Josh... Is there any particular reason you are shooting with manual focus and not auto focus? Is this what you usually do? I use the Nikkor AF-S 18-55 quite a bit and find the auto focus very accurate.

Oksana, thanks for the explanation. In my opinion, the ISO of 800 used here gave the photo some degree of noise. But all the same nice shallow depth of field even with the kit lens.

No, Daniela. There is nothing wrong with faster shatter speed, if you want to use f/4. In situation with Josh's image he sacrificed his ISO agains faster shatter speed. His settings were: F5.6 1/800 sec ISO800, which give him "OK" exposure. You always want to keep your ISO as low as possible. In this situation it is possible, because he can slow down his shatter speed. Such a fast shatter speed as 1/800 is not necessary. It doesn't do any damage, it is just not necessary. He could use shatter speed of 1/125 instead (where is 2 2/3 stops of the difference between 1/800 and 1/125), when lower ISO to 125 ( where is 2 2/3 stops of the difference between ISO 800 and ISO125). So he should shot this at F5.6 1/125 ISO 125 instead.

There is nothing wrong with using f/4 or f/5.6 if you want to get shallow DoF. Also most of the lenses are the sharpest at the aperture 2 stops closed down from the widest possible aperture. Let say your lenses widest aperture is F2.8. Your lens would be the sharpest at the aperture f/4. If the widest aperture is F8, your lens would be the sharpest at the aperture f/8. And so on.

Yes that's it! I have huge problems with my pictures because I'm always trying to work with the better apperture on the lens, and sometimes in order to keep a f/4 or so, I bring the shutter to a very fast speed. I fixed in my mind the strange idea that the apperture must be f/4 or f/5.6 but it's a wrong idea isn't it?
Oh and other thing... I saw this photo from Josh this afternoon in the screen of my office and the photo seems to be darker that now I'm seeing it in my nice screen from home. This could be a problem in what concerns working in post prodution because we are going to print some photos and sometimes could be make some lightroom corrections that will not match in printing and even in other screens. Well I heard about a monitor screen automatic calibration like Spyder 4 PRO but it costs 148 euros (it's a lot of bucks to use just a couple of times). Isn't any other cheaper way to calibrate different monitors (screens) to show the same? I think Josh portrait almost convince me to buy a calibrator to put all my monitors equal and we real colors.

Daniela, If Josh would slow down his shatter speed, he could use a lower ISO. The shatter speed 1/125 could be enough, since subject is not moving.

Nothing wrong with that lens for you to say "still using...". It's a nice lens.
I believe you use the ISO 800 because subject is under shadow and the meter indicates the need for for light. Maybe in ISO 200 you should be ok and if the girl was a couple of meters away maybe the sun with natural light do the job.

Not bad for the first time. I like the composition and dof. Which lens did you use? My suggestion would be to use lower ISO and slower shatter speed. You don't really need a shatter speed of 1/800 for subject which a barely moving.
