My first test with a 3 perf cameflex was perfect except for the gate flare present in the negative. Just want to confirm this is the case... however the triangle flare isn't vertically/horizontally flipped as the rest of the image. Looks like it's flaring/bleeding into the next frame. As far as solutions...paint the mask? Both sides? Which paint do you recommend? Attached below are the stills, and of the gate, with and without the shutter. Many thanks!
