| Suppose I'm taking a picture of a small item on a textured background--say a cockroach on the sidewalk (I use this example, because I would never get close enough to a cockroach on the sidewalk to take a macro picture of it!!!). Obviously, I primarily want the cockroach to be in focus. How can I get the background in focus also, both front and back? The focus of my camera is so tight, of course, in macro mode. Can I just set my aperture high (f6 or so) and my shutter speed longer? What would be a good length of time, and how can I keep it steady that long, given that my tripod doesn't shrink down to 6 inches. It only goes as low as 18 inches. Anyone who knows, please help out a brand new photographer. |

In macro mode, it's not very easy to get a large depth of field, even if you stop down all the way. I don't have an answer to the question, but, from experience, I don't think you can get sharp focus in a very deep field if your focal point is close to the lens... you may get a few inches to front and back and that would be about it...

It like being on a river edge and taking a picture off the tree and the waves on the river. If you focus the tree the river waves are out of focus and vis versa. The trick is to back away from the river edge and zoom in.

I think you will find that zooming in a macro mode will decrease your depth of field even more...

Increasing the focal length (zooming in) naturally decreases the depth of field. If you set your aperture at F5.6, your depth of field will be greater at a 50mm focal length than it will at 200mm. It won't necessarily make the subject out of focus, but it will help isolate the subject in a much thinner focal plane in the composition.
When I do macro work, I generally want a shallow depth of field, but not so shallow that my whole subject is not in focus. It's a preference thing though... it simply depends on what the photographer likes :)
