I am curious as to how many here keep the dark cloth over their cameras at all times. Indeed, how "necessary" is the continued use of your dark cloth in order to prevent fogging of the film when removing and reinserting the film holders and dark slides? Is the continued use of the dark cloth dependent upon the brand or size of camera that you have ( or perhaps the material that is used to make your camera ), the age of the camera that you use, or even the type of film holders that you are using? Does the presence or absence of a bail back influence your decision? A friend of mine and I are discussing the necessity and advisability of keeping the dark cloth on one's camera at all times. Thanks for your help and the details of your experience.
