Chadt CAM watch M1 (8x11)

Discussion in 'Minox' started by eric__, Jan 11, 2000.

  1. I have wrist watch camera that have no lens inside. Used 400 asa 8x11 film. I shoot the documents that laying on the desk and ceilig is white floursent light. The pictures are fuzzy and color as yellowish. Should I try for black and white color only or how far should i shoot into documents from top? This is purpose of spy camera. There is no flashing on the wrist watch camera.... Please help and advice.
  2. <p> I don't believe your watchcamera has no lens. Its lens is recessed.
    <p> You need to set the aperture of your watch camera to between f5.6 to f11. F5.6 being the aperture on Minox EC.
    <p> At f5.6 you can get object between 3 feet to infinity in focus.
    <p> If you want to copy document, then you need to stop down more.
    <p> If your camera has only a fix aperture (ie, there is no aperture control dial at the back of the watch camera )
    then don't expect it can copy document.
    <p> In general, watch camera is used for taking candid picture of people, not copy document, as these type of camera
    has not focusing lens.
  3. The yellow colour comes from using daylight film in artificial light.
    You should use special film for indoor purpose, a blue filter or a

  7. Chadt cam watch M1 is a smallest 8x11 camera, at front printed :"cam watch M1), at the back "Chadt" "Made in Germany".It is sort of a Brownie of 8x11 format.
    A lever serves the function for film advance and film tensioning
    (move the lever 4-5 times ). It appears to have three shutter
    speeds, corresponding to sunny, hazy and overcast; I thought those
    positions were for three aperture setting, however it seems that
    the shutter speed changed.
    Inside the camera, there is a three claw spindle, which turns
    when the film advance lever is activated 4 times, during which
    a small spring is seen stretch, that cocks the shutter.
    I am not sure this M1 has any Minox EC style film gate, which
    should open up when the film advances, and close up when shutter
    release pressed-- the film gap does not seem to change.

    There is a pull up frame serving as a 'viewfinder', which
    is not to 8x11 proportion.
