Equipment used was a recently CLA'ed s/s M3, 90/2.8 Elmarit with hood, Leitz UV filter, and Portra 160NC colour negative film. Evidence is at http://jahudson.tripod.com/TEMP/Frame_01.jpg http://jahudson.tripod.com/TEMP/Frame_02.jpg http://jahudson.tripod.com/TEMP/Frame_01_left_Frame_02_right.jpg Frame 02 shows a distinct light streak up the right hand side of the image, at least one shade of gray lighter than the adjacent areas. Frame 01 does not show a corresponding streak across the top of the image. The split [third] image shows the streak from frame 02 but it does not extend back to frame 01. The frame immediately adjacent to frame 02 [not shown here] shows no evidence of the light streak. The lens was mounted on the body after the film was loaded in a darkened room [frame 01 was the first frame shot] and was removed after taking frame 02. The time of day was the late afternoon last Sunday and the lens was pointed away from the sun at all times. Frames 01 and 02 were taken within the space of less than two minutes. No other frames on the roll of film show any evidence of this light streak. If the streak on frame 02 is not a light leak is it possible that it arose through processing? Any and all comments will be gratefully appreciated. John Hudson
