Adobe Photoshop CS3
Introduction :
Adobe Photoshop is a raster graphics editor developed and
published by Adobe Systems for macOS and Windows. Photoshop was created in 1988
by Thomas and John Knoll. Since then, it has become the de facto industry
standard in raster graphics editing, such that the word "photoshop"
has become a verb as in "to Photoshop an image,"
"photoshopping" and "photoshop contest", though Adobe
discourages such use. It can edit and compose raster images in multiple layers
and supports masks, alpha compositing and several color models including RGB,
CMYK, CIELAB, spot color and duotone. Photoshop has vast support for graphic
file formats but also uses its own PSD and PSB file formats which support all
the aforementioned features. In addition to raster graphics, it has limited
abilities to edit or render text, vector graphics (especially through clipping
path), 3D graphics and video. Photoshop's feature set can be expanded by
Photoshop plug-ins, programs developed and distributed independently of
Photoshop that can run inside it and offer new or enhanced features.
Photoshop's naming scheme was initially based on version
numbers. However, in October 2002, following the introduction of Creative Suite
branding, each new version of Photoshop was designated with "CS" plus
a number; e.g., the eighth major version of Photoshop was Photoshop CS and the
ninth major version was Photoshop CS2. Photoshop CS3 through CS6 were also
distributed in two different editions: Standard and Extended. In June 2013,
with the introduction of Creative Cloud branding, Photoshop's licensing scheme
was changed to that of software as a service rental model and the
"CS" suffixes were replaced with "CC". Historically,
Photoshop was bundled with additional software such as Adobe ImageReady, Adobe
Fireworks, Adobe Bridge, Adobe Device Central and Adobe Camera RAW.
Alongside Photoshop, Adobe also develops and publishes
Photoshop Elements, Photoshop Lightroom, Photoshop Express and Photoshop Touch.
Collectively, they are branded as "The Adobe Photoshop Family". It is
currently a licensed software.
Early history :
Photoshop was developed in 1987 by the American brothers
Thomas and John Knoll, who sold the distribution license to Adobe Systems
Incorporated in 1988. Thomas Knoll, a PhD student at the University of Michigan,
began writing a program on his Macintosh Plus to display grayscale images on a
monochrome display. This program, called Display, caught the attention of his
brother John Knoll, an Industrial Light & Magic employee, who recommended
that Thomas turn it into a full-fledged image editing program. Thomas took a
six-month break from his studies in 1988 to collaborate with his brother on the
program. Thomas renamed the program ImagePro, but the name was already taken.
Later that year, Thomas renamed his program Photoshop and worked out a
short-term deal with scanner manufacturer Barneyscan to distribute copies of
the program with a slide scanner; a "total of about 200 copies of
Photoshop were shipped" this way.
During
this time, John traveled to Silicon Valley and gave a demonstration of the
program to engineers at Apple and Russell Brown, art director at Adobe. Both
showings were successful, and Adobe decided to purchase the license to distribute
in September 1988. While John worked on plug-ins in California, Thomas remained
in Ann Arbor writing code. Photoshop 1.0 was released on 19 February 1990 for
Macintosh exclusively. The Barneyscan version included advanced color editing
features that were stripped from the first Adobe shipped version. The handling
of color slowly improved with each release from Adobe and Photoshop quickly
became the industry standard in digital color editing. At the time Photoshop
1.0 was released, digital retouching on dedicated high end systems, such as the
Scitex, cost around $300 an hour for basic photo retouching.

File format :
Photoshop files have default file extension as .PSD, which
stands for "Photoshop Document." A PSD file stores an image with
support for most imaging options available in Photoshop. These include layers
with masks, transparency, text, alpha channels and spot colors, clipping paths,
and duotone settings. This is in contrast to many other file formats (e.g.,
.JPG or .GIF) that restrict content to provide streamlined, predictable
functionality. A PSD file has a maximum height and width of 30,000 pixels, and
a length limit of 2 Gigabytes.
Photoshop files sometimes have the file extension .PSB,
which stands for "Photoshop Big" (also known as "large document
format"). A PSB file extends the PSD file format, increasing the maximum
height and width to 300,000 pixels and the length limit to around 4 Exabytes.
The dimension limit was apparently chosen arbitrarily by Adobe, not based on
computer arithmetic constraints (it is not close to a power of two, as is
30,000) but for ease of software testing. PSD and PSB formats are documented.
Plugins :
- Photoshop functionality can be extended by add-on programs called Photoshop plugins (or plug-ins). Adobe creates some plugins, such as Adobe Camera Raw, but third-party companies develop most plugins, according to Adobe's specifications. Some are free and some are commercial software. Most plugins work with only Photoshop or Photoshop-compatible hosts, but a few can also be run as standalone applications.
- There are various types of plugins, such as filter, export, import, selection, color correction, and automation. The most popular plugins are the filter plugins (also known as a 8bf plugins), available under the Filter menu in Photoshop. Filter plugins can either modify the current image or create content. Below are some popular types of plugins, and some well-known companies associated with them:
- Color correction plugins (Alien Skin Software, Nik Software, OnOne Software, Topaz Labs Software, The Plugin Site, etc.).
- Special effects plugins (Alien Skin Software, Auto FX Software, AV Bros., Flaming Pear Software, etc.).
- 3D effects plugins (Andromeda Software, Strata, etc.).
- Adobe Camera Raw (also known as ACR and Camera Raw) is a special plugin, supplied free by Adobe, used primarily to read and process raw image files so that the resultant images can be processed by Photoshop.[22] It can also be used from within Adobe Bridge.
- Adobe Photoshop CS3 Update is the official patch for the world’s most famous graphics editor, Adobe Photoshop. This update improves stability and responsiveness for Adobe’s flagship product. The fixes and enhancements included in the Adobe Photoshop CS3 Update focus on avoiding occasional crashes that may ruin your work, and also on optimizing management of multiple layer images. The Print menu is also improved. To install the Adobe Photoshop CS3 Update, make sure you know where your copy of Adobe Photoshop is installed. You’ll also need to temporarily disable your antivirus software. Adobe Photoshop CS3 Update brings a bunch of optimizations, fixes and enhancements to Adobe’s popular photo editor.
Photoshop tools :
Upon loading Photoshop, a sidebar with a variety of tools
with multiple image-editing functions appears to the left of the screen. These
tools typically fall under the categories of drawing; painting; measuring and
navigation; selection; typing; and retouching. Some tools contain a small
triangle in the bottom right of the toolbox icon. These can be expanded to
reveal similar tools. While newer versions of Photoshop are updated to include
new tools and features, several recurring tools that exist in most versions are
discussed below.
 |
| Pen Tool |
Pen tool.
Photoshop includes a few versions of the pen tool. The pen
tool creates precise paths that can be manipulated using anchor points. The
free form pen tool allows the user to draw paths freehand, and with the
magnetic pen tool, the drawn path attaches closely to outlines of objects in an
image, which is useful for isolating them from a background.
 |
| Stamp Tool |
Clone Stamp Tool.
The Clone Stamp tool duplicates one part of an image to
another part of the same image by way of a brush. The duplication is either in
full or in part depending on the mode. You can also clone part of one layer to
another layer. The Clone Stamp tool is useful for duplicating objects or
removing a defect in an image.
Shape tools. Photoshop provides an array of shape tools including
rectangles, rounded rectangles, ellipses, polygons and lines. These shapes can
be manipulated by the pen tool, direct selection tool etc. to make vector
graphics.
Measuring and navigation. The eyedropper tool selects a color from an area of the
image that is clicked, and samples it for future use. The hand tool navigates
an image by moving it in any direction, and the zoom tool enlarges the part of
an image that is clicked on, allowing for a closer view.
Selection tools. Selection tools are used to select all or any part of a
picture to perform cut, copy, edit, or retouching operations.
Cropping. The crop tool can be used to select a particular area of an
image and discard the portions outside the chosen section. This tool assists in
creating a focus point on an image and unnecessary or excess space. Cropping
allows enhancement of a photo’s composition while decreasing the file size. The
"crop" tool is in the tools palette, which is located on the right
side of the document. By placing the cursor over the image, the user can drag
the cursor to the desired area. Once the Enter key is pressed, the area outside
the rectangle will be cropped. The area outside the rectangle is the discarded
data, which allows for the file size to be decreased. The "crop" tool
can alternatively be used to extend the canvas size by clicking and dragging
outside the existing image borders.
Slicing. The "slice" and slice select tools, like the crop
tool, are used in isolating parts of images. The slice tool can be used to
divide an image into different sections, and these separate parts can be used
as pieces of a web page design once HTML and CSS are applied. The slice select
tool allows sliced sections of an image to be adjusted and shifted.
Moving. The move tool can be used to drag the entirety of a single
layer or more if they are selected. Alternatively, once an area of an image is
highlighted, the move tool can be used to manually relocate the selected piece
to anywhere on the canvas.
Marquee. The marquee is a tool that can make selections that are
single row, single column, rectangular and elliptical. An area that has been
selected can be edited without affecting the rest of the image. This tool can
also crop an image; it allows for better control. In contrast to the crop tool,
the "marquee" tool allows for more adjustments to the selected area
before cropping. The only marquee tool that does not allow cropping is the
elliptical. Although the single row and column marquee tools allow for
cropping, they are not ideal, because they only crop a line. The rectangular
marquee tool is the preferred option. Once the tool has been selected, dragging
the tool across the desired area will select it. The selected area will be
outlined by dotted lines, referred to as "marching ants". These
dotted lines are called "marching ants", because the dashes look like
ants marching around the selected area. To set a specific size or ratio, the
tool option bar provides these settings. Before selecting an area, the desired
size or ratio must be set by adjusting the width and height. Any changes such
as color, filters, location, etc. should be made before cropping. To crop the
selection, the user must go to image tab and select crop.
Lasso. The lasso tool is similar to the "marquee" tool, however,
the user can make a custom selection by drawing it freehand. There are three
options for the "lasso" tool – regular, polygonal, and magnetic. The
regular "lasso" tool allows the user to have drawing capabilities.
Photoshop will complete the selection once the mouse button is released. The
user may also complete the selection by connecting the end point to the
starting point. The "marching ants" will indicate if a selection has
been made. The "polygonal lasso" tool will draw only straight lines,
which makes it an ideal choice for images with many straight lines. Unlike the
regular "lasso" tool, the user must continually click around the
image to outline the shape. To complete the selection, the user must connect
the end point to the starting point just like the regular lasso tool.
"Magnetic lasso" tool is considered the smart tool. It can do the
same as the other two, but it can also detect the edges of an image once the
user selects a starting point. It detects by examining the color pixels as the
cursor move over the desired area. A pixel is the smallest element in an image.
Closing the selection is the same as the other two, which should also should
display the "marching ants" once the selection has been closed.
The quick selection tool selects areas based on edges,
similarly to the magnetic lasso tool. The difference between this tool and the
lasso tool is that there is no starting and ending point. Since there isn’t a
starting and ending point, the selected area can be added onto as much as
possible without starting over. By dragging the cursor over the desired area,
the quick selection tool detects the edges of the image. The "marching
ants" allow the user to know what is currently being selected. Once the
user is done, the selected area can be edited without affecting the rest of the
image. One of the features that makes this tool especially user friendly is
that the SHIFT key is not needed to add more to the selection; by default,
extra mouse clicks will be added to the selection rather than creating a new
selection.
Magic wand. The magic wand tool selects areas based on pixels of similar
values. One click will select all neighboring pixels of similar value within a
tolerance level set by the user. If the eyedropper tool is selected in the
options bar, then the magic wand can determine the value needed to evaluate the
pixels; this is based on the sample size setting in the eyedropper tool. This
tool is inferior to the quick selection tool which works much the same but with
much better results and more intuitive controls. The user must decide what
settings to use or if the image is right for this tool.
Eraser. The Eraser tool erases content based on the active layer. If
the user is on the text layer, then any text across which the tool is dragged
will be erased. The eraser will convert the pixels to transparent, unless the
background layer is selected. The size and style of the eraser can be selected
in the options bar. This tool is unique in that it can take the form of the
paintbrush and pencil tools. In addition to the straight eraser tool, there are
two more available options – background eraser and magic eraser. The background
eraser deletes any part of the image that is on the edge of an object. This
tool is often used to extract objects from the background. The magic eraser
tool deletes based on similar colored pixels. It is very similar to the magic
wand tool. This tool is ideal for deleting areas with the same color or tone
that contrasts with the rest of the image.
Video editing. In Adobe CS5 Extended edition, video editing is
comprehensive and efficient with a broad compatibility of video file formats
such as MOV, AVI, MPEG-4, and FLV formats and easy workflow. Using simple
combination of keys video layers can easily be modified, with other features
such as adding text and the creation of animations using single images.
3D extrusion. With the Extended version of Photoshop CS5, 2D elements of
an artwork can easily become three-dimensional with the click of a button.
Extrusions of texts, an available library of materials for three-dimensional,
and even wrapping two-dimensional images around 3D geometry.
Mobile integration. Third-party plugins have also been added to the most recent
version of Photoshop where technologies such as the iPad have integrated the
software with different types of applications. Applications like the Adobe
Eazel painting app allows the user to easily create paintings with their
fingertips and use an array of different paint from dry to wet in order to
create rich color blending.
Camera Raw. With the Camera Raw plug-in, raw images can be processed
without the use of Adobe Photoshop Lightroom, along with other image file
formats such as JPEGs, TIFFs, or PNGs. The plug-in allows users to remove noise
without the side-effect of over-sharpening, add grain, and even perform
post-crop vignetting.
3D printing tools. Requiring Photoshop version 14.1 or later, users can create
and edit designs for 3D printing. After downloading 3D photo models from
numerous online services, users can add color, adjust the shape or rotate the
angles. Artists can also design 3D models from scratch.
Color replacement tool. The Color Replacement Tool allows you to change the color,
while maintaining the highlights and shadows of the original image, of pieces
of the image. By selecting Brushs and right clicking, the Color Replacement
Tool is the third option down. What is important to note with this tool is the
foreground color. The foreground color is what will be applied when painting
along the chosen part of the image with the Color Replacement tool.
