    • PHOTSHOP PRESENTATION

    • WHAT IS PHOTOSHOP
      The Adobe Photoshop workspace is arranged to help you focus on creating and editing images The workspace includes menus and a variety of tools and palettes for viewing, editing, and adding elements to your images.
      Adobe Photoshop can open and import many types of graphic file to work effectively.

    • TOPIC
      Color can be described in several ways using a color model such as RGB or CMYK. As you work in your image, you specify colors using one of the color models. In Photoshop you choose the approach to color that’s appropriate for your image and how it’s being use
      HOW TO COLOR BLACK AND WHITE IMAGE
      Color can be described in several ways using a color model such as RGB or CMYK. As you work in your image, you specify colors using one of the color models. In Photoshop you choose the approach to color that’s appropriate for your image and how it’s being used.
      RGB images use three colors, or channels, to reproduce colors on-screen. In 8‑bits-per-channel images, the three channels translate to 24 (8 bits x 3 channels) bits of color information per pixel. With 24‑bit images,
      a bright blue color might have an R value of 0,
      a G value of 8, and a B value of 255.
      MAMTA SAIGAL
    • CMYK Color mode
      In the CMYK mode, each pixel is assigned a percentage value for each of the process
      inks. The lightest (highlight) colors are assigned small percentages of process ink colors;
      CMYK is a standard color model, the exact range of colors represented can vary,
      depending on the press and printing conditions. In CMYK images, pure black is
      generated when all four components have values of 100%.
      Lab Color mode
      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.
      MAMTA SAIGAL
    • Grayscale mode
      Grayscale mode uses different shades of gray in an image. In 8‑bit images, there can
      be up to 256 shades of gray. Every pixel of a grayscale image has a brightness value
      ranging from 0 (black) to 255 (white). In 16 and 32‑bit images, the number of shades
      in an image is much greater than in 8‑bit images.
      Bitmap mode
      Bitmap mode uses one of two color values (black or white) to represent the pixels
      in an image. Images in Bitmap mode are called bitmapped 1‑bit images because
      they have a bit depth of 1.
      Duotone mode
      Duotone mode creates monotone, duotone (two-color), triton (three-color),
      and quad tone (four-color) grayscale images using one to four custom inks.
      MAMTA SAIGAL
    • Indexed Color mode
      Indexed Color mode produces 8‑bit image files with up to 256 colors. When converting
      to indexed color, Photoshop builds a color lookup table (CLUT), which stores and
      indexes the colors in the image. If a color in the original image does not appear in
      the table, the program chooses the closest one or uses dithering to simulate the
      using available colors.
      Multichannel mode
      Multichannel mode images contain 256 levels of gray in each channel and are useful
      for specialized printing. Multichannel mode images can be saved in Photoshop,
      MAMTA SAIGAL
    • Open the photo you want to convert
      MAMTA SAIGAL
    • Convert a color photo to Grayscale mode:
      1- Open the photo you want to convert
      2- Choose Image > Mode > Grayscale
      Convert Grayscale to RGB mode:
      3- Choose Image > Mode > RGB
      Select with the Magnetic Lasso tool
      When you use the Magnetic Lasso tool , the border snaps to the edges of defined
      areas in the image. The Magnetic Lasso tool is not available for 32‑bits-per-channel
      images.

    • Specify one of the selection options in the options bar.
      Selection options A. New B. Add To C. Subtract From D. Intersect With

    • Save and load selections
      Choose Select > Save Selection
      You can save any selection as a mask in a new or existing alpha channel
      and later reload the selection from the mask.
      Load a saved selection
      Choose Select > Load Selection.
      you are loading a saved selection from another image, make sure to open it.
      Also, make sure your destination image is active.

    • Apply the Color Balance command
      MAMTA SAIGAL
    • 1 The Color Balance command changes the overall mixture of colors
      an image for generalized color correction.
      2 Choose Layer > New Adjustment Layer > Color Balance.
      Click OK in the New Layer dialog box.
      3 Select Shadows, Midtones, or Highlights to select the tonal range in which
      you want to focus the changes.
      4 Drag a slider toward a color that you want to increase in the image; drag a slider
      away from a color that you want to decrease in the image. The values above the
      color bars show the color changes for the red, green, and blue channels. (For Lab
      images, the values are for the A and B channels.) Values can range from ‑100 to +100.

    • Apply the Brightness/Contrast command
      The Brightness/Contrast command lets you make simple adjustments to the tonal range of an image. Moving the brightness slider to the right increases tonal values and expands image highlights, to the left decreases values and expands shadows. The contrast slider expands or shrinks the overall range of tonal values in the image.
      1 Choose Layer > New Adjustment Layer > Brightness/Contrast.
      Click OK in the New Layer dialog box.
      2 Drag the sliders to adjust the brightness and contrast. Dragging to the left decreases
      the level, and dragging to the right increases it. The number at the right of each slider
      reflects the brightness or contrast value. Values can range from ‑150 to +150
      for Brightness, ‑50 to +100 for Contrast.

    • Save a file
      You use the Save command to save changes to the current file or Save As to save
      a new version of the current file.
      Save a file in PNG format
      You can use the Save As command to save RGB, Indexed Color, Grayscale
      and Bitmap mode images in PNG format.
