• RAW is good for white balance, contrast, and chromatic aberration
• EV – shortening the exposure time, closing your aperture
• Darkest part set at 128 = midtone
• EXR = 32-bit TIFF. Efficient way of saving HDR image.

Masks

• Don’t use magnetic lasso, use PATHS with the pen tool!
• Hold down command key while you have path tool selected to bring in points
• Hold down option key to create an arrow to rotate lines between points
• The old looking pen thing is the pen tool…paths is located under Layers/Channels/Paths
• Auto Add/Delete  – use this to remove points or to add a point
• Activate the layer to make an adjustment. For example, a color adjustment.  To remove sharp edge,  go to SELECT > Refine Edge.
• CMD + H to hide the “marching ants” (border-y thing)
• If you screw up you can always go back to the master mask.
• Hold down Option and Command keys to select one selection and remove overlapped selection
• Path is a smaller file than a layer
• Cmd + Option + R: Mask menu
• LAB – color space developed in the 1970s.
• CMYK (SWOP) = used for developing plates for printing. it is a narrow color space. Good for press.
• SRGB = generic for screen
• Adobe RGB = Adobe’s…
• ProPhoto RGB = Recommende by Brian. 90% of colors you can get in LAB.
• L stands for Lightness. The value of 1 – 100.  A stands for Magenta/Green. The value of 128 (Magenta) to -128 (Green). B stands for Yellow/Blue. The value to 128 (Yellow) to -128 (Blue).
• Everything you touch a color in RGB you change a value. That does NOT happen in LAB. You can make color changes independent of value.
• PHOTOSHOP: EDIT > Convert to Profile > Destination Space Profile [SELECT LAB].
• You can work in lab then sample down, for example, to AdobeRGB.
• Make an INVERSE of the MASK. Now you have a histogram of, for example, someone’s face. You want to reduce magenta.
• How to lighten a dark dress in LAB: Select Dress > Dupe Background Layer ? Change Blending Mode to SCREEN > (Blends a new layer) > Under Layer Styles remove A and B…keep L (value), thus only screening the value.

How To Reduce Red-Eye

@ Sarah

Red eye reduction is pretty straight forward.
1-using the Marquee tool (m on the keyboard + shift until you get to the ellipse shape).

2- marquee around the red pupil.

3-add a adjustment layer> hue saturation.

4-desaturate the eye.

5- soften the selection using select> refine edges (command option-r).  Use the feather slider to soften the edge transition.

6. if you want to make the pupil darker you can use the brighteness option in hue/saturation. While  I don’t use this adjustment layer to alter value ever, it is such a basic move, the penalty for doing so is low.
