| Can anyone tell me the guide number for the 64B. It seems like I read somewhere they based the guide # on ASA 25 rather than ASA 100. All searches I have made have proved futile. Russ |

| The back of the Futuramic lamphead has a built-in exposure guide. Set this so the guide number for the film you are using lines up with the point of the ready-light opening. For medium-speed films such as Plus-X the guide number is 90. For high-speed films such as Tri-X, the number is 135. For Ultra-high speed such as Ilford HP5, (400 speed), the guide number is 190. For Kodachrome, the number is 35. Fred. |

| Thanks I was hoping it was higher. I guess the 660 is no better. Russ |

Sorry. I attempted to upload a copy of the 64B guide, but it wasn't legible. Cheap H-P Scanner. Fred.
