How do I use AI product photography for clear plastic or liquid-filled products?

Quick Answer

Clear plastics and liquids are the hardest materials for AI because of light refraction. The best approach is to use an AI tool that lets you reuse a specific lighting setup as a saved Photography Style and lock liquid color with a precise hex value. Nightjar is designed to handle these transparency challenges by analyzing the edges of the product and filling the background through the clear material, rather than treating it as an opaque block.

Why Transparency Fails in Generic AI

When you place a transparent bottle on a new background using standard AI tools, the tool often fails to update the pixels inside the bottle to match the new background. The result looks like a cutout sticker pasted on a photo.

Accurate Rendering Techniques

To achieve photorealism with clear products:

• Lighting is physics. The light must pass through the product. Pick a Photography Style with backlit or golden-hour direction so the model is told to calculate light passing through the object.
• Liquid color. If you sell a beverage or skincare oil, the color must match the bottle. Use the Recolor Edit Shortcut to set the exact hex code of your liquid. Shadows, folds, and material properties are preserved while the fluid color is updated.
• Edge definition. Clear plastic disappears against similar backgrounds. Choose a Photography Style with high-contrast or studio lighting so the AI defines the edges of the bottle with specular highlights.

The Advantage of Consistent Styles

If you have a full line of clear skincare bottles, you do not want the lighting to change in every shot.

• Upload one strong reference shot of a clear bottle.
• Create a custom Photography Style from that reference so Nightjar captures how the light hits the glass.
• Apply that Photography Style across your catalog so every clear bottle looks like it was shot in the same studio session.
