Digital design uses computer technology as part of the creative process. It includes graphic, web, and interaction design. Digital images are electronic representations of scenes or documents that are sampled and mapped as a grid of pixels, each assigned a value represented in binary code. Digital imaging is the creation of images digitally, ranging from simple elements to complex photography. A digital designer combines skills like graphic design, photography, and coding to design visual content for digital platforms. They work across many roles including graphic, web, and motion design. Photo media and imaging involve capturing and manipulating photographic assets for visual art and design. Key terminology in digital imaging includes resolution, pixel dimensions, bit depth, dynamic range, file size, compression, and file formats.

4. SO IS DESIGN…

6. • Digital Design is an creative work practice that uses digital computer technology as
an essential part of the creative process. It is about the interplay between people,
computers and culture. Digital Design is an evolving and exciting multi-disciplinary
field that underlies many of today’s fast-growing industries: from information to
communication, from advertising to entertainment. It is everywhere.
• There are countless types of digital design. The most common use of the term refers
to graphic, digital graphic and web design that includes digital imaging, animation,
coding, interface design, interaction design and more.

7. WHAT IS A DIGITAL IMAGE?
• Digital images are electronic snapshots taken of a scene or scanned from
documents, such as photographs, manuscripts, printed texts and artwork. The
digital image is sampled and mapped as a grid of dots or picture elements
(pixels). Each pixel is assigned a tonal value, which is represented in binary
code (zeros and ones). The binary digits ("bits") for each pixel are stored in a
sequence by a computer and often reduced to a mathematical representation.
The bits are then interpreted and read by the computer to produce an analog
version for display or printing.

8. WHAT IS A DIGITAL IMAGING?
• Digital imaging is the creation of photographic images. It ranges from the
creation web banners, simple navigation elements such as buttons to complex
photo modulating and/or the creation of artistic imagery from scratch.
• Digital imaging was developed in the 1960s and 1970s for scientific and
military missions. As digital technology became cheaper in later decades, it
replaced the old film methods for many purposes. In 1957, Russell A. Kirsch
produced a device that generated digital data that could be stored in a
computer; this used a drum scanner and photomultiplier tube.

9. WHAT IS A DIGITAL IMAGING?
• In the early 1960s, while developing compact, lightweight, portable equipment for the
onboard non-destructive testing of naval aircraft, Frederick G. Weighart and James F.
McNulty at Automation Industries, Inc., co-invented the first apparatus to generate a digital
image in real-time which image was a fluoroscopic digital radiograph. Square wave signals
were detected on the fluorescent screen of a fluoroscope to create the image.
• These different scanning ideas were the basis of the first designs of digital camera. Early
cameras took a long time to capture an image and were poorly suited for consumer purposes.
It wasn’t until the development of the CCD (charge-coupled device) that the digital camera
really took off. The CCD became part of the imaging systems used in telescopes, the first
black and white digital cameras and camcorders in the 1980s. Color was eventually added
to the CCD and is a usual feature of cameras today.

10. WHO IS A DIGITAL DESIGNER?
• A digital designer is a creative who combines graphic design skills with
imagination and technology to produce a large range of visual media from
advertisements to websites, digital images to animation, 2D and 3D modelling
and graphics. Basically a digital designer is responsible for how something
looks on a digital platforms and devices such as on computers, mobile phones
or in video. A perfect blend of creativity and technology, the role of a digital
designer uses both the technical mind and the creative spirit to create a visual
world that influences current aesthetics and trends.

11. WHAT DOES A DIGITAL DESIGNER DO?
• A digital designer combines photography, videography, animation and graphic
design skills together to transform ideas and concepts into reality. A digital designer
has options to work as Digital Graphic Designer | Web Designer | Game Designer
| Interface Designer | Interactive Designer | Animator | Motion Artist | Photo
Editor | Videographer to name a few…
• Digital Designers need to meet the challenges of new technologies, keep pace with
the internet of things and more savvy audiences. Digital design brings new types of
production collaborations too. They need to work with a code developer to turn
visual ideas into functioning software applications.

12. WHAT IS PHOTO MEDIA?
• Photo Media is a photographic asset used for visual art and design purposes.
It may be a simple untouched photo or an image that has been manipulated
to change its appearance in any way. It encompasses of traditional and
digital photography as well as image capture by scanning.
• Photo Media emphasises on conceptual and practical investigations through
projects designed to foster individual interpretations and aesthetic
development and to promote the acquisition of technical skills and enhance
your engagement with research.

13. WHAT IS PHOTO IMAGING?
• Photo imaging, also known as image editing, retouching, image manipulation
or colloquially as "Photoshopping," is the process of altering images. It can be
done with modern digital techniques or with traditional analog processes.
Photo imaging, as it relates to graphic/digital design practices is unique in the
expression of design ideas.
• We will be focusing on the capturing and digitising of images as well as the
application of creative explorations into commercial outcomes.

14. BASIC TERMINOLOGY USED IN DIGITAL IMAGING
• RESOLUTION is the ability to distinguish fine spatial detail. Dots-per-inch
(dpi) or pixels-per-inch (ppi) are common and synonymous terms used to
convey the resolution of digital images.
• PIXEL DIMENSIONS are the horizontal and vertical measurements of an
image expressed in pixels. The pixel dimensions may be determined by
multiplying both the width and the height by the dpi. Example: An 8" x 10"
document that is scanned at 300 dpi has the pixel dimensions of 2,400 pixels
(8" x 300 dpi) by 3,000 pixels (10" x 300 dpi).

15. • BIT DEPTH is determined by the number of bits used to define each pixel. The
greater the bit depth, the greater the number of tones (grayscale or color) that can
be represented. Digital images may be produced in black and white (bitonal),
grayscale, or color.
• A bitonal image is represented by pixels consisting of 1 bit each, which can represent
two tones (typically black and white), using the values 0 for black and 1 for white or
vice versa. A grayscale image is composed of pixels represented by multiple bits of
information, typically ranging from 2 to 8 bits or more. A color image is typically
represented by a bit depth ranging from 8 to 24 or higher.
BASIC TERMINOLOGY

16. • DYNAMIC RANGE is the range of tonal difference between the lightest light
and darkest dark of an image.
• Dynamic range also describes a digital system's ability to reproduce tonal
information. This capability is most important for continuous-tone documents
that exhibit smoothly varying tones, and for photographs it may be the single
most important aspect of image quality.
BASIC TERMINOLOGY

17. • FILE SIZE is calculated by multiplying the surface area of a document (height x
width) to be scanned by the bit depth and the dpi2. Because image file size is
represented in bytes, which are made up of 8 bits, divide this figure by 8.
• COMPRESSION is used to reduce image file size for storage, processing, and
transmission.
• FILE FORMATS consist of information on how to read and interpret the file. File
formats vary in terms of resolution, bit-depth, color capabilities and support for
compression and metadata.
• We will discuss this terms in detail and also use them in our work as we go ahead.
