What this class is about:
In P354 youll be making graphics and animations for television and digital filmmaking projects. By the end of the semester you should have built a portfolio of graphics and animations.
This is a production class, focusing on the tools and techniques used to make graphics and animations. The main tools used will be Photoshop and After Effects.
Review syllabus, schedule, critique forms & assignments
Important note concerning graphics and audible/visual design elements: Always keep the design of your work 100% original and maintain legal integrity. While there are times that it's appropriate to incorporate existing artwork into your projects (animating a logo for a company), please consider this carefully. Your projects must highlight what you can do- not what others can do. You must rely on your own creativity and design skills- not existing images and clip art.
Examples:
Carry out the Biographical Sketch and Tech Survey Canvas assignments
Student introductions
Graphics Overview
What are we looking at when we see graphics on TV or in the theatre? Maybe it's a keyed lower third, sports statistics, a spaceship, or someone shooting fire from their eyes.
Use in Live Production:
Graphics software like Photoshop and After Effects can function with or without dedicated graphic hardware, however neither is designed for real-time use in production. Graphics systems used for live production typically work with dedicated and sometimes proprietary hardware.
Character generators are designed for real time "live" TV production. Weather map systems, sports replay and virtual studio environments are all offshoots and are optimized for live production.
Pre & Post Production:
Image processing, paint & drawing programs are not intended for live production but let users create new and process existing artwork (Adobe Illustrator, Photoshop, etc.). Photoshop is likely the most useful and used software in the world of web, print, multimedia and video. (If you are serious about design, your time learning Photoshop will be well-spent.)
3D modeling & layout programs let you create three-dimensional objects and animate them in 3D space. If you see an object from alternate sides, chances are good it was made in a 3D program.
Movies like Star Wars, X-Men, etc. rely on programs like Lightwave, Maya, Softimage and 3D Studio Max to create the ships, people and places. But it's not just for sci-fi. More and more productions are using 3D to create organic, or real-life looking places, animals, and people.
Compositing and animation programs (such as After Effects) allow users to combine and animate separate elements into a single whole. For example, actors shot against a green screen could be superimposed onto a rooftop deck, behind this a city skyline, and then behind this a night sky. Adding a virtual camera move to match a real camera dolly could create for a very dynamic composite with lots of depth. On the higher end are special effects and 3D compositing software like Autodesk Maya or workstations with Autodesk Flame.
Compositing and animation programs also allow for the creation of new elements.
After Effects works in 3D space but with flat, 2D objects (postcards in space).
Color
Color can be objectively described in a number of ways. One of the most common methods is using the HSB model:
Hue (the actual color)
Saturation (the strength or intensity, or how far it’s removed from gray)
Brightness (how dark or light)
Color Modes
But you can also describe color in other ways- depending on what color mode you are working in. Two color modes you should be familiar with are:
Additive Color (RGB)
Subtractive Color (CMYK)
Additive Color is the color system used for computer graphics, TV and lighting design. This is the color mode used to create graphics for TV and web. It's referred to as additive since lights are mixed or combined to make the various colors.
- Red
- Green
- Blue
The primary colors (think of them as light sources) are:
Mix them together and you get white.
Subtractive Color is the color system used for printing. It's referred to as subtractive because the colors absorb (subtract) some light and reflect others.
- Cyan
- Magenta
- Yellow
The primary colors (think paints or inks) are:
Mix them together and you get black. (K stands for "key" or black plate.)
Bitmap and Vector graphics
Bitmap or raster images, use a grid or array of pixels to represent an image. The grid is made up of squares or pixels. Each pixel is given a specific color and brightness. If you enlarge a bitmap graphic, you will eventually see the grid.
Photos you take with your phone or DSLR, scanned images, and captured video frames are examples of bitmap graphics.
Vector graphics are made up of shapes, lines and curves that are defined mathematically.
When you draw a circle or create a piece of text with a vector-based application (such as Adobe Illustrator), it keeps track of the lines and angles that make up objects. From this mathematical data, it draws the display. We can scale a piece of vector artwork up to any size, and it will still retain its quality.
Fonts or typefaces are examples of vector graphic objects. You can scale fonts up as much as you want and the edges will never become jagged.
Anti-aliasing
You can turn this feature on and off. It produces intermediately shaded pixels to smooth out the appearance of jagged edges. Note the anti-aliasing which is apparent on the enlarged image on the right hand side.
Typefaces
Text is the most important element used to convey information in graphics. Whether a lower third, the price of a product, stock market figures crawling across the screen, or the final scrolling credits at the end of a production, knowing how to properly use text is essential to graphic production.
It's also possible to make compelling pieces of art based primarily on text. Check out these examples:
- http://vimeo.com/3829682 ("Like, you know" written by Taylor Mali)
- http://www.youtube.com/watch?v=6mnvvVi4HaI (based on Lock, Stock & 2 Smoking Barrels dialog)
Serif and Sans-serif
Serifs are small details found on the end of some fonts. In typography we can describe a font as either serif or sans-serif. (Sans means without.)
Arial and Helvetica are examples of sans serif typefaces.
Times and Courier are examples of seriffed typefaces.
Typographers generally believe that large blocks of text are more easily read by using a seriffed typeface. This is why books, newspapers and magazines primarily use seriffed typefaces in the main body of text.
Tracking, kerning & leading
Tracking refers to the horizontal spacing of an entire group of letters on the same line.
Kerning is the space between individual letters. For example youd want to kern a small case letter o to fit underneath the capital letter T.
Leading (pronounced like bedding) is the vertical spacing between lines of text.
File Formats:
Photoshop lets you work on and save in a number of different color modes and file formats. If you open a file in Photoshop and select "Save As" from the file menu, you will get a screen similar to this:
- Photoshop (.PSD) is the default file format and can support multiple layers and alpha channels.
- BMP (BitMaPped) is a Windows compatible image format (supports alpha channels)
- Compuserve GIF (Graphics Interchange Format) only supports up to 256 colors (web-friendly & supports alpha channels).
- Dicom (Digital Imaging and Communications in Medicine) is a standard for viewing and viewing medical imaging files.
- EPS Encapsulated PostScript: Can describe both vector & bitmapped
graphics.
Support by virtually all page layout and desktop publishing programs - FXG (Flash XML Graphic)
- IFF (Interchange File Format) was developed by Electronic Arts
- JPEG: (.JPG) Joint Photographic Experts Group: uses variable compression (*lossy).
(Web-friendly but no alpha channels.) Does support 24 bit (true) color.
- * Lossy vs lossless: Whenever you open something (like a JPEG) and save it again it loses some detail. This is know as lossy.
- PCX (Personal Computer eXchange): PC based image format developed for PC Paintbrush
- Photoshop (.PDF) Portable Document Format: Used by Adobe Acrobat. No alpha channel support. Notable as it's widely used for both web and print.
- Photoshop Raw: A format with unprocessed (raw) data from digital cameras and film scanners.
- PICT (.PCT) - Was widely used on Macs (Supports 24-bit color and alpha channels) but fallen out of favor.
- Pixar: graphic file type developed by Pixar
- PNG (Portable Network Graphic): Supports 24 bit color. (web friendly - supports alpha channels)
- Portable Bit Map: A format designed to facilitate transfering of B&W images via ASCI text
- Scitex: Developed for Scitex equipment used mainly in desktop publishing.
- TIFF (.TIF) tagged image file format: Widely used by all image apps (Supports alpha channels)
- Targa (.TGA) Video format designed around Targa cards. Supported by most PC-based graphic applications. 32-bit color. Supports alpha channels.
- Photoshop DCS (Desktop color separation) based on EPS fiels, used for desktop publishing.
(File formats in bold are commonly used.)
Message
Graphics are a form of visual communication. They convey a message. TV graphics should be clear and easy to understand.
The graphics we make in this class should have a purpose or a message. We are focused on Applied Art, not Fine Art.
Aesthetics
Understanding of the tools (E.g. Photoshop & After Effects) is great but not worth much without a working knowledge of design and composition. The TV graphics we make should look good, but what is good? What makes up a pleasing composition?
Like painting or photography, TV and film are 2-dimensional images presented within a rectangular frame. There are creative design principles that have been developed over the years in regard to visual composition, which can be described as the orderly arrangement of elements within a scene. The same rules that apply to classic art similarly can be applied to our TV/film graphics.
Subjective and objective analysis for judging the aesthetics of TV graphics is weak. While personal opinions will always vary, Ive identified some general guidelines that serve as a good starting point.
Make sure you are familiar with Jim's Graphic Guidelines!
For those looking for a good visual design book I recommend Robin William's Non-Designer's Design Book. This is a wonderful, inexpensive primer on how to approach layout. Four basic principles include:
- Contrast
- Repetition
- Alignment
- Proximity
Some good examples to ponder:

- Adobe Photoshop Tour of the Inerface (5 minutes)
- Adobe Photoshop CC Help PDF
Photoshop Tour
- Main interface
- Tools (keyboard shortcuts, foreground background etc)
- Tool option bar
- Windows (remember the small arrow on right hand side)
- Navigator, options, info
- Swatches, colors, brushes
- Layers, channels, paths window

- Text (kerning, leading, tracking baseline shift)
In-Class Photoshop Exercise - 5 points
Create a 1920x1080-sized TV graphic that promotes a show or event, or has some specific purpose. Be sure to use the following criteria:
- Use only a few colors from a single palette selected from W3 Schools or Color Hunt. Most eye-catching graphics use only a few colors that work well together. You can come up with variations on a color by varying the amount of saturation and brightness.
- Use only shapes (circles, squares, etc.) and at least two separate text elements.
- Follow the technical guidelines in Jim's Graphic Tips. Can you put the principles of CRAP to work? (Contrast, Repetition, Alignment, Proximity)
- Turn in a full-size JPEG copy of your graphic (JPG) and the original (PSD) via Canvas. Be sure to save both files named as your username. (I.E. jarkraus.psd & jarkraus.jpg)
Past examples: 1st_PS_graphic (zipped folder of jpegs)
A note about working with layers and saving copies- Always keep your original layers intact. You may need to manipulate these later & make changes. You can flatten copies for display or distribution.
Optional exercises:
If you are unfamiliar with Photoshop, work through some optional exercises. There are excellent tutorials on Lynda.com. There is a tour of the interface in the Adobe Photoshop CC Help PDF. There is also a good tour in the "help" section. If you have PS Classroom in a Book, work through Tour and Working with Selections tutorial. Layer Basics is also a good introductory exercise.
Lab 1 Vocabulary Words (know these) -----------------------------------------
- Anti-aliasing You can turn this feature on and off. It produces intermediately shaded pixels to smooth out the appearance of jagged edges
- Bitmap & vector graphics
- CMYK (subtractive) color mode
- Kerning Adjustment of the space between a pair of letters on the same line. Proportional fonts typically "auto kern". In this manner a small letter o can be tucked under the top of the capital letter T (To). Most design programs let you adjust the kerning between two characters by positioning the cursor between them and then holding down the option key while pressing the left/right arrow key.
- Leading the space between different lines of text
- RGB (additive) color mode
- Sans-serif typeface
- Serif typeface
- Tracking - similar to kerning in that it is a control of horizontal spacing. However tracking controls the spacing of a entire line of text, not just a pair of characters.
Homework (due by the start of Thursday's lab):
- Burrows & Wood reading (Chapter 10 PDF file)
- Graphic Analysis: In this exercise you will find and describe and analyze 2 graphics that are used in TV commercials, titles, segues or promos.
- Scan a commercial TV stream (Network, Netflix, Youtube, etc.) and find two examples of graphics that you find pleasing. One should contain simple elements while the other should be complex. The graphics must be formatted for TV/film (widescreen and not a banner ad). Using screen capture software, a digital camera, or your phone, grab screenshots of the two different graphics.
- In a single document (E.g. Word), write a few paragraphs analyzing each graphic. Include your JPEG or PNG screen captures. Consider the following: What was its purpose? What colors were used? What can you say in terms of composition, texture, contrast, font selection, foreground or background elements? Were they effective? Were they pleasing to you? Why or why not?
- NOTE: Please turn in your homework to the proper Canvas assignment in the form of a Word doc, docx, rtf, or PDF.
