About ARW Format

Sony Alpha RAW

The raw format powering the mirrorless revolution.

Overview

ARW is the raw image format used by Sony's Alpha series cameras (like the A7, A6000, and ZV series) and Cyber-shot RX series. As Sony became the dominant player in the mirrorless camera market, ARW became one of the most common raw formats in the world. ARW files contain the raw data from Sony's Exmor sensors. They are known for their malleability, allowing photographers to push shadows and pull highlights to extreme degrees without the image breaking apart.

Technical Details

ARW files are TIFF-based containers. Sony offers three main compression types: 1. **Uncompressed**: Massive files, but guaranteed maximum data integrity. 2. **Compressed (Lossy)**: The default for years. It uses a delta-compression scheme that can occasionally cause 'star eater' artifacts or posterization around high-contrast edges, but saves 50% space. 3. **Lossless Compressed**: Introduced in newer models (A7 IV, A1) to solve the quality issues of lossy compression without the massive size of uncompressed.

History

ARW replaced the older SR2 format. It has gone through several iterations (v2.3, v4.0). The format faced controversy in the past due to its lossy compression algorithm, which led Sony to introduce the Uncompressed and later Lossless Compressed options in response to user demand.

Common Use Cases

  • Portrait Photography: Eye-AF driven portraits.
  • Low Light / Night: High ISO shooting.

Advantages

  • Sensor Data
  • Dynamic Range

Limitations

  • Compression Artifacts (Older Models)
  • Large Files

About JNG Format

JPEG Network Graphics

JPEG compression with PNG transparency.

Overview

JNG (JPEG Network Graphics) is a sub-format of the MNG animation format. It was designed to combine the high compression of JPEG with the alpha transparency features of PNG, something that standard JPEG lacks. It essentially wraps a JPEG stream and a mask channel in a chunk-based container.

Technical Details

A JNG file structure mimics PNG. It uses a 8-byte signature and chunks. The image data is split into a color chunk (JDAT) which contains JPEG data, and an alpha chunk (IDAT) which contains PNG-compressed alpha mask. This allows for 'lossy color, lossless alpha' images, which is very space-efficient for photographic sprites.

History

Created by the PNG Development Group around 2001 as part of the MNG (Multiple-image Network Graphics) project. It failed to gain traction as MNG was rejected by Mozilla and Chromium in favor of APNG and later WebP.

Common Use Cases

  • Historical Web Design: Used briefly in the early 2000s for transparent photos.

Advantages

  • Lossy + Alpha

Limitations

  • Obsolete
