- Meeting Info: In Person on Campus – P116
Topic
Raster Vs. Vector and Image Resolution
We will begin by getting to know each other. The professor and each student will be given the opportunity to introduce themselves and share interests and backgrounds. We will review the Class Syllabus and expectations for students. We will have a Question and answer period.
Today, we will discuss the characteristics of Raster and Vector Files. The best use and best practices associated with them will also be discussed. File Formats, File Naming Conventions, and File Extensions will also be reviewed. We will begin to familiarize ourselves with Image Resolution.
Objectives
What you can expect to learn
- Raster vs. Vector
- Understanding Resolution
- File Formats, Extensions, and File Naming Conventions
Critique
Each week we will review homework assignments from the previous class. Students will participate in reviewing material and offering suggestions for improvement for their cohort.
Lab
Lab assignments are done during class time. This week we will find examples of two Vector and two Raster Files (one in black and white and one in color for each format) to be shared with the class.
Discussion:
Each week you will need to respond to two questions posted. This is a requirement for the participation part of your grade.
Homework Due Next Class:
All work should be submitted by 5:00 pm Tuesday before the next class.
Each file should be saved according to the following naming convention. i.e., 01_LastName.doc (Microsoft Word).
- Read Raster vs. Vector in the Resources and familiarize yourself with each element’s differences. Also, read File Format and Understanding Resolution notes to familiarize yourself with them.
- Write a 200-word description of why you chose them for Vector/Raster format. For example, the description for “Vector” choices may include items from Raster vs. Vector” notes. The same applies to “Raster” choices.” Talk about their file format and extensions. File name: 1162_01_Lastname.doc
Vocabulary
Pixel, Bitmap, File Extensions, File Naming Conventions
Resources
Here are some notes that you should read to educate yourself in the topic area described above.
Reading and understanding both Vector & Raster, I would prefer Vector. While yes, it is extremely easy to convert “all images from digital cameras that is raster” (Referenced in VectorRasterNotes) to a pc, I feel as the praticality of Vector Graphics is better. For one, you don’t have to worry about Scaling due to there being no bitmaps but a thing called paths. Meaning that no matter how big you scale a Vector file, it will always remain the same without getting blurry. While Raster may be cheaper overall, I believe that having a smaller file size and having access to 3 very powerful File Formats helps it more than a Raster. I believe .AI files are simply more advanced due to it having “support for linked and embedded images” and “support for layers and transparency” really helps round out the format because of how much you can simply put into one file. Things such as Raster, is very much resolution dependent meaning you are simply having to figure out how far you can go before it becomes a blurry state. I think what helps both is that they have access to both PDF & EPS which can contain both Raster and Vector while being universal meaning anyone can open it on any device practically.
