8.3 RAW vs. JPEG file formats

RAW files are digital photography's unprocessed gems. They contain all the data from your camera's sensor, giving you maximum editing flexibility. However, they're bigger and need special software to view and edit.

JPEG files are the ready-to-go option. They're compressed and processed in-camera, making them smaller and widely compatible. But this convenience comes at the cost of reduced editing potential and some quality loss.

• RAW format contains minimally processed data directly from the camera's image sensor, retaining all original image data including color and brightness information
• Allows for extensive post-processing adjustments without significant loss of quality but requires specific software to view and edit the files resulting in larger file sizes compared to JPEG
• JPEG (Joint Photographic Experts Group) is a processed and compressed image format that applies automatic adjustments such as white balance, sharpening, and color correction
• Compresses the image data to reduce file size which can result in some loss of quality but is widely compatible with various devices and software making it suitable for immediate sharing and printing without further editing

RAW vs JPEG advantages

• RAW preserves maximum image quality and detail, allows for extensive post-processing adjustments, provides greater flexibility in adjusting white balance, exposure, and color, and supports non-destructive editing allowing for reversible changes
• However, RAW has larger file sizes requiring more storage space, requires specific software for viewing and editing, has longer processing times due to larger file sizes and required post-processing, and is not suitable for immediate sharing or printing without conversion
• JPEG has smaller file sizes allowing for more images to be stored on a memory card, is widely compatible with various devices and software, suitable for immediate sharing and printing without further editing, and has faster processing times in-camera and during post-processing
• However, JPEG's lossy compression can result in reduced image quality and detail, has limited flexibility in post-processing adjustments without degrading image quality, permanently applies white balance, exposure, and color adjustments to the image, and repeated editing and saving can lead to further quality loss due to compression

Flexibility of RAW files

• RAW files provide greater flexibility in post-processing due to higher bit depth (12-14 bits per channel) compared to JPEG (8 bits per channel) and preservation of original image data allowing for more extensive adjustments
• Editing potential of RAW files includes adjusting white balance without losing image quality, recovering highlight and shadow details more effectively, fine-tuning exposure, contrast, and color settings with greater control, and applying non-destructive edits allowing for reversible changes and experimentation
• Limitations of editing JPEG files include reduced bit depth limiting the range of adjustments without introducing artifacts, permanent application of in-camera processing limiting the ability to make significant changes, and repeated editing and saving leading to further quality loss due to compression

Choosing between RAW and JPEG

• Storage capacity and buffer speed: RAW files require more storage space which can limit the number of images that can be stored on a memory card and may slow down the camera's buffer affecting continuous shooting speed
• Workflow and post-processing requirements: RAW files require specific software and more time for post-processing while JPEG files are more suitable for situations where immediate sharing or printing is required
• Intended use of the images: RAW files are preferred for images that will undergo extensive editing or be printed in large formats while JPEG files are suitable for images that will be shared online or used for smaller prints
• Skill level and time constraints: Shooting in RAW requires more time and skill for post-processing while JPEG files are more convenient for beginners or situations where quick turnaround is necessary
