Color Correcting Digital Image from camera:
Removing unwanted color cast. [Adjust Color Sampling Tool FIRST as shown in Workshop]
Open image from Camera in Photoshop. Press ctrl+M for Curves. To set color reference for shadow areas, double-click on the black Eyedropper (First from the left) tool at lower right-hand side. A Color Picker will appear. Entering values and applied, it helps to remove color casts.
Enter values in R: 20, G: 20, and B: 20.
To set a preference making the highlight areas neutral, Double-click on the white Eyedropper, the Third Eye dropper.
Enter value: R: 244. G: 244, B: 244.
Set your mid-tone preference: Here Double-click on the mid-tone Eyedropper in the located in the middle of the three Eyedroppers.
Enter values: R: 133, G: 133, B: 133.
Note: We will be using these shortly.
Close the Curves dialog by clicking OK to exit. In the warning dialog, "Save the new target colors as defaults", Click ‘Yes’ to make this your New Default settings.
Marking Darkest & Lightest Points: Now in the Layers palette click on the half-white & half-black circle icon (at the bottom of the pallet) and choose Threshold.
In Threshold dialog, drag the Threshold Level slider all the way to the left. Now slowly drag the Threshold slider back to the right, until the first darkest part of your image appears.
To mark it, Click-and-hold on the Eyedropper tool in the Toolbox, and choose the Color Sampler tool. Click this Color Sampler ONCE on the area that is darkest and a target cursor will mark that spot. When you do this, the Info palette automatically appears onscreen. You don't need this palette right now, so you can close it. Go to the Layers palette and double-click on the adjustment layer thumbnail to bring up the Threshold dialog again, but this time drag the slider all the way to the right. Slowly drag the Threshold slider back toward the left; the first area that appears in white is the lightest part of your image. Click OK, and then click the Color Sampler tool ONCE on the brightest area to mark it as your highlight point.
Color Correction in Image:
In the Layers palette, click-and-drag the adjustment layer onto the Trash to delete it. Image looks normal, but now there are two target markers visible. Press ctrl+M to bring back Corves Dialog box again.
Select the shadow Eyedropper (the one half filled with black) from the bottom right. Taking it to the image, click once directly on the center of the No. 1 target. When you click on the No. 1 target, the shadow areas will be corrected. Note: If image looks nor right then undo and click again that the exact point.
While still in the Curves dialog, switch to the highlight Eyedropper (the one filled with white). Move your cursor over your photo and click once directly on the center of the No. 2 target to assign that as your highlight.
This will correct the highlight colors.

Click the mid-tone Eyedroppe (the middle of the three, half filled with gray) in the image that looks medium gray. This corrects the mid-tones, the difference may be very small, and some images may not have a medium gray. Go ahead and click it once at the spot that is medium gray (if you do have one).
Some Visual Corrections:  In the Curves grid, click on the center of the curve and drag it upward a bit to brighten the mid-tones of the image. It's up to you to determine how much to adjust. This concludes your process of correction to the highlights, mid-tones, and shadows, removing any color casts and brightening the
overall contrast.
Thank you for reading this. The WS reading id a Must before you do this.
