My Motormatic Kodak green needle won't move off automatic and I would like to do some B&W 400 film in it.
So it has a shutter speed selection of 40-80-125 & 250. The selector for the ASA is real easy to change so if I added a red filter how far down would I have to move the ASA to compensate for the filter. I was figuring on a bracket between 125th sec & 250th.sec shutter speed.
The meter is alive and I have used this camera before with good results. All on Auto.
Thanks
Ron

I had a bad experience using a Red R60 filter with the Nikon FE and leaving the TTL auto exposure (aperture priority) do its thing. Quite underexposed. I have since found this advice in an FM3A user manual online:
"Withthe FM3A, the filter factor need not be considered except with the R60 filter. Compensate
exposure +1 EV when using the R60."
Somewhere else I think I saw advice to compensate 2 to 3 stops for a Red filter
Ah, found the note I made of it:
"Try opening about 1/2 stop for the yellow, 3 to 4 stops for the red. Outdoors they'll need a bit more exposure in shadow areas than in open sunlight because the light will be more blue."

I found the manual for it on the Buckus site. I did find out how to take it off automatic & why the shutter speed wouldn't go under 125th sec. To go under that the asa has to be set bellow 160th sec or flash, that gives me a choice between 40-80- 125 &250th sec. I think that I can work with 125thsec as the camera closes down to f:32.
I think what I will do is try some different settings and write them down, blow a roll, then try a roll for real?
The camera doesn't have many options so I can't screw up too bad?
I just took it out side to take some light readings from the camera and my Gossen hand held, they are pretty close. Say I got a reading of 22 @ 250 @ asa 400. Then I held the filter over the sensor on the camera and came up with about f:5.6. So I am guessing if I set it it there I will be pretty close?
We will find out by this weekend?

The yashica-guy.com site has a good filter factor list that you can print out, laminate, and carry with you for reference. I use it whenever I'm out with my Vito B. An orange filter is a factor of 3, so I think a red filter would be around 5. This translates into ASA 100 becoming ASA 20.

Thanks Dan, I haven't had time to download it yet but have read some of it. I found that I was on the right track, but the wrong train.
I am taking my G-daughter back to Kalispel Mt in the morning and I plan on taking a few cameras plus filters for the Motormatic. Hope to get some shots to post here?
I will download the info soon, makes me feel pretty good as I was close to what it says to do, I may get one out of three right?

Well, I cheated, I have a problem reading instructions sometimes. Here I was , 150 miles from the instructions that I printed so I done the next best thing? I held the filter over the light cell, then put it on the lens and used the readings that I got. Sort of worked.  RED FILTER  YELLOW FILTER    |

Montana is beautiful in August. The smell of wild fires and Buffalo in the highway.   |

Things have changed there Larry, no more Ladies in long skirts or horse & buggies. Now it is big pickup trucks{w/dog in back} and girls in short shorts. Heck, it has grown so much that I couldn't even find the old downtown. The courthouse sits in a small tight traffic circle. No way to get a good pic of it. This wall art is the only thing that I took a shot at, as it was too close to a carwash I had to 'stitchit'. Note the spelling on the sign.  |

Ronald everything changes the secret is hanging out long enough to find the secrets.... I am still finding them in Clarksville. Town torn by the War of States Rights and the infusion of all the G.I.'s from WW II on. I like that as I have seen worse on a wall. |

Compare---- Kodak Motormatic B&W w/yellow filter to Voigtlander CLR w/skylite filter. Both with 400 asa film. Kodak B&W and Fujifilm color. Flathead Lake, Montana. Voigtlander CLR  Kodak Motormatic  |
