What is a DNG file?

DNG (Digital Negative) is a raw image format standard developed by Adobe, aiming to provide a unified, open, and long-term preservation format for RAW images. It has been adopted by multiple camera manufacturers and is widely used in professional photography. Compared to traditional proprietary RAW formats, DNG offers higher compatibility and better long-term preservation.

DNG files support lossless compression and embedded metadata, ensuring image quality and integrity. They also support various color depths (such as 12-bit or 14-bit), making them suitable for high-quality image processing. Recommended editors include Adobe Lightroom and Adobe Camera Raw, which provide powerful image processing tools and full support for DNG files.

DNG is the preferred format for many camera manufacturers and photographers due to its superior image quality, broad compatibility, and long-term preservation advantages.

What is a PNG file?

PNG (Portable Network Graphics) is a lossless compression image format widely used for web, image processing, and images with transparent backgrounds. It supports 24-bit color depth and alpha channel transparency, ensuring high-quality images across different devices and platforms. Compared to traditional formats like JPEG, PNG offers higher image quality and richer color representation, making it ideal for saving complex graphics, icons, and screenshots. Additionally, PNG files often include metadata (such as author information, copyright information, etc.), facilitating management and search.

PNG was designed to replace the GIF format, addressing its patent issues and providing better transparency support and a larger color range. It is widely used in web design, UI/UX design, digital art creation, and various types of projects.
