Needs Improvement mrcrow 2005-10-28 9:35

you may have gotten this the wrong way round
focus on the leaves...or a short way behind...and using a high f no say F16 it will sharpen the mountain...its the point of least confusion in a glass optical lens system for each and every aperture setting..
the picture is made up of rings..and this is the point where the rings ...of confusion are least...and gives depth of field..

for most lenses the best and most sharpest f is 5.6 or 8..but the dof may not be big enough..

a manual camera will have dof preview so you can see it or check on the barrel markings..

now how do i do that with my digi cam..??
use the mountains...landscape setting and pre focus on something about 3M away...and dont get any closer than say 1M from the branches..

:(...its not easy

Default To mrcrow: lesson ?

Hi Geof. Please, let me tell you that your critic is rather easy I think. I'm sorry...
1 - This photo wasn't made with a digicam but with a Canon AE-1, and this means I revealed it on the paper by myself.
2 - The focus isn't on the leaves but on the mountain.
3 - This critic would have been useful if you had made any comment about the contrast in the sky or on the leaves, or about the exposure time on the paper. The DOF is only a matter of choice, except in particular conditions, but the work in the laboratory is a real matter of patience and precision. In this, I'm not excellent, that's right.
See you. Eric...
