I have couple of dark cloths. They work well with smaller formats, but 8x10 is too big.
My best dark cloth has kind a elastic neck that stays nicely on the camera back during focusing. No way to stretch that around the 8x10 back
Other, classic style clothes are all too small. So I am looking for some source for good dark cloth, preferably on EU area so that buying is easier.
(last option is ofcourse DIY, but I wouldn't do that)
