    Im shooting this girl with a city line background. the city line is across the bay. So its a good distance from her

    In order to get them both in focus I would use an aperture as wide as I can get, but are there any other tricks to make her pop and keep everything in focus?

    thanks :)

    Actually you want a narrow aperture (larger f/#) not wider. Wider apertures result in less DOF.

    To make her 'pop' you could light the foreground so it exposes 1/2-1 stop above the background.

    so shoot at an f15 or something?

    I can use my SB-900 to light her up

    Hi, I'm fairly new to this as well, and loving it! :) I agree with the above poster - you want a nice, narrow aperture to get the best depth of field. I'd try several shots, and raise your f-stop in increments until you get the effect you're most happy with.

    What time of day will you be shooting? I'm not a huge fan of flash photography if I can avoid it (personal preference), and do you have a tripod? To help your subject pop from the background, maybe you could experiment with some lighting or reflectors?

    Best of luck! :)

    It is the other way around.

    Smaller the aperture, larger the F/ number will give you deeper DoF.

    Play around with this and see

    No the smaller the hole the more things are in focus. The bigger hole something like 2.8 lets a lot of light in really quickly and you get a shallow DOF. When you shoot at something like f/16 it's a pretty small hole and takes a bit longer for the same amount of light to get in and hit the sensor. This gives you a larger area that's in focus. You want a small circle. That is why when you shoot at something like f/1.4 or 1.2 there is such a shallow DOF it might look like the whole shot is out of focus. Hope that helps.

    No, the smaller the aperture (larger f number) the larger the depth of field. If you drop it down to 2.8 the background will be *more* out of focus. In many prime lenses with wide apertures (sometimes called quick lenses -- f/2.8, f/1.8, or lower) the depth of field can be so shallow that if you took a picture focused on one end of a can of pop the other end could be completely out of focus.

    Most people like to take portraits and model pictures around f/8. Gives a pretty wide depth of field and many people say it's the clearest f-stop for most lenses.

    Thats the perspective I want but more balanced lighting. Your background seems a bit blurred. but yes, she'll be that distance form the city line.

    So, you have a photography "business", and you have had no understanding of DoF all this time? Really?
