Macro focus

Hi - I have been trying Macro shots but seem to only get the tiniest bit of the bug (or whatever) in focus. When I look at the wonderful macro shots in here most of the frame seems to be in focus. Is there some trick that I am missing or are the images shown here cropped out of larger images to get the portion that is in sharp focus? Or is it as simple as me needing a different aperture to get the depth of field needed? Any tips from the experts greatly appreciated!!

Re: Macro focus

Well if you want DOF you are into using small apertures but the best tip I can give is to take a quick look up from the eyepiece and check that your subject is as paralell to the camera as you can get it. If you are using a compact then the DOF shouldn´t be too bad because of the short focal length of the lens.
However Great DOF isn´t everything and very selective focus can be effective in some instances.

Re: Macro focus

if the depth of field is problem in your macro shoot you can stack them using multiple shoot in photoshop, there is also a softwar call helicon focus for this purpose.

you need a hardware, it is call macro slider attached to your camera. so you can fine tune your macro fokus distance.

Regards..

Re: Macro focus

As suggested above, there are three ways to maximise focus:
1. Smaller aperture
2. Focus stacking - multiple shots of the subject at different focus points and then blending using software or manually
3. Technique. Ensure at right angles to subject

Personally, I tend to compose the shot to allow for the DOF, so not restricting myself. i.e. if there's not much light, I'll focus on the critical components of the subject (usually the eyes) and allow the DOF to fall away, making the composition suit the shot

Re: Macro focus

What's been said before.

I normally don't crop. Also if looking at some shots that are in the macro forum, some are not 1:1, but further back maybe 1:2 so the DOF at the same aperture can be bigger. The higher you magnification the smaller the depth of focus field you get at the same aperture.

Also look at the angle you aproach the subject - getting a plane of view that is roughly parallel can get more of the subject in focus at a small aperture. Angling slightly can create an illusion of focus if you get the key part of the subject in foucs - eg eye of bug.

Re: Macro focus

....also remember it's not a 100% success rate if you are photographing in the field. Calm days will give you the best chance so practise, practise, practise
