Gray Card and White Balance Set 2-in-1 by JJC SB2417 — 18% Gray + White Balance, 20×25 cm

The JJC Gray Card and White Balance Set 2-in-1 SB2417 is a compact calibration tool combining an 18% gray reference and a white balance card in one flat panel measuring 20×25 cm. It provides a neutral surface for accurate exposure metering, tonal reference, and consistent white balance in-camera or during post-processing. The reversible or dual-sided design lets photographers and videographers capture a neutral reference quickly on set, in studio sessions, or outdoors to ensure reliable color and exposure across different lighting conditions.

Advantages

The combined 18% gray and white balance surfaces simplify workflow by offering both exposure and color reference without the need for multiple targets. Its 20×25 cm size is large enough to fill the frame at common focal lengths yet compact for inclusion in camera bags. The neutral, non-reflective finish reduces glare and provides predictable results under mixed lighting. The set supports consistent color correction in RAW conversion and video grading, improving repeatability between shoots and across multiple cameras.

Suitable for

• Studio portrait and product photography
• On-location shoots where quick in-camera calibration is needed
• Landscape and travel photography requiring reliable exposure reference
• Video production and color grading workflows

Key specifications

• Two functional surfaces: 18% gray reference and white balance surface
• Panel dimensions: 20 × 25 cm
• Neutral, non-reflective finish for accurate metering and color sampling
• Lightweight, flat design suitable for handheld positioning or mounting

How to use

Place the panel in the scene illuminated by the same light that falls on your subject. Fill the frame or a representative portion of the frame with the gray surface to set exposure or use the white surface to establish white balance in camera or to create a custom white balance preset. When shooting RAW, record a reference frame with the card visible for later color correction; in video workflows, capture a short clip of the card for grading. After capture, sample the card area in your editing software to apply exposure and color corrections consistently across images or footage.

Usage recommendations

For best results, position the card so it receives the same light as the subject and avoid direct reflections. When working in mixed lighting, record separate references for each dominant light source. Store the panel flat or in a protective sleeve to prevent creases or contamination of the neutral surface.
