temporarily exceed 1.0, and then transform it between 0.0 and 1.0, so that no details will be lost.Although the display can only display colors ranging from 0.0 to 1.0, the lighting calculation does not have this range limit. We can use high dynamic range (HDR) to save a value with a fragment color greater than 1.0. The HDR color range values simulate the brightest rays from the sun to the darkest shadows,
Alignment correction of a multiple exposure picture group
In the process of photographing the HDR multiple exposure picture Group, it is best to use a tripod to ensure that the multiple exposure picture group that is photographed is fully one by one corresponding to each pixel coordinate to obtain a clear HDR image. But the process of using a tripod is cumbersome, and in most cases we prefer to shoot multi

1. What is HDR?
HDR is short for High-dynamic range. In real-time rendering, it is called high-Dynamic Range illumination rendering. It is an image ing technology that expresses the brightness range beyond the display's performance.
2 Why HDR?
Normally, the display can display pixels with RGB components between (0,255), that is, the backbuffer format that we fina
know what is high contrast, which is low contrast, of course, here is relative to the height.
Generally speaking, my experience is that the picture is gray, contrast is low, the screen Black-and-white contrast is obvious or particularly bright, contrast high.
Saturation contrast
Saturation refers to the brightness of the color, in general, the higher the saturation, the more colorful color, black and white gray three-color performance is weaker, and vice versa. Low saturation, bl

An excellent high dynamic range (HDR) image Works can make people stop and enjoy the pace of the hurry. This can be done using the merge to HDR commands in Photoshop. We use a number of different exposures through the digital darkroom, and the resulting photos contain ri
What is HDR
The HDR full name is a high dynamic range. This is a simple term for an HDR image that uses several different exposures and then uses the software to combine them into a single picture.
The advantage is that eventually you can get a picture of the detail in either the shaded part or the High light section. In normal photography, perhaps you can only
HDR simulates the real-world dynamic range that the human eye can see, and many photographers say that when you first use HDR, you are very unaccustomed to the effects of the resultant image, regardless of which hue map you choose, always feel a bit fake.
In fact, this kind of false feeling is normal, the popularization and popularization of digital machines in the past decade has made people fully adapt t

HDR stands for high dynamic range, which is a high dynamic range, such as a high dynamic range image (hdri) or a high dynamic range rendering (hdrr ). The dynamic range refers to the relative ratio of the highest signal to the lowest value. Currently, the 16-bit integer format uses the color value from "0" (black) to "1" (white), but the so-called "over range" value is not allowed, for example, the color of the highlights on a metal surface that is wh
In the game engine rendering pipeline, our range of values for R, G, b channel color information is usually set between [0,1] (or [0,255]). Of these, 0 represents no brightness, and 1 represents the maximum brightness that the display can display. Although it is straightforward to understand, it does not reflect the real-world brightness of the situation. In a real-world lighting environment, light intensity can sometimes exceed the maximum brightness displayed by the display. Moreover, the huma

The so-called HDR means a high dynamic range. In normal display and bitmap, each channel is 8-bit, that is, the RGB component range is 0-255, which indicates that the actual color is obviously far from enough. In reality, the dynamic range of images is much larger, so how can we maintain a larger dynamic range in the existing display devices as much as possible, in addition, making it more in line with human habits has become a hot topic in graphics r
