Digital Images

Definition

Digital Images are digital files that contain visual content such as photographs, fine art renderings, illustrations, or graphic designs. These images exist in electronic formats and can be displayed, edited, and shared using digital devices.

File Formats

• JPEG: Compressed image format suitable for general display and online use, though quality may degrade with repeated edits.
• TIFF: High-quality, lossless format often used for archival and professional printing purposes.
• PNG: Lossless format supporting transparency, ideal for web graphics and layered images.
• PDF: Can contain images along with text and vector graphics, preserving layout and design for sharing or printing.

Color Spaces

• RGB: Red-Green-Blue additive color space used for digital displays.
• CMYK: Cyan-Magenta-Yellow-Black color space used for printed outputs.

Resolution and Quality

• Measured in pixels per inch (PPI) for digital screens and dots per inch (DPI) for print.
• High-Resolution Files: Preserve maximum detail for printing, archival, and professional reproduction.
• Low-resolution or overly compressed files may exhibit pixilation, which reduces clarity and sharpness.

Best Practices

• Maintain original high-resolution digital images for archival purposes.
• Organize images with consistent file naming and metadata for easy retrieval.
• Use appropriate color spaces depending on display or print requirements (RGB for screens, CMYK for print).
• Backup digital images using multiple storage solutions such as cloud and external drives.
