Hi folks,

Got back yesterday from a ten day trip, mainly to Wyoming (Yellowstone Park) but with some time also spent in Utah, Idaho, and Montana. My walking around camera was an OM-2n loaded with Fuji Superia 200 and I also traveled with an OM-4 loaded with Fuji Velvia (50 ASA) for landscape shots using a tripod.

I wanted to only risk the film being zapped once as carry-on luggage on the airplane so I planned to mail the exposed rolls back two at the time to a local processor. Well, when I started to load the third roll of film into the OM-4 I noticed that it was set for ASA 80, not 50. I thought about this for a few minutes and finally decided that, in a careless moment, I had set the speed incorrectly when I loaded the first roll of film on the trip. So, I added a note with the first two rolls asking the processor to push it 2/3s stop and dropped it in the mail hoping that I had guessed right about the source of the problem.

Only four or five shots into the third roll I glanced at the ASA dial and it was off the 50 setting again! This time I remembered that I had just added one stop of compensation when taking a picture of a waterfall so I tried rotating the dial again and, sure enough, the film speed changed. I fiddled with the dial a little more and found that, most of the time, I could set the exposure compensation normally but occasionally doing so would change the film speed.

So, has anyone else experienced a problem similar to this and developed an easy cure? OK, I know I can discipline myself and check the film speed anytime I make exposure compensation adjustments but I'd rather concentrate on other things. I'm hoping that someone has found that something like the judicious application of a drop of oil will fix it.

BTW, I'll be scanning the photos from the trip over the next several days. It doesn't appear that I got any real "wall hangers" but I'll post a few of the more interesting ones to a web site anyway. Some of the List members from overseas might find the Yellowstone area interesting.

Later,
Johnny
