Hi

I couldn't manage to get all of this in focus, I must be doing something wrong.
I was using my Sigma 70 - 300 set on Macro at 300mm, and F11. Tripod and 1/40 sec exposure. ISO 200 on an EOS 400D

I am now thinking that at F11 at 300mm I had too small amount in Focus due to Depth of Field.

Would I have been better off using my Sigma 24 - 70, which does MACRO, and just getting a lot closer, or should I have reduced the aperture and gone with a longer exposure, or even upped the ISO.

Many Thanks for any advice given.

Steve

f8 @ 50mm and iso 200 to get 1/80 at least i think on the overcast day.

The overall prob is the shutter speed here.

And at 300mm how on earth did you expect to nail the stamens.

It is difficult to see what you were focused on. In any dgree of macro work the DOF Becomes almost paper thin. Have another try with the subject, select the smallest of appartures that the light conditions will allow. Have the camera mounted on some support. Never hand held. and focus on the pattern of viens in the petals.

Hmmm, I think I need to use a different lens then and get a bit closer, and pay particular attention to exactly what I am focussing on. So am I right in thinking if I was to use 50mm I would have much more Depth in focus than I would have at 300mm using the same aperture setting.

Many Thanks for your help so far.

I don't think it is as much the lens you use as the apparture you choose. to get maximum DOF select the smallest that the light will allow.

I felt sorry for this poor little flower, so did a couple of mods. In the first one, I adjusted highlights and shadows and just used "clarify" to get some detail into the petals, then sharpened. In the second one, I used "depth of field" and selected just the centre to be in focus. Enjoy!

Wow, many thanks, I obviously need to start learning more about the tools available in Photoshop, these mods make it look so much better.
Also going to make a determined effort to take a better pic in the first place. Many Thanks for your time and help.
