Canon Eos 10 test shots

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 As stated the film is over 20 years out of date and there appears to be two problems here.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.

Well, that was most enjoyable!

An enjoyable stroll with a 48 year old camera

The wife told me this morning that she was going out shopping with her sister. Nothing sinister in that, in fact it means two things really. One, I’m going to be a bit lighter in pocket and two, I’m going to have to occupy myself for a while. I have work later this afternoon, so with a couple of hours spare what better time to get out for a walk and to take a 48 year old camera with you that needs testing. This one to be precise: Canon AE1 35mm SLR

I dashed down to take a film out of the fridge, left it sitting for an hour and loaded the camera up, stage one achieved and everything as expected.

Today’s walking companion
Film successfully loaded

Now the film I have been given is one of 8 rolls I have been gifted that are all out of date. This one is a mere 20 years out of date expiring in 2005. This roll of film is older than 21.8% of the Uk population according to the office of national statistics 2024. It’s that old.

Today’s film is a Kodak Gold 200ASA film. There is a general rule of thumb out there that for every ten years the film is out of date you should over expose the film by one stop. So on this film, as it is a further 10 years past that, and if I follow that recommendation then I have to over expose this film by 2 stops. This means in theory that this 200ASA film should be exposed at 50ASA that equates to two stops of overexposure.

I’m not going to do that, I’m going to experiment here. I don’t know how this film has been stored over the years, I don’t even know that it will work at all, it could be fogged or just so deteriorated that it just doesn’t work.

It’s a 36 exposure film so here’s the plan. Exposures 1-12 at std setting of 200ASA. Exposures 13-24 at 100ASA setting and finally the last 12 exposures at 50ASA. Here I cover all bases and should hopefully get a reference roll for the other seven that I have in cold storage at present.

Needless to say I’m not going to be too fussy with what I photograph, scenery, shades, over and under exposure and bright colours, everything that can be used as a reference to check saturation, contrast, grain and film deterioration.

Let’s go.

Off we go

So as stated, I’ve exposed and over exposed equally throughout the roll, so this should cover all bases.

12 exposures of each

Right from the start I have thoroughly enjoyed this little exercise, I spoke to two elder gents who were quite excited at what I was doing and shared their own experiences with traditional film with me, it was lovely, i was even offered an old camera but i politely declined as the wife wouldn’t have been happy with that. I walked 3 miles, I went through some of the less salubrious areas, but these areas had some of the best subject matter.

3 joyous miles of walking

When you are using an old camera, you seem to scan the area more intensely, you see stuff you haven’t seen or noticed before, it’s amazing what you pass and ignore. I think you are less selective with phones and digital media, with film, you are limited so have to be picky.

I bloody loved it. I’d forgot just how good it is to get out there and use good old fashioned equipment.

And that camera behaved just beautifully, everything worked as it should, it is as good as it has ever been, I’m so pleased with how it has behaved so far. See the results here: 20yr old Kodak Gold

I guess the proof is in the pudding as they say. Time to get it processed and to check the results. Needless to say I will feed that back on this blog as soon as it becomes available.

Don’t give up on the past, there is a lot of good tunes played on an old fiddle.

Thanks for passing by, always appreciated.

Expired camera film

What shall I do with all these expired rolls of 35mm film? I know, let’s take some pictures

I’ve recently inherited 8 rolls of life expired 35mm film. In other hands I guess these would just be discarded, and thrown away, however this is me writing, you know, that fool who collects old knackered cameras. That’s me that is.

Well I’m going to use them.

What could possibly go wrong.

8 rolls of film 20 years old

A number of things to be precise, let me enlighten you. As these rolls of films all expired back in 2005 this means they expired 20 years ago, that’s a third of my life span, phew! Film loses its sensitivity over time and we will have to compensate for that when we get to use the film. Colours and dyes fade, and the finished product (if there is one) is likely to look washed out. Add to that the issue of not knowing how the film has been stored over the last 20 years, and this could be the difference between there being an image and just being blank film. If the film has been kept cool, and in a darker environment, there is more of a chance of getting a result than one that has been stored in light and heat. You get the picture….or not.

These rolls are colour negative film all using the C41 chemical development process. And for this type of film and process, the line drawn in the sand says that it’s wise to overexpose the film by 1 stop, for every 10 years (Decade) of expiry. Since the rolls i have are now twenty years out of date, following these guidelines I would be advised to overexpose these films by 2 stops.

Black and white film is more forgiving and might not require adjusting at all, whilst transparency film is totally unforgiving, and personally i wouldn’t touch it with a barge pole.

The higher the ASA setting on the film, means that it requires less light, a lower settings means that more light is required. Therefore, as an example, if these films were originally rated at 400 asa i would now be advised to expose them at 100 asa therefore allowing more light in to expose the deteriorating film accordingly. But remember, when you process the films they must be processed at standard normal development times, if you push or pull the development times you will not achieve the result you require. Develop as normal.

The unknown factor here really is how the film was stored. Chances are that if it was stored in perfect conditions, then we could probably get away with using its original asa setting. But we just don’t know and will just have to suck it and see as they say. We won’t really know how things are going to turnout until we’ve developed the film.

Old film is good for experimental purposes, you don’t really want to trust old film to a photo shoot as you could be wasting time and money. Unless you really want that old washed out retro 70s look.

The film stock I have is listed below:

I have 4 rolls of Kodak Gold 200ASA colour film.

Gold 200 ASA

I also have 4 rolls of Kodak Gold Ultra 400ASA film.

Gold Ultra 400 ASA

All expiry dates are circa 2005, so they are exactly 20 years out of date. I’ve put them all in to cold storage for now but it could well be 20 years too late. Typical for me, always late to the party!

As an aside to these films, I’ve also found a Canon EOS 30 body that I have also been given to get working again, it just so happens to have a partially exposed film inside it. Now this roll I will have to expose as per normal as it has a dx code reader inside, and I can’t override it from what I can tell initially. It will be interesting to see what it returns.

So. When I get around to exposing these films, the 400ASA will be exposed at 100ASA and the 200ASA ones will be exposed at 50ASA. To be honest, I will probably expose half a roll of each at the original setting and then half at the modified setting. It will be good to see the difference, the deterioration and the grain quality. I have a number of old 35mm cameras still to test, so these rolls will be a welcome opportunity to test and experiment, and you don’t often get the opportunity to do this, so I’m going to make the most of it and have some fun.

I’ll let you know how it goes 🤞
