    I have always hated climbing under and out of a focusing cloth and messing my hair and having the wind blow the cloth in front of the lens when least expected and besides it's hot and you are vulnerable to what's going on around you so I finally made the perfect focusing hood, for me at least. Here are some pictures. The lining is a lightproof vinyl-neoprene and the scrim fabric is ballistic nylon and it can be found at Jo Ann fabrics for $5.00 yard and it can be sewn or glued with weatherstrip cement used fo car weatherstripping. Take a look.

    Very good idea, I'm very tempted to emulate that somewhat for myself.

    Thanks for the pictures.

    How do you hold a loupe in there? It seems enclosed on all four sides.

    Dear phaedrus;
    The hood frame is hinged in the middle for inserting a film holder and to use a loupe or if just using the loupe, the hood collapses. There's also a draw cord to shape the opening for individual head size and to allow the use of a loupe with one hand while focusing with the other. The hinged frame allows the hood to be used in both the vertical and horizontal without being awkward and still affords the same light shielding.

    If the back flared out the entire bag could cover the camera when the camera is folded. Maybe a flap inside that was velcro'ed that could be pull over the ground glass when covered to completely cover the back of the camera.

    this looks like an ingenious alternative to a dark cloth. But I am curious about what holds the hood in its open position. Is there some sort of framework inside?

    How do you breathe in there without fogging the GG? What holds the hood out away from the camera? I really like the look of it, appears promising, maybe not for 4x5 though.

    Interesting concept. You might try adding some sleeves so you can get your hands inside to use a loupe, but on the other hand, one can use a loupe with a folding hood and it doesn't have to be completely shaded as is desirable for seeing the whole frame.

    With a traditional darkcloth, it isn't necessary to climb under the cloth or to attach the cloth to the camera. I usually fold the cloth approximately in half, white side in, and drape it over my shoulders. When I want to use it, I flip it over my head and over the camera back, and I can quickly take it off, if I need to see what's going on around me.

    Dear Rick, Dan, Dave and Curt;
    Thanks for the comments and questions. The hood stays fairly erect without any framework because of the material and the use of the draw cord to form the opening. I can use a loupe over the entire GG by just collapsing the hood with my face or in a low light situation just open the hinge and I have access to the entire ground glass either way. I hold my breath while focusing and composing. If I have my whole face pressed into the hood and if I need to take a breath, I open the hood from the side where it is held closed with two Velcro tabs. Like most of us, I have fogged my GG when using a darkcloth too so the enclosed hood isn't that much more of a problem. I too, used a focusing cloth the way you describe, Dave, but I found many times, when standing on light colored surfaces, such as cement, sand, snow etc., I had to hold it tight against the bottom of the camera or have it held closed, or the light from underneath was just too distracting and I still ruined my coif. There now I have confessed! Vanity is the mother of invention! Curt, I didn't want to make the hood any larger than absolutely necessary and as I always keep the camera in it's own bag, it didn't need any extra protection. Thanks for the interest Guys.

    I'm the kind of do-it-yourself-er who would cobble something like this together (albeit not as neatly); except I've found the use of a black, short-sleeve golf shirt works fine for me. I put the shirt on around my neck, upside down (collar down, buttons toward the front) and then pull the bottom hem of the shirt around the frame of the camera for viewing. The arm sleeves are positioned in the correct location for fiddling with a loupe, etc.

    For air could you add a black mesh square of cloth to the bottom of the hood to allow it to breath a bit. I think it's an all around great design, the folding is particularly nice.

    Good work,
    Curt
