How does nikonD7000 take photos with big contrast?

You can increase the contrast by adding Contrast in the built-in settings.

The most important thing is that the shooting content has a great contrast at first, and the light and shade levels are very rich. On sunny days, at noon and cloudy days, it is not easy to take photos with big contrast. Side light, setting sun in the morning and evening, sunny and cloudy, etc. It's easy to shoot.
