    Hiya,
    i just got my new canon 100mm macro lense and a 25mm Extension tube.
    ive not yet got my ring flash thats coming in a couple of weeks. ive taken a few pics with it and would really appreciate some tips on increasing DOF as i appear to only have a very small area to work with. i understand the focus area isnt going to be massive but i was hoping it would be more than i have managed in the pictures below.

    Macro can be an art all it's own. I find a tripod a must along with very small apertures, f/22 or smaller. Also, subjects that can be positioned as close to parallel to the sensor/film plane as possible helps with DOF a great deal. Great macro shots can be a real challenge, but the final result is worth it.

    As jstuedle hinted at, for a larger depth of field your F-stop needs to be higher. What was it set at for these photos?

    Yes, your need to stop down. The first was taken at f/4, the rest at f/2.8 according to the EXIF data. You should stop down to at least f/11 - try different apertures to learn the relationship between aperture, depth of field and sharpness.

    Best,
    Helen
