I personally prefer to look at pictures and talk.
Here we will briefly describe the key steps in the gkengine HDR rendering process using graphs and text. If you need to parse it step by step, simply explain the selection of RT creation, release, and texture format. It may take a whole day. If we design the Framework again, the shader's actual processing may not be enough for a few days. So I will not explain the code in detail here.
But here are se

The author's method of making HDR is very good. Process: First enhance the picture of the light and shade contrast, and reduce the saturation of the initial effect, and then use High contrast to keep the filter sharpening to get a good HD effect.

For photography enthusiasts, HDR should be no stranger to me, and even most people think that HDR is a cool effect, but also more popular.
