2. Pixel and Resolution
Image resolution is the detail an image holds. The term applies to raster
digital images, film images, and other types of images. Higher resolution
means more image detail. Image resolution can be measured in various ways.
Basically, resolution quantifies how close lines can be to each other and still
be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per
mm, lines per inch), to the overall size of a picture (lines per picture height,
also known simply as lines, TV lines, or TVL), or to angular subtenant.
Pixel art is a form of digital art, created through the use of raster graphics
software, where images are edited on the pixel level. Graphics in most old (or
relatively limited) computer, console, graphing calculator and mobile phone
video games are mostly pixel art.
3. Vector and Raster Images
Vector graphics is the use of geometrical primitives such as
points, lines, curves, and shapes or polygon, which are all based on
mathematical expressions, to represent images in computer graphics.
"Vector", in this context, implies more than a straight line toward align.

In computer graphics, a raster graphics image, or bitmap, is a dot matrix data
structure representing a generally rectangular grid of pixels, or points of
colour, viewable via a monitor, paper, or other display medium. Raster images
are stored in image files with varying formats.

4. File Formats
The BMP file format, also known as bitmap image file or device independent
bitmap (DIB) file format or simply a bitmap, is a raster graphics image file
format used to store bitmap digital images, independently of the display
device (such as a graphics adapter), especially on Microsoft Windows and
OS/2 operating systems.

Portable Network Graphics is a raster graphics file format that supports
lossless data compression. PNG was created as an improved, non-patented
replacement for Graphics Interchange Format (GIF), and is the most used
lossless image compression format on the World Wide Web.

5. The Graphics Interchange Format is a bitmap image format that was
introduced by CompuServe in 1987 and has since come into widespread
usage on the World Wide Web due to its wide support and portability.

TIFF (originally standing for Tagged Image File Format) is a file format for
storing images, popular among graphic artists, the publishing industry, and
both amateur and professional photographers in general. As of 2009, it is
under the control of Adobe Systems.

6. In computing, JPEG is a commonly used method of lossy compression for
digital photography (image). The degree of compression can be adjusted,
allowing a selectable trade-off between storage size and image quality. JPEG
typically achieves 10:1 compression with little perceptible loss in image
quality.

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 colours, clipping paths, and
duotone settings

7. Portable Document Format (PDF) is a file format used to represent
documents in a manner independent of application software, hardware, and
operating systems.

Encapsulated PostScript, or EPS, is a DSC-conforming PostScript document
with additional restrictions which is intended to be usable as a graphics file
format.

Adobe Illustrator Artwork (AI) is a proprietary file format developed by Adobe
Systems for representing single-page vector-based drawings in either the EPS
or PDF formats. The .ai filename extension is used by Adobe Illustrator.

8. Compression
In computer science and information theory, data compression, source
coding, or bit-rate reduction involves encoding information using fewer bits
than the original representation. Compression can be either lossy or lossless.
Lossless compression reduces bits by identifying and eliminating statistical
redundancy.

9. Image Capture Devices
Image Capture is an application program from Apple that enables users to
upload pictures from digital cameras or scanners which are either connected
directly to the computer or the network. It provides no organizational tools
like iPhoto but is useful for collating pictures from a variety of sources with no
need for drivers.
There are many different devices that can be used to capture images and
videos in a range of different quality's from 1080p – 240p. Obliviously the
better quality etc. the more the device will cost the user.

10. Optimising
In computer science, program optimization or software optimization is the
process of modifying a software system to make some aspect of it work more
efficiently or use fewer resources. In general, a computer program may be
optimized so that it executes more rapidly, or is capable of operating with less
memory storage or other resources, or draw less power.

11. Storage and Asset Management
Digital asset management (DAM) consists of management tasks and decisions
surrounding the ingestion, annotation, cataloguing, storage, retrieval and
distribution of digital assets. Digital photographs, animations, videos and
music exemplify the target areas of media asset management (a sub-category
of DAM).Digital asset management systems (DAMS) include computer
software and hardware systems that aid in the process of digital asset
management.
