How do I fix dark photos on my iPhone 16 Pro

I recently bought iphone 16 pro, before taking, the pictures are looking good but after taking it is doing some processing and photos are looking horrible. They are very dark. Buying an iphone was my dream. I really frustrated after spending this much money to buy this which is giving garbage photos.

facing the same issue even after updating to 18.4, please let me know if anyone else is also facing the same.
