    Hold on. There is some misunderstanding going on between what you are doing and what we are saying.
    Are you saying, you have made a cut out of some card and stuck on the lens like a filter? This way you'll never get what you want.

    yes exactly! :confused:

    This is what I'm referring to:
    Create your own bokeh
    and
    Aperture Mask Project!

    @zack This is a lighting done in a nearby traffic island during the festivals of Diwali, I was focussing on a small statue in front.

    In general the more distance between light (You want bokeh from) and the foreground subject you will get better results.

    The cut out project I understood, but like Henry said it wont create beautiful results you want.

    Perhaps your lens thread is small for such project (I assume its 52 mm) or you can try it on a kind of tubing in front of lens and then cut out at its distal end.

    Okay I tried it again tonight!

    To clarify, this is my cut-out .. its black on the other side, that is, the side that doesn't faces the lens!

    The cut-out / Aperture Mask

    One mistake I sure know I was doing was concentrating on 1-2 lights.. Today I tried with about 5-6 sources of light around me so that the number of circles in the bokeh is more!

    This was the bokeh without the mask!

    There were the best results I could get:

    16-DSC_0953.JPG

    14-DSC_0951.JPG


    EXIF for both is:
    1/10s, f/5.6!

    I think both reasons as stated by you, Henry and Narender are bang on correct, that is, lack of wider aperture and a better source of light!

    Also, I think I'll be needing a bigger, and a sharper cut-out! :rolleyes:

    Will give it a shot again tomorrow with better preparations! ;)

    With a larger aperture mask, I'll have enough space to focus on a subject and create the bokeh in the background, thus getting a meaningful shot!

    That is what I'm leading to with this!

    If you are doing this experiment with 18-55 lens,you may not produce nice bokeh.
    Dont try that heart shape cut out unless you learn the art of bokeh.
    I guess,while creating bokeh,you are blurring the light source.They are not OOF.
    Try placing a light source(like Diwali lights) in the background
    place a well illuminated object in the foreground and focus it,background light may produce a cluster of bokeh
    My humble attempt with 50 mm prime.In this shot,the gap between lamp and lights is around 10 feet.More the gap,nicer the bokeh.

    Agreed! :)

    Hmmm.. I understand the shortcomings of 18-55.
    The idea behind a prime producing a better bokeh is lower aperture right?

    About the distance, I do understand the farther the better.. But lets say I want a bokeh that is filled with over a 100 circles in one frame. What kind of light source can possibly produce that?

    A very enticing Diwali Greeting Masterji! :)

    damn right it is! :eek: Superb bokeh!

    Every circle in the picture represents a bulb?

    I guess not. One bulb can create more than one circle right?

    Negative.
    One bulb,one circle.
