Casting in Post-Production
Change the model.
Keep the photo.
We enable fashion & apparel teams to change the model on an existing campaign photo — without a reshoot. Done for you, or done by you.
The problem
Creative fatigue is real.
And your options are limited.
You invest in a shoot. It performs, then it fatigues, like every creative does. The moment it dips, you need fresh creative to test.
But fresh creative means new variations, and variations mean production, budget, and time. You just put real money into this shoot, and already you need another one just to keep testing.
You should be able to get more out of what you already shot.
Why Castinger
Do you test
the model?
You test everything else. Headlines, hooks, colors, calls to action, all easy to swap and measure. But the model is the one variable you can't change without booking another shoot. So the biggest lever in the whole image stays frozen.
The eye behind it
Hi, I'm Ákos, founder of Castinger, a photographer and AI engineer. I kept wanting the best models on my campaigns, and I stumbled on face swap technology. But I couldn't find a tool that held up at high resolution for a real shoot, so I experimented for a long time and built my own.

The plan
Here is what you need to do.
Shoot exactly as you do now.
Nothing about your process changes. Real models, real styling, real light, shot at full resolution by real professionals. That shoot is the foundation Castinger builds on.
Vary the model. Keep the shot.
Pick the models that fit your message, and take control of the details that used to be locked in on the day: makeup, hair, ethnicity, facial hair. The whole look becomes yours to direct.
Now you can test the model's identity.
The variable you could never A/B test becomes just another lever. Different regions and audiences respond to different models, so let the data show you which face connects in each market.
Double down on what performs.
When you know which model wins, one shoot has become a scalable creative engine, and creative fatigue stops setting the pace.
The tool
All you need is your browser.
No software to install, no setup, no struggle. Open your shoot, vary the model, fine-tune the result, and export. A few simple steps, start to finish.

What's at stake
More variations shouldn't cost you
the trust you built.
Creative fatigue doesn't let up. The demand for fresh content and new variations has never been higher, because testing is the only way to learn what your audience actually responds to.
To keep up you have two familiar options, and neither is good. Pour money into more production, which is slow and expensive. Or generate images with AI, and risk the fake, generic look people are already tired of. Reach for a tool you can't control, and one bad image can erode the brand reputation you spent years building.
We believe there's a middle ground, one where you stay in control. Castinger starts from your real photograph and changes only what you choose. The garment, the fabric, the light, the detail stay exactly as you shot them. It was built to edit real photography, not replace it, and that's still the only rule.

What you get
Test every look you couldn't before.
Stay unmistakably you.
One shoot stops being one image. Try a different face, a fresh look, a model that speaks to a different market, all from the photo you already paid for. No reshoot, nothing locked to a single version. You decide what changes and what stays.
And everything your audience sees is still real. Your photography, your quality, your brand, with the freedom to try every direction without ever looking like AI made it. You get to move, and the brand stays yours.
