Basic Editing: Changing Clothes and Colors
Start Simple: Change Shirt Color
Why this matters for business: For YouTube thumbnails, you can A/B test three versions against each other—red, blue, green—without doing multiple photoshoots.
Change the Actual Clothing
Prompt: "Change the shirt to a fitted black Prada blazer"The AI will:
Follow-up: "Remove Prada logo from the blazer" (to avoid trademark issues)

Removing and Adding Objects
Remove Objects Instantly
Prompt: "Remove the flowers in the background"The AI cleanly removes specified elements while maintaining image coherence.
Change Backgrounds
Prompt: "Change the background to bright red with a slight gradient"More dramatic: "Change the scenery in the background to a Harry Potter style library"

Editing Styles and Thumbnails
YouTube Thumbnail Style
Prompt: "Add a bit of depth, drama, and color vibrance to edit this like a pro YouTuber for a thumbnail"Or more specifically: "Edit this image in the style of Mr. Beast"
Pro tip: If you don't like the output:
Add Text to Thumbnails
You can tell it what words to include, though adding: "Do not add words" gives you a clean base to add text yourself in Canva.Creative Styles
Prompt: "Make this look like a sketch on a journal"The AI can transform your professional photo into completely different artistic styles.

Creating Images from Scratch
You don't need to start with a photo of yourself:Prompt: "A Maine Coon cat wearing gold round glasses sitting by a fireplace"
Follow-ups:
What's remarkable: The cat maintains consistency across different angles and perspectives. Same cat, same glasses, same environment—just different views.

Advanced Technique: Image Blending
Blending combines multiple images into one cohesive creation.Product Photography
Setup:Prompt: "Create an image of the woman on the right holding up the bag of product on the left"
Results:
Business application: Test ads rapidly without expensive photoshoots. If you own a clothing or product company, this is game-changing for A/B testing.

The Tesla Cybertruck Example
Prompt: "Create an image of the woman driving the Cybertruck with the windows down"More specific: "Create an image of this woman driving the Cybertruck on a winding mountain highway at sunset"
While challenging (vehicles are complex), the AI attempts reasonable compositions and gets backgrounds/scenery surprisingly right.

Adding Equipment and Context
Podcast Setup
Prompt: "Add podcast headphones and a microphone to the image"The AI understands:
Follow-up: "Move the microphone to the side and add a boom arm"
Adding Signage
Prompt: "Add 'AI Podcast' sign in the background"Refinement: "Make this sign much bigger"

Pro Tip: When Prompts Don't Work
If the AI isn't giving you what you want, ask ChatGPT for help:> "I have a picture of myself with podcast headphones on. I want an AI tool to add 'AI Podcast' in the background as if it were a 3D sign on the wall behind me. Give me the prompt."
Then copy that prompt into Gemini. The more specific the instructions, the better the results.
Remember: If the AI isn't giving you what you want, we are probably the bottleneck—not the AI.
