Methods and principles of photographic post-processing

I often meet friends online and in my life and ask me if your photos look good. Are they PS? The answer to this question is not a simple yes or no answer. Here is a brief introduction to the methods and principles I adopted in the post-processing of digital photography.

First of all, most or every digital photo has undergone some post-processing. Nowadays, digital cameras have a set of internal processing programs, which are called artificial intelligence software in fashionable terms. The most basic is white balance (automatic color correction based on white, and the white surface will show different colors under different lighting conditions. White balance is to correct and rectify the deviation, adjust the color of the picture to make white appear white), reduce mania (the noise of the photo is just like the unclear picture when the TV signal is too weak), and automatically adjust the exposure intensity. These adjustment methods can be preset and adjusted by photographers according to different shooting environments.

General post-processing is to strengthen and readjust these functions.

Generally speaking, I will do the following processing for photos and the principles of processing.

1. Light and shade adjustment. 2. Contrast adjustment. 3. Reduce mania. 4. White balance. 5. Crop (select a part of the whole photo).

In addition to the above basic processing, I will use software to remove some small interference. But the most basic principle is to only reduce and not increase, not to replace flowers. So the photos I sent were post-processed, but not PS. This should be the biggest difference between photography and graphic design. There is no such boundary in the design of picture commercial advertisements, and any combination and grafting can be done.

The following two photos can be used as examples to show the contrast before and after treatment, so as to release cohesion and strength for reference.
