"Hide" feature in Camera raw

Panorama Synthetic Distortion control is more excellent than PS

Camera Raw is the most familiar with the raw file processing tools, with recent updates, Camera raw function more and more rich, in addition to the original regulation of content, Camera raw adjustment independence is also more and more strong, some of the original use of the function of PS is now in Camera Raw is also reflected in. The following author for everyone to bring five camera raw in recent generations of the update of the small function, I hope it can help you to repair the map.

　• Panorama synthetic Distortion control is more excellent than PS

First, we start with the two newest updated image processing merging features in Camera raw. Panorama synthesis and HDR synthesis are features that camera raw after 9.0, and these two features are independent of PS photo synthesis and HDR synthesis, which make it possible to synthesize panoramic or HDR images from raw files, and most importantly, the synthesized picture is DNG format and is a generic raw file, and can still use camera raw for lossless adjustments later on.

Panorama synthesis and HDR synthesis are two very useful synthesis functions (this article is recommended to click to view larger image)

For the panorama synthesis, we have before a certain introduction, the following we look at the specific application of this function. The use of panoramic synthesis requires early preparation, in the early stage we need to follow the standard steps to take, that is, the use of manual exposure and manual focus, and then the horizontal patch. After the film is finished, we will import all of the raw files into camera raw, and then perform the patch operation.

We can see that the computer will first generate a small preview of the screen, allowing the user to decide whether to continue the patch work. Then we choose the Dng file to save the address, the computer will automatically carry out the work. It is noteworthy that the use of camera raw patch, the need for greater memory and cache disk, so you should carefully select the number of the original file. The completion of this step, is the process of waiting, in the Camera raw down-chip speed in fact faster than PS, but need a higher configuration.

Next, the preview file is generated first

After successful, there are very important steps to remove the distortion. The new version of Camera Raw provides a good distortion correction, and has automatic clipping function, which is more simple than the PS in the operation of the chip. More importantly, the use of camera raw connectors, the computer will automatically recognize the camera lens correction, so the distortion control is better.

After the success of the patch, you will get the raw file, you can continue to use camera raw for other adjustments

From the practical application, the Camera raw patch effect is better than the PS itself, and as long as the configuration to meet the demand, in fact, the raw files will be faster, and the distortion will be smaller. So for users who often synthesize panoramic photos, it is more recommended to use this new feature.

　· HDR synthesis based on RAW file screen cleaner

The next feature is HDR synthesis, and we know that PS has its own HDR synthesis feature that can automatically synthesize multiple photos into an HDR image, but this method generally has the edge of high light apparent, the image distortion serious problem. The new version of Camera Raw also has HDR synthesis based on raw files, and the synthesized format is the DNG generic raw format.

The use of HDR is the same as the Panorama synthesis.

In use, as with the panorama we need to first import all the photos into camera raw, and then use the HDR synthesis function, we can combine multiple photos into an HDR raw file, we can adjust it properly. Note: The use of raw files for the patch, we must have surrounded by the exposure of several groups of photos, but not a single raw file to modify the exposure of the picture.

HDR speed is much faster than panorama synthesis speed

However, as you can see, the HDR in Camera Raw is not a fully independent composite image, and a part of the HDR effect is derived from the synthesized file, and many of the adjustments come from the adjustment of its own parameters. Therefore, using this method to synthesize HDR, the adjusted file is not the special effects we see in PS, we need to add some exposure adjustment content to appear better visual effect. Of course, in the synthesis of the computer will use automatic mode to automatically balance the light ratio, we can also modify the parameters.

Can be seen, in fact camera raw HDR can be understood as reference adjustment

So, compared to the panorama synthesis, HDR synthesis is not strong, sometimes with a single picture of the adjustment effect of the gradient filter is not obvious, but this is really a lot of information to integrate a new image of brightness. Because the raw file itself has a high adjustment amplitude, so for the general environment, the actual application value of this synthesis is very high. Using raw file connectors, the biggest significance is that the photo is less noisy, and does not appear a large number of high light edge, this is the PS in the HDR effect can not do.

　• Histogram control Another exposure adjustment mode

In the recent camera raw, there is a small hidden function, we can directly drag the histogram, you can complete the photo exposure control. This is a boon for friends who are unfamiliar with the dimming shadow adjustment.

In general, we would prefer the histogram distribution to be near the middle (but not absolutely, we need to determine according to the actual photo)

When it comes to adjusting the histogram, let's first say what histograms are the most expressive. Histogram provides the image of the brightness information distribution, the left side of the histogram represents brightness of 0, black and white to see is the highest brightness on the right, black and white to see is white. Therefore, in order to make the photos more consistent with the aesthetic feelings of human eyes, we should try to make the histogram from left to right covered the entire histogram area, and "peak" in the middle of the histogram, into a mountain-like.

For those who are unfamiliar with the adjustment below, Adobe now allows users to adjust the histogram directly

Therefore, the direct control of the histogram after the function, Caemra raw directly to the histogram into 5 regions, we select a region, direct drag can change the exposure, so as to better control the overall image exposure. In fact, this adjustment corresponds to such adjustments as exposure, highlights, shadows, and so on, but unlike data adjustments, this adjustment is done automatically by the software. When we are wavering in the parameters of the basic adjustment, try to adjust the histogram directly sometimes has a good effect.
