Is it actually okay to use a card camera to learn photography?

Actually, you can. It depends on how you view photography. Card cameras can train your photography awareness. Of course, technology is also very important. I have seen some foreign classic works that did not use difficult photography techniques but showed considerable photography awareness. I think if you can make good use of the card machine and you become interested, you will naturally want to improve your skills and burn photographic equipment.

I hope you persist
