INTRODUCTION
What is Adobe Photoshop
• Photoshop is a graphics editing program used to create and
modify digital images developed and published by Adobe
Systems for Windows and OS.
• Photoshop was created in 1988 by Thomas and John Knoll.
• Can be used to:
 Create original artwork
 Manipulate images
 Retouch photographs
 Repair Damage Images
 Create graphics for website
Why do we use Photoshop?
 You can express yourself creatively.
 You can create different graphic design projects.
 You can restore old photos.
 You can artistically combine graphics with text.
 You can make art works using brushes.
 You can change the color of a picture.
 You can correct photography mistakes.
 You can do T-shirt designs.
 You can transform pictures artistically.
 You can have personal fulfilment.
Features
• The .PSD (Photoshop Document), Photoshop's native
format, stores an image with support for most imaging
options available in Photoshop. These include layers
with masks, color spaces, ICC profiles, transparency,
text, alpha channels and spot colors, clipping paths, and
duotone settings.
• Photoshop has the ability to read and write raster and
vector image formats such as .EPS, .PNG, .GIF, .JPEG,
and Fireworks.
Digital Images
Digital image: Is a representation of a two-dimensional image
using ones and zeros (binary).
• Made up of dots called pixels.
• Depending on whether or not the image resolution is fixed, it
may be of vector or raster type. The term "digital image"
usually refers to raster images.
Image Resolution: Spacing of pixels in an image, measured in
ppi (pixels per inch) or dpi (dots per inch)
Image Size: Physical dimensions of an image, measured in
pixels (width x height)
Understanding Image Pixels
From Your Digital Camera To Your Photo Printer, It's All
About The Pixels
• "pixel", a short form of two words, "picture element“
• the elements which make up our digital pictures.
• what you're really see is a massive collection of colored
squares – too small for the eyes to see, yet the
photograph you're looking on screen

RGB and Color Channels
• you know that every color in a digital image is made
up of some combination of the three primary colors
of light?
RGB and Color Channels
• It doesn't matter what color you're looking at on your
screen. It's being made up of some combination of those
three colors. You may be thinking, "That's impossible!
There's millions of colors in my image.”
• How can you create millions of colors out of just red, green
and blue?"
• By using multiple shades of red, green and blue! The more
shades of each color you have to work with and mix
together, the more colors you can create.
• If all you had was pure red, pure green, and pure blue, the
most you could create would be seven different colors,
including white if you mixed all three together:
RGB and Color Channels
What Does The Term “8-Bit” Mean?
• If you had,256 shades of red, 256 shades of green, and
256 shades of blue - If you do the the math, 256 times
256 times 256 equals roughly 16.8 million.
• That's 16.8 million colors you can now create!
• And that's exactly what you get with an 8-bit image - 256
shades of red, 256 shades of green, and 256 shades of
blue, giving you the millions of possible colors you
usually see in a digital photo

Photoshop has strong
ties with other Adobe
software for media
editing, animation, and
authoring.
Conclusion
• Photoshop is the current market leader for commercial bitmap
and image manipulation software, and is the flagship product of
Adobe Systems.
• Photoshop has strong ties with other Adobe software for media
editing, animation, and authoring.
• Photoshop functionality can be extended by add-on programs
called Photoshop plugins which act like mini-editors that modify
the image.
• A more user-friendly interface and new tools such as the "red-
eye" reduction brush were aimed firmly at the more casual
image editor.
