Photo Adjustments - Using LAB color

Answer:

1. A- Greens and Reds
2. B- blues and yellows
3. Lightness is the values in the picture

Lab color separates the values from the colors and that is why it is better to use for color enhancements or for just the values in your picture.

1. L for luminance and a and b for the color-opponent (L = 0 yields black and L= 100 indicates white, its position between red/magenta and green a, negative values indicate green while positive values indicate magenta and its position between yellow and blue b, negative values indicate blue and positive values indicate yellow)

2. it makes the colors in the picture's colors more vibrant and makes the picture all around look better and can create some pretty cool effects

Here they are:
1) L stands for Lightness
A represents all the colors between magenta and green
B represents all the colors between yellow and blue
2) LAB color is beneficial because it allows you to create all the colors that you could in RGB and CMYK combined, and it does not create much of a difference when switched to CMYK for printing like RGB will.

Well there you have it: exactly what LAB color stands for and why it is beneficial to use.

Answers to Questions:

1)  The three types of changes that can be made to the colors of a photo when using the LAB color technique.

2)  It brings out a better picture when dealing with the beginnings of revamping a photo. 

1. The first channel is Lightness (L).

    The a channel contains colors ranging from green to red

    The b channel contains colors ranging from blue to yellow

2. The brightness is separate from the color 

1. L stands for lightness, a stands for all the colors between magenta and green, and b stands for every color between yellow and blue

2. LAB will sharpen without color artifacts and will be smoother 

1.  lightness, a is red-green colors, and b is blue-yellow colors.

2.  lab shows colors closer to how the human eye sees them... so the colors are more vivid. 

1. they are channels, and the l stands for luminous, and it controls the lightness and darkness.  The a channel controls the green and magenta colors.  the b controls the yellow and blue colors.

2. “is the most complete color model used conventionally to describe all the colors visible to the human eye.”

The Lab Color mode has a lightness component (L) that can range from 0 to 100. In the Adobe Color Picker and Color palette, the a component (green-red axis) and the b component (blue-yellow axis) can range from +127 to –128.

The CIE L*a*b* color model (Lab) is based on the human perception of color. The numeric values in Lab describe all the colors that a person with normal vision sees. Because Lab describes how a color looks rather than how much of a particular colorant is needed for a device (such as a monitor, desktop printer, or digital camera) to produce colors, Lab is considered to be a device-independent color model. Color management systems use Lab as a color reference to predictably transform a color from one color space to another color space.
