How to take a warm style photo with a mobile phone?

First, choose content with warm style. Fragments of daily life or small objects can give people a very intimate feeling. Then, when shooting, we usually use a closer perspective, because a closer perspective will be closer to the warm style. The famous photographer robert capa once said, "If your photos are not good enough, you are not close enough." I think as long as you are close enough, you will pay enough attention to it. Finally, try to use mild tones in the rendering of photos, so that photos will make people look warm.
