The RICOH GR IIIx HDF features a Highlight Diffusion Filter (HDF) that diffuses highlights for softer light, creating more expressive images with a sense of depth and emotion.

With the exceptional image quality, flawless point-and-shoot operation, and outstanding portability that the GR series is known for, the RICOH GR IIIx HDF allows the user to instantly engage the built-in HDF with a single action. This special-effect filter diffuses highlight areas and creates a blurred effect along the images edges, making it possible to capture somewhat nostalgic images resembling those captured in film photography or vintage movies.

This creative versatility expands the visual boundaries of snapshot photography, giving the user the option to shoot high resolution, high contrast images for accuracy and precision; or softer, more expressive images to create a sense of depth and emotion, depending on their subject or creative intention.
