The Transform Panel in Adobe ® Lightroom
As you can see in the next figure, the Transform Panel has two sections. The Upright section with six buttons and the Transform section with seven sliders and a checkbox to constrain the crop.
The Update tool in the upper right corner and the Constrain Crop checkbox in the bottom work independently from the section in which you find them located.
It is possible to use the sliders of the Transform section and the buttons of the Upright section in combination. However, to do so, you have to first use the Upright section and then make finer adjustments in the Transform section. If you use the Transform sections sliders first and then a button from the Upright section, your sliders will be moved back into their initial position.
What kind of tools does the Transform Panel offer?
This Panel gives you some helpful tools to counteract lens distortion.
Wait; what? Did we not just through the last two articles cover lens distortion? Yes, we did. However, the Lens Corrections Panel might not always be capable of helping you to remove all the lens distortion from your image. Finetuning the distortion removal of the Lens Corrections Panel is when the Transform Panel comes into the game of post-processing.
Since both the Lens Corrections Panel and the Transform Panel correct lens distortion, it is advisable to use the Lens Corrections Panel’s distortion removal before you move on to the Transform Panel.
Should you, for whatever reason, have to change settings in the Lens Corrections Panel after you have applied settings in the Transform Panel, you need to click on the Update tool to trigger a re-calculation. This Update tool is only active if you have used Lens Corrections after you made any changes to the Transform settings.
The buttons of the Upright section in the Transform Panel
Double-clicking on the word Upright activates the Off-Button, which we have a look at next.
Obviously, this turns all automatic or semi-automatic transformations, that you might have applied in the Transform Panels Upright section, off. However, the adjustments that you made in the Transform section are not affected.
Corrects both vertical and horizontal distortions.
With the help of up to four guides, two horizontal and two vertical, it calculates a perspective correction for your image. Notice that, when you click on the Guided Button, you are automatically activating the cross-hair tool in the top left corner of the Transform Panel and vice versa.
This Tool works best if you have clear horizontal and or vertical lines in your image. Since the most significant distortion happens to off-center areas, you should use guided lines on off-center objects as well. You will get the best results if you apply long guides far away from each other. So, for example, one horizontal in the top third, one in the bottom and the verticals in the left and right thirds, will help you achieve a better result than having both horizontals in the top third and both verticals to the right of your photo.
For the skyline of Seattle in the next figure, I chose one vertical on the right side of the dark blue skyscraper to the left, the other one down the left side of the far-right brown building. For the horizontal guiding line, I chose the roof of the second brown building from the right, which remains in the image. Now ideally, I should select a second vertical line; however, after multiple attempts, I found that all left me with an egg-shaped Farris-wheel. So the good old proverb less is more works here too.
The original, uncorrected version looks like this:
Corrects horizontal distortions. It does the same as the Angle tool in the Crop and Straighten Tool, just not necessarily quite as good.
Corrects vertical distortions and can rotate your photo a bit.
This button offers a combination of Horizontal (Level), Vertical, and Auto distortion correction. However, it tends to try to do too much. I used the Full button to try to fix the skyline of Seattle in the following figure. And as you can see, the Ferris wheel now is more eggshaped than round.
The Sliders of the Transform section
As with all sliders that we have examined so far, if you double-click on the name of a slider Adobe ® Lightroom moves it back into its initial position.
If you double-click on the word Transform all sliders of the Transform section will be moved back into their initial position.
Using a button of the Upright section after you have moved one or more of the Transform sliders out of their initial position, will move them back. However, if you want to combine the slider’s settings with the Upright sections buttons, you can hold the <Alt>-Key (Windows, <Option>-Key for Mac) to add the effect of your chosen Upright button to your slider settings from the Transform section.
Corrects vertical distortions. Moving the slider to the right tilts your photo backward, moving it to the left tilts your image forward.
Additionally, using the Vertical slider, can stretch your photo a little bit.
Corrects horizontal distortions. Moving it to the right turns your photo to the right, moving it to the left turns your photo to the left.
Rotates your photo up to 10˚ to the left or right. The rotation direction depends on the direction in which you are moving the slider.
Shrinks or stretches your photo along the horizontal perimeter.
Enlarges or scales down the size of your photo. This slider can be useful if removing the distortion from your image also cut off some crucial parts.
Moves your image to the left or right along the horizontal (X) axis.
Moves your photo to the top or bottom along the vertical (Y) axis.
