Join Richard Harrington for an in-depth discussion in this video Removing distortion with manual controls, part of Editing GoPro HERO Photos and Videos with Lightroom and Photoshop.
- If the Auto controls and Photoshop or Lightroom's ability to guess doesn't work for you, you can always take complete precision by adjusting each slider individually. Now you saw me twiddle with this a bit but let's build it up from scratch. I've got a shot here that's pretty good. Let's go into the Develop module and you see that the Lens Correction has already been applied for a basic adjustment. I'm gonna turn that off instead and just go with purely manual controls. You'll note that the Distortion slider is quite useful for doing a barrel type distortion.
And I'm just going until the horizon looks straight. Not too bad there. Remember, you can zoom in if you wanna check with closer detail. Once that's done it's not uncommon to have to do a little bit of Rotation. There we go. That's looking fairly straight. Additionally, you can tilt the image side to side to compensate if needed.
Same with a vertical tilt which tilts from top to bottom. Which can be useful if you have perspective problems. Once you've got that done, just zoom out so you see the whole image and you're likely going to want to adjust the Scale. If the image has become distorted Aspect can stretch the image to the left or taller, which can be useful if you'd like to Distort it until it fills the frame or emphasize different details.
Once that's set take advantage of Vignetting to darken the frame or lighten the edges. This is not meant to be stylized though. This is really to compensate for any darkness or brightness caused by the lens itself. That's looking pretty good. Once that's all done then you can take advantage of any other controls in Lightroom. Letting you easily White Balance a shot, refine it's Exposure, tweak the Shadows and the Highlights, go after Clarity and Color and, of course, work with any of the other adjustments that you're used to.
Such as Curves. And we'll just refine this here slightly by rolling the Oranges and Reds just a little bit. So all of those Controls are right there and it all comes down with manually tweaking the lens. Giving you those full options available. Now, inside of Photoshop the controls are exactly the same. You've already seen these, in fact. My normal workflow is this. I will take advantage of, first, the Lens Profile. Once that's done I'll take a look at Tools like Upright or the Adaptive Wide Angle command to help me.
If things still don't work then I'll dial in manual adjustments, always using the horizon line as guidance first. Once that's set you can tackle strong vertical or horizontal lines to really feel that you've got the perspective right. But at this point, you're really doing it by eye so take your time and look at what each adjustment does.
Author Rich Harrington starts with the basics: importing and organizing photos, correcting distortion, adjusting color and exposure, and getting ready for print. He then moves on to working with video: developing color and exposure with adjustment layers and presets, and then rendering out the adjustments for editing in another application. He wraps things up with a short, fun tutorial on assembling a time-lapse sequence.
