    Hi, I need some help with photographing products.

    I'm trying to photograph prosucts and have each image be completely in focus, with no depth of field at all. I've tried a number of different settings, but I can't seem to take a completely uniform picture of any object that has depth. What can I do?

    I am using a Nikon D70.

    Use aperture priority or manual mode and set the aperture as small as possible.

    I'm still getting some blurry areas of the subject. It's like the center is in focus, but the edges are blurry. Aperture is at f/4.5. I can't show any examples right now.

    4.5 is a comparatively large aperture. You need a smaller one (higher number).
    Also, your terminology is confused. If you want all of a subject from front to back in focus, that's a larger depth of field.

    Small aperture = large f number. Try f/16, f/22 or whatever your lens can handle on the far end.

    And as chrfr noted, your use of the terms is reversed. When people say "no depth of field at all" it usually implies a very small (shallow) depth of field, that is, only a sliver of the subject is in focus, the rest is blurred. What you seem to want is the exact opposite.

    Aha! Thanks everyone. My terminology was reversed. A little confusing is all. The smaller f/stop is a wider aperture. Pictures are clear now.

    4.5???? No it goes the other way. Try f/16 or if you can if the lens goes that far f/22
