Last year I got myself a Ondu Pinhole camera, and I brought it to India as I went there for vaccation, however after developing the film I noticed what I can only describe as a fog on the negs. This has happened before occasionally and I wonder what it comes from.The humidity in india is something else from what I am used to, and I thought that perhaps it was an effect out of the film being foggy as I shot it (starting fogging as I opened the shutter and let new air in..) if that is probable enough..? I have yet to see these effects when using my Holga WPC120 (plastic) and thought that the wood in the Ondu might be a disadvantage? I dont know, any theories or knowings??? Not very much findings on the web regarding this. Here are three examples, notice the edge and corners, the edge of one of them is enlarged also.
