The document outlines the processes and tools involved in photo editing, including analog methods and various graphic software programs. It details types of image formats, features of image editors, and distinguishes between photo editing and photo manipulation, highlighting ethical concerns in image manipulation. Additionally, it explains fundamental concepts such as raster and vector images, image selection tools, and editing techniques for enhancing images.

1. IMAGING & DESIGN FOR
ONLINE ENVIRONMENT

2. PHOTO EDITING
• Photo editing encompasses the processes of altering images,
whether they are digital photographs, traditional photo
chemical photographs, or illustrations.
• Traditional analog image editing is known as photo
retouching, using tools such as an airbrush to modify
photographs, or editing illustrations with any traditional art
medium.

3. GRAPHIC SOFTWARE PROGRAMS
• Which can be broadly grouped into vector graphics editors,
raster graphics editors, and 3D modelers are the primary tools
with which a user may manipulate, enhance, and transform
images.

4. BASIC OF IMAGE EDITING

5. 1. RASTER IMAGES
• are stored in a computer in the form of a grid of picture
elements or pixels.

6. 2. VECTOR IMAGES
• such as Adobe Illustrator, Inkscape and etc. are used to create
and modify vector images, which are stored as descriptions of
lines, Bezier curves and text instead of pixels.

8. 3. 3D MODELING (OR MODELLING)
• is the process of developing a mathematical representation of
any three dimensional surface of an object via specialized
software.
• The product is called a 3D model.

9. IMAGE FORMATS
• JPEG is a commonly used method of lossy compression for
digital images, particularly for those images produced by a
digital photography.
• PNG (PORTABLE NETWORK GRAPHICS) is a raster graphics file
format that supports lossless data compression.
• GIF a lossless format for image files that supports both
animated and static images.
• BMP is a raster graphics image used to store bitmap digital
images

10. IMAGE FORMATS (CONTD.)
• EPS used in vector-based images in Adobe Illustrator.
• SVG is an XML-based vector image format for two-dimensional
graphics w/ support for interactivity and animation
• .3ds is one of the file formats used by the Autodesk 3Ds Max
3D Modelling, animation and rendering software.
• .fbx is an exchange format, in particular for interoperability
between Autodesk products and other digital content creation
software

11. FEATURES OF IMAGE EDITORS

12. • SELECTION One of the prerequisites for many of the app
mentioned below is a method of selecting part(s) of an image,
thus applying a change selectively without affecting the entire
picture
• MARQUEE TOOL for selecting rectangular or other regular
polygon-shaped regions
• LASSO TOOL for freehand selection of a region
• MAGIC WAND TOOL selects objects or regions in the image
defined by proximity of color or luminance

13. • LAYERS which are analogous to sheets of transparent acetate,
stacked on top of each other, each capable of being individually
positioned, altered and blended with the layers below, w/o
affecting any of the elements on the other layers.

14. • IMAGE SIZE resize images in a process often called image
scaling, making them larger, or smaller. High image resolution
cameras can produce large images which are often reduced in
size for Internet use.
• CROPPING creates a new image by selecting a desired
rectangular portion from the image being cropped. The
unwanted part of the image is discarded. Image cropping does
not reduce the resolution of the area cropped.

15. • CLONING uses the current brush to copy from an image or
pattern. It has many uses: one of the most important is to
repair problem areas in digital photos.

16. • IMAGE ORIENTATION - Image editors are capable of altering an
image to be rotated in any direction and to any degree. Mirror
images can be created and images can be horizontally flipped
or vertically flopped. Rotated image usually require cropping
afterwards, in order to remove the resulting gaps at the image
edges.

17. • PERSPECTIVE - is the art of drawing solid objects on a two-
dimensional surface so as to give the right impression of their
height, width, depth and position in relation to each other
when viewed from a particular point.

18. • SATURATION- is an expression for the relative bandwidth of
the visible output from a light source. As saturation increase,
colors appear more “pure.’’ As saturation decreases, colors
appear more ‘’ washed-out.’’

19. • CONTRAST AND BRIGHTENING
• Contrast of images and brighten or darken the image.
Underexposed images can be often be improved by using this
feature.
• Brightening lightens the image so the photo brightens up.
Brightness is a relative expression of the intensity of the energy
output of a visible light source.

20. • PHOTO MANIPULATION
• Photo manipulation involves transforming or altering a
photograph using various methods and techniques to achieve
desired results. Some photo manipulations are considered
skillful artwork while others are frowned upon as unethical
practices, especially when used to deceive the public, such as
hat used for political propaganda , or to make a product or
person look better.

21. PHOTO EDITING VS PHOTO MANIPULATION
• PHOTO EDITING – signifies the
regular process used to
enhance photos and to create
them ‘’Actual editing simple
process’’. Also includes some
of the regular programs used
for editing and expose how to
use them.
• PHOTO MANIPULATION – includes all
simple editing techniques and have
some manipulation techniques like
erasing, adding objects , adding some
graphical effects, background
correction, creating incredible effect,
change elements in an image, adding
styles , eliminating blemishes from a
person’s face and changing the features
of a person’s body.
