Mastering Photo Formats: Your guide to which storage file types to use

post production tech talk technique Dec 13, 2023

 Stepping into digital photography introduces a myriad of decisions, one of which is selecting the right file format for your images. Each format - JPG, TIF, RAW, DNG, and PNG - has its unique traits affecting image quality, versatility, and size. This guide aims to clarify these common file formats, helping you make informed decisions that elevate your photography.


JPG (JPEG): Compact and Web-friendly

JPEG stands for Joint Photographic Experts Group, a format celebrated for its compact file size. It's ideal for online sharing, using lossy compression that slightly compromises image quality for the sake of reduced size. This compression often goes unnoticed in casual photography, making JPG perfect for social media, email, and web display.


When to Use JPG:

  •  Sharing on social media platforms.
  •  Emailing or using in messaging apps.
  •  Quick loading on websites and blogs.


Be careful when doing repeated open and save operations with a JPG file as the image is compressed every time and can result in the loss of fine detail.


TIF (TIFF): The Professional's Choice

TIFF (Tagged Image File Format) is a favorite among professionals due to its lossless compression. This means no compromise in image quality, making TIFF files large but perfect for high-end printing and photo manipulation. It's the go-to format for quality-driven tasks like professional prints, archives, and extensive editing.


 When to Use TIF:

  •  High-quality printing for exhibitions or portfolios.
  •  Archiving important photos for future editing.


RAW: Unleashing Creative Potential

RAW files, the digital negatives, capture all data from your camera's sensor with no in-camera processing. These files are a post-processing haven, offering maximum flexibility to adjust exposure, white balance, and more, retaining the highest detail and dynamic range.


When to Use RAW:

  •  Seeking full post-processing control.
  •  Shooting in challenging lighting conditions.
  •  For professional and serious enthusiast photographers.



DNG (Digital Negative): Standardising RAW

Adobe's Digital Negative aims to standardise RAW formats for better long-term compatibility and easier opening in various editing software. While converting to DNG might increase file size, it's a practical choice for future-proofing your work.


When to Use DNG:

  •  Preferring a standardised RAW format.
  •  For long-term archiving and compatibility.


PNG: Transparency and Graphics

PNG (Portable Network Graphics) is known for its lossless compression and support for transparency. This format is ideal for images requiring a transparent background, such as logos or web graphics.


When to Use PNG:

  •  For images with transparent backgrounds.
  •  In web design, graphic elements, and digital artworks.




Understanding these file formats is essential for any photographer. Your choice can significantly influence the quality and adaptability of your images. JPG is your friend for everyday use and web display. TIF and RAW are the pillars of professional quality and editing depth. And PNG stands out in graphic work with transparency.

Experiment with these formats to discover what best fits your photography style and needs. As you gain more experience, your discernment in choosing the appropriate file format for each project will sharpen. Embrace these formats' versatility and watch your photography skills flourish!
