I took a photo of my wallet seed with a 35mm camera

What are you worried about..? If the camera is yours and the images are too important then better is to access the wallet again and write down your seed or change it. If you can move funds then make another wallet and transfer everything there. Thats the cheapest option I guess.

Basically some digital cameras have an access to the network and it might be the reason why your funds could be compromised. So for the safety, just do what others are saying, and generate a new seed. The best way is always the traditional which is to write instead of taking pictures of it. That is why hardware wallets advice you to write pass phrase instead of taking photos of it. Just a precaution because no system is safe and everything is hackable except cutting its connection to the network.

Today I have without thinking snapped a photo of my Bitcoin wallet seed with my 35mm camera. I have some important shots on the roll, so I can't just pull it out of the camera (which will destroy not only seed, but the rest of photos as well).

is it colour or B&W film?

you could actually invest in developing it yourself, I used ro develop my own
colour and B&W film but you would have to buy basic equipment.

This all depends on how much the wallet is worth.

or move all coins to a different wallet.

If it is B&W, you could develop it yourself indeed ... you might have found a new hobby   (I wouldn't do it with C41 process color film though).

But seriously, I would not take any risks. Does your camera have the option to double expose? Then you might want to try that for that frame (but analog film has quite some tolerance for over exposure). The safest option indeed is change the seed (if possible) or move the funds to another wallet. Even if your film goes into an automated process, there is usually a manual step afterwards (quality control), so you still run a risk.

You could also ask at the developing lab to be present while the developing
is taking place and dont let them scan/print the negatives until you remove that frame.

if its colour negative it will most likely be machine processed anyway so when it
spits out your roll, wait for it to dry and remove the sensitive frame.

Having an image or picture is really more convenient to do and all info in one capture. However, its somehow risky as it maybe viewed by others. I think its better to copy it manually also. But if having an image maybe preferable to you so might as well secure it properly.

Go to Google images and put in "35mm camera" and see what shows up. These are all old style cameras which haven't been used for the last 20 years pretty much. None of them have any type of wifi connectivity. They use basically those old 35mm film that needs to be manually developed. This was actually a pain because it took a long time to develop, cost alot of money and you couldn't see your photos before they were developed, hence why the digital camera quickly replaced them.

So I don't see how its possible to connect to any outside network, if the owner just develops the film itself. I think you are confused with printers these days. Many printers have a type of memory stored, some have hard-drives, and many have wifi connectivity.  Hence why you shouldn't print any private keys unless they are encrypted in case they have the data stored somewhere.

Some BTC developer joked and said that when he prints his private keys, he destroys the printer just to be safe. I am pretty sure he wasn't kidding.

Take out the habit of not thinking when it comes to your wallet seed it can get you in big trouble, I'm sure you have a copy of your seed and you can still access your wallet, and about your camera, if those are important photos you have to print it yourself and do not let others do it for you unless you transfer the coins to another wallet, when it comes to private seeds you should always be aware of what you are going to do with it.
