Fresh drop from r/PromptEngineering: u/robert-988 built getdeconstruct.com, a tool that takes a reference image and turns it into a Midjourney v6 prompt. The twist is what it pulls out. It doesn’t just describe the subject. It breaks the photo down into lighting, camera, styling, and aspect ratio flags.
What’s new
The demo is a dual-lighting editorial portrait. The tool read the image and wrote a v6 prompt for it. You upload a photo you like, and you get descriptors you can paste straight into Midjourney. New accounts get 10 free credits, so you can try it on your own images.
The twist
Most image-to-prompt tools stop at “woman, studio, dramatic.” This one goes after the lighting setup. One commenter said it picks up the key light versus the rim light well without overcomplicating the prompt. That’s the hard part to describe by hand. Lighting is usually why a reference photo looks expensive, and it’s the first thing people leave out of their prompts.
To be straight with you, I haven’t run it myself. The author is asking the community whether the breakdowns are accurate, and the thread is small (2 upvotes at the time of writing). So treat it as a promising early build, not a proven one.
Mini-workflow to test it
- 📸 Pick a reference photo with obvious lighting, like a two-color split or a strong rim light.
- 🧩 Upload it at getdeconstruct.com and spend a credit.
- 🔍 Read the output and check each piece: Is the key light on the right side? Is the camera and lens feel close? Is the aspect ratio flag right?
- 🎯 Paste it into Midjourney v6 and generate a few runs.
- ⚖️ Put your results next to the original. If the light direction survived, the breakdown is doing its job.
Pro tips
- Test on a photo where you already know the lighting. Then you can grade the tool instead of trusting it.
- Try a harder image too. A commenter wondered how it handles environmental light sources, and that’s where I’d poke it first. Window light, neon signs, or mixed color temperatures will show you the limits quickly.
- Treat the output as a first draft. Keep the lighting and camera lines, then swap in your own subject and styling.
Call to action
Try it on one of your own reference shots and tell the author what you’d tweak. They asked for feedback, and the early users shape the tool. If you do run it, drop your result in the comments so we can see how it holds up.
