Flare from filter or what?

[michael9793]

This weekend I took some photos of a old church with my 165 Schniender wide angle and my Wollensak triple convertible 300mm lens. After developing the negatives along with other negatives from the same trip. I found all the church pictures had what looks like flair on the top of the negative. There were over exposed semicircular area dipping down into the photograph. one negative had one from the 165mm. one had two from the 165mm and one had three from the 300mm. Now I was thinking the 165mm could have been from the extreme rise of the lens, but I didn't do it on the second exposure of this lens. The 300 was further away from the church and no corrections.
The one common thing was I used a orange gel filter. Here is where it gets funny. the 165mm the filter was on the outside and against the lens. the 300 the filter was behind the lens and against it. The over exposed areas are about the same size on all negatives. I have used gel filters on my 8x10 for a long time and have never had this happen.
P.S. the sun was from the left side of the camera not directly on the lens glass.

Sounds more like a light leak than flare. Could you post a few examples, showing the full sheet of film including the rebate?

I will post them tonight when I get home. I don't think it is a light leak because I shot before and after this and did not have the same problem. In fact I shot almost into the sun on one photo and got flair but not like this. I shaded the lens on the next exposure and it was fine. But I will post them all tonight. very nerve racking since I haven't had this before and I'm going to Yosemite in 5 weeks with this camera and the last thing I would want is to come back with a load of negative like this.
