Why paper weights, reflection factors, and color matching are critical when filming currency stacks up close in high resolutions.
Filming in 4K, 8K, and IMAX means every fiber on set is scrutinized. Prop money that looks fine from 10 meters away will look like cardstock paper once you cut to a medium close-up of a suitcase transaction.
Here is the technical guide to selecting prop bills that fool modern sensors.
The Problem with Digital Camera Glare
Regular printer paper is coated in wood-pulp sizing agents that reflect standard LED studio tubes. When high-power key lights hit cheap props, they create a 'hot spot' of high-glare white light, rendering the banknote design unreadable.
To bypass this, professional prop bills are coated in a **micro-rough anti-reflection coating**. This disperses incoming light in multiple directions, maintaining the vivid green, red, or gold tones of Canadian notes even under high key lighting.
Polymer Feel & Texture Modeling
Canadian banknotes feel unique because they are manufactured out of a specialized polypropylene plastic polymer. While you cannot legally print props on actual polymer, you should use **long-fiber synthetic compound bills** of correct weights (approx. 90-100 GSM). They possess the correct slip coefficient, allowing actors to count them quickly on camera without sticking.
Denomination Advice for Color Correction
* **Spruce Green ($20)**: Highly forgiving under cool-toned and ambient neon lighting. Great overall stack filler.
* **Gold Ochre ($100)**: Prone to yellow-channel saturation under warm tungsten lighting. Always ensure your DPs adjust white balance to prevent prop gold from looking orange.
* **Crimson ($50)**: Ideal for high contrast. Pops dramatically in dark briefcases against dark leather lining.
