As the popularity and importance of color correction grows, more and more vendors are getting color correction products into the market or beefing up the capabilities of the products that are already there. Despite the rapidly changing and expanding marketplace, this chapter will provide an explanation of color correction capabilities for some of the most popular desktop products and platforms. We’ll leave the “big iron” products out of the discussion for now and focus just on products under $10,000.
We’ll start with the built-in capabilities of some of the most popular editing applications and then cover some of the plug-ins that also have specialized color correction tools. We’ll primarily focus on the specific tools that help you utilize the information in the first couple of chapters. We’ll stay away from filters that provide preset looks because that pushes the boundary between color correction and effects work.
Adobe Premiere offers a nice array of color correction tools built in to the basic software. Premiere and After Effects both ship with versions of Synthetic Aperture’s Color Finesse, which is a very powerful, dedicated color correction plug-in and probably the Adobe user’s best choice for serious color correction. (See the Color Finesse heading later in this chapter for more on Color Finesse’s capabilities.)
In addition to using Color Finesse, Premiere and After Effects both have other color correction effects. In Premiere these are in Effects > Video Effects. There are three folders with subcategories of effects that are applicable to color correction: Adjust, Color Correction, and Image Control (Figure 11-1).
Most of the effects in the Adjust folder are automatic effects. Though there are times when using these may be appropriate or helpful under tight deadlines, I won’t discuss them in more depth here because they’re basically “drag and drop” solutions.
The Color Correction folder has most of the effects you’ll want to access.
The Image Control folder has a few additional effects, but these are mainly poor versions of effects that are in the Adjust and Color Correction folders. I have the feeling that this folder is a “legacy” folder that was left in place so that longtime Premiere users will know where certain effects are. In any case, the effects in this folder are:
The effects for color correction in Adobe After Effects are a little more centrally located (see Figure 11-3). These are all the same as the effects just described for Premiere. Adobe tries—whenever possible—to have similar user interfaces and effects between all of its products to make it easier to transition between them. Some of the differences in effects are due to the nature of After Effects as an animation and motion design tool, so even though the effects are in the color correction menu, they’re really more design tools, like Color Link, which allows you to colorize a layer based on the average color of the pixels from another layer. That’s not really applicable in color correction. There are a few effects that are different between the two applications though:
Additionally, as of CS3, Adobe Photoshop has the ability to deal with video, and all of its powerful image processing tools can be used to do color correction. Video can be imported, turned into Smart Objects, and manipulated just like a still image.
Since the introduction of Avid Xpress Pro 3.5, Avid has ported a good deal of the power of their excellent color correction mode from Avid Symphony down into the rest of the Avid line, including Adrenaline and Media Composer. These are accessed from the Toolset menu. By clicking on Color Correction, the entire UI reconfigures to a new set of tools specifically designed to put all of the color correction tools you need in one place. The two main tabs are HSL and Curves. In the HSL tab are two more tabs. One is called Controls, and one is called Hue Offsets.
Controls offers the basic TBC controls, Hue, Saturation, Brightness, Contrast, and Clipping controls. There are also color matching controls that allow you to sample colors from reference frames to match colors from scene to scene. I never use the controls in this tab except for Saturation. Instead, use the controls in the Hue Offset tab.
The Hue Offsets tab (Figure 11-4) includes three Hue Offset wheels, one for each luminance range, but none for overall Hue Offset. Additionally, it includes controls for gain, gamma, and setup. Also on this tab is another set of color matching controls. For quick fixes, this is the tab where you can get the most done with the least work.
In the Curves tab, there are four different curves, one for each primary color plus a master curve. There is also another set of color matching controls. The color matching controls on each tab offer a slightly different capability, especially the one in the Curves tab, which provides a function called Natural Match. All of these tabs have buttons called Color Buckets that allow the user to save various setups for quick recall and reuse from shot to shot.
In addition to the easily accessible Buckets, an unlimited number of corrections can be saved in a bin. These corrections can then be named and used from the bin, like any Avid effect, by dragging and dropping. The naming convention for color corrections is usually to name it after the clip that it corrected, but it can also be a simple description of what the correction does, such as “crushed blacks, cool gamma” or “Kurtis blue fix.”
Apple Color has been discussed in pretty thorough depth throughout this book. This application—for Mac only—is a very deep application that has a very thorough toolset organized into rooms, which would be referred to as Tabs in just about any other application. The rooms include:
Synthetic Aperture is everywhere. It is a powerful standalone application for color correction, similar to Apple Color, but it is also a plug-in for Final Cut, After Effects, and Premiere, among others (Figure 11-6). It has many useful features that make it an excellent tool, even when used as a plug-in to applications that already have substantial color correction horsepower. One reason for using Color Finesse within these apps is that you can execute all your corrections with a single filter.
Color Finesse has a very complete range of tools with which to inspect and analyze the footage. There are software waveform and vectorscopes built into Color Finesse. Sampling colors with an eye-dropper is an excellent way to analyze your footage. Color Finesse provides this common feature and adds the ability to choose a single pixel or an averaged sample from a 3 × 3 pixel area, a 5 × 5 pixel area, or a 9 × 9 pixel area. Another nice feature is the Reference Gallery, which allows you to have access to a list of images that can be used as references for matching colors from one shot to the next. They are available across all projects, which is very convenient. You can use this feature for clients who have approved a certain color for their products or a certain skin tone for talent. (This stuff happens, believe me!) When it has been approved for one project, you can then match that color for any other projects. Matching skin tones from one scene to the next is as easy as clicking with an eyedropper using Color Finesse’s Color Matching feature. This is a great thing for people looking for more automated corrections. You can also use the eyedropper in the Curves tab to set white balance, black balance, and gray balance. This is a quick and intuitive way to get rid of color casts and to set basic levels.
For more hands-on specific, manual control of your image, there are a wide range of choices that closely match the capability of Avid Symphony. There are Hue Offset wheels, Levels, and Curves, in addition to the standard HSL controls. All of these controls can be applied to specific luminance ranges of the picture, providing excellent control.
Internally, Final Cut Pro provides most of its color correction effects through the Effects Menu > Video Filters > Color Correction path. The main tools that you’ll access from here are the Color Corrector and 3-Way Color Corrector (Figure 11-7). FCP also offers a set of scopes, including a histogram and parade waveform, which are accessed through the Windows > VidScopes. These scopes can be arranged in various configurations and, best of all, can be expanded to full-screen size. There are also color correction options in the Effects Menu > Video Filters > Image Control path, which was the main path for color correction before FCP version 3.
Under Image Control, Brightness and Contrast there are simple sliders for general control across the entire image. Color Balance provides sliders for R, G, and B levels for highlights, midtones, and shadows. Gamma/Pedestal/Gain provides sliders for gamma, pedestal, and gain in each of the color channels. Also, Levels provides sliders for master RGB and individual R, G, and B color channels with control similar to that of an editable histogram. Finally, the Proc Amp controls give the basic TBC-like controls that many editors are used to: Setup, Video, Chroma, and Phase.
In the first edition of this book, plug-ins were much more important because editing software was just beginning to provide the capabilities that the plug-ins allowed. Plug-ins still allow some functionality not provided by the color correction tools built in to the software. Plug-ins can also help make a more effortless transition between editing or compositing applications by using a color correction application that works as a plug-in in both applications.
Boris offers a number of color correction options in addition to the 3D effects for which Boris is best known. It allows brightness and contrast control and master RGB color controls. It also offers basic TBC control through the Color Correction filter and Gamma Control filters. Boris also has a set of plug-ins called Boris Continuum Complete, which includes a color correction plug-in that provides brightness, contrast, hue, saturation, output black, and output white controls. Also, the Pixelchooser gives many options for applying secondary-like qualifications to very specific portions of the picture based on a list of matte-generating features, as well as the ability to selectively mix the correction back with the original image.
Digital Film Tools’ Composite Suite offers basic HSL (hue/saturation/luminance) control plus sliders for gamma and overall RGB sliders. Additionally, there are RGB sliders for shadows, midtones, and highlights as well as a feature called Flash Amount. This is terminology borrowed from cinematography and describes the optical process of brightening and lowering the contrast of an image by flashing it with light. Basically, Flash Amount just adds a simple tint to the image and is done by choosing a color with an eyedropper or RGB sliders. Digital Film Tools’ full Composite Suite package provides these color correction capabilities. They also have a color correction only package called Composite Suite Color Correct.
GenArts’ Sapphire package also has some color correction capabilities. Sapphire does not put all of its color-related controls together in one effect, so you must stack several individual effects to have full control. For creating interesting looks, Sapphire does have a lot of options for blending effects in unique ways.
Bleach Bypass
Sometimes called Skip Bleach, Bleach Bypass is a film developing process where the bleaching process is skipped. Without the bleaching process, film acquires a contrasty, low saturation look because the silver (black) is left on the film along with the film dyes. The look is similar to laying a black and white image on top of a full-color image.
Noise Industries has several color correction effects as part of an extensive collection of effects (Figure 11-8). These include Vignettes, Bleach Bypass, Color Temperature, Day for Night, Filmic, and others.
The Advanced Vignette allows similar functionality to the Vignette tool in Apple Color without having to leave Final Cut Pro. Bleach Bypass lets you create the classic film process look in post-production with parameters that control the contrast and gamma and provide a couple of preset looks.
The basic Colorista effect is so similar to the color correction controls in Final Cut, Avid, and Premiere that there’s not much I can say to recommend it because it seems to work slower than the built-in effects of those applications, but if you want to experiment with some of the techniques in this book that use the individual sliders for each tonal range of each color channel and your application (FCP or Avid) doesn’t have them, then the Colorista (sliders) effect is just what you need. It’s similar to the Advanced Tab of the Primary In room of Apple Color.
3Prong’s color correction offering for Avid AVX, ColorFiX provides lots of control for isolating colors and luminance ranges. It also allows the image to be re-white balanced and re-black balanced using eyedroppers. ColorFiX has two sets of controls that it calls paths. The Main path provides overall color correction and the Select path is more closely related to secondary color correction, allowing for the replacement of specific colors with different colors without affecting the rest of the image. The controls in this plug-in are very advanced and provide very detailed control,allowing corrections to one part of a picture, such as shadow, to be done without affecting other areas. Also, the Color Difference controls allow for unusual color vector movement that is not available in any other plug-in.
