I was hoping to make my own darkcloth for my 4x5 camera and was wondering what the proper size would be to make it. Is using something like a dark felt from Joann's or wherever else acceptable?
Whatever size you make it, I wouldn't make it dark felt or you'll burst into flame during the summer months. I use a Blackjacket now, which is like a shirt with sleeves for the arms, so maybe someone else will hold forth re proper size.
4x4 foot minimum. White on one side, black on the other, with velcro edges. A light, canvasy material may be appreciated, though you actually want the thing to have some weight because it can become a sail in a breeze... you might think of sewing some little weights onto the four corners.
& I use that thin curtain backing material, black one side, white the other... $10 metre here, mine is 1 metre square ... then I stuck 2 small pieces of Velcro on 2 corners for those windy days.
I use a tubular dark cloth from Lotus View Camera. Silver on the outside and black inside. My only criticism is that it is a little light and flaps about in the wind. However as it is secured to the rear standard by an elasiticated collar I suspect it is not as bad as an unweighted unattached cloth. Whatever material you use I would agree that sewing in weights is a good idea.
The silver outer face reflects heat from the sun but even so gets quite warm in there after a while
Its also waterproof - so use it as a rain cover for the Camera when its set up on the Tripod
There is no right size of Dark Cloth - they need to be big to shut out enough light but small so they don't act as a sail in the wind (I have learned to keep one hand on my Tripod at all times when the dark Cloth is on the Camera)
