Adobe Camera Raw Basics

Adobe Camera Raw is a Photoshop plug-in that reads RAW files, JPEG and TIFF images previously edited in other programs and reads metadata changes that occurred within them. It also detects any metadata modifications made elsewhere within these applications related to each image file.

Camera Raw utilizes many of the same tools found in Photoshop, yet has been tailored specifically for photographers’ editing workflow. Edits made in Camera Raw are stored in small XMP sidecar files and easily accessible for future editing work.

Tonal Adjustments

These sliders generally help expand an image’s tonal range. Dragging them to either end will darken or lighten it; typically these adjustments are made in increments equivalent to f-stops; moving an exposure slider by one-half stop is equivalent to widening aperture by two and a half stops.

Recovers detail from overexposed highlights without lowering midtone contrast or causing image clipping (the shifting of pixels values towards either their highest highlight value or lowest shadow value, where no image detail exists). Similar to Photoshop’s Fill Light function or After Effects’ Shadow/Highlight filter and effect.

Saturates image colors by increasing saturation in lower-saturated ones while diminishing its effect on higher-saturated hues – similar to Lightroom and Photoshop’s saturation slider settings.

Increase contrast between an image’s lighter and darker tones for enhanced image details when working with low dynamic range images. This setting can help bring out hidden details within low dynamic range images.

Reduces chroma noise (color artifacts) in an image, particularly noticeable in flesh tones and other highly saturated colors. This filter-like adjustment can be applied only to certain parts of an image or applied across all of them at once.

Tip: Hold down the Alt (Option on Mac) key while you adjust Tone sliders, to see where image clipping is occurring: black indicates areas that have been clipped while white areas do not. This tip is particularly helpful when adjusting Exposure and Clarity sliders.

To apply a modification to a specific part of a photo, use the targeted adjustment brush tool resembling a plain paintbrush and drag over the part you would like adjusted.

Noise Reduction

Adobe Camera Raw and Lightroom both provide excellent tools to reduce noise in images – the Detail panel offers tools that reduce both luminance (light/dark) and color noise, with global or targeted applications using masking capabilities. You can add further manual noise reduction by manipulating Sharpening, Texture, and Grain sliders.

Noise reduction is particularly useful for images shot with smaller sensors (such as drones) to prevent aliasing and hot pixels. Lightroom offers excellent noise reduction features in Camera Raw; additionally Denoise provides an effective AI-powered tool which far outshone older manual noise removal techniques.

Camera Raw offers one of the key advantages over Photoshop by storing “Snapshots,” snapshots of an image which you can refer back to later in editing process. They’re stored as an XMP file on disk and will apply to subsequent photos you open from that catalog – an invaluable advantage over just editing directly onto original files themselves.

Camera Raw offers many advantages for image editors, one being its instant ability to instantly synchronize settings across multiple files at the same time. This can save time when editing multiple versions of an identical photo at once if adjustments had to be repeated manually for each.

Denoise, an intelligent automated noise reduction tool, makes it simple and quick to improve any image without overdoing it. Be cautious when using Denoise with your images – applying early in your workflow ensures any enhancements such as sharpening and texture enhancements will take effect based on an ideal image without artifacts being introduced by later applied adjustments.

Sharpening

Camera Raw allows users to sharpen images by enhancing details that may have become obscured during lens or processing steps, bringing back fine details which may have become lost over time. The Detail panel’s controls let you control how much and where sharpening is applied. A mask allows you to fine-tune how it affects flat areas in an image – perfect for using finer-tuned edits that only apply sharpening where needed; The radius control determines the size of area to which sharpening occurs, with smaller settings offering more natural-looking results while larger values might produce dramatic yet less natural-looking results.

Adjustments you make with Camera Raw are stored as metadata either in an accompanying sidecar file (XMP), in a database, or embedded directly into an image if DNG format is selected. This approach gives you flexibility in your workflow by preserving all edits; however, you must save and manage XMP files if you wish to revert back to an earlier stage in editing.

If you don’t need to reprocess your photos in Lightroom or Photoshop, storing your Camera Raw adjustments as a preset and applying them with one click could save time and be especially helpful for photographers working with images from multiple cameras or shooting conditions.

Color Correction

The Color tab houses settings that adjust the colors and tones in your photos. You can use the White Balance tool to set an image’s white point (at which color of white objects becomes neutral) while Hue and Saturation sliders enable you to control intensity levels for primary colors in an image.

The Preview image on the right side of the Camera Raw dialog box displays the results of your adjustments as a ribbon-style histogram. This histogram shows pixel values across red, green and blue color channels – pixels close to white will appear near its left edge; similarly pixels close to black may be closer to its right side. If there are an excessive number of light or dark pixels within either channel then this indicates an skewed histogram and needs adjustments accordingly.

Temperature and Tint controls allow you to precisely adjust a photo’s color temperature, measured in Kelvins. A photo’s hue identifies what kind of lighting was used in its scene. Digital cameras record white balance settings used at exposure as part of its metadata file; when opening an image file using Camera Raw plug-in this metadata information is read back from digital camera storage devices and used to apply its initial white balance settings automatically.

Lens Corrections in Camera Raw offers adjustments that reduce chromatic aberration in an image, such as purple-yellow fringes around specular highlights found in water or polished metal surfaces. There’s even an easy check box and sliders feature available to remove them altogether!

White Balance

White balance settings determine how warm or cool an image appears and affect all colors within it. For instance, taking photos in natural lighting under overcast conditions produces images with an underlying blue cast; on the other hand, indoor photography taken under fluorescent or tungsten lighting produces images with yellow or green tints.

White Balance adjustments provide presets that adjust color temperature and tint according to common lighting scenarios (daylight, shade, tungsten, fluorescent). Most photographs typically produce satisfactory results using one of these settings; however, you can fine-tune colors by moving Temperature or Tint sliders right or left.

Use the Targeted White Balance tool to customize a custom white balance. Clicking an area within your preview image that contains neutral gray or white shades such as the eyes in a portrait, or highlights on your wedding gown, can quickly achieve optimal white balancing results.

Once you’ve created a customized white balance, it can easily be applied to other photos. Camera Raw saves these adjustments either within the database associated with an image file, or as sidecar XMP metadata files which accompany each file (you can also save with an Enhance-NR filename extension for easy management.).

If you have made other adjustments in Camera Raw (such as tweaking tone curves or using Auto Tone Adjustments), it may be useful to apply them across all of your images before applying a custom white balance setting. This way, all adjustments will remain consistent throughout your editing workflow and help ensure synergy among them. For automatic tone adjustments select Auto in Basic tab.
