RAW format Photo processing techniques

Camera Raw Basic Use method

Taking photos in RAW format is a big advantage for digital SLR cameras. Raw format contains a large number of image information, compared to the JPEG format adjustment is more powerful, while the resulting loss of the screen is correspondingly lower, we will introduce Photoshop camera Raw plug-ins. Raw format adjustment plug-ins in Photoshop software are updated frequently, and you cannot open RAW format photos If you are not using the latest Photoshop software version. Update files for the Camera Raw plugin can be downloaded on Adobe's official website. In Photoshop, perform the file-open command, and in the Open dialog box that pops up, select the RAW format photo you want to adjust.

Step 1

Figure 1

Photoshop starts the camera Raw plug-in automatically (the plug-in can be viewed as a feature software that is mounted in Photoshop). At this point in the interface, the left is to adjust the raw format of the photo, the top right is the picture of the histogram, the lower right for adjustment options. Now position the mouse pointer over the triangle icon in the upper-left corner of the histogram and click to activate the Shadow Trim warning feature, where the missing detail in the photo is displayed in blue.

Step 2

Using the same method, position the mouse pointer over the high-light trim warning triangle icon on the upper-right side of the vertical graph. When clicked, all parts of the photo that have lost detail due to light are displayed in red. These warning features can be used as a reference when working with photos, and can be seen from here that the plugin is specifically designed for fine processing of photos.

Step 3

Using the same method, position the mouse pointer over the high-light trim warning triangle icon on the upper-right side of the vertical graph. When clicked, all parts of the photo that have lost detail due to light are displayed in red. These warning features can be used as a reference when working with photos, and can be seen from here that the plugin is specifically designed for fine processing of photos.

Step 4

Because the camera raw plugin has a limited display of photos, if you need to observe and adjust the details of the photos, you can use the Magnifier feature in the camera raw top bar. Click the magnifying glass icon, and then click in the photo to enlarge and view the photo, and if you hold down the ALT key and click in the photo, you can zoom out on the photo.

Step 5

Figure 5

At the top left of the camera Raw interface, above the store image button, click the Triangle button to activate the Select Zoom Level pull-down menu. Select the zoom ratio to zoom in on the photo to make the photo detail visible. The more practical is the "100% proportional display" and "Fit view size" two items.

Step 6

Figure 6

Photos in 100% proportional mode display, the details will be clear, can be used to see if the local exposure is excessive or insufficient, but also can view the clarity and level of the shooting subject. At the same time, you can also match the camera Raw above the "hand tool" in the toolbar, hold down the left mouse button on the photo drag, change the browsing location.

Quickly improve photo quality

In camera raw, the most common is the "basic" adjustment option, which mainly includes the color temperature of the photo processing, exposure processing, contrast processing and saturation processing, and other important functions. By using these features, you can make a raw photo of the new face, the following specific description.

Step 1

Figure 1

Flowers are photography enthusiasts most often photographed subject matter, often at home can get the picture vivid color beautiful pictures. In the example, when the photograph is taken, because the flowers are in the backlight position, the use of the digital SLR camera in the automatic metering mode shooting, the shot into the light than the flowers reflected in the lens of light, so the photo produced a problem of exposure, the screen looks bleak, exposure, contrast and saturation are to be improved.

Step 2

Import photos into CA m e r aw, locate the Exposure adjustment slider, position the mouse pointer over the slider, move the slider to the right by holding down the left mouse button, and release the mouse when the value is displayed to "+0.75". Through this step, we increase the exposure for the photo, making the picture brighter, while the flowers are becoming more colorful. Through the camera raw interface in the upper right of the histogram can be seen, the adjustment before the color block on the left, adjusted histogram is evenly extended expansion.

Step 3

Figure 3

The previous step increases the exposure value of the photo, so the screen looks brighter than before the adjustment. But because of the effect of the whole picture application, the dark part of the picture is also promoted at the same time, the photos appear to be relatively low contrast, weak contrast. At this point you can find the "black" adjustment slider, according to the screen display will be the number set in "20", so that the dark color of the picture more dense, increase the contrast, so that the picture looks more calm.

Step 4

Figure 4

After the "black" adjustment, the picture looks closer to the visual image of the camera, but the color is not strong enough. Here, locate the Contrast slider and set the contrast to "+30." At this time because of the increase in contrast, the histogram of the picture is more compact, the picture contrast nearly one step, the color is more gorgeous, backlight light point brighter, the color of the dark part of the leaf is thicker.

Step 5

Figure 5

To make the picture more colorful, you can use the Saturation slider in the basic adjustment bar in camera raw. If you've ever used Photoshop's hue/saturation feature, you'll find that the adjustment will cause the screen to appear in a spot. This is because Photoshop is not only a photo-processing software, but also has a graphic design function, and camera raw in the adjustment will take into account the problem of photo quality loss. Here we slide the saturation slider to "+20" to make the picture more vivid and lively.

Step 6

Figure 6

After a step of adjustment, the flowers and the color of the green leaves have been significantly improved, but because cameraraw to the image quality protection, so the quality of the potential for further improvement. Because the saturation adjustment function is for the whole picture, so if all the colors are too saturated to cause all the details to be connected to a single and cannot be resolved, then you can use the "detail saturation" function to continue to adjust, it can protect the saturated color under the premise of continuing to beautify the photo color.
