Smoothens or accentuates textured details in your photo. Move the slider to the left to smoothen details; move it to the right to accentuate details. When you adjust the Texture slider, the color or tonality does not change.

Adds depth to an image by increasing local contrast. To maximize the effect, increase the setting until you see halos near the edge details of the image, and then reduce the setting slightly.

When using this setting, it is best to zoom in to 100% or greater. To zoom in, double-tap the photo or use the outward spread gesture.

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

Applies a dark or light vignette for artistic effect to a photo. Negative values darken the corners of the photo. Positive values lighten the corners.

For related useful information, see Vignette, grain, and dehaze effects.

Adds realistic film-grain effect to your photos. Drag the slider to the right to add grain. When you add grain, you can also control the grain size and roughness using the Size and Roughness sliders respectively.  

In the Edit panel in the Loupe view, tap Details icon at the bottom of the screen.

Note:

When applying selective edits, only Noise and Sharpness controls are available in the Detail menu.

Adjust any of the following controls:

Sharpening controls

• Sharpening: Adjusts edge definition. Increase the slider value to increase sharpening. A value of zero (0) turns off sharpening. In general, set the slider to a lower value for cleaner images. The adjustment locates pixels that differ from surrounding pixels based on the threshold you specify and increases the pixels’ contrast by the amount you specify.
• Radius: Adjusts the size of the details that sharpening is applied to. Photos with very fine details may need a lower radius setting. Photos with larger details may be able to use a larger radius. Using too large a radius generally results in unnatural-looking results.
• Detail: Adjusts how much high-frequency information is sharpened in the image and how much the sharpening process emphasizes edges. Lower settings primarily sharpen edges to remove blurring. Higher values are useful for making the textures in the image more pronounced.
• Masking: Controls an edge mask. With a setting of zero (0), everything in the image receives the same amount of sharpening. With a setting of 100, sharpening is mostly restricted to those areas near the strongest edges.

Luminance noise reduction controls

• Noise Reduction: Increase the slider value to reduce luminance noise.
• Detail: Controls the luminance noise threshold. Useful for very noisy photos. Higher values preserve more detail but may produce noisier results. Lower values produce cleaner results but may also remove some detail.
• Contrast: Controls luminance contrast. Useful for very noisy photos. Higher values preserve contrast but may produce noisy blotches or mottling. Lower values produce smoother results but may also have less contrast.

Color noise reduction controls

• Color Noise Reduction: Increase the slider value to reduce color noise.
• Detail: Controls the color noise threshold. Higher values protect thin, detailed color edges but may result in color speckling. Lower values remove color speckles but may result in color bleeding.
• Smoothness: Controls how much smoothing to apply to the image as you reduce the color noise.  

In the Edit panel in the Loupe view, tap Optics icon at the bottom of the screen.

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.

To remove chromatic aberration in your selected photo, enable Remove Chromatic Aberration option in the Optics panel.

Lightroom for mobile includes numerous lens profiles, which can be used to correct common lens aberrations such as geometric distortion and vignetting. The profiles are based on metadata that identifies the camera and lens used to capture the photo, and then compensates accordingly.

Enable Lens Profile Corrections option in the Optics panel to automatically select a matching lens profile based on the camera model, focal length, f-stop and focus distance information in your photo's metadata.

Cameras with built-in lens profile support 
Lens correction for all Micro 4/3 (MFT) lenses and cameras, including Panasonic, Olympus, and other cameras (Fuji X, Leica Q, plus many point-and-shoot models from Canon) happens automatically without your interaction. If your lens is supported automatically, Lightroom for mobile displays the message Built-in Lens Profile Applied in the Optics panel.

(Optional) If Lightroom for mobile is unable to find a matching lens profile automatically, do the following:

1. Tap Manually Select a Profile.
   
2. In the Lens Profile panel, select a Make, Model, and Profile.

If you want to change the matching lens profile applied by Lightroom automatically, do the following:

1. Tap the current lens profile name.
   
2. In the Lens Profile panel, select a Make, Model, and Profile.
   If you want to revert to the matching lens profile automatically applied by Lightroom, tap Auto Select.

The lens profiles that are available depend on whether you’re adjusting a raw or a non-raw file. For a list of supported lenses, see Supported lenses.

You can customize the correction applied by the profile by adjusting the following sliders below lens profile:

The default value 100 applies 100% of the distortion correction in the profile. Values over 100 apply greater correction to the distortion; values under 100 apply less correction to the distortion.

The default value 100 applies 100% of the vignetting correction in the profile. Values over 100 apply  greater  correction to vignetting; values under 100 apply less correction to vignetting.

Select a photo with skewed geometry.

(Recommended) In the Edit panel in the Loupe view, tap the Optics icon at the bottom of the screen, enable the Lens Profile Corrections option.

Tap the Geometry icon at the bottom of the screen.

From the Upright menu, choose an option to apply the correction to the photo:

• Guided: Allows you to draw two to four guides on your photo to adjust perspective.
• Auto: Corrects both vertical and horizontal perspective while balancing the overall image, preserving as much of the visible image area as possible.
• Level: Corrects horizontal perspective, making horizontal lines parallel in the photo.
  
• Vertical: Corrects vertical perspective caused by tilting the camera up or down. Makes vertical lines parallel in the photo.
  
• Full: Combines Auto, Level, and Vertical upright modes to automatically correct perspective.
  

Cycle through the Upright modes until you find the most preferable setting.

All the Upright modes correct distortion and perspective errors. The best setting varies from one photo to another. Experiment with the modes before deciding on the best possible mode for your photo.

Guided Upright mode

If you chose the Guided Upright mode, do the following:

(Optional) While correcting the perspective of your photo, you may get white areas near the image boundaries. To remove the white area, enable the Constrain Crop option, which automatically crops the photo according to the original dimension.

Use the geometry sliders to fine-tune the perspective corrections - Distortion, Vertical, Horizontal, Rotate, Aspect, Scale, X Offset, Y Offset.

• Distortion: Corrects lens barrel distortion (straight lines appearing to bow outward) and pincushion distortion (straight lines appearing to bend inward). Move the slider to the right to correct barrel distortion in your photo; move the slider to the right to correct pincushion distortion.
• Vertical: Makes vertical lines in an image parallel. If the vertical lines are diverging at the bottom edge, move the slider to the left to push the pixels away from that edge; if the vertical lines are diverging at the top edge, move the slider to the right to push the pixels away from that edge.
• Horizontal: Makes horizontal lines in an image parallel. Move the slider to the left to push the pixels away from the right edge; move the slider to the right to push the pixels away from the left edge.
• Rotate: Rotates the image to correct for camera tilt. Move the slider to the left to rotate the image anti-clockwise; move the slider to the right to rotate the image clockwise.
• Aspect: Move the slider to the left to widen the perspective of the photo; move the slider to the right to narrow the perspective of the photo.
  
• Scale: Adjusts the photo scale up or down while maintaining the aspect ratio. Move the slider to the left to scale down; move the slider to the right to scale up.
  
• X Offset: Move the slider to the left to shift the image pixels toward left on the x-axis, leaving a white area at the right edge; move the slider to the right to shift the image pixels toward right on the x-axis, leaving a white area at the left edge.
• Y Offset: Move the slider to the left to shift the image pixels downward on the y-axis, leaving a white area at the top edge; move the slider to the right to shift the image pixels upward on the y-axis, leaving a white area at the bottom edge.
