Strange low contrast in middle of negative Fuji gsw690ii

[Andrew O'Neill]

Have you looked through the back of the camera to see if the leaf shutter is actually closed? I had a lens on the RB that wouldn't close completely... It acted like a pinhole camera.

Okie doke I have a film in it currently so will look when I’ve finished the roll

A partially open central leaf shutter would illuminate the entire frame, just like a diaphragm.

My guess would be a really faint light leak. Try leaving the camera out in bright light after firing the shutter with a lens cap.

Yes with both make eye and loupe on two different light boxes. Photo attached of marked spot

OK that's what I saw as well although in the one with the now attached red circle the issue looks fainter that in same scan you showed without any circle but I don't know why except that the second scan of the original meg may be slightly different

The designation "GSW" identifies the model with an extra-wide 65mm lens. Some illumination falloff is inherent to this lens out toward the corners and far edges, with the center appearing a little brighter. This effect is more apparent in a high contrast scene like you provide than a lower contrast one. You also have a somewhat higher contrast film involved (Ektar). Nothing wrong - just get used to it, and be aware when it might pose a problem versus a creative opportunity.

Light leaks look nothing like that.

Experiment shooting with different f-sops (at corrected speeds) an evenly illuminated neutral target, like a large sheet of gray matboard. I suspect you'll find that the very widest f-stops exhibit more falloff than smaller stops. But I don't own this actual lens; my own cameras are
GW690's (ii and iii) with the 90 mm lens, which has very little falloff.

The OP's issue does appear to produce a faint purplish mark where he indicated by means of his red circle How is this explained by your answer?

Thanks

I can't tell much from that web image. I'm very familiar with the film involved. But properly shading a wide angle lens is tricky, and it's entirely possible that a certain amount of flare was involved. If there was condensation or lens haze involved, then much or all of the image would be fuzzy, which is not the case.

Why would portions trend purple? (looks pinkish purple on my screen) - it's exactly what I'd expect when the usable range of Ektar starts getting bounds. But maybe that was truly there in the scene, and simply exaggerated a bit by the nature of lens falloff in relation to the native film curve.

Otherwise, I'm reluctant to repeat for the upteenth time why Ektar needs corrective color temp filtration at the time of the shot. The cyan shift in the sky is quite evident. Use the search engine to look it up, or under my own posts in relation to Ektar.
