DOF and distance from the object
May 30, 2012 07:58:43 #
Honestly, how many of the experts see the DOF issue as a calculation rather than a result of what the photographer wanted to capture? Over the years that I have been using a camera I tend to work with the DOF based upon my study of what my gear is capable of producing and I check the result on the camera if is an important composition and reset if need be, for another attempt at getting what I want from the image.

The subject is really quite simple and straight forward, explaining it may not be. I found the best way to understand it is to play around with different setting and study the results, the clarity(!!!) will fall in place.
your images are good - just post em - no need to generate discussion.
Personally I've found the best way is simply to look - study - shift focus - look - study.

One thing to remember about DOF is that of the total dof one third is in front of the focal point and two thirds behind it. Remember that to make sure you background is or is not sharp. The actual total dof is dependent on the f stop and focal length. I don't know the math for that.

When explaining something that can be a very complicated, very confusing subject to a complete novice or someone that cannot understand a certain issue then to me it is far easier when the teacher or instructor can keep the answer short and easy to understand.
This is what I would have said and then expand on it. Yes a thousand times yes, we will get lots of folks coming out with excellent, technical and informative answers but when talking to someone that might not know a hippopotamus from a mouse, then keep it short, keep it simple.
Big numbers on the 'f' setting ie f22 equals a much bigger depth of field than smaller numbers ie f2.8 or f3.5.
Just my thoughts on this complex issue.
