Wow, what fast response, this is a kick-ass forum.
I should elaborate a bit on my dilemma:
1. the problem im having with full figure shooting is that I focus in on the subjects face (using program mode) and everthing else is out of focus ie: clothes. shoes, etc.
2. when shooting in aperture priority, im 2 stops from the smallest aperture on the tamron, which allows a fast shutter speed, however the focus is still attained to whatever is in the center of the reticle. How can i tell the camera to focus on the entire figure?
These statements seem to be a little confusing. At least to me they are..
When you say Smallest Aperture, what exactly is the F number (aperture) you are shooting? If you were 2 stops from the smallest aperture, that really means that your using F/11 or F/16
And if you were using such a small aperture, most things would be indeed in focus- which is contradictory to what you stated. Or were you meaning clicks instead of stops ?
Statement #1 seems to indicate that you are using a LARGER aperture, i.e. the number reported in the aperture is actually a smaller number, such as 4 or 5.6..
Semantics aside, you're going to want to use smaller aperture such as F/8 to F/11 perhaps to get more in focus, and a moderate to telephoto focal length- like in the range of 50 to 200mm to get separation.. You probably will also want to separate the subject a distance away from the background as well.. And yes, you will want a flash or a strobe. It will make your lens sing.
I would suggest that you go to http://www.dofmaster.com/dofjs.html
and put in the numbers like your to-subject distance, selected focal length, and aperture settings- to see the amount that is in relative focus. You probably don't want to go with a smaller aperture than say F/16 though- it might cause other issues not apparent on the viewfinder.
I guess I neglected the obvious statements, or not so obvious statements...
A smaller aperture is actually a larger number like F/11 to F/32, whereas a larger aperture is actually a smaller number like 3.5 to 5.6.. A smaller aperture ends up with more stuff in relative focus, but a slower shutter speed, and a larger aperture gets less stuff in relative focus, but ends up with a higher shutter speed. This assumes that you are using ambient light- and not using a strobe/flash. With the flash or strobe, you are allowing your camera to effectively take the shutter speed out of the equation if so desired - providing the extra light required by the smaller apertures.
