Learnings from testing an old camera with expired film stock
Earlier in November 2025 i repaired a Canon Eos 10 camera from the 1990s and then took it out to test it with a roll of Kodak 400 asa film. You can find the repair here: Canon EOS 10
Canon EOS 10
The caveat is that the film expired in 2005, 20 years ago. As a result I have overexposed it at 200 asa to compensate for the deterioration in sensitivity from such a long storage period. It may work, it may not, previous tests on a 200 asa film showed that a one stop over exposure was quite sufficient. Fingers crossed 🤞 on this one.
I don’t expect anything much, I expect quite a bit of grain and a definite colour hue over the entire roll. Who knows there may be nothing on it at all 🤷♂️
I’ve sent the roll off to our local photo guys in Leicester : Classic Photo Supplies and hopefully something will be on the medium res scans that i have requested. If there are pictures below, then there was some success, if not, enjoy the blackness.
Well, the scans are back and to be quite honest this one is a bit of a disaster. As stated the film is over 20 years out of date and there appears to be two problems here. Underexposure is one issue, I over exposed this by one stop but I don’t even think that is enough. If I’d overexposed at 2 stops though I might have improved the brightness, the already heavy grain would have been even more exaggerated. I think it’s fair to say this 400 asa old film stock I have is passed its time and not really fit for use.
Look at the grain at plus one stop overexposure
Hello what’s that line?
Heavy grain and a magenta cast
That shutter sync problem
Slower speed, shutter ok
So. Though the results were not good and I have now realised that this old stock film is probably best for me to use as test film only. There is heavy grain, a distinct cast over the film and a quite obvious shutter curtains sync issue. These frames above a shutter speed of 500 seem to be the issue, and that is where the shutter speed has not synced the curtain, it’s definitely running slow. The film has been beneficial in identifying an issue in this part of the camera. I will now do a CLA on this camera shutter assembly to try to remedy this issue. I wasn’t using flash here, it was a dull cold English Sunday afternoon.
This is an old camera that has been sitting idle for many years, it may sort itself out after a few more rolls of film, however I can do something about it now. And this is really a lesson to be learned for anyone buying old film cameras, they do need that little bit of tender loving care to get them back into a good working condition.
I’m pleased I’ve highlighted this issue, I will get the work done to improve the shutter sync and then run another roll of film through it.
Maybe now is the time to buy a shutter speed optical tester. That may save me a bit of expense on processing costs and will also allow me to make these checks before committing to film.
Just walking around the east coast of Norfolk Uk. Seaside places are usually a hive of activity during the summer months and then winter hits and everything then shuts down.
There is an eeriness of silence everywhere and I think black and white photos highlight that feeling just perfectly.
Ventured off to the East coast for a few days.. just arrived in Great Yarmouth
We’ve taken a drive up the A47 today and are currently residing in Great Yarmouth for the night. Tomorrow we move next door for a few days to Hopton on sea for a little rest and recuperation.
We arrived here just as the sun was setting, so just the one picture to be cracking on with.
Great Yarmouth earlier today
Hoping for a little stress free time away from it all as everything has been just a bit too full on lately.
An old EOS 10 was in need of attention. And I was able to lend a helping hand
Here I have a Canon EOS 10, a quite superb little camera. The date code within the film barrel is HE1213, indicating that this camera was manufactured in December 1990. At the time of manufacture this camera sat firmly at the top of Canons camera tree only surpassed by the EOS1 professional camera that had been released the year earlier in 1989.
My EOS 10 35mm SLR
This camera was amongst a selection of cameras and equipment passed on to me by a good friend and professional photographer as can be seen here: Cameras…i need more!
Here is a little history regarding the EOS 10
The Canon EOS 10 is an autofocus 35mm SLR introduced in 1990. The model name was EOS 10S in the Americas, and EOS 10QD in Japan. There was a commemorative metallic-silver version introduced in 1991 to mark Canon’s 60 millionth 35mm camera sold.
The improvements over the original EOS cameras are a newly improved autofocus sensor. Focus modes include One-Shot AF for non moving subjects and AI Servo AF for moving subjects. It is able to detect and switch automatically between the autofocus modes. Shutter ranges from 30 sec. to 1/4000 sec., with B. X-sync at 1/125 sec. Similar to the EOS 750, is has a built-in flash with a guide number 12 (at ISO 100). It uses one 2CR5 lithium battery and weighs approx 625g for the body without battery.

Assessment:
One of the nuances introduced on this camera was the barcode option. Introduced at a time where barcodes were starting to creep into our life, in a knock at Minolta and their use of specific expansion cards for specific scene settings, Canon thought it would be good to utilise barcodes that you could scan, to automatically set your camera with these options without expansion cards. Needless to say it didn’t take off and was soon dropped from later camera production. It was a sign that the development teams were looking for advancement opportunities.
That barcode mode – soon forgotten
These cameras are available at fairly reasonable prices now partly due to the dreaded sticky rubber grip issue that tends to send buyers running for the hills, god knows why, it’s an easily remedied issue that just takes a little time and patience. I did a previous post about cleaning these cameras here: Sticky, Rubber camera grips it’s all down to the polymers in the Vulcanised rubber breaking down and reacting with hand sweat and other stuff. Have a read, and never throw away a camera just because it’s sticky.
This camera has some stickiness but it is not an advanced case. It will still be cleaned in the same manner, to prevent it developing any further.
The camera is just a bit dusty and in need of a good clean. The mirror is dusty and needs cleaning, a blow out of the interior should suffice as the shutter blades are opening and closing with no issue.
Inside clean shutter blades are okFilm plate unmarked Mirror is dusty and requires cleaning
The battery is a lithium 2CR5 cell. The battery chamber is clean with no signs of battery contamination, this is a very good sign. When placed into the camera the screen comes on, is clear with no damage. A lens put on the front confirms that auto focus can be achieved and the camera fires and winds as expected.

To be quite honest, there doesn’t seem to be a lot wrong with the camera. It really seems to be just a clean and maintenance issue. I’m going to give the camera a thorough look over, dust and clean, a thorough clean of the external rubber and finish it all of with a good exterior body treatment. I will then run a roll of used film through to check the DX reader is working, as well as the transport system. Fingers crossed nothing major raises its head during the repair process.
Repair:
Straight in and at the cleaning, and to be honest the rubber wasn’t too bad. I only used two applications and not a lot of dirt came off on either. After it has dried, it does feel a great deal better.
Heavy cleaning, wasn’t that heavy
The mirror has cleaned up nicely, so has the prism above it, however whilst in there I noticed that the mirror damper felt was failing, so this I have now removed and will have to replace prior to using as I don’t want to cause any further damage.
The missing damper felt area, highlighted in red
I’ve had to order some new material that will hopefully be here shortly, as my supply, as is always the problem lately, is in storage with all my other gear pending this house move that will probably never occur. it’s a real pain in the butt not being able to access your most required kit. Hey ho.
The light seal has arrived, and so I start by getting the damper felt put in place. First I cut it to size, remove the sticky back paper and just wipe the sticky bit with some water, this allows me a little more time to reposition it before the adhesive does its work.
Cut to sizeDampen the adhesiveThen put in place
Below is a very small video with me putting the camera into manual mode on a single exposure setting to test the actual worth of the damper foam.
All working fine
I’m happy with what has been done so far.
Strap cleaned and restored
I’ve even given the neck strap a good buff up, the rubber on it was almost white rather than black, a bit of a clean and a polish and it’s now been restored to it’s original glory.
With the new damper in place it’s now time to run a film through it, I have an old test film I use for this purpose, I’m going to set the camera to its highest shutter setting and just run the whole roll through in quick succession to check the transport and rewind.
And here is that test, it went super fine and the full roll rewound at the end.
Transport works just fine
I’ve tested all settings, shutter speeds and functions including the flash and all is as it should be. I’m happy to say that this camera appears to be in full working order.
Now for the final clean and presentation.
Result:
Well, a little bit of car cockpit cleaner has done wonders. It looks beautiful and has a nice aromatic smell as well. I know I’m biased when it comes to cameras but I think this is an absolute beauty.
All polished and looking fine
Covered from all angles looking resplendently clean and tidy
I’m really pleased with this camera, I’m heading out later today to watch a relative play football and I’m going to take this along to grab some snaps with an expired film from 20 years ago. It will be a good final test of the capabilities of this camera, and should finalise its renovation. It’s been a great camera to work on and is yet another worthy addition to my collection. I will post the photos here when they are finalised. Canon Eos 10 test shots
Thank you all for passing by, it’s always most appreciated.
How did the old film trial go? Come in and take a peek.
I posted earlier today Well, that was most enjoyable! Regarding popping out for a morning stroll and taking a 48 year old camera with me to shoot a roll of film that had expired 20 years since.
The camera
At 20 years old, the roll was an experiment where i exposed at normal settings, +1 stop overexposed and +2 stops overexposed. I obtained 39 exposures, always possible from a 36 exposure roll, I won’t bother you with them all, just 2 from each exposure range with a brief description. Don’t expect fine art here, it was a snap session to test a number of factors and to see how the film has deteriorated over time.
These pictures have not been retouched apart from having a frame put around them. They are as scanned, for authentic representation.
200ASA
The advertised, original roll ASA rating. Very low expectations and it didn’t disappoint.
Extremely underexposed
Again under exposure, and a brown hint
At 200ASA the shots were certainly under exposed. The pictures have a cast over them and after development there is a lot of curl on the emulsion (Age) and the base of the film also has a darker tone, creating that yellow brown cast.
100ASA (+1 stop overexposed)
The best two exposures represent the first overexposure of one stop from 200ASA to 100ASA.
Pretty nice overall exposure
Again nice exposure and highlights very prominent
At 100ASA everything seems quite acceptable. There is that hue over the film still, and highlights seem quite prominent. Grain is present but not too distracting.
50ASA (+2 stops overexposed)
If you work by the suggested standard of one stop of exposure for every 10 years then this should be the standard. However I’m not so sure.
Nice colour, highlight prominent and quite a bit of a yellow hue, would need adjustment post processing
Could have been taken in the late 70s or early 80s
So with the exposure at 50ASA we have now introduced quite a bit of grain, a yellow hue and quite prominent highlights. I’m sure all of these pictures would post process fine if run through photo shop or light room. But to be quite honest I love that retro look that they have.
For me i’d probably aim at the 100ASA +1 stop of overexposure on the remaining rolls I have, I believe that would be quite enough, however even the 50ASA option is not too bad though you would require a lot of post working and you’d have quite a noticeable size grain.
Horses for courses as they say, but I’m going down the +1 stop overexposure route for the next film.
I found a little local photo store here in Leicestershire called Classic photo supplies, who specialise in all film processing, supply, printing and Sundry items. The owner Brett invited me in and we just chatted classic photography whilst my film was developing. He’s a super guy, and I’m all for supporting small businesses, so this is my new go to lab. The scans were done and over to me by email within an hour, super quick service. I’ll pick the negatives up in the week when I drop off another film to be developed and scanned.
Thanks for passing by. As always I am honoured by your presence.
Now I’m not a Cat person as such and you are not going to find copious amounts of Cat pictures on my pages. However, tonight is different as I required a suitable model to just test the new camera, so here I introduce “Tabs”.
There is a story around Tabs, we purchased our current house about 8 yrs ago and she featured in all the pictures that the estate agents took of the garden. We thought she was the sellers cat but this is not so, she is a Feral soul, and this is in fact her territory and we have moved into it. It’s her property and not ours.
She chases all foxes and other cats from the garden and is an excellent mouser, she had a lovely relationship with our little dog that passed away last year, she likes the hedgehogs and she loves company.
But she will never enter the house, we have all doors wide open and she remains outside, she is more than likely a domestic cat that chose to go feral.
She is fed numerous times a day by us, it’s our way of paying her rent to use her garden. My new camera was purchased as an early present from my lovely wife, and needed a quick test, and Tabs was there in the garden mooching around as she wanted feeding. I therefore just rattled off a few shots to do some basic testing of the camera. I’m really happy with it, but there is still a lot to learn about it.
Here are four photos taken whilst I was visiting the signal box at Melton Mowbray. This train line is between Leicester and Peterborough and has a number of Victorian era signal boxes still in use today. All pictures taken with my IPhone 14 Pro Max.
I purchased this camera for just £8:00GBP, damaged a few weeks back. It’s a 9mp camera from back in 2005. It was the simplest of repairs and that post can be found here: Fujifilm Finepix S9500. It’s a lovely little camera, and today we took my 11 year old nephew to Liverpool for the day, to celebrate his birthday and to do a stadium tour of his favourite team. And i took the Finepix S9500 to see if it worked, and I’m pleased with the results. I got some looks of sympathy when I pulled this one out of the rucksack, but who cares, I fixed this, and it works. Yes your big flash fandango cameras are lovely, but to be honest I’m just interested in enjoying my time out with family and getting some snaps. Here’s a selection from today. Nothing special, as I said just snaps.
Today I took the wife to have some dental treatment. Whilst awaiting for her to rise from the chair, I decided to take a walk around the local park and surrounding areas to take some pictures. I only had my iPhone with me, so I snapped away. Whilst back in the surgery waiting for her to exit her temporary “Prison” (Her words, not mine) i was able to do some edits of what I’d seen. A thoroughly enjoyable walk, and a view of the area that on previous walks, has just passed me by.
