3.5 – Image Editing with Editor Lesson

Lesson Overview

This lesson introduces the Midjourney Editor, providing a hands-on way to modify images after initial creation. With the Editor, you can interact directly with your image by erasing specific elements, restoring areas you decide to keep, and using inpainting to seamlessly add new objects. Tools like scaling and aspect ratio adjustment make it easy to adapt artwork to different needs—whether you want a wider frame or need space for additional content.

The Editor is designed for flexibility. It solves the challenge of making precise, spot changes without starting anew or affecting the whole image. For example, you might want to add sunglasses to a character, change the background, or extend the canvas for a new composition. By combining brush controls, undo/redo functions, and the ability to update your prompt, you have the freedom to experiment with creative ideas while saving time.

These skills are helpful for anyone working with AI-generated imagery who needs more control over results. Using this editing tool, creators can quickly refine or iterate on images in a wide variety of real-world scenarios, from marketing visuals to artwork refinements.

Who This Is For

If you’re looking for more control over your Midjourney images, this lesson will be especially helpful. It’s useful for:

• Digital artists refining AI-generated artwork or prototypes
• Marketers adjusting images for specific campaigns or ads
• Content creators who need customized visuals for presentations or online content
• Teachers or educators preparing unique graphics for lessons and handouts
• Product designers iterating on concepts and mood boards
• Anyone wanting to edit or expand Midjourney images easily without external image tools

Where This Fits in a Workflow

Editing images with the Midjourney Editor is typically done after you generate your initial artwork. Once you have a base image, the Editor allows you to make targeted changes quickly without starting the generation process over. For example, you might want to erase an object, reposition key elements, or extend your artwork’s dimensions to fit a presentation slide or social post.

This lesson’s methods come in handy when you need to personalize an image to fit a project brief, adjust for print and web formats (such as moving from square to wide layouts), or simply enhance particular details after reviewing an image. Overall, it streamlines creative workflows by enabling iterative edits right within Midjourney.

Technical & Workflow Benefits

Previously, making even minor adjustments—like removing an element or modifying a detail—meant re-typing prompts and regenerating images from scratch. This workflow is slow and depends on chance for specific results. The Editor provides instant, brush-based editing with undo, redo, and selective erasure, allowing you to guide changes exactly where needed.

For instance, an artist can erase a section to replace with new content, scale the image for a different format, or touch up images for an ad—all without leaving the Midjourney interface or dealing with outside editing software. The ability to restore erasures and reset to the original image cuts down on risk and makes experimentation easier. This approach saves time, supports consistent image quality, and allows for multiple rapid iterations—valuable for tight deadlines or fast-moving projects.

Practice Exercise

Try out the Midjourney Editor with a sample image using these steps:

1. Generate an image, such as “an oil painting of a royal queen sitting on a decorative chair in a throne room.”
2. Open the Editor from the “More” menu. Use the erase tool to remove an area—for example, a section of the queen’s face—then adjust the prompt to add something new (like “wearing sunglasses”).
3. After submitting changes and viewing the result, repeat the process. Adjust the aspect ratio to 4:3 and extend the image’s background. Use the brush to erase or refine areas, update the prompt again (for example, “large brightly colored flowers in a vase on a table next to her”), and observe the outcome.

Reflection: Compare this hands-on editing approach to starting from scratch with new prompts. How does the Editor improve your ability to fine-tune and iterate on your images?

Course Context Recap

This lesson builds on earlier Midjourney editing techniques like remixing, creating variations, panning, and upscaling. By learning to use the Editor, you now have a set of tools for direct, detailed changes—opening up even more creative possibilities. Next, you’ll discover how to continue refining and finalizing your images as the course moves forward.
