What's wrong with my film camera?

I have a canon ae1 and my last few films have turned out like the photo. I was thinking it was a light leak so i tested a film reel but the orange or fading isn't consistent throughout. Does anyone have any ideas, it seems like the orange shows up outside and the camera is fine in indoor lighting?323588_1548328161.jpg

It looks as if you may have a light leak.....check the foam seal round the camera back and also if you have access to it take a look at the state of the cassette you loaded.....was it old stock or faulty.....the cassette would stripe the film in only one place normally outside the camera, but when loaded if the camera was left sitting in strong light a stripe may appear down the exposed strip of film where it winds on to the take up spool. The extent of fogging would depend on camera case, degradation of sealant, strength of light and also the width may change as more film is wound on to the take up spool. I have several older film cameras where the foam in the body groove has disintegrated or gone sticky and failed.

It could be the foam around the window which allows you to check if you have a film in the camera has perished or moved

What Charles said (bornstupix2) as far as I recall the AE-1 didn't have a window to check for loaded film. When used indoors the level of light will more than likely be less and cause little or no fogging, but in bright light fogging will be evident.

The AE-1 has a horizontal running cloth shutter. It looks a lot like the shutter is sticking at some point in its travel. You may be able to see this if you fire a few times at different speeds with the back open.

A few years back I’d say bin it and get a new one but they are now expensive enough that it may be worth getting it serviced.

Alternatively the T70 is a nice camera and quite cheap.

Sorry. I just looked again and with the colour of the problem it will be a light leak. The seals are quite easy to replace on these cameras, just look for Aki Asahi on ebay for pre-cut kits - I just got some for an OM-10 and it only took a few days.

Surely if it was a light-leakage problem, the degradation would be across the whole frame, and/or very blotchy, not just a fairly defined ‘chunk” of the photo...? puzzled by it being predominantly outdoors shots though..!

sorry, only asking...

As randomrubble points out the first time it looks like the shutter is at fault. The second blind is slowing down part of the way across the frame making one part of the film exposed to light for too long, this is indicated by the sharp line across the short side of the image.
You might be able to confirm this by choosing a slow speed, say 1/4 of a second and watching with the back of the camera open, also by listening.
Probably quite expensive to fix.

It is a light leak, not the shutter.

The leak is more than likely around the take up spool.

The answer is to look at the negatives. If the discolouration/lightbleed extends across the perforation area then it is a light leak. If it is only on the image then my bet is that the shutter is slowing down.Grin

Damn.. that makes sense...my money is on a shutter problem, but this is a good point..

Hi there!

I have a Minolta X700. The last 3 film rolls, all different types have caused this to happen to all my exposures. I'm pretty sure that there is something wrong with my camera, just not sure what exactly. Just wondering if anyone has experienced something similar or might know what could be the issue.

Thanks!

The shutter is at fault. The shutter blinds expose the film by travelling horizontally across the film one after the other, the gap betweeen them determines the time that the shutter is open. At 1/1000 second very narrow, at 1/30 quite wide..
Open the back when there is no film inside and operate the shutter at various speeds from about 1/4 second to 1/250 and watch the operation.
(I am assuming from the example that flash is NOT being used.)
