    Lightbulb Light bulb burn out (No extra gear)

    If you wanna try this yourself.. Be careful!! The glass is really sharp and you’re dealing with power..

    I wanted to take those shot because I was fascinated by similar shots I saw on flickr..

    First you have to break the glass of the bulb.. It is recommended to break / manipulate the light bulb in a freeze bag or another plastic bag, because there are a lot of sharp little shards..

    One can use a drill to create a small hole on the top (or wherever you want) of the bulb.. The duration of the burn is depending on the size of the hole.. A small hole will result in a long burn..
    If you completely break the glass, the duration of the burn will be below one second, but the smoke formation will be more intense..
    One can see the difference on the images below:
    Light Bulb II - Final seconds

    Small hole
    Those were shot with a short exposure, large aperture and without flash.. The bulb was manipulated with a dril, the burn out duration is longer and therefore you get more shots.. The images were taken in a row (with 1/500s exposure and without additional light sources)..



    Light Bulb IV - Smoke

    Completely broken
    This is no fake or post processing trick.. The bulb and the smoke were really captured in a singles shot..
    On that one I used bulb mode (longer exposure as above), smaller aperture to compensate the longer exposure and a flash to freeze the smoke..
    The Flash was below the table, behind the smoke flashing towards the camera, manually triggered, 1/2 power

    On the second image I had to recolorized the smoke as I had a green “lens flare” on the bottom of the smoke.. But I tried to get as close to the original color as possible..

    Sorry for adding two pictures, but I think once can clearly see the different result from two different approaches on photographing a light bulb burn out..

    Camera Parameters for first series:
    Sony A100
    Sony 18-70mm @ 26mm
    ISO 100 - f5.6 - 1/500s

    For second:
    Sony A100
    Sony 18-70mm @ 30mm
    ISO 100 - f18 - 2s (bulb mode)


    All my howtos are available on my homepage pascalbovet.com

    Regards

    So, if I drill a hole in a light bulb it will explode?

    No no.. Its just the wolfram wire which burns.. But no worries, the bulb will not explode.. Its just smoke inside the bulb..
