## Summary description

Half-frame neutral density camera filter SEAGULL SB506 in 55mm thread size. This gray (neutral) half-density filter reduces light by approximately half across the frame, useful for balancing exposure between bright and dark areas, controlling highlights, and achieving longer shutter speeds in mixed lighting. Fits lenses with 55mm filter thread for landscape and portrait photography.

## Long description

The SEAGULL SB506 55mm Half-Frame Neutral Density Filter is a gray, half-stop filter designed for lenses with a 55mm filter thread. It provides a gradual reduction of light across part of the frame, allowing photographers to balance exposure between bright and dark areas without affecting the entire image. The filter is intended for situations where a subtle dimming of highlights or a small extension of shutter speed is needed while preserving natural color rendering thanks to its neutral gray tint.
Advantages
This half-frame neutral density filter reduces incoming light by approximately half in the treated area, enabling more precise control of exposure in scenes with contrasting brightness. Its neutral color maintains accurate color balance and avoids color casts. The 55mm screw mount ensures compatibility with lenses using the common 55mm filter thread, and the half-frame design offers targeted adjustment of highlights while leaving other parts of the image unaffected.
Suitable for
 Landscape photography with bright skies and darker foregrounds
 Portraits where background highlights need attenuation
 Cityscapes and architectural shots with uneven lighting
 Long-exposure attempts in mixed lighting where small shutter speed changes are required
Key specifications
 Filter type: half-frame neutral density (half-stop attenuation)
 Thread size: 55 mm
 Color: neutral gray with minimal color cast
 Effect: reduces light by approximately 1/2 (half-stop) across part of the frame
 Application: screw-in mount for standard 55mm lens filters
How to use
Screw the SEAGULL SB506 filter onto the front of a lens with a 55mm thread until it is secure but not overly tightened. Position the darker half of the filter over the brighter portion of the scene, such as the sky, to reduce highlights while keeping the foreground exposure intact. Compose and meter the scene as usual; when necessary, adjust exposure settings to account for the reduced light in the filtered area. For careful alignment, use live view or a tilted viewfinder to confirm the transition line between dark and clear areas falls where intended.
Usage recommendations
Use the filter with lenses that have a 55mm thread and avoid stacking multiple filters that may cause vignetting. Clean the filter surface before shooting to prevent dust or smudges from affecting image quality. When photographing scenes with curved horizons or complex lighting transitions, consider slightly rotating or shifting the filter line by tilting the camera to achieve a natural blend.
