Re: [APML] first test with anti-newton glass



Hi !

Brian , sure it was late , not longer after the dawn apeared :)

Roland , I used 3 differents lens : 16mm @ f 4 , 28mm @ f 2.8 and a 50mm @ f 2.8 , maybe the vignetting is due to the light polution or maybe I should use these lens at f 4 or more to prevent the vignetting ?!? I'll try again my test with a longer exposure with the AN glass and maybe close a litle bit more the diaphragm.

Thanks for your comments  !

What lenses and f-stops? I like the AN effect, but all of the images
appear to have some significant vignetting and I'm wondering if it's
the lenses or there is something funky happening with the glass.
