CMST 425 at UMGC continues the hands-on study of Adobe Photoshop, applying advanced design concepts, adjustments and batch-processing techniques to create and edit professional images.
UMGC now lists the course as WDDE 425, Advanced Image Editing (formerly CMST 425), with WDDE 325, the renumbered Image Editing course, as the prerequisite. The emphasis is on advanced concepts and practical techniques for print, web and other electronic media, with ethical and legal issues discussed throughout.
Where the first course teaches you the tools, this one expects judgment and efficiency. Instructors look for edits that are convincing, non-destructive and well organized, and for workflows that could handle a professional volume of images.

What CMST 425 Covers
- Advanced design concepts: composition, visual hierarchy and color applied to complex images.
- Advanced adjustments: precise tonal and color control with curves, blend modes and luminosity-based masks.
- Batch processing: actions and automation that apply the same steps to many images.
- Creating and editing images: from concept to completion, including complex composites.
- Output: preparing professional images for print, web and other media.
- Ethical and legal issues: manipulation, disclosure, rights and model releases.
Key Concepts Explained
Actions and Batch Processing
An action records a sequence of steps so Photoshop can repeat them. Combined with File, Automate, Batch (or Image Processor), it applies them to a whole folder, which is how professionals handle large shoots.
Example: A client needs 120 product photos resized to 2000 pixels, sharpened for web, given a watermark and saved as JPEG. Recording one action and running a batch on the folder does in minutes what would take hours by hand, and every image is treated identically.
Advanced Masking
Complex selections such as hair, fur or glass need more than one technique. Channel-based masks, Select and Mask refinement and luminosity masks let adjustments follow detail that a simple selection would miss.
Frequency Separation and Blend Modes
Frequency separation splits an image into texture (high frequency) and color and tone (low frequency) so each can be retouched without damaging the other. Blend modes control how layers interact, for example Soft Light for dodging and burning.
Example: For a portrait, uneven skin tone is smoothed on the low-frequency layer while pores and fine texture stay intact on the high-frequency layer. The result looks retouched but still natural, which is usually what a professional brief asks for.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Advanced composite | Masking, perspective, light matching | Plan light direction and perspective before combining sources |
| Professional retouch | Subtle, non-destructive technique | Work on separate layers so every change can be adjusted |
| Automation task | Actions and batch processing | Test the action on two or three files before the full batch |
| Rationale or ethics response | Professional judgment | Explain why each major change suits the purpose and context |
Professional Ethics and Rights
The course discusses ethical and legal issues alongside technique. At this level that usually means three questions. Is the change honest for the context, such as editorial versus advertising? Do you have the right to use and alter each source image? Would a reasonable viewer be misled in a way that causes harm?
Keeping a short source log (image, origin, license) and noting significant manipulations in your rationale shows the professional judgment the course is looking for.
Preparing Images for Print, Web and Other Media
The description emphasizes professional images for print, web and other electronic media. One master file can serve all three if you keep it layered and high resolution, then export versions with the right color profile, size and format for each use.
Building those exports into an action is a natural way to combine the course's output and automation topics in a single assignment.
Where Students Get Stuck
- Over-retouching. Plastic skin and halos signal heavy-handed edits. Reduce opacity and compare with the original.
- Actions that fail on some files. Different sizes or orientations break recorded steps. Build actions that handle variation or sort files first.
- Disorganised PSDs. Dozens of unnamed layers make review and revision hard.
- Ignoring output. A composite prepared only for screen may not print well.
Study Tips for CMST 425
- Revisit layers, masks and adjustment layers from Image Editing before starting.
- Keep a folder of reusable actions you build during the course.
- Toggle your retouching layers off regularly to check you have not gone too far.
- Study professional before-and-after examples and note what was changed.
