Hi, how to have shallow depth of field for portrait photo during day / night time. What are the settings. I know must have big aperture but i can't get it right. Only when taking small objects at near distance then can. Any tips? Btw, I'm using D40.

use max zoom, let's say 70-200 ( u choose 200)
then biggest aperture, meaning f3.5-f5.6, you choose f3.5

No.. if he's at 200mm then he can only choose f5.6. ;p

is there even a 70-200 f3.5-5.6?

and if he chooses 200mm, max aperture is 5.6
not referring to the same lens ;) just asking him to choose the max focal length + use wide open to achieve as much bokeh as possible.

sorry if it was confusing

If's it's a variable aperture lens. The smaller aperture will be for the max zoom setting.

For e.g. Nikon's 70-210 f4 - f5.6

at 70mm f4 is MAX
at 210mm f5.6 is MAX. You can't get it to open to f4 at 210mm...

hihi, guess it wasn't a good example. ;)
my mistake.

probably more applicable with constant aperture rather than variable aperture.

Hi cichild,

correct, getting closer to the subject also helps.

Using the widest aperture on your lens helps too.

Happy snapping.
