These tools are the Graduated Filter, Radial Filter and Adjustment brush. Lightroom incorporates noise reduction with some of the adjustment brushes as well. Generally, I stay around the default values and occasionally add detail under luminance noise (Figs. In short, this reacts similarly to editing the contrast: The less you use, the smoother tones seem side by side adding more causes more distinct, or separated, tones. Contrast is useful for blending areas where opposing tones meet. You definitely do not want to sharpen the noise. This gives you back some of the defined edges in the image, rather than sharpening the noise. Once you find a balance between soft and sharp, you can move the detail slider to the right. 4).Ĭorrecting luminance noise can quickly start to remove detail in your image, as you see I have done (Fig. Luminance noise is a major factor in the noise, or grain, of your images (Fig. This will work out great for reducing the noise for the entire image. Using the same area we corrected for color noise, we have a range of highlights to deep shadow tones. There is evidence of this noise in the entire image. Luminance noise is visually the most obvious in underexposed and high-ISO images. Smoothness does quite the opposite: As you increase the value, a softened effect is applied to the speckled color tones. This means that, as you move the slider to the right, the edge detail increases in color noise. Adjusting the detail slider gives you the ability to control the threshold. Moving below in the detail and smoothness sliders, these default at a value of 50 each. I start by correcting color noise to fix the distracting discolored speckles and keep the clarity in the image. At this point, I like to toggle the Detail panel on and off to see the change. Start by moving the slider to the right and adding the correction effect (Figs. Like sharpening, Adobe Camera Raw defaults color at 25. Under Noise Reduction, skip down to the Color, Detail and Smoothness sliders. We will circle back to this adjustment after we complete noise reduction. You will notice that the Sharpening amount defaults to 25 adjust this to 0 for now. Once you find an area you wish to correct, you can use the Detail panel to begin removal. Usually noise is more prevalent in the underexposed midtones and shadows where large gradients of a color have noise, especially in this night sky. For example, in this night shot zooming in at 2:1, or 200%, the groom’s suit has noticeable color noise (Figs.
#ADOBE LIGHTROOM 5 NOISE REDUCTION PATCH#
When looking in a large, single-colored area, you might notice a fragmented patch of discoloring. There are two kinds of noise: color and luminance. I definitely want to address noise reduction for an entire set of images, but first we need to understand some fundamentals. Taking a step backward, even adjusting one photo can be difficult. Using Lightroom for noise reduction can seem like a daunting task when editing hundreds of photos at a time. After making these adjustments in Lightroom, move down to the Detail panel to silence the noise. No need to worry about image quality-as long as you expose the image properly, you should be fine, right? Noise depends on many factors, but mostly how high you set your ISO, how much you increase exposure in post and whether or not you recover the shadows. Throughout your daylong wedding shoot, you’re going to encounter low light and be forced to throw your camera up into the high-ISO range.

When shooting in Aperture Priority mode, opening up your aperture all the way and seeing the shutter speed has dropped, it’s ISO to the rescue. In post-production, image noise can be almost as distracting as a blurry image. Dustin Lucas – Silence the Noise: Best Practices for Noise Reduction in Lightroom
