How to Mask Transparent Objects Like Glass and Plastic

Cut out bottles, jars, and clear packaging while keeping the see-through quality that makes them look real.

Why Transparent Products Are Hard

A standard mask treats every pixel as either in or out. That breaks the moment you try it on a perfume bottle or a water glass: either the transparent middle goes opaque, or the highlight edges vanish. Neither looks like the real product.

Retouchable uses transparency-aware extraction. It keeps the alpha channel graded across the glass so light can still pass through, and it preserves the bright specular edges that sell the material as clear.

How It Works with Retouchable

Upload Your Glass Product Shot

Start with a clean, well-lit photo of your bottle, jar, or clear container.

Enable Transparent Extraction

Retouchable detects transparency automatically and generates a graded alpha mask.

Place on a New Background

Drop the cutout onto any scene. The background shows through the glass naturally.

5 Tips for Masking Glass

Use a Gradient Backdrop

A smooth white-to-grey gradient reveals the shape of the bottle through highlights and shadow lines, giving the AI more to work with than a flat white wall.

Light the Edges, Not the Face

Strip boxes placed left and right create the bright specular lines that define glass. Front lighting just bounces off and washes out the form.

Shoot on a Sheet of Glass

Placing the product on a clear riser lets you light from below and avoid the ugly surface contact line that breaks transparency illusions.

Avoid Reflective Surroundings

Anything shiny near the bottle will reflect in the glass and end up inside your mask. Black flags on both sides keep reflections controlled.

Composite Onto a Contrasting Scene

A clear bottle needs something behind it to show it is transparent. Always drop it onto a scene with some color or texture so the effect reads.

Clear Products, Clean Cuts

Extract bottles and glass without losing what makes them transparent.

Why Retouchable for Compositing

Transparency-Aware Extraction

Alpha values are graded across glass surfaces so the background still shows through.

Specular Edge Preservation

Bright highlight lines on bottle edges are kept intact during masking.

Refraction Handling

Retouchable keeps subtle bending of light through the glass so the product looks physically real.

Label Detail Retention

Printed labels on transparent bottles stay sharp and readable after the cut.

Frequently Asked Questions

Can I see the new background through the glass after masking?

Yes. Transparency-aware extraction keeps the alpha graded so anything behind the bottle shows through.

Does this work on frosted or textured plastic?

Yes. The model handles frosted glass, textured plastic, and other semi-transparent materials.

Will the bottle label still look sharp?

Yes. Labels are treated as opaque regions and retain full detail.

Is there a specific lighting style I should use?

Edge lighting with strip boxes gives the best results for transparent products.
