sands, and Oranges in the Saturn-rocket flames really show-up the 'speed differences' between a Green DPSS, a 'VCSEL' Green, vs a DI.. And, as a result, color 'shading' differences.. (..Of course, also-depending on how each PJ is (manually..) color-balanced, and also the Pallete-tuning, etc, etc..)

    ..Also, the 'chick on the beach' frame / baby, etc - Any 'skin-tones', yes, are also super-subtle 'testers', but.. since those 'subjects' are 'whities' the subtle-differences are more 'washed-out'.. Seems like the more-difficult (for a slower-Green vs faster DI-red / green, etc) subtleties of the 'sand / earth'-colors in the Pyramid-frame, in particular, really show-up speed-differences, and color-shading ability, better..

    ..fwiw
    cheers..

    Hi Jon;

    Thanks for the suggestion. I agree a black background would help, but I didn't have time to set up a stand and a sheet or scrim. I might have enough free time to try more video on a black background next weekend, but I can't promise anything.

    Carlos:

    I did post a picture in this other thread showing the beam brightness comparison for the two greens (short version: not much difference), and there are lots more pictures showing the two different plutos (old and new) running side-by-side in my gallery.

    Several people have commented that the 532 nm green seems to "pop" a bit more, and I agree, but overall the brightness difference is very slight - perhaps 10-15 %. I think it has as much to do with the actual power differences (the 520 nm green laser is rated slightly lower than the original 532 nm DPSS unit) as it does with the wavelength sensitivity of the human eye.

    Adam
