Using raw files to synthesize HDR good photo Mac version easy to implement

Traditional photographers believe that photography is an art of subtraction: Cutting the complexity of the world and filtering out what you want. Until the birth of HDR, many photographers exclaimed: The original photography can also be added--to the light and color without any escape, on the contrary, all of them collected, will restore the world of this appearance without reservation to the viewer.

This is why HDR can subvert the whole field and create a new era of photography. Please note a keyword: picture information. The richer the information that the picture carries, the better the synthesis of HDR. Therefore, relative to carry picture information less JPG format, commonly known as "digital film" RAW file Synthesis of HDR effect will be better.

This best results require strong support from the computer processing system and HDR software. Believe that a lot of Mac will be in the side of the fun, because the Mac processing speed and effect is extremely excellent, coupled with powerful Chinese image processing software good photos of the advent of this raw and HDR gorgeous collision will let you eye-opening.

Pre-siege exposure shooting process is not here to repeat, this is a group has been photographed a good surround exposure photos, record format for Canon Camera RAW format CR2.

Open a good photo to import the picture, through the left menu bar "picture information" you can see the picture size, size and other basic parameters. Data show that the three raw file size is around 20MB, for general HDR software, such a large volume of file synthesis pressure is very large.

Figure 3 Picture information shows three photos surrounded by exposure pictures are about 20MB in size

However, good photos of the large image real-time processing is very adept, click "HDR", will surround the exposure group selected. Remember to check the "align" and "Go to Ghost" features, these steps are the same as the composite jpg picture. Click "Start" to synthesize.

The raw file itself carries a lot of information, the synthesis speed is slightly slower than the JPG, but based on good photo powerful processing algorithm, the synthesis process is only a few seconds. Some of the HDR software used before the small series is very fast. In this small series chose the "natural Restore" tonal mapping method, in order to restore the most authentic scene.

On this basis, small series or to add some of their own ideas, so that the composition of the effect of oil painting as romantic and gorgeous. Increase the intensity of tonal mapping and appropriate to fill the light, rendering the level of the picture and three-dimensional feeling, increase saturation so that the picture is full of color, more paintings feel.

Oil painting is usually a distant art, so in the "hazy beauty" to build on the need for a vague effect. Choose "blur/Sharpen" in the right-hand menu bar to make this hazy.

Here, you can get a pair of exclusive "aristocratic oil painting". In addition, do not worry that the adjustment process behind will reduce raw information retained, good photo HDR plate adjustment is based on 32-bit, will not damage any quality, so that you get the perfect piece of the best.
