... As I may have said, ISO was the same in both
instances - 200. No automatic ISO. EXIF data shows ISO and
Exposure to be
the same.
Shel,
I just took a look at the two pictures you posted.
EXIF shows ISO and *shutter speed* to be the same. It does not show
aperture. As I said in my previous email, one was made at wide open
aperture (f/3.5), the other at f/5.6, because of the type of lens.
EXIF data in these two exposures below, edited for items related to
exposure for brevity:
