Adobe Camera RAW - Using the HSL/Grayscale Tab

For Adobe Camera RAW user, who usually uses the basics tab to tweak white balance, improve specific areas of exposure and contrast, making your image to look more sharp, crisp, and vibrant when needed.



But how about the HSL / Grayscale Tab?
Well, this article that I found at Geoff Lawrence's website, might be helpful for all of you.

It actually written and submitted by Don Moughamian, as Geoff said on his website.

The Hues Tab

The first of our HSL tabs focuses on Hues (or regions of specific color). Moving one of the eight hue sliders can (if the hue is present in your image) shift that specific color region to a different but directly related hue. Again, you might decide to make an area of green more yellow-green or more blue-green. Or, maybe you wish to make a region of orange more red-orange or more yellow-orange.

The Saturation Tab

We will look at the Saturation tab. As mentioned in the previous section, saturation effects the purity of a specific region of color. Saturation controls are common in image editing software but very few products offer the level of control and non-destructive benefits of the HSL panel in Adobe Camera Raw.

The Lumincance Tab
Luminance refers to the lightness or perceived brightness of the colors we are targeting in the HSL panel. One more, you need to adjust only those sliders which have an effect in the Hue and Saturation tabs, and in many cases you may only need to adjust one or two of them.

Enjoy experimenting.

Proccesing Images With RAW

Written by Sabina


A raw image file contains unprocessed or unmodified data straight from the camera’s sensor. A raw file obtained from a digital camera is the equivalent of the negative image of film photography, it has all the necessary information to create an image. In the past, only expensive professional cameras were able to save images in a raw format. Nowadays, more and more digital cameras offer you this option. By saving your pictures in raw format, you will analyze the image taken and make the necessary adjustments. By comparison, by saving a picture in a compressed format (JPEG), you let the camera’s internal algorithms deal with the image’s characteristics. By choosing to shoot raw, you can use editing software (such as Adobe Photoshop) to set the image’s settings: white balance, tonal range, contrast or the amount of sharpening.

In conformity with the camera used to take the picture, the resulting raw file will have different extensions: .nef (for Nikon cameras), or .crw (for Canon cameras). You can use import the raw formats from many camera manufacturers into Adobe Photoshop for further editing. Adobe Camera Raw (ACR) is the Photoshop’s component which allows you to process the raw files.

When you start editing a raw camera file, Photoshop does not alter the initial file content. After you have performed the desired modifications, you export the edited image and in this way the original remains unchanged.

You can open raw files with both Adobe Photoshop and Adobe Bridge, as they have the identical Camera Raw dialog box.
