What I normally do whenever I create a new seed is to snap it with another phone because I don't like stories that touches the heart as most times I normally create new seeds for several purposes so am always very careful with it. After snapping it then I write it down in my diary book and check very very carefully before I delete it from the phone though what I normally do most times is to rephrase the whole words in case someone incidentally gets access to my diary book and sees it so that's the safe way I normally do in other to protect my seeds.
Firstly taking a shot of that seed phrase is a bad because it can get exposed to the internet later, yes you might be using the phone offline at that time and later delete it but do you know that the deleted file will be save in your trash and later the deleted image will be exposed to cloud where most phones automatically store your photos?
You're correct on the seed phrases getting exposed to the internet later but it's dependent on the kind of camera with which is being used to capture the seed phrases because not all camera gives the phone access to store files deleted on cloud and if it doesn't involve a camera that stores trashes for some interval of time before it gets exposed to cloud how will it be exposed and besides not all phones automatically stores photos on cloud.
Also rephrasing your seed phrase or even arranging them in any other order can be a security risk because you trust your head to remember how you got them arranged or rephrased and this can be mixed up later as it is bad culture to rely on your head to always remember things like this.
I've done more important things, even passwords by rephrasing them for so many years now and believe me my brain captures exactly how I manipulated everything and I've never gotten any mixed up in the course of me rephrasing some important things that I don't want anyone to understand except me though your advice is welcomed. I know the reason why you assume it to be a bad culture because of if it involves a long time that I might forget how I rearranged everything but trust me I'm very good at remembering how I manipulated anything that's of importance to me even in the long run.

Zaguru12 has corrected this already. It is not good to take the screenshot of your seed phrase. Just use a good wallet like Electrum and make your backup offline. Do not also rephrase your seed phrase, you can just extend it with passphrase. With passphrase, the wallet will generate different keys and addresses. Anyone that will need to access the wallet needs the passphrase. Backup your seed phrase and passphrase differently in different locations. Having like two or three backups each.
Though I don't do screenshots but however, I concur to your advice of running an offline backup on electrum of which I use electrum wallet and extending it with passphrase in other to generate different keys and addresses is also a welcome idea and I must say thank you for the advice.
