How to adjust photo brightness on Nick d3200?

This cannot be explained clearly in one sentence, but it has nothing to do with the camera. Post-production is a professional skill.

To put it simply, adjusting the brightness/contrast, as well as the level tools and curves can meet the requirements, but this is not enough, because when you change the picture, it will affect other attributes, such as saturation, hue, and the color of the picture. Color structure will be affected.

As your understanding of retouching continues to improve, your pursuit will also improve. To achieve professional-level retouching, you don’t necessarily need to take any courses or buy books. There are plenty of online learning materials, but The most important thing is to understand the basic knowledge of color, understand color balance, understand the structure of the picture and the ideas you need to express. There are no fixed parameters and it requires years of post-production training. It is recommended to use PS2019 or above version because of the built-in ACR plug-in. Generally speaking, you can basically get it done by using this tool proficiently, because this tool contains most of the basic tools of PS, but again, you need to continue to learn about color and overall. The grasp of the picture.

In order to take photos with a large light ratio, the photos are underexposed by several steps according to the situation. The purpose is to retain the highlight details. Brightening after underexposure is a necessary skill. Forget about HDR.

The following is a case of underexposure and brightening. The original image (RAW) was underexposed in three stops. In order to retain the details of the sky highlights and leaves, it was brightened in the later stage.

The first is to increase the exposure. It is worth mentioning here that increasing the exposure in the later stage is equivalent to the camera increasing the aperture or lowering the shutter speed or raising the ISO. In addition to being limited by the color scale overflow, it is not affected by the shutter and aperture. ISO limit, so when you have the skills in post-production, if the light is insufficient during early shooting, you do not need to lower the shutter speed or increase the aperture or increase the ISO, because these three items have side effects. A slow shutter speed is easy to shake, and a large aperture is better, but The depth of field when shooting landscapes is not enough, and color noise is prone to appear in dark areas at high ISO. These problems are difficult to deal with later.

Then control the highlight white and shadow black so that the color levels are evenly distributed between 0-255, and try not to hit the wall on the left and right sides of the histogram. Then observe the sharpness, color and saturation of the picture to adjust the relevant parameters. Fine-tune it to achieve the best visual requirements.
