Hello friends,
here is a picture of a flower in the back-yard of my house. I took it last sunday

Very nice but as usual I'd like more DOF.

Yeh, I agree, maybe a little tighter croping at the bottom aswell, not sure.

Hmm, i just noticed the tip of the plant (dont know any techinical terms- stamen?) is out of focus so a smaller apeture would of sent it even more out of focus. I would say use a DOF long enough to keep the whole flower crisp in focus and then maybe diffuse or blure the background in photoshop afterwards.

Smaller aperture = larger depth of field so more of the pic will be in focus.
Only downside is you need a slower shutter speed.

wider aperture = brighter picture = smaller number = shorter d.o.f.

so, i think it would be nice to have a longer d.o.f. in this photo as well, because the middle is out of focus. apart from that, i like the photo, great color

Thanx friends for all your comments...

is there any thumb-rule for selecting apperture for a particular DOF?

to be more specific say I want x unit length of my pic to be in focus, so what should be my apperture setting? is there any mathematical formula or any rule like "sunny 16" rule for exposure.....

A lot of cameras have a "DOF preview" button which helps somewhat but since it normally darkens the scene considerably it's just a rough guide.
This unfortunately means that a lot of it is a trial and error method so in this case I'd start with the good 'ol F8 and work from there, you'll get a feel for it in time.
Good luck and keep on clickin'!
