Halide has released an update that aims to produce natural, film-like photos on iPhones without relying on artificial intelligence. The update, referred to as Halide Mark III, introduces features such as one-tap color grading and a new user interface, and also utilizes the iPhone 15 Pro's action button as a camera control. Additionally, the update brings macro photography capabilities to all iPhones, but the company is also involved in a lawsuit with a co-founder who was recently hired by Apple.
