The main window shows basic toning controls that affect the whole picture - color, brightness, contrast, saturation, etc.
Temperature and Tint - Basic color balance is adjusted using the Temperature and Tint controls at the top. This enables you to shoot in odd-colored light (fluorescent, tungsten, etc.) and correct for it without having first set a color balance in your camera. If you had shot JPGs, for example, the color balance would be "baked" into the file at only one setting.
Exposure - Exposure changes will shift the entire histogram left (darkening) or right (lightening) the picture - within limits. Its action is very much like changing aperture or shutter speed in camera to control light. Use this control with moderation because other controls may be more useful than exposure alone. New in Camera Raw 7 is Exposure behavior that won't blow out highlights or shadows as much as in older versions.
Contrast - Will increase or decrease contrast in the picture. Other controls also affect contrast (Blacks, Fill Light, etc.) so use this carefully. It might undo some of the changes you made in the controls above it.
Beginning with Camera RAW 7, the Exposure and Contrast controls will affect the middle tones more than the extreme white or black tones. This reduces the tendency to blow-out highlights or plug-up shadows (clipping).
Highlights - This control affects only the lighter tones. If you have highlights that are slightly blown out, this control may bring them back into the picture when the slider is moved to the right. Unlike JPGs or TIF files, blown highlight detail in RAW files may be still there, and made visible with this adjustment. This is a huge advantage over TIFs or JPGs.
Shadows - This control acts much like a fill-flash on camera - it lightens the deep shadows. If there are some deep shadows in your picture, slide this control to the right to bring some shadow detail back.
Whites - This is similar to the Highlights control, but targets only the very lightest colors. It provides more aggressive control over them. Use in an emergency when Highlights doesn't provide enough adjustment.
Blacks - Similar to the Shadows control, but it targets only the very darkest tones. It provides more aggressive control over the deepest tones. Use when you can't control the deepest tones using the Shadows control.
Clarity - Consider this tool as a sharpening tool for your picture. Going the other direction will soften the picture, but not always in a pleasant way.
Vibrance - This is a smart Saturation tool that reduces the over-saturated, orange faces, look. Because it applies saturation in an intelligent way, it is more forgiving than the Saturation tool underneath.
Saturation - Will increase or decrease overall saturation of the picture hues. Use wisely and don't oversaturate pictures.
All these controls are reversible. No change is ever made to the original RAW file. Instead, these changes are saved as separate sidecar XMP files that carry the toning information to be overlayed onto the original file. If you wish to return to the original picture as-shot, it is easy to do.
Hot Tip: The Save button in the bottom left of the dialog box will enable you to save your toned raw files as Adobe DNG files if you wish. Adobe DNG files are essentially camera raw files saved together with the toning information normally contained in an XMP file. The toning changes are still reversible at any time, so it shares the same advantages other camera raw files have. Additionally, the DNG files are open source code, and not a proprietary date file like the camera produces. This is a huge benefit for serious archivists that can't rely on camera manufacturers to continually update their own camera raw routines to run on new computer operating systems, etc. One final benefit is that the DNG file, because it contains the original raw information plus the toning file, is only one file to keep track of. It can't become separated from the XMP file, and lose the toning changes made by the user, unless they wish to undo them in the camera raw dialog box.
