LENS correction Function! One minute to easily eliminate lens distortion

Many friends have come across the trouble caused by lens distortion, especially when using a cheap wide-angle lens, troubles often rise to extreme distress. There is no doubt that Adobe engineers are experiencing this distress, so in the latest version of Photoshop CS2 We are pleasantly surprised to see the lens correction filter (Lens correction filter).

Next, let's take a closer look at this filter. Open a photo, this is the construction scene that uses 20D to match 10-22mm lens to shoot. This picture is obviously distorted because of the camera's visual angle and the limited equipment.

We clicked on the filter in the menu bar--distorted--lens correction. If you find that lens correction is not active, then you look at the image mode of your photo, and it seems that only RGB photos can use this filter.

Let's take a look at the lens correction window, the right window is the ribbon, and the left window is observation area.

At first glance this interface is very complex, the actual operation is very simple. All the buttons are graphically labeled, just try it out and you'll be able to master it. Let's adjust the trapezoidal distortion first.

In observation area, we can enlarge the image for careful observation, and can also display the grid for reference.

Next, we adjust the barrel shape of the wide-angle lens and the surrounding black halo. For barrel deformations, we simply drag the first slider (remove the deformed remove distortion) to the right.

For the surrounding black Halo, we only have to drag the second to third slider to move. All the adjustments will be displayed in real time in observation area, so it's perfectly easy to do so.

After just a minute of adjustment, the photos can be said to have been a new facelift!

However, because the lens correction filter operation will affect the quality of the photos, so need sharpening.

Finally, we need to emphasize that later is not omnipotent, if we can solve or reduce the impact of lens distortion in the early stage, then do not stay until later to resolve.
