Photo Processing High

Post processing of digital photos can be divided into two phases. The first stage, can accurately restore digital photos to look at the human eye can see; the second phase, to some special processing on the photos to increase the effects, synthesis and so on. If you want to learn digital photography post-processing, we must start from the first stage. As the Raw format to maximize the retention of electronic film a photo of the original information, so the most suitable for post-processing and high-fidelity restore human vision.

This paper to discuss with everyone dealing with the Photoshop Raw format photos of some of the most basic methods and techniques.

One, set up the digital darkroom with ACR

Raw photo software can handle a lot, but I believe that Adobe CameraRaw (referred to as ACR) best suited to beginners, the software interface shown in Figure 1.

ACR is that it is a plug-in, PhotoshopCS3 above all own, and seamless integration, and Photoshop. Simple interface and reasonable function division makes more easy to use ACR, in meeting the professional players on the high quality picture processing requirements and also for entry-level players on the pictures is simple, fast requirements.

II, multi-format output photo Raw format e-film deal, we will generally output as JPG, TIFF and other formats for easy viewing and printing. In the ACR, the press can do the following.

Start Photoshop, drag a Raw File Icon to the window, ACR will automatically run and open the Raw files, the interface as before Figure 1. Click the bottom left of the “memory image” button, will pop up a dialog box. Shown in Figure 2, in the bottom left of the “format” option, we can set a variety of output image format.

3, Raw picture film cleaning combat

Beautiful scenery is like shooting all the content, the general picture according to the process flow is:

adjust the white balance correction exposure, contrast, shadow, light Correction and adjustment of high color image sharpening and noise reduction output cut and other modified Images

Here we pass to describe a typical case of washing with ACR Raw basic techniques of film. Figure 3 is a display of Tibetan Shangri-La residential landscape of Raw electronic film.

This photo following major issues: White balance does not reflect the characteristics of light at dusk

less exposure, less contrast color flat lack of sharpness, soft

Not worry about these issues, ACR can be easily resolved, come together.

1. Lossless quality white balance correction

Order to restore the light conditions when shooting at dusk, we first carried out on the image of the white balance correction. ACR software to the top position in the order of the slider is the White Balance correction tool (Figure 4), which provides two preset white balance adjustment mode slider, and a drop-down menu, color temperature and color provide precise control of white balance possible, and this adjustment is non-destructive image quality.

We select the cloudy white balance modes to enhance images of warm, reflecting sunset colors.

Experience: First, we can recall the actual circumstances, such as sunlight, cloudy, incandescent, etc., directly under the white balance option is selected the corresponding option, if the picture is not restored to the human visual system at the time, fine-tune the color temperature slider can be accurately restored.

2. Exposure Correction Complete the white balance correction, the next improvement is the photo exposure and contrast. White Balance command below is followed by the exposure, recovery, fill light, black, brightness, contrast and other adjustments command.

Tips: How to determine due to exposure and overexposure

The top in the functional area, we can see a chart like many small hills, this is the histogram, it can accurately display the photo exposure situation. When a large number of crowded peaks to the far left or far right and the formation of truncated faces, on that picture there is less exposure or overexposure problems, while the corresponding sides of the chart at the top of the small triangle will be lit.
