Here are my notes from Brian’s workshop!
- 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.
