Hey fam, it’s Prayertitus here—founder of PromptLoaded.com, your favorite spot for prompt engineering and AI creativity. I recently stumbled on a wild technique that lets you turn any photo into a realistic ballpoint pen sketch using Gemini Nano-Banana (yes, that’s the actual name). And trust me, it’s way easier than it sounds.
Let me walk you through how I did it—and how you can too.
📸 Step 1: Pick Your Reference Image
First things first, grab a photo you want to transform. I used one of my own images as a reference. You can use a portrait, a landscape, or even a product shot—just make sure it has good contrast and detail.
🌐 Step 2: Head Over to Google AI Studio
Go to aistudio.google.com. This is where the magic happens. Upload your reference image and get ready to flex some prompt engineering muscle.
💬 Step 3: Ask Gemini for Help
Here’s the trick: type this into the prompt box:
“Give me a prompt to achieve this style.”
Wait a few seconds. Gemini Nano-Banana will analyze your image and spit out a custom prompt designed to recreate that exact sketchy vibe.
🎨 Step 4: Apply the Prompt to Your Image
Now, upload the image you want to stylize (it can be the same one or a different one), paste the prompt Gemini gave you, and hit generate.
Give it a few seconds… and boom 💥—your image is now a ballpoint pen-style sketch. It looks hand-drawn, textured, and super artistic.
