Basic skills of post-photography: the treatment method of changing large films twice in post-photography

1, color temperature: color temperature should be easy to understand. Those too official explanations are too difficult for everyone to understand, so I will briefly explain them here. In fact, simply speaking, the color temperature is mainly used to adjust the color of the picture. If you want to lower the color temperature, the value of k will increase, and if you want to raise the color temperature, the value of k will decrease. Many times we will create a picture atmosphere by adjusting the color temperature. For example, if we want to create a warm atmosphere, we can adjust the color temperature to a lower K value, so that the light in the picture becomes warm and yellowish, thus achieving the desired effect.

2. Highlights and shadows: Why should they be put together? In fact, highlights and shadows are two opposing concepts. Fairies who have been exposed to makeup should be familiar with these two words. "Highlights" and "shadows" in photography have the same meaning as "highlights" and "shadows" in makeup. Roughly speaking, the highlight is the brightest part of the object and the shadow is the darkest part of the object. All the cameras we use are photosensitive elements, but all the photosensitive elements have their own photosensitive range. When the brightness of the light source in the shooting environment exceeds this sensitive range, the photos we take will be overexposed and underexposed, which is equivalent to "highlights and shadows".
