Hi All
Talking about vignetting. If I have a 67mm lens and I step it up to 82mm ND filter. Will there be vignetting? I guess it will occur if I step down; say from a 77mm lens to a 67mm ND filter.
Hi daredevil123
I have these parameters:
1. Focal Length: 12mm
2. Aperture: F/4
3. Circle of Confusion: (Using a D90)
4. Subject distance: 2m
5. Online Calculator gives a hyperfocal distance of 1.81m; near limit is 0.95m to infinity.
I think what I am trying to seek is how to I...
Thanks all for the advise. Wanting to do "aiming horizontal but very close to the ground". Any angle finder will do? I am using a D90 which does not have a swivel LCD. :(
Hi, I wonder how can I take photo at ground level up? I have backache and cannot bend down very low. Is there any accessories that I can use?
Thanks

Hi, would like to know when is the best time to use CPL? When a strong light source is above my head? Perpendicular to the camera? Beside cancelling out reflection, any other use?
Thanks

A qn. I have lens of different diameters and I have to get a filter for each diameter? Step-up/down ring recommended? For example to go from 67mm to 77mm, I have to get 2 rings - 67-72mm and 72-77mm. Will it cause vignetting?
BTW is 77mm a std diameter?
Thanks.
