About ERF Format

Epson RAW

The raw format for the cult classic Epson R-D1.

Overview

ERF is the raw format used by the Epson R-D1, the world's first digital rangefinder camera. Released in 2004, the R-D1 is a cult classic among camera enthusiasts for its analog handling (it even has a film advance lever to cock the shutter). ERF files contain the raw data from the camera's 6-megapixel CCD sensor.

Technical Details

ERF is a TIFF-based raw format. It is relatively simple compared to modern formats, storing 12-bit data.

History

Epson only made one digital camera line (R-D1, R-D1s, R-D1x). The format died with the discontinuation of the R-D1x in 2014.

Common Use Cases

  • •Street Photography: The R-D1 was a street shooter's dream.

Advantages

  • Simplicity

Limitations

  • Rare

About PGX Format

JPEG 2000 VM Uncompressed

A single-component test format for JPEG 2000 verification.

Overview

PGX is an extremely simple, uncompressed raster format created specifically for the development and testing of the JPEG 2000 standard (ISO 15444). It is defined in the JPEG 2000 Verification Model (VM). Its purpose is to store a single component (channel) of an image with potentially high bit depth and signed/unsigned values, without the complexity of a full image container.

Technical Details

A PGX file represents one image channel (grayscale). It starts with a minimalist text header identifying the endianness (`LMS` or `Big`), the sign (`+`/`-`), the bit depth, and dimensions. The raw pixel data follows immediately. It is effectively a raw dump of a single image plane.

History

Developed by the JPEG committee during the creation of JPEG 2000. It allowed researchers to test wavelet compression algorithms on raw data without worrying about file headers or color transforms.

Common Use Cases

  • •Algorithm Testing: Testing a new wavelet transform implementation.
  • •JPEG 2000 Component Separation: Storing the separated Y, U, and V channels of an image before compression.

Advantages

  • Precision

Limitations

  • Grayscale Only
  • Obscure
