Quite a spectacle the color of the sky when it rains, it makes me laugh as you say it will be the colors, I hope you can solve it with a good lining you will have to look for a waterproof fabric that allows you to work, a seamstress can give you an idea, or failing that You would have to search the markets for professional linings for the cameras
Cheers!
I used to make all sorts of small devices like this with my own hands from improvised materials.
This is one of my hobbies 🤣 😂😅
Cheers & Thanks!
