    Default Blur Picture

    Hey guys,

    Can I check with u all!!

    How do I get pictures with the back picture focus while the front is blur??

    I know how to get the background blur but what abt the front part blur instead of the background??

    Do I need a special lens?

    if i am not wrong, you can just focus on the background and your foreground should blur. The distance of the 2 object will play a part as well.

    *Pros - please help to clarify if i give wrong information hor.*

    PS: i just try to share what i have experience and my knowledge may be wrong hence please dont scold me hor.

    Apart from focusing the subject wide open (low f-numbers) to minimize dof, you can also try having the foreground less than the minimum focus distance (mfd), that will guarantee it will be blur. Whether feasible or not will depend on the scene you wanna take.

    You do it the same way you did to get the background blur and foreground sharp. Actually I find it pretty easy to use manual focus to achieve this effect.

    If die die must use AF, then manually select your focus point, then lower your aperture value (bigger aperture) and focus to the subject at the back or "background"... This should give you a good foreground blur and background sharpness. However you must also take into consideration of the distance between yourself and your subject in question.

    No need, just need shallow DOF, that can be achieved with a number of ways.

    No need special lens, just need one thing: Your camera manual and a little common sense. If you want the background sharp and the subject blurred, it's the same as getting the subject sharp but blurring the background... Except you focus on the background. Easy and logical, right?

    Use a larger aperture 5.6 or so this will help you get a shallow depth of field then focus on your distant subject try using the spot focus on your cam instead of evaluative and you'll achieve your results.

    No such thing as 'evaluative' with regards to focusing. There is "Evaluative Metering".

    Hmm 5.6 isn't exactly wide, for a lot of cases, it would not be enough to blur the foreground/background

    no, you just need to read up more on depth of field.

    In order for the foreground to be blur, make sure the foreground is outside the object depth of field.

    yes, you are right.

    The best and easy way to get a shallower DOF is to use a biggest aperture you can afford.

    DOF is affected by a few things:

    Size of the Sensor (which you can't change unless you buy a different camera)
    Aperture (the larger the better)
    Focal Length (The longer it is, the shallower the DOF)
    Subject Distance (the closer your subject is, and the further the background, the shallower your DOF will appear to be)
