Product Information

Full details

The Urth Infrared (R72) Lens Filter Plus+ is designed for photographers seeking to create unique, artistic infrared images. Its key benefit is enabling infrared photography by blocking all visible light, allowing only infrared light (above 720nm) to reach the sensor, resulting in surreal landscapes and dreamlike visuals. A significant caveat is its incompatibility with cameras featuring an internal IR blocking filter. This guide will help you understand its features, application, and care.

Extended Product Information

FAQs

What does R72 mean?

R72 indicates that the filter blocks visible light below 700 nanometers (nm) and allows infrared light above 720nm to pass through.

Can I use this filter for regular photography?

No, this filter is specifically designed for infrared photography. Using it for regular visible light photography will result in black or near-black images because it blocks all visible light.

How do I know if my camera is compatible?

Most modern DSLRs and mirrorless cameras have an internal IR-blocking filter. Cameras that are compatible typically have this filter removed or are older models known for IR sensitivity. Research your specific camera model's compatibility with IR filters.

What kind of post-processing is needed?

Infrared images often require significant post-processing. This typically includes adjusting white balance, channel swapping (e.g., swapping red and blue channels for a 'false color' effect), contrast adjustments, and noise reduction.

Does the filter affect image sharpness?

The filter is made with high-quality, nano-coated glass designed for clarity and exceptional light transmission within the infrared spectrum, minimizing impact on sharpness.

What is the filter made of?

The filter is constructed from tough magnalium for the frame and features 20-layer nano-coated IR72 glass.

What is the warranty on this filter?

The Urth Infrared (R72) Lens Filter Plus+ is backed by Urth's lifetime quality guarantee.

Troubleshooting

Camera does not capture IR effect / image looks normal

Your camera likely has a strong internal IR-blocking filter. This filter is not compatible with such cameras. Consider using a camera specifically modified for IR photography or one known to be IR sensitive.

Severe vignetting (dark corners) on images

The ultra-slim rim design minimizes vignetting, but it can still occur on very wide-angle lenses. Try using a slightly longer focal length or cropping the image in post-processing.

Difficulty achieving proper exposure

Infrared photography requires significant light blockage. Use manual mode, increase ISO, and lengthen shutter speed. Shoot in bright daylight and bracket your exposures if unsure.

Focusing inaccuracies

Some cameras may struggle to focus accurately with IR filters. Try manual focusing or use your camera's live view for precise focusing before the shot.

Filter arrived with visible scratches

Contact Urth customer support immediately. The product is covered by a lifetime warranty for quality issues.

Setup, Compatibility & Care

Setup:

Ensure your camera is compatible with IR photography (i.e., it does not have a strong internal IR-blocking filter).
Screw the Urth Infrared (R72) Lens Filter Plus+ onto the front of your lens, matching the thread size.
Set your camera to manual mode and adjust exposure settings (aperture, shutter speed, ISO) as needed. Due to the filter blocking visible light, you will likely need longer exposure times or higher ISO.
Focus manually or use autofocus if your camera allows with the filter attached, then recompose if necessary.
Capture your image and review in-camera or on a computer, anticipating post-processing.

Compatibility:

This filter is not compatible with cameras that have a built-in IR-blocking filter that is too strong.
Available in various thread sizes (e.g., 39mm, 43mm, 52mm, 55mm, 62mm, 67mm, 77mm, 86mm) to fit different lenses. Ensure you select the correct size for your lens.

Care:

Clean the filter gently using a soft lens brush to remove dust.
For smudges or fingerprints, use a microfiber lens cloth, preferably with a small amount of lens cleaning solution applied to the cloth, not directly to the filter.
Store the filter in its protective case when not in use to prevent scratches and damage.
Avoid exposing the filter to extreme temperatures or moisture for extended periods.
