How to use ACR to adjust the dispersion, distortion and surrounding brightness

Q: I started to practice using ACR to process raw format files, but I don't know how to do the correction, distortion and ambient brightness. Can these problems be solved in ACR?

A: In the Adobecamera Raw (ACR) program to open you need to modify the photo file, the raw file into a JPEG, you can in the main editor face the lens distortion and surrounding brightness to make corrections.

The raw plug-ins in Photoshop CS contain a series of more powerful raw file tuning tools, including complete lens correction options. The adjustments in this tab are divided into configuration files, colors, and manual 3 parts. In the Configuration file dialog box, a number of manufacturers and various types of lens parameters are given, and ACR automatically corrects the focal length and aperture of the camera.

In the Color tab, there is a feature option called Remove color offset. The slider also supports manual adjustment, using the manual slider, which allows you to make wider adjustments, including correction of horizontal and vertical lines and error correction in perspective.
