Film developing
O.k I"m very familiar with shooting 35mm film, ( I do B&W) developing,
making prints in my darkroom so I made a plunge and bought a Rolleiflex camera medium format (dated 1955) and I got it today and the ASA only goes up to 200 speed and I already ordered some 120 Ilford film at a speed of 400, now the question, how should I process it, I usually use D-76 and for that matter I"m gonna put the camera on 200 speed and shoot away.Anything I should do special in shooting or developing.....I didn't relize that the ASA only went up to 200 speed....I'm learning....ever so slowly....thanks for any info Tina |

The true speed of many ASA400 films when exposed and processed for normal photographic purposes is usually 1/2 the listed ASA, or very close. For example, testing with my densitometer showed that 8x10 HP5+, which Ilford calls a 400 speed film, resulted in an exposure index of 200. -Peter PS I have a 1953 Rolleiflex Automat TLR. If you have trouble focusing, you might seriously consider a Maxwell bright screen. |

If that's what you mean I'm going out on a limb and claiming you can just ignore the meter. Use a handheld meter. Or if you really want to use the built in meter then set it at 200 and see what combination of F/stop and shutter speed it wants you to use. Then either close the aperture one stop or change the shutter one speed faster. OTOH if the camera is some how coupled to the meter and you can't work around it then I'd suggest just trying the first roll with no changes. You really should test your setup to find out what your true film speed is. Nick |

My 2.8E goes up to ISO-800. Assuming there is such a limit just halve the exposures given by the meter for ISO-200, that is, use half the exposure time or the next larger stop (say f/11 if it reads f/8). I also suggest using a separate exposure meter. Although the meter in Rolleis is pretty good they are getting old and some may have bad cells. As far as processing, development time changes the contrast, it can not be used to compensate for exposure. While film is often "pushed" to a higher speed by increased development this really does not change the film speed, it only increases the contrast of the low exposure areas to make them more printible. You may find that shooting the film at a slightly slower speed than the ISO-speed will give you better shadow detail. However, Ilford does not use the strict ISO method so the box speeds are already adjusted somewhat in that direction. Adjust the exposure given by the meter and develop normally. Ilford's development recommendations for its films are also adjusted for a compromise between diffusion and condenser enlargers so the negatives will print on either with minimal contrast adjustment. Write me privately if you have other Rolieflex questions (or here if you prefer but I don't check the news groups as often as I should). -- --- Richard Knoppow Los Angeles, CA, USA |

[My] Rolleiflex's ... ASA only goes to 200 speed ... [I am using 400][.] [What should I do?] If your camera has 'manual' metering, the needle reading is transferred to a small set of concentric dials and the metered speed/f-stop combinations are then read from the dials, you are in luck. The exposure dial on your camera may go past 200 - most go in a full circle. If so then set the speed to where 400 would be. The meter itself cares not a twit about the film ASA. -- Nicholas O.
