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

If you often deal with landscape photos, I believe you will encounter a problem of repairing the picture, is often photographed landscape, will encounter "repair not back" dilemma, this involves a lot of, one is the camera "dynamic range" is not wide enough, the second is that the scene bright, dark contrast is really too big, even the repair map can not be adjusted back, Small series this time to share the advanced landscape map HDR synthesis.

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

We will tell you how to make a high dynamic range Black-and-white image with rich darkened, midtones, and high light details. 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

The gentle romantic works of architecture have become a new trend, how to keep up with the trend and put on the romantic feelings of the buildings that have been photographed?

The HDR Tone command is the new color-adjustment command that is added to the Photoshop CS5 version, which we use to fix too-bright or too-dim images, to produce a highly dynamic range of image effects, and in Photoshop CS5, click icon, select the CS5 new feature option in the expanded menu, and replace it with the appropriate interface. At this point, any click of the menu, in the expanded menu, Photoshop CS5 's new features are shown in

Author: freeknightduzhi Bloom and HDR posts and images are already on the Internet, but it is rare to be clearProgramThe post about the implementation process needs to be explained in a simple way tomorrow, so we will make a supplementary record here. First, HDR is highly dynamic. Note two words: 1: high (High Precision ). 2: Dynamic (Real-time computing during illumination ). Then let's talk about most

Http://blog.csdn.net/a3070173/archive/2008/11/29/3408573.aspx HDR, short for high dynamic rang, is a popular 3D special effect technology. Its basic principle is that although full floating-point tables can be used in computer graphics Color Display, but previously due to hardware restrictions, most of the texture formats loaded from the outside can only be expressed in one byte for each color component, that is, 0-255, When this low-range color

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
