Image Sharpness Test
I did the following test to find out what sharpness I could get out of
my 35mm Camera.
The following photo was taken at Mt Ainslie, Canberra, on a misty day.
I used a Pentax "Program A" with a Pentax 50mm 1:1.7 lens, on a tripod.
Aperture was 8, can't remember exposure, something around 1/30 sec. The
film used was a Fuji Velvia ISO 50 slide film, known for it's sharpness
and fine grain.
After development, I scanned the picture directly from the slide at
2700dpi, on my Nikon Coolscan III. The scan has approximately 3600x2500
pixels, which equals a 9 Megapixel resolution.
This is the whole picture in low resolution, without image manipulation:
