    combating glass fogging in the cold

    Hi

    for reasons which escape me I like to use my 4x5 camera outside when its cold, I seem to find my best subject matter that way.

    Among the challenges this brings is the problem of focusing without fogging up the screen. This is my (home made) dark cloth. Its light weight, dark, water proof and the silver side really helps keep it tolerable in the heat (when I'm home in Australia). Here in Finland I have other problems ...



    When its less than -10°C I have trouble with the glass fogging up (and then freezing fogged). Presently I hold my breath, but I'm thinking of using a snorkel to see if this works ... anyone have any tips?

    Waxing the glass will prevent fogging.

    Why are there no speaker jacks on a stereo camera?

    Make a focus shade for the back & don't use a dark cloth then you aren't trapping the warm breathe around the screen, hold your breathe too

    been thinking of something like that ... just have to figure out how to hold the loupe when focusing ;-)

    thanks for the suggestion!

    days like this



    when there is a stiff wind and its below -20 makes holding the metal of the camera (its a kind of alloy rail camera) very challenging ... even with thin microfleece gloves

    Letting the camera get cold will lessen the fogging. Usually you get fogging when glass is warmer than the ambient environment.

    A scarf around your face will not only keep you warm, but keep your breath off the glass as well.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    You should be able to work without a loupe for shots like that, although it depends what screen you have. My Wista is very easy to focus without and so's my Crown Graphic since I added a fresnel even in quite low light levels.

    The Speed/Crown Graphic's, MPP's, Linhosf's etc all come with a focus hood which is detachable, but you could make or buy (Custom Bellows, UK) a bellows style screen shield, or make something from black card . There may be one made for your camera. There are also the binocular type focus devices for some cameras.

    Mike Nesbitt used to make a wooden field camera with wooden knobs etc for cold weather use.

    Another option to prevent the screen misting up is a silicone liquid, a friend used to use something to prevent his spectacles steaming up ask in an opticians/spectacle shop.
