I hope that you found this tutorial useful. Here is the result of a quick Lens correction to a Photography that I shot of Union Station in Chicago. Here are the settings inside Lens correction, notice I didn’t use every options, just the ones I needed and I also used much more subtle settings here. Note that is was an extreme example to show you the workflow and features in the Lens Correction tool. Drag on one side to fix the skewed problem.

This can be fixed by choosing Ctrl/Cmd+T for free transform mode Sometimes when you have been doing heavy lens correction like we have here (or even with the upright adjustment in Camera Raw) you can end up with a skewed effect, almost as if one side has been pushed up and the other side pushed down. As you can see this really is a great tool for fixing distorted images. To finish off the effect, crop the image to suit your needs. The Vertical Perspective has been readjusted to compensate. Once the tool is selected you can drag in the image, although I find that the sliders give you more control.Īfter adjusting the distortion, you may need to go back and again tweak the perspective. This also works by choosing the Remove Distortion tool, which is the topmost tool icon on the left of the Lens Correction window. Move the Remove Distortion slider to the left to ‘bulge out’ and move to the right to ‘pinch in’. You can also change the Angle to counter a diagonal distortionĪdjust the scale slider to see more of the image if necessary What’s really happening is that we’re making one side narrower than the other to combat perspective problems. The image suffers from keystoning – it’s narrower at the bottom than the top – so we’ll adjust the Vertical Perspective to make the top and bottom the same width.Īdjusting the Horizontal perspective appears to rotate the image through 3D space. It’s impossible to fix all the other angles if the image is not straight first.Ĭhoose the straighten tool for the left side of the dialogue boxĬlick-&-drag across the image to define the new horizon, Try to follow a horizontal line in the image if there is one. The first job is to straighten the image. Notice the grid that assists us in lining things up, you can also change the size of the grid with the slider to make it match your photo Open an affected image and choose Filter>Lens Correction and click on the custom tab To demonstrate, let’s take an image that suffers from many problems, and correct it. Not only can it remedy the bulging created by a wide-angle lens, and the weird distortion created by taking a photo too close to subject – such as the bulging nose of a friend – but it can also straighten images taken at angles and make them appear as if they were shot straight on. The Lens correction filter is truly amazing, being able to repair all kinds of distortions.
#Camera lens distortion grid card manual
Ok, onto the Manual Lens Correction on a very difficult image
Simply turn on the Geometric Distortion open and the Fish eye is removed because the Filter has access to the metadata of the photograph and matches it with presets from the Adobe Lens Correction database of cameras and lenses. Here I have opened an image that was shot with a DJI Phantom 2 Vision Quadcopter camera. We will touch on the Auto settings here, but we will concentrate on the manual settings that will work with any image. There are automated things like upright in lightroom tutorial here) | Upright in Photoshop Tutorial here and lens profile corrections (more corrections here on this video) and then there are things that you can do manually.
There are a lot of different things that can be done with the Lens Correction Filter in Photoshop.
