Thread: taking potrait shots

    Default taking potrait shots

    I am still learning how to take better pcitures with my digital camera. Please suggest how I could take potrait shots of people's expressions and faces such that they are in focus while the background is blurred.

    I use a canon G1 . Thanks for any ideas.

    use a smaller fstop number to get less DOF. and focus on the face.

    pretty difficult to achieve with a compact from wat i heard....not really sure though...but on slrs the rule of thumb is to use a larger aperture...i.e f2.8

    but most importaint thing is control....totally blur also pointless..... and the smaller the aperture...the sharper.....

    even if u use the correct method as what ortega said, the G1 is stll unable to get significantly blur backround. for that u must use SLR

    Depth Of Field.
    Basically, the area that remains in clear focus when you shoot.
    I.e. using a small aperture reduces the depth of field and makes the background blur.

    Camera:-----blur-----|___in focus___|-----blur-----
    ______________________subject_________________
    Depth of field refers to the depth of the 'in focus' area

    For a much more detailed explanation:

    The definition used there is: "The area in front of and behind a focused subject in which the photographed image appears sharp".

    I think a slight error here.

    Using a small aperture INCREASES the depth of field, and vice versa.

    Example: for any given focal length, f32 (small aperture) will have a greater depth of field than f4 (bigger aperture).

    So if you want to have a blur background, use as big an aperture as possible.

    Ahhh smaller f-stop less depth of field man? Number 22 on the aperture is actually 1/22 or 1.4 is 1/1.4 which is bigger or smaller. Which have more DOF. Smaller F stop have more DOF OK?

    Took some potraits shots of my 4 months old niece today but it turn out to be under expose.

    I've tried to use the Arcsoft photostudio software that comes with my canon camera to enhance the photos but the results are not satisfactory...
    Any advice on any workflow technique that can be use to recover the shots?

    maybe some ps pro here can help u...
    but there's also a limit DI editing can do,
    if u really feel that your shots are really under-exposed,
    why not just take them again? =)

    since its ur niece, I'm sure u can always just drop by and take some more shots. hehe

    Hi socrates,

    Some others have already mentioned using a larger aperture (small f number). Larger apertures (opening in the lens) create shallower depth of field. This means a small distance in front and behind the subject (or person in your case) remains sharp.

    There are other ways as well.

    1) Coming closer to your subject also reduces DOF. Yes, that probably means you're capturing head-shoulder shots instead of half-body or full-body portraits.

    2) Adding a teleconverter lens in front of your G1 to increase the focal length should also reduce the DOF. (I think G1 has that accessory -- I use G2.)

    If I'm correct, the G1 has quite a large aperture (around f/2.8?) at the telephoto end of its zoom lens? Although most lenses don't perform well at large apertures, images shot near the largest aperture on G1 and G2 are quite sharp! Give it a go!

    Oh yes, with digital cameras, DOF is generally more than film. So, if you shoot film on the same focal length and aperture, you get stronger blurs in the background than with digital.

    As for the facial expressions, it's going to be hard putting it all down in words. I think I'll leave it out. Sorry.

    If you want to get DOF the PS way, read this article by megaweb - http://megaweb.clubsnap.org/articles...6_bg_blur.html
