Study Notes
Choosing Digital Image Formats
- File Type Selection: The choice of file format depends on the task and required file size; smaller file byte sizes do not always equate to less information.
- TIFF Quality: TIFF files provide the highest quality for digital images through lossless compression, ideal for storage during editing, but have large file sizes.
- JPG Compression: JPG files are commonly used for web images due to high compression capabilities, but quality diminishes with repeated saves; one or two saves may be fine, but after about ten, degradation occurs.
- GIF Usage: Best for images with fewer than 256 colors, such as graphics; not suitable for photographs due to color limitations.
- PNG Benefits: Preferred for images with large areas of uniform color and supporting more than 256 colors; it is the only lossless format supported by web browsers, allowing partial transparency.
- RAW Files Overview: RAW files capture all camera information similar to a film negative; ideal for editing, but should be converted to JPG or PNG for sharing on platforms.
- Editing with RAW: Allows adjustments without significant degradation of the image; consider RAW as “camera film” and JPG/PNG as “photo prints”.
- Image Editing File Formats: Graphics software images (e.g., PSD, PSP) should retain original formats during editing, with final outputs saved in TIFF, PNG, or JPG.
Compressing & Sharing Multiple Files
- File Compression: To send multiple files, compress them into a ZIP folder, reducing storage size while retaining all information.
- ZIP Creation on PC: Right-click on the folder or files, select "Send to" > "Compressed (Zipped Folder)" to create a ZIP file for email sharing.
- ZIP Creation on Mac: Right-click the folder or files and choose "Compress folder (or # items)" to create an "Archive.zip" for sharing.
- Cloud Storage Sharing: Upload the file folder to cloud storage (Google Drive, Dropbox, etc.) by dragging and dropping, then share it directly.
- Information Integrity: Regardless of sharing method (ZIP or cloud), no information is lost or removed; only size or quality may change while the content remains intact.
