Using the Color Curves to brighten and darken an image is similar to using the color wheel sliders, only incredibly detailed and much more precise. You’ll now see only a white diagonal line on the Color Curves graph. ✓ Click the Brightness checkbox next to the Color Curves if it isn’t already active. Color Curves give you very detailed control over the entire range of darkness and lightness. The Color Curves on the Color Curves tab are by far the most precise way to manage exposure and brighten or darken images. The other tools give you greater precision, but the underlying concept is the same.

This process of brightening the image and lowering the darks to increase contrast is basically the same process employed using the other tools. If you find your whites starting to clip, slide the Contrast Center slider to the right. The darker parts of your image get darker while the brightest parts get a little brighter. ✓ Slide the Contrast slider to the right to increase contrast. The entire image gets brighter, so lower the brightness of the darker elements of the image, not just to manage noise as we said above, but because the darker areas won’t be dark enough for a correct image. Don’t go too high or the image will wash out. The entire image gets brighter the further to the right you go. ✓ Slide the Brightness slider to the right to brighten the image. The Video Event FX window opens, and the Brightness and Contrast controls appear. Drag the default preset thumbnail and drop it on your video event. ✓ In the Video FX window, click Brightness and Contrast. It’s a great effect to start with because what you do with it is basically the same as what you’ll do with every other method of brightening or darkening images, only simplified. Exactly as it says, this effect lets you control the brightness and contrast of the image. The Brightness and Contrast effect offers the simplest way to brighten or darken an image. Then, in post, editors can darken the image precisely to the levels intended for the shot, and there’s far less problem with noise. The results can include soft-looking focus, plastic-looking skin, and smudged colors.ĭarkening a brighter, cleaner image produces less noise than brightening a darker, noisier image, so filmmakers often shoot scenes intended to be dark with a lot of light, producing an image much brighter than they intend the final product to be. Eliminating noise always means eliminating detail, and you’ll lose detail throughout your image, even details you want to keep.

There are software noise reduction programs, and some of them are very effective, but there is always a cost. But whichever way you do it, you lose detail in the darker areas, and some of the details may be lost entirely to pure black. You can lower the Y value in the lows or flatten the lower left of the color curves for more precision. There are a few ways to darken the darker areas directly.

Increasing contrast darkens the darker areas, but it also brightens the brighter areas, so it’s a delicate balance. Making the dark areas darker does help cut noise. You generally don’t find noise in pure black or close to pure black, because that’s easy to resolve.

One way to deal with noise is to make the darker areas as dark as possible while still brightening the rest of the image. Excess noise ruins many effects, and if you add sharpening to the image, you’ll make the noise worse. The upshot for editors is that when they try to brighten darker footage, it ends up with excess noise, which looks bad and makes it difficult to work with the footage. There are denoisers and other ways to deal with noise built into cameras, but as an editor, you’re dealing with footage that’s already recorded, so if the noise is already in the footage, it’s there. You generally find the most noise in the darker areas in about the bottom 40% of the brightness waveform. There isn’t much picture information for the sensor and for the internal compressors to resolve. Noise is random information buzzing around in your image, and while you’ll find some at every brightness level, it’s more likely to be found in the darker areas of images because the camera sensor didn’t have much light to work with. A common problem with dark footage is noise.
