analog-photo Posted August 14, 2011 Share #1 Posted August 14, 2011 Advertisement (gone after registration) Hi! Recently got six rolls of Portra 160 VC developed at my local lab, fresh film bought a month ago. All rolls had a light damage on the starting lead - a vertical line, zigzag in shape (i have no scanner so I can't provide an image). On all films the light had gone through the emulsion and also made a trace on frame nr 1. I've used this lab for several years and know they always make high quality work. They say they have not changed anything in their procedures. Looking closely on the film can and comparing the light lock with an older roll of Portra 400 (from last year) it looks as Kodak has changed the material? The 400 roll has the traditional velvet looking light lock. On the 160 it looks more like some kind of plastic foam. Anyone with the same experience or knowledge about any change of material in Kodak film cans? Lars Link to post Share on other sites More sharing options...

Doc Henry Posted August 14, 2011 Share #2 Posted August 14, 2011 Lars, I just watched two rolls 160 VC and 400 VC The felt that protects the film against the light is the same I think it's rather a problem with the camera if it excluded a problem with the development by the laboratory What camera do you have?

analog-photo Posted August 14, 2011 Author Share #3 Posted August 14, 2011 I have a M7. The same lab developed a couple of rolls a month ago without any trace of light leaks. But I'll take a new debate with them... Lars Link to post Share on other sites More sharing options...
Doc Henry Posted August 14, 2011 Share #4 Posted August 14, 2011 I also have an M7 is it possible to have a picture of the problem on the film ? Have you an iPhone or other APS ? Henry Link to post Share on other sites More sharing options...
Eastgreenlander Posted August 14, 2011 Share #5 Posted August 14, 2011 Canister perhaps exposed to direct sun light? Link to post Share on other sites More sharing options...
analog-photo Posted August 15, 2011 Author Share #6 Posted August 15, 2011 Some more details to the mystery; I have two M7 bodies, the films show exactly the same light damage from both. I enclose pictures taken of the films, hopefully you can see what I mean. I consider myself as an "experienced amateur" - I got my first camera when you had to learn the difference between ASA and DIN. And I have used several Leica for the last 15 years. So, I know the procedures of loading and unloading the film. I had a long discussion with the lab today, none of us had seen this kind of light damage before. They also examined all films from other clients they had developed the last days, none of them shows the same light traces. The only possible explanation I can think of is due to the fact that I always rewind the film fully into the film can. If the light lock isn't tight, this could maybe cause this. But, as I said, I have never seen this before. Therefore my question if Kodak has changed anything in their production. Link to post Share on other sites More sharing options...
earleygallery Posted August 15, 2011 Share #7 Posted August 15, 2011 Advertisement (gone after registration) Is this just on the leader? I take it no frames have been spoilt? If it was a light leak on the canister I'd expect it to be straighter, the line appears to be on quite an angle. I'd suspect some issue during processing - but does it matter if it's not affecting any other part of the film? Link to post Share on other sites More sharing options...

I'd suspect some issue during processing - but does it matter if it's not affecting any other part of the film? If it was only that I could live with it. But the incoming light has been strong enough to go through the film base and produce a line on frame nr 1 on all rolls. OK, I could simply wind an extra blank when loading the film, and still have 36 frames to shoot. But it's annoying. Lars Link to post Share on other sites More sharing options...
too old to care Posted August 16, 2011 Share #9 Posted August 16, 2011 I think that it is unusual that we can see a wavy dark blue line with a distinct pattern on all the rolls of film in the effected area. I have not shot any 35mm Portra for awhile and I did not have this problem when I did. What does the felt on the canister look like? Is it still a fine felt and a very tight fitting? If Kodak changed the felt to another material than this can be explained, if not? Wayne Link to post Share on other sites More sharing options...

analog-photo Posted August 18, 2011 Author Share #12 Posted August 18, 2011 no news from Lars Well, well... I've taken two rolls today ("urban exploration" - a closed former paper mill, I've asked the lab to scan the films as well. Hopefully I can publish some pictures later on) and left them to the same lab. One Portra 160 VC from the same batch as above and one 400 VC that's been in the fridge from last year.

analog-photo Posted August 22, 2011 Author Share #13 Posted August 22, 2011 Today I collected the two rolls. No traces of the previous light leakage. I guess it was something that happened in the lab. But the lab denies. Anyhow, to finalize this thread, I enclose some pictures from the these last two films. It is from a paper mill located close to the city centre of Mölndal, which is a small town adjacent to the city of Göteborg in Sweden. On this spot paper production started in the mid 18th century and continued to 2006 when the mill closed. Now the city will start a development project for the site. Thank's for the interest!

250swb Posted August 23, 2011 Share #14 Posted August 23, 2011 With the frame number being 00 in the examples you have scanned my guess is that you are being mean to save film. Wind it on further, loose a frame. Steve Link to post Share on other sites More sharing options...

Wind it on further, loose a frame. Steve No ambition to save film, when loading a M you can only do it in one way. Put the lead end in the uptake slot, close and fire two blanks, wind once more and you're on frame nr 1. It's fool proof and as I've said earlier; I've never experienced this kind of light trace before. Last two films was OK. Lars Link to post Share on other sites More sharing options...
Doc Henry Posted August 23, 2011 Share #16 Posted August 23, 2011 Lars, It is good that the problem is resolved ! i am glad for you ! I think for Portra 160 , the colors are not like the pictures of Portra 160 vc i have. Sorry to to be frank ! What is the scanner of the laboratory ? I think you should have your own scanner Best Henry Link to post Share on other sites More sharing options...

I think you should have your own scanner Best Henry I don't know actually. Think it's a Fuji pro equipment for labs, they can choose to copy the scans they make of the developed film for prints to a CD as well. The scanned copy to CD is not corrected by the lab (which is obvious when I compare the the prints with the picture on the screen, I have a MacBook Pro, no Photoshop or any other software except what you can do in iPhoto. Which i impressive compared with the PC I had earlier...). Someday I have promised myself to buy a scanner. Lars Link to post Share on other sites More sharing options...
Stealth3kpl Posted August 23, 2011 Share #18 Posted August 23, 2011 I keep my Tri-X in a plastic bag because of Portra's tendency to leak light everywhere Pete [ATTACH]274538[/ATTACH] Link to post Share on other sites More sharing options...
