The power of Dehaze
Use Lightroom CC’S powerful new Dehaze slider to enhance detail in misty, washed-out scenes
Lightroom CC’S powerful new Dehaze slider will transform your misty images in minutes..
• Software Photoshop CC or Lightroom CC • Image type A misty, foggy or hazy shot with washed-out detail
Amisty scene is always a delight to shoot as there’s atmosphere in abundance, however the lack of contrast makes for a flat-looking image when viewed straight out of the camera. Lightroom CC – and the latest version of Adobe Camera Raw in Photoshop – now offers users the Dehaze slider. You’ll find it in the Effects tab if you want to make global adjustments, or it can be used with the Graduated filter, Adjustment brush and Radial filter if you want to make local adjustments. It works by altering the contrast in hazy, washed-out areas of an image. You can use it to reduce the captured mist to bring back detail, or you can increase the mist effect to enhance the atmosphere, allowing you to get extra creative with your processing.
1 Import a RAW file into Lightroom and apply Lens Corrections To start you need to Import a RAW file into Lightroom. You’ll find the pic China River.dng in the Start Images folder. Just click Import at the bottom left of the Library module, navigate to the Source of the file, choose Copy and pick a Destination for where you want the RAW file to be saved. Click Import at the bottom right to add the file to the Lightroom Library. Once in, hit Develop to enter the editing module and open the Lens Corrections tab. Tick Enable Profile Corrections and Remove Chromatic Aberration to fix lens distortion. Under Profile check the Nikon 18-200mm f3.5-5.6g ED VRII lens is selected. 2 Control colour and tones in the Basic tab Open the Basic tab and begin by increasing the Temp slider to 5,200 to make the image warmer. Push the Highlights slider to +100 to make these tones brighter as at this start point the dynamic range of the image is very compressed. Increase the Whites slider to +60 to lift the white point and pull Blacks to -60 to add depth to the darker tones. Below within the Presence sliders, set Clarity to -25 to reduce microcontrast add to the soft feel of the image. Push the Vibrance slider to
+40 to add intensity to the more muted colours in the image. 3 Use the Graduated filter to apply Dehaze Select the Graduated filter by clicking on it (or press M for a shortcut) and double-click Effect to reset all the tool sliders. Set Temp to 12, Contrast to 20, Highlights to 50, Shadows to
-50, Clarity to 35, Dehaze to 35, Saturation to 10 and Noise to 50. Click and drag the Graduated filter across the image from the top towards the bottom, with the feather area fading over the river. Click New and double-click Effect to clear the sliders. Set Highlights to -100, Shadows to -70, Whites to 10 and
Dehaze to -20. Pull a Graduated filter from the bottom over the river area, feathering out as it reaches the treeline. Click Done to exit the tool. 4 Customise contrast in the Tone Curve tab Open the Tone Curve tab and click the icon at the bottom right which lets you manually adjust the Point Curve. Select the tool at the top left of the tab which lets you adjust the Point Curve by dragging in the photo. Hover your mouse over a darker area of foliage, then click and drag down to darken these tones: you’ll see a Control Point added to the curve in the shadows. Now hold your mouse over a much lighter area of the foliage, then click and drag up to lighten these tones: again, you’ll see another Control Point added to the curve. To lift the black point, pull the very start of the Point Curve up just a fraction. To make the whites a little brighter, pull the far end of the Point Curve slightly to the left.
5 Remove dust and distractions with the Spot Removal tool
Select the Spot Removal tool from the toolbar (press Q for a shortcut) and set the brush to Heal. Adjust the Size of the tool to suit the object you wish to remove from the image with the scroll-wheel of your mouse. Set Feather to around 35 and Opacity to 100. Click the tool over any sensor dust spots and Lightroom will automatically select a sample area to copy pixels from. If it hasn’t chosen a suitable area you can manually drag the sample area to a new position. To remove longer objects like the overhead wires, you can click and drag the tool to select a larger area. When completed, click Done to finish.
6 Control the colours in the Adjustment tab
Click on the HSL/COLOR/B&W tab, choose Color and click All. Under Yellow, set the Hue to +40 to give the yellow pixels more of a green tint and set Luminance to +40 to make them brighter. Under Green, set Luminance to +40 to make the greens lighter. To make using the Spot Removal tool easier, set Tool Overlay to Selected to hide all of the previous pins, which can prove a little distracting.
7 Set Sharpening and Noise Reduction sliders
Open the Detail tab and use the Target tool to zoom into an area of detail, like the man on the boat. Under Sharpening, set the Amount slider to 100, leave Radius and Detail in their default positions, and set
Masking to 80. Hold Alt as you move the Masking slider to see an edge mask so you know precisely where is being sharpened: set it so only the edges of notable detail has sharpening applied. Under Noise Reduction, set the Luminance slider to 30 to cut back on any grain in the image.
8 Export your pic
To finish editing, you need to Export your image from Lightroom. This creates a new version elsewhere with all the adjustments locked in, leaving the original RAW file untouched, so you can always make as many edits as you like. Simply click Fileexport and select an Export Location, such as your Desktop. Under File Naming select Custom Name and type a name you’d like to give your new file. Under File Settings choose JPEG and set Quality to 80, then click Export to finish.
The start image, found on the CD, suffers from washed-out detail, a lack of contrast and colour, and lots of distracting sensor dust spots.
