Want to remove a distracting object from your photo, enhance a specific detail, or add something new—without regenerating the entire image? With LTX’s Brush tool, you can make precise adjustments to any image, all while maintaining the integrity of the original look.

For designers, marketers, agencies, and creators, even the smallest visual inconsistency can disrupt a polished result. Traditionally, fixing these issues required complex image-editing tools or regenerating the whole image, which often produced unpredictable results.

Now, with Brush, small targeted edits are fast, intuitive, and precise. In this article, we’ll walk you through how to refine or update a specific part of your image step-by-step—whether you're removing unwanted objects, enhancing product details, or adding missing elements.

Why Make Targeted Edits to Images?

Image creation workflows often break down when a single small detail needs to be fixed. You might love the shot—but notice a distracting sign in the background, a misplaced shadow, or a product detail that needs adjustment. Full regeneration can change the entire image, forcing teams to continuously redo work and hope for a similar output.

Creators need speed and consistency. A tiny visual issue shouldn’t require starting over.

Historically, precise edits demanded advanced tools or manual retouching skills. Even fixing a corner of an image could take significant time and technical proficiency. The Brush feature replaces those workflows with a simple, intuitive interface that lets you update only the area you want—no complicated masking, layering, or full-image regeneration.

LTX’s Brush gives teams the precision and control they need:

• Remove distractions without affecting the rest of the image
• Add or refine details while keeping the original style
• Adjust specific areas quickly, with no editing expertise required

How to Edit Part of an Image: A Step-by-Step Guide

LTX makes targeted image edits simple and intuitive. Here are two ways to start using the Brush tool:

Once you finish brushing, you’ll be taken back to the prompt box.

Step 5: Click Generate

Press Generate to apply the update and instantly receive the updated version of your image.

‍Pro Tips for Cleaner Object Removal

While LTX’s remove object function is designed to deliver professional-quality results with minimal effort, applying these tips will ensure even better outcomes:

• Use Precise Selection: For detailed edits, zoom in on the object you’re removing to achieve precision and avoid unintended distortions.
• Blend Edits with Surroundings: When adding or replacing elements, reference nearby textures, lighting, or colors in your prompt to help the AI blend the update naturally into the image.
• Avoid Overloading the Prompt: Keep the prompt focused on one action at a time. Too many instructions can cause mixed or inconsistent outputs.

The Benefits of AI-Powered Precision Editing

AI-powered editing using the Brush tool reshapes how creators work with images. Instead of regenerating entire visuals or learning complex software, teams can update only the parts that matter.

Here’s how it transforms your workflow:

Efficiency & Time Savings

What used to require full-image re-renders—or even external editing tools, now takes seconds. Make changes instantly without disrupting the rest of your composition.

Cost-Effectiveness

Eliminate the need for multiple apps or professional retouching support. Brush offers professional-grade editing at no additional cost and across all pricing tiers.

Professional Results with Minimal Effort

Whether you’re part of an agency, an in-house creative team, or a solo designer, LTX’s Brush tool gives you unmatched control over your visuals. Instead of rebuilding entire images or compromising on quality, you can refine only what needs improvement—quickly, accurately, and intuitively.
