Geoff,
My last uploads where without the windows.
>>
Same beach,no windows but rain.
Distance is 1320 feet
I tried to upload a contact sheet with crops of the different apertures and
ISO,s but that gave an error message .
This is the full frame at F 8 and ISO 1600
http://gallery.leica-users.org/v/animal/canon/strandb.jpg.html
followed by 3 crops at 6.8/1600 3200 and 6400
2 at f8.0 1600/6400 and the last 2 at F16.0 3200/6400
Side by side it,s obvious that at that distance the image is best at F8.
Is there a way to upload a PS contact sheet?
Thx
<<
simon
