The Develop module contains tools and controls for cropping and straightening photos. Lightroom Classic crop and straighten controls work by first setting a crop boundary, and then moving and rotating the image in relation to the crop boundary. Or, you can use more traditional crop and straighten tools and drag directly in the photo.

As you adjust the crop overlay or move the image, Lightroom Classic displays a grid of thirds within the outline to help you compose your final image. As you rotate an image, a finer grid appears to help you align to the straight lines in the image.

Select the Crop Overlay tool inthe tool strip, or press R.
An outline with adjustment handles appears around the photo.
Drag in the photo with the Crop Frame pointer or draga crop handle to set the crop boundary. Corner handles adjust bothimage width and height.
Note:
After you drag a crop handle, select the Crop Frametool to use it.
Reposition the photo by dragging the photo within thecrop frame using the Hand tool.
(Optional) Select Constrain To Warp to keep the cropbounding box within the image area when lens corrections have beenapplied. Constrain To Warp prevents the photo from becoming distorted.
Click the Crop Overlay tool or press Enter (Windows)or Return (Mac OS) when you’re finished cropping and straightening.

Note:

Press O to cycle through grid overlaysin the crop area. To display the grid only when cropping, chooseTools > Tool Overlay > Auto Show. To turnoff the grid, choose Tools > Tool Overlay >Never Show.

The padlock icon in the tool drawer indicates and controlswhether the crop controls are constrained.

Choose an aspect ratio from the Aspect pop-up menu nextto the padlock. Choose Original to specify the photo’s originalaspect ratio. Choose Enter Custom to specify an aspect ratio thatis not listed.

Note:

Press Shift+A to select the Crop Overlaytool with the last-used aspect ratio.

Lightroom Classic stores up to five custom crop ratios. If you create more than that, the older ones drop off the list.

Drag a crop handle to set the crop outline or drag withthe Crop Frame tool .

Note:

Press Shift as you drag a crop handle totemporarily constrain to the current aspect ratio.

Press X to change the orientation from landscapeto portrait or portrait to landscape.

Select the Crop Overlay tool inthe tool strip, and do one of the following:

• Rotate the photo using the Angle slider.

• Rotate the photo by moving the pointer outside acorner crop handle to display the Rotate icon , andthen drag to rotate the image. The axis of rotation is the centerof the crop rectangle.

• Select the Angle tool , andthen drag in the photo along a line that you want to be horizontalor vertical.

Note:

Holding down Alt (Windows) or Option(Mac OS) with the Straighten tool selected displays a gridthat helps you straighten the photo.

• To rotate a photo in 90-degreeincrements, choose Photo > Rotate Left or Rotate Right.To rotate a photo to less than 90 degrees, see Straightena photo. The photo rotates in a clockwise or counterclockwisedirection around its center point.
• To flip a photo horizontally from front to back so thatyou’re looking at a mirror image, choose Photo > FlipHorizontal. Objects that appeared on the left side appear on theright side, and vice versa. Text in the photo will show in reversed mirrorimage.
• To flip a photo vertically from front to back so thatyou’re looking at a mirror image upside down, choose Photo >Flip Vertical.

You sharpen photos at two stages in the Lightroom Classic workflow: as you view and edit photos, and when you print or export them. Sharpening is part of the camera default that Lightroom Classic automatically applies to your photos.

When Lightroom Classic exports, prints, or rasterizes a photo for editing in an external editor, the sharpen setting for the image is applied to the rendered file.

In the Develop module, zoom in on the photo toat least 100%.

Drag in the Navigator panel to see an area of the photothat highlights the effect of the sharpening adjustment.

In the Detail panel, adjust any of the following Sharpeningsettings:

Adjusts edge definition. Increase the Amount value toincrease sharpening. A value of zero (0) turns off sharpening. Ingeneral, set Amount to a lower value for cleaner images. The adjustmentlocates pixels that differ from surrounding pixels based on thethreshold you specify and increases the pixels’ contrast by theamount you specify.

Adjusts the size of the details that sharpening is appliedto. Photos with very fine details may need a lower radius setting.Photos with larger details may be able to use a larger radius. Usingtoo large a radius generally results in unnatural-looking results.

Adjusts how much high-frequency information is sharpenedin the image and how much the sharpening process emphasizes edges.Lower settings primarily sharpen edges to remove blurring. Highervalues are useful for making the textures in the image more pronounced.

Controls an edge mask. With a setting of zero (0), everythingin the image receives the same amount of sharpening. With a settingof 100, sharpening is mostly restricted to those areas near thestrongest edges.

Press Alt (Windows) or Option (Mac OS) whiledragging a slider to see the areas being affected (white) versusthe areas masked out (black).

Note:

To turn offsharpening, set the Amount slider to zero (0) or click the Detailpanel On/Off icon .

Image noise is extraneous visible artifacts that degrade image quality. Image noise includes luminance (grayscale) noise, which makes an image look grainy, and chroma (color) noise, which is usually visible as colored artifacts in the image. Photos taken with high ISO speeds or less-sophisticated digital cameras can have noticeable noise.

(Optional) Zoom in on the photo to at least 1:1to better see image noise and the effects of the sliders.

Drag the 1:1 image preview in the Detail panel of theDevelop module to see the area of the photo that looks grainy ordisplays colored artifacts.

In the Noise Reduction area of the Detail panel, adjustany of the sliders. The first three sliders affect luminance noise.The last two sliders affect color noise.

Reduces luminance noise.

Controls the luminance noise threshold. Useful for verynoisy photos. Higher values preserve more detail but may producenoisier results. Lower values produce cleaner results but may alsoremove some detail.

Controls luminance contrast. Useful for very noisy photos.Higher values preserve contrast but may produce noisy blotches ormottling. Lower values produce smoother results but may also haveless contrast.

Reduces color noise.

Controls the color noise threshold. Higher values protectthin, detailed color edges but may result in color speckling. Lowervalues remove color speckles but may result in color bleeding.

Note:

To turn off noise reduction, set theSharpening Amount slider to zero or click the Detail panel On/Officon .

Camera lenses can exhibit different types of defects at certain focal lengths, f-stops, and focus distances. You can correct for these apparent lens distortions using the Lens Corrections panel of the Develop module.

Vignetting causes the edges of an image, especially the corners, to be darker than the center. It is particularly noticeable when the photo contains a subject that is supposed to be an even shade or tone, such as the sky in a landscape image.

Barrel distortion causes straight lines to appear to bow outward.

Pincushion distortion causes straight lines to appear to bend inward.

Chromatic aberration Chromatic aberration appears as a color fringe along the edges of objects. It is caused by the failure of the lens to focus different colors to the same spot, aberrations in sensor microlenses, and by flare. Lightroom Classic provides a checkbox to automatically correct blue-yellow and red-green fringes, also known as lateral chromatic aberration.

Lightroom 4.1 and later provides slider controls to correct purple/magenta and green aberration (axial chromatic aberration). Axial chromatic aberration often occurs in images made with large apertures.

The Profile options in the Lens Correctionspanel of the Develop module correct distortions in common cameralenses. The profiles are based on Exif metadata that identifiesthe camera and lens that captured the photo, and the profiles compensateaccordingly.

Lens profiles are saved in the following locations:

/Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/

C:ProgramDataAdobeCameraRawLensProfiles1.0

Photos App For Mac Download

Note:

The lens profiles that are available in the Lens Corrections panel depend on whether you’re adjusting a raw or a non-raw file. For more information and a list of supported lenses, see the Adobe Support article Supported lenses.

In the Lens Corrections panel of the Develop module,click Profile and select Enable Profile Corrections.
To change the profile, select a different Make, Model,or Profile.
Note:
Some cameras have only one lens, and some lenseshave only one profile.
Customize the correction by adjusting the Amount sliders:
The default value 100 applies 100% of the distortioncorrection in the profile. Values over 100 apply greater correctionto the distortion; values under 100 apply less correction to thedistortion.
The default value 100 applies 100% of the vignettingcorrection in the profile. Values over 100 apply greater correctionto vignetting; values under 100 apply less correction to vignetting.
(Optional) To apply your changes to the default profile,click Setup and choose Save New Lens Profile Defaults.

In the Develop module Lens Correction panel,click Color to display the chromatic aberration and defringe controls.

Note:

Toget a better view of the result, zoom in on the image area thatshows the aberration.

For more details about color aberration and how to remove it, see New Color Fringe Correction Controls in the Lightroom Classic Journal.

Click the eyedropper tool in the ColorCorrections Color panel.

Press the spacebar to pan and zoom into the fringe area.(Setting your default zoom to 2:1 or 4:1 helps you view the fringecolors.)

The sliders are automatically adjusted for that color.If you click a color outside of the purple or green hue ranges,you’ll see an error message.

Note:

The end of theeyedropper will change to purple or green if the color under the eyedropperis within the purple or green hue ranges.

Adjust the purple and green Amount slider.The higher the amount, the more color defringing.

Take care not apply an adjustment that affects purpleor green objects in your image.

You can adjust the purpleor green hue range affected by the Amount slider using the PurpleHue and the Green Hue sliders. Drag either end point control to expandor decrease the range of affected colors. Drag between the end point controlsto move the hue range. The minimum space between end points is 10 units.The default spacing for the green sliders is narrow to protect green/yellow imagecolors, like foliage.

Note:

You can protect edges of purple andgreen objects using local adjustment brush. See Remove local colorfringes.

Press the Alt/Option key as you drag any of thesliders to help visualize the adjustment. The fringe color becomesneutral as you drag to remove the color.

Local brush and gradient adjustments removefringes of all colors.

Note:

For best results, perform any Transformlens corrections before applying local color fringe adjustments.

Select the brush or gradient tools and drag inthe image. See Applylocal adjustments.
Adjust the Defringe slider. A plus value removes thecolor fringe. Minus values protect image areas from defringing thatyou apply globally. Minus 100 protects the area from any defringing.For example, applying a strong global purple defringe may desaturateor alter edges of purple objects in your image. Painting with Defringe-100 over those areas will protect them and keep them at their originalcolor.

Note:

Local defringe is available for Process 2012 only.

Transform and vignette corrections can beapplied to original and cropped photo edges. Lens vignettes adjustexposure values to brighten dark corners.

Drag to the right to correct barrel distortion and straightenlines that bend away from the center. Drag to the left to correctpincushion distortion and straighten lines that bend toward thecenter.

corrects perspective caused by tilting the camera upor down. Makes vertical lines appear parallel.

Corrects perspective caused by angling the camera leftor right. Makes horizontal lines parallel.

Corrects for camera tilt. Uses the center of the original,uncropped photo as the axis of rotation.

Adjusts the image scale up or down. Helps to remove emptyareas caused by perspective corrections and distortions. Displaysareas of the image that extend beyond the crop boundary.

Constrains the crop to the image area so that gray borderpixels are not included in the final photo.

Under Lens Vignetting adjust either or both of the following:

Move the Amount slider to the right (positive values)to lighten the corners of the photo. Move the slider to the left(negative values) to darken the corners of the photo.

Drag the Midpoint slider to the left (lower value) toapply the Amount adjustment to a larger area away from the corners.Drag the slider to the right (higher value) to restrict the adjustmentto an area closer to the corners.

To apply a dark or light vignette for artistic effect to a photo, use the Post-Crop Vignetting options in the Effects panel. A postcrop vignette can be applied to a cropped or uncropped photo.

Lightroom Classic postcrop vignette styles adaptively adjust the exposure of the cropped image, preserving the original image contrast and creating a more visually pleasing effect.

In the Post-Crop Vignetting area of the Effectspanel of the Develop module, choose an option from the Style menu:

Enables highlight recovery but can lead to color shiftsin darkened areas of a photo. Suitable for photos with bright imageareas such as clipped specular highlights.

Minimizes color shifts in darkened areas of a photo butcannot perform highlight recovery.

Mixes the cropped image values with black or white pixels.Can result in a flat appearance.

Negative values darken the corners of the photo. Positivevalues lighten the corners.

Lower values apply the Amount adjustment to a largerarea away from the corners. Higher values restrict the adjustmentto an area closer to the corners.

Lower values make the vignette effect more oval. Highervalues make the vignette effect more circular.

Lower values reduce softening between the vignette andthe vignette’s surrounding pixels. Higher values increase the softening.

(Highlight Priority and Color Priority only) Controlsthe degree of highlight contrast preserved when Amount is negative.Suitable for photos with small highlights, such as candles and lamps.

The Grain section of the Effects panel has controls forcreating a stylistic effect reminiscent of particular film stocks.You can also use the Grain effect to mask resampling artifacts.

Windows 10 Retouch Tool

Together, the Size and Roughness controls determine the character ofthe grain. Check grain at varying zoom levels to ensure that thecharacter appears as desired.

Controls the amount of grain applied to the image. Drag tothe right to increase the amount. Set to zero to disable grain.

Controls grain particle size. At sizes of 25 or greater,blue is added to make the effect look better with noise reduction.

Controls the regularity of the grain. Drag to the left tomake the grain more uniform; drag to the right to make the grainmore uneven.

Note:

Beginning with Lightroom Classic CC 7.3 (April 2018 release), the Dehaze slider has been moved from the Effects panel to the Basic panel of Develop module. See Set overall color saturation.

Lightoom Classic lets you easily decrease or increase the amount of haze or fog in a photograph. Once you have made basic adjustments to the photograph, switch to the Effects panel of the Develop module and adjust the Dehaze slider control.

Controls the amount of haze in a photograph. Drag to the right to remove haze; drag to the left to add haze.

Note: Dehaze is also available as a local adjustment. While working with the Radial Filter, Graduated Filter, or the Adjustment Brush, adjust the Dehaze slider control. For more information, see Apply local adjustments and Use the Radial Filter tool.
