12 - Other Panels on the Right Side
Let's look—briefly—at the other panels on the right side of the Develop
Module.
There are three panels.
Lenses may create the three errors below.
The Lens Corrections panel can make corrections
automatically.
Error #1 - Distortion
Lenses, especially wide-angle lenses, create distortion.
Architecture
The distortion is evident when photographing architecture.
Let's say you're photographing in Rockefeller Center.
You point your camera up, and photograph the buildings.
The buildings appear to get smaller.
Their lines converge.
This is perspective distortion.
Landscapes
Distortion may appear in a landscape as a curved horizon
line.
Horizons are not curved unless you're high enough to see the
curvature of the earth!
Caution with Portraits
Use a focal length of 70mm to 100mm with most digital SLR
cameras.
Don't use other focal lengths, especially wide angle.
Don't use the Lens Corrections panel without checking if the
corrections are desired.
Error #2 - Chromatic Aberration
Lenses may produce
chromatic aberration.
This occurs when the colors in a scene are not uniformly
focused on the sensor.
If the red light is not focused on the sensor, a red fringe
may appear along edges of color or tone in the photograph.
Error #3 - Vignetting
Lenses, especially wide-angle lenses, may not project an
image on the sensor with uniform brightness.
The corners may be darkened, vignetted.
If any of the above errors are present, read on.
Profile
By default, the Lens Corrections panel is set to Profile.
Select Enable Profile Corrections to automatically make
corrections based on the camera, lens, and focal length that you
used.
You can tweak the corrections with the sliders.
Manual
Click Manual if you want to make all corrections manually.
Use Both
You can start with Profile, and can then make further
corrections in Manual.
You can add two effects with this panel.
Effect #1 - Post-crop Vignetting
Vignetting darkens or lightens the edges of a photograph.
Post-crop vignetting maintains the effect even if
you crop the photograph later.
Style
There are three styles.
Highlight Priority is similar to the Recovery slider in the
basic panel.
Color Priority reduces color shifts in the darkened
areas of the photograph.
Paint Overlay blends the photograph with black or white.
Vignette Choices
Amount
You can choose the tone of the vignette.
Midpoint
The Midpoint slider adjusts the size of the vignetted area.
Roundness
You can shift the shape of the vignette from circular to oval
to rectangular.
Feather
Feathering is the degree to which the vignette fades along
its inner perimeter.
Highlights
You can brighten and darken highlights when using a dark
vignette with the Highlight Priority or Color Priority styles.
Effect #2 - Grain
Grain simulates the grain of high-ISO films such as Tri-x.
The three sliders, Amount, Size, and Roughness, are
self-explanatory.
Your camera develops the raw information from the sensor into
a JPEG.
You can select several developing styles, such as:
• Neutral
• Standard
• Landscape
• Vivid
• Portrait
When you open a raw file in Lightroom, you can apply the
above settings to the file using this panel.
