Sony Alpha RAW
The raw format powering the mirrorless revolution.
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.
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.
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.
PNG-24 (24-bit RGB)
The standard for opaque, true-color lossless images on the web.
PNG-24 is the standard version of the PNG format for opaque, full-color images. It supports 24-bit color depth, which allows for over 16 million distinct colors (True Color)—the same color range as a standard JPEG. Unlike JPEG, however, PNG-24 uses lossless compression. This means it preserves every single pixel exactly as it was created, with absolutely no blurring or artifacts. This makes PNG-24 the ideal choice for complex graphics, screenshots, and detailed diagrams where quality is paramount and transparency is not needed. Note that while 'PNG-24' is often used to refer to any true-color PNG, strictly speaking, it refers to the RGB variant without an alpha channel. If you need transparency, you are technically using PNG-32 (RGB + Alpha).
A PNG-24 image consists of three color channels: Red, Green, and Blue. Each channel uses 8 bits of data per pixel, resulting in 24 bits total (8+8+8). This allows for 256 levels of intensity for each primary color, combining to produce 16,777,216 possible colors. Because it lacks an alpha channel, every pixel in a PNG-24 file is fully opaque. While the PNG specification allows for a 'tRNS' chunk to define a single specific color as transparent (similar to GIF), this is rarely used in modern web design in favor of the full alpha transparency found in PNG-32.
PNG-24 was part of the original PNG 1.0 specification released in 1996. It was designed as a direct, patent-free competitor to JPEG for lossless image storage. While JPEG won the war for photographs due to its superior compression ratios, PNG-24 became the standard for screenshots, diagrams, and digital art where preserving exact pixel values was more important than file size.
