GRA-220 is SNHU's Introduction to Digital Imaging, a three-credit course with no listed prerequisites.
The catalog describes it as using Photoshop and Illustrator for professional computer graphics creation, with the software and hardware typically used in graphic design, video, photography and interactive web or multimedia industries.
Emphasis is placed on image-capturing devices such as scanners, digital still cameras and video cameras. Image editing and color management systems are discussed and demonstrated, and the course defines the differences between vector and bitmap graphics.
The challenge is breadth. You must handle capture, editing, color and output, and know why settings differ between print, broadcast and web.

Key Concepts Explained
Vector and Bitmap
Bitmap images are grids of pixels; vector graphics are shapes defined by maths. Use bitmaps for photographs and vectors for logos and line art.
Example: Enlarge a bitmap too far and edges turn blocky. Enlarge a vector and the edges stay sharp. That is why a logo is usually kept as a vector file.
Preparing for Different Outputs
Print needs higher resolution and often a different color mode than web. Check the target before you export, and keep an editable master.
Layers, Masks and Non-Destructive Editing
Layers hold separate elements. Masks hide or reveal parts without erasing pixels. Working this way keeps changes reversible.
Output Checklist
| Output | Check |
|---|---|
| Resolution, color mode, bleed | |
| Web | Pixel size, file size, format |
| Video or broadcast | Frame size and safe areas |
Typical Assignments and How to Approach Them
The catalog says students are encouraged to experiment with their own and pre-existing images. Check your course page for the actual tasks; these types are common.
| Task type | What it tests | How to approach it |
|---|---|---|
| Photo editing exercises | Technique | Work on duplicate layers and save versions |
| Montage or composite | Layering and masking | Match light and color between elements |
| Vector illustration | Illustrator skills | Use few anchor points and clean paths |
| Copyright or process write-up | Awareness | State where images came from and what rights apply |
A Non-Destructive Editing Workflow
Image editing assignments reward careful workflow. Following the same order each time helps you avoid errors and explain your steps.
| Step | Action | Why |
|---|---|---|
| 1 | Duplicate the original and work on the copy | Keeps the source safe |
| 2 | Crop and straighten | Sets composition early |
| 3 | Correct tone and color with adjustment layers | Keeps changes reversible |
| 4 | Retouch on separate layers | Allows selective undo |
| 5 | Sharpen last for the intended output | Output size affects sharpening |
Record settings as you go, such as the color profile and resolution. If the assignment asks you to explain your process, these notes are your evidence.
Example: When building a montage, match the light direction and color temperature of each element, add soft shadows on a separate layer, and use masks instead of erasing. Then explain in two sentences why masks keep the edit flexible.
Where Students Get Stuck
- Destructive edits. Use layers and masks.
- Color mismatches. Keep one color setup throughout.
- Wrong export settings. Check output requirements first.
- Image sources. Use images you own, created or licensed, and record the source.
Reading the Rubric for an Imaging Project
Imaging assignments combine technical accuracy with creativity. Review your work against these criteria and your course page.
| Typical criterion | How to meet it |
|---|---|
| Technique | Correct use of layers, masks and adjustments |
| Color management | Consistent color and appropriate mode |
| Output | File prepared for the stated medium |
| Creativity | Experimentation with images |
| Copyright awareness | Sources recorded and rights respected |
Keep a short source list for every image you use. It answers the copyright question and protects you if an instructor asks where something came from.
A Four-Step Pacing Plan
Spread an imaging project over four short steps instead of one long push. The plan below works whether you have a week or a month, and you can scale the steps to your deadline.
| Step | Focus |
|---|---|
| 1 | Gather and organize source images |
| 2 | Edit non-destructively |
| 3 | Prepare outputs |
| 4 | Document process and sources |
Leave a day between the last two steps if you can. Reading your own work after a break is the easiest way to spot gaps in logic, missing citations and instructions you forgot.
Study Tips for GRA-220
- Practice one technique at a time with your own photos.
- Keep an organized folder with originals and edits.
- Note settings you use so you can explain them.
- Compare your result with the original before submitting.
