Jim,
I knew you had shot it on a D300. The sizes in these DSLR actually vary a bit in size from camera maker to camera maker so I refer to them all as half frame 35mm. To be accurate the D300 has an APS-C size sensor which is 23.6 x 15.8 mm = 372.88 mm". 35mm is 24 x 36 mm = 864 mm"

as for being shot on a "35 half frame camera", not so...this was taken with a Nikon D300, a DX format DSLR...DX format for those who don't know is 2/3 of a 35mm frame...the ISO 3200 is correct, that's what Auto ISO came up with in the relatively dark portion of the woods behind my house...
no worries Roy, I'm just terrible at
math...the "half-frame" designation just seemed off to
me...I was going by this from Wikipedia-
The 1/3 smaller diagonal size of the DX format amounts to a 1/3 narrower angle of view than would be achieved with the 135 film format (35 mm film or FX format), using a lens of the same focal length
so my assumption was if DX is 1/3 smaller.
it's 2/3rds the size of 35mm, not 1/2...the math on the area size does
tell a different story...it's always a good day when I can learn
something...
Jim
