Plaubel Makina 67 - edge of frame looks odd

[buzzski]

Hey there - I finally picked up a Plaubel Makina 67 that is very fresh and it arrived today. So I ran a roll of P160 through it and dev'd to check the camera. It all seems good but I'm seeing like a secondary rebate / image around the edges of the frame. Is this normal? None of my other MF cameras have displayed this and I am aware the Makina 67 has it's quirks but thought it worth checking here if anyone has seen similar - many thanks in advance!

Could be a feature, not a fault.


Sorry that wasn't helpful.

 

[Matt Fattori]

My Makina negs have never shown anything like this so it's certainly not normal. I don't know what it is.

 

[buzzski]

And in positive

This is how it looks in a scan / print

 

[Matt Fattori]

That's very odd...could there be a problem with your pressure plate?

 

[buzzski]

The pressure plate doesn't sit al that even so I too am wondering if that's the issue

How can you tell that with the back closed??

You have a light leak from the bellows.

 

[buzzski]

Impossible to tell with the back closed but when it's open I can see the plate sits higher at one side than the other. How it sits when closed however, I do not know. I have no experience of folding cameras - is this indicative of a light leak from bellows?

 

[nwilkins]

it looks like light is getting in somehow from an angle, so bellows leak could be the problem. or mysterious flare as happened to me one time (but never again): (there was a url link here which no longer exists)

 

[Dr Croubie]

Is it on all 4 edges of the frame, or just 1-2?
If it's on 1-2, that suggests a light leak at a high angle that it would 'get under' the frame edge (when scanning, I've found shots taken with WA lenses have larger frames than normal lenses, because of the higher incident angle).
Light leaks do tend to be very uneven though, you should see some kind of flare or something in the image.
But if it's all 4 frame-edges, then I'd be thinking pressure-plate problem, no way a normal light leak could be that even.

If your Plaubel 67 is like my Wide version, the shutter release is concentric with the film advance lever. Is it possible that you are grasping the camera in such a manner that you're using the film advance lever as a fulcrum to support the weight in your hand, and that when you release the shutter the film then advances slightly during the exposure?

I've certainly never seen anything like what you are experiencing with my Plaubel.

Looks like a reflection from the film gate. Is the edge uniformly matte black?

 

[itsdoable]

I don't think it is film gate reflection, as that should over expose the film there.


It looks like a double exposure, a fog exposure super imposed on the picture with the film gate shifted a small amount. Your attached image (mak67002.jpg) certainly looks like that, the strip at the top looks like it was not fogged.


Check for pin holes or light leaks in the bellows or shutter blades. My guess is that the film was fogged a tiny bit imprinting the film gate, and the film shifted a bit before you made the exposure.

Looking at your images it appears that the double edge effect fades out along the long edge of the film (as seen underneath the frame number) and is only present at the ends of each frame, so perhaps the film is lifting the pressure plate and causing light to creep along the edge. So is it a very old roll of film used for testing your new camera that has seen a lot of temperature changes and perhaps taken on an extreme curl that is strong enough to lift the pressure plate? I'm certain it isn't a light leak in the conventional sense of coming from the bellows etc as it is far too neat and tidy. But a weak pressure plate spring has to be another possibility.
