A shot of a little caterpillar...

[Contegni]

I was walking in a park today doing a science project for school and saw this little guy just hanging out on a plant. I kind of completely blew the composition and probably could have gotten more of the caterpillar in focus but oh well..

Macro is tricky, especially if you are w/o a true macro lens.Looks like you got focus right, but just need more.

When you're shooting up close to the subject the DOF becomes very, very shallow if you're using a macro lens and a large aperture opening (lower f/stop numbers). To get more of the subject in focus you have to use a smaller aperture opening (higher f/stop numbers), have really good lighting (flash, reflectors, etc...) and try to get the subject all on one plane if possible.

One technique you could try is focus stacking, but this only works if the subject isn't moving much.
