As I mentioned in another thread I managed to open the tank whilst devving some colour film and nearly all the shots were ruined.... But the second roll went ok, or so I thought. All of the shots have some marks/lines/fogging on them like this

Now, I'm talking about on the right hand side here not the messy bit on the left ( :D ), any thoughts? Have I managed to get the film creased on the roll or is this fogging caused by a light leak? Or is there another more mysterious answer?

Thanks

Andy
 
Assuming this was from your C330 we can rule out shutter problems, was the problem the same on all frames or just this one? It looks like it could be a light leak of some sort.
 
That definitely looks like a light leak - and a bad one. The pattern looks odd though - as if the film was crinkled somehow. :(
 
If it is a light leak its not from the camera, the roll of T-Max I put through is fine.

The problem seems to be on every frame but not always the same pattern (although some are very similar)...??
I'll pop some others up tonight with different look to them.
 
looks like a bad case of .aurora borealis ,,,,,,,,well you were ooopp north :D

or a light leak ,,,,
 
Did the film itself look okay once you'd developed it or did it look damaged?
 
Looks like a massive light leak. I had a mild version of that with the automat as I loaded it in broad daylight and took an age to do it.

I'd also put a battery powered light into the film compartment and check to see if there is any light visible when it is closed up.
 
It's definitely not the camera... Its had lots of rolls through it with no problems and the film that went in afterwards was fine as well.

My thought is that it might be from the Jobo tank. I had a problem with the first film I devved when the collar that you push down to seal the lid on the tank, popped off. I'm wondering whether the thing doesn't quite seal correctly..
 
Do the light trick with the jobo thingy. That should tell you whether it is light tight or not. I'd imagine the tank thingies or seals on their own are readily available.
 
I shall. I'd like a larger one anyway so I can do 2 x 120 rolls at once.

If by hipster you mean someone getting on a bit and has dodgy hips then I agree.

I've always been hip.... I'm natural cool and trendy with a certain classic insoucience and rugged good looks that make me almost perfect. At least that's what the CMS tells me. ;)

Oh look....there goes another squadron of those flying pigs..:whistle:
 
I recently had a similar problem with a Jobo tank.

The starting point was that when I emptied the tank, a small part of the central core inexplicably was lodged between the outer part of the lid and the inner funnel. So I took out the inner funnel and replaced it once the offending item was removed.

However I still had light leaks - mostly in the film nearest the top if more than one was loaded. Eventually I realised (Doh ......) I had fitted the funnel the wrong way round so the spout was pointing up instead of down and therefore did not join up with the central core to form a seal.

I can't really believe that I did that, but then again if a developing mistake can be made, I've made it.
 
Sorry if this is a really dumb question, but I'm intrigued - what's the advantage of these Jobo malarkeys over a normal dev. tank?
 
If the Jobo spiral is anything like the Paterson one, the pattern looks like it might be from the plastic mesh on the edge.
 
Here's a couple more

Annoyed as I really rather liked this one.

The Jobo ones are designed to fit the Jobo CPE 2 tanks. I'm going to shoot a roll and use the Paterson tank to test out the theory that the Jobo is trousered.

I'm beginning to think the same.

Jobo tanks are designed to be used with a Jobo processor which automates two of the variables of film processing - the temperature (the processor has a heater and thermostat) and the amount of agitation (the tank is constantly rotated by a motor).

Jobo kits are most commonly purchased by those who do colour processing, because time and temp are more critical for colour than for B&W. Once you have one you can use it for B&W as well, but they are a bit expensive to buy just for B&W
 
Hi Andy, if it's a problem with the dev tank I'll happily refund you a bit on what you paid for it, it's only fair.

There's nothing wrong using Jobo tanks for hand processing, they're not specifically designed for use with the CPE or hand processing, they're just tanks.
 
^^^ True.

@robhooley167 No need for any refunds mate, it might well be my hopeless cack-handed technique that's at fault. I've put a light in the tank and I can't see any obvious signs of a leak but the collar does seem to be a little insecure when pushed on. I will carry on experimenting though. I need a bigger tank anyway as I want to do 2 reels at a time.
