#1, not enough DOF.

Let me see if I understand this.
If the f-stop number is too low,
that will make the picture too soft,
and appear blury? Or, are you saying
the f-stop number was set too high?

Thanks!

Oh, and I like the light bulb pic. :thumbup:

No, that's not what he is saying at all.

DOF is that portion, from foreground to background, that will be in focus.

Depth-of-field (DOF) is in part controlled by the lens aperture. At large lens openings like f/2.8, the DOF can be very shallow. At true macro subject distances, the DOF is usually a small fraction of an inch and if the subject is larger than the DOF parts of it will not be in focus.

Subject to lens distance is one of the other factors that control DOF.

Skilled macro photographers us a technique known as 'focus stacking' to substantially expand the DOF in the final image.

Thanks for the explanation. A quick google search
reveals that focus stacking uses multiple images,
along with some software, to achieve a near perfect
macro picture in focus.

:thumbup: Can also be done handheld if you practice and pay attention to what you are doing. I hand focus stack my 1:1 macros all the time and it can really help an otherwise worthless image due to poor DOF at such high magnification.
