About:
FastRawViewer is a high-performance tool for viewing, culling, and sorting RAW image files directly from digital cameras. It renders images on-the-fly without creating intermediate cache files, ensuring accurate previews of RAW data. The software accelerates the initial selection process by allowing photographers to quickly flag, rate, and reject images before detailed editing.

Key Features:

Instant RAW rendering without caching
Advanced culling and rating tools
Detailed EXIF and metadata overlay
Dual-monitor support for efficient workflow

Use Cases:

Rapidly culling large sets of wedding or event photos
Verifying focus and exposure on RAW files in the field
Sorting and organizing images before importing to Lightroom

Alternatives:

Adobe Lightroom – Lightroom offers full editing and cataloging but is heavier and slower for simple culling tasks.
Apple Preview – Preview is a basic OS utility that lacks specialized RAW processing speed and metadata tools.
