Hi,
am jus puzzled that if i try to take a landscape picture, what is the difference between using hyperfocus method and focus infinity method ?
:dunno:
its only good if you have a manual lens with you
LFC25 said:I tried out the hyperfocal distance method but doesn't seem working out for me. Here's what I did:
After determined the distance (say 1.45m), I walked up to a subject (ard 1.5m) and half-pressed the shutter to lock the focus. Then I bring up my camera, re-composed the frame and depressed the shutter.
Only the foreground is in focus.
Is my method wrong?
Can you post a picture with exif information?
At 1/60 under the condition I think the fence is over-exposed.
Since you are not including anything in front of the tree trunk, why set your target on the tree?

I was trying to use the hyperfocal distance method.
My kit lens doesn't have a distance scale therefore I est. my foucs at the tree which is roughly the hyperfocal distance.
Here it is: 18mm, F-11 1/60
I focused at the lower part of the tree (abt 1.5m from my posistion). Then brought up my camera & re-composed.
The white fence behind is out-of-focus. Not sure if u can see from the small thumbnail. Just wondering is it due to re-frame that caused hyperfocal distance don't work?

Because your calculation seems to be incorrect. Check the links given, calculate the DOF manually for your settings. You want to have the tree (1.5m from you) and the fence and all behind (~ 50m to Infinity) in focus.Here it is: 18mm, F-11 1/60

It's not about the distance scale, there is always a way to estimate. The question is rather: where is your Near Limit? Which object close to your cam still needs to be sharp? But as you can see from my results: there is no need to focus on this point, focusing further into the distance still gives sufficient sharpness. Maybe you redo your Maths and compare with the links provided?*Octatine, for 18mm F/11 the DOF Master calculated my focus distance is 1.45m, hence I focused my camera at the tree which is abt 1.5m ( you're right it is a rough est as my kit lens does not have a distance scale).
