Photo post-processing (SLR)

1. Post-processing is unnecessary, especially for people who don't have high requirements for visual effects.

2. Strict senior photographers should post-process the pictures directly from the SLR camera. The reason for this is the following：

2. 1

Experienced photographers are willing to adopt the original information lossless recording storage format (raw). The stored picture file can retain the original image information from the sensor without being processed by the internal processor, and the white balance and gray level of the picture can be greatly adjusted in the later stage to ensure the high success rate of the picture. However, this storage format cannot be directly browsed and used on computers and printing equipment, and must be converted into a common picture format in post-processing.

2.2

SLR cameras have a relatively complete metering-automatic exposure system and automatic white balance function. However, in the case of complex light, some illusions can easily deceive the camera, resulting in unexpected picture effects in the contrast and color of photos. This situation needs to be corrected by manual post-processing.

2.3

Sometimes there will be some mistakes in taking pictures, such as the tilt of the horizon and some chaotic scenes entering the picture. These pictures need to be manually adjusted and cropped later.

2.4

The automatic exposure system design of SLR cameras is generally conservative, so it is necessary to prevent the uncorrectable "dead white" phenomenon caused by local over-brightness. So automatic exposure always tends to be less. This leads to insufficient contrast and gloomy picture. Therefore, the brightness and contrast should be improved appropriately in the later stage, and the processed photos will be more beautiful and pleasing to the eye.

Although the post-processing is complicated, you can't be afraid of trouble if you want to make a good film.
