Troubleshooting TIFFs with tiffInfoGUI — Tips & Best Practices

How to Use tiffInfoGUI to Inspect and Edit TIFF Files

What tiffInfoGUI does

tiffInfoGUI is a graphical tool for viewing detailed TIFF file information—image dimensions, bit depth, color model, compression, and embedded metadata (EXIF, XMP, IPTC, TIFF tags). It also lets you edit certain metadata fields and export tag lists.

Opening a TIFF

1. Launch tiffInfoGUI.
2. Use File → Open or drag-and-drop a .tif/.tiff file into the window.
3. The selected file appears in the file pane and loads its tag and metadata panels.

Inspecting image properties

• Summary panel: Shows image width/height, resolution (DPI), sample format, bits per sample, photometric interpretation (grayscale/RGB/CMYK), compression type.
• Strip/Tile info: Displays strip/tile offsets, byte counts, rows per strip or tile size — useful for debugging read errors.
• Preview: Renders a thumbnail or full image (if supported) to confirm content and orientation.

Viewing metadata and tags

• TIFF tags list: Browse every TIFF tag (tag ID, name, type, count, value). Use search/filter to find specific tags.
• EXIF/XMP/IPTC panels: View standard camera and document metadata in human-readable fields.
• Hex/Raw view: See raw tag bytes or full file hex for low-level troubleshooting.

Editing metadata

1. Select the tag or metadata field to change.
2. Click Edit (or double-click the value).
3. Modify text or numeric values; for multi-value tags, add/remove entries.
4. Save changes with File → Save As (recommended) or File → Save to overwrite.

Notes:

• Always back up originals before saving edits.
• Some tags control image layout (strips, compression)—changing them can corrupt the file if done incorrectly.

Batch operations

• Use the batch panel to apply metadata edits across multiple files (e.g., set Artist, Copyright, or change DPI).
• Configure filters (folder, filename patterns) and preview changes before applying.

Exporting and reporting

• Export tag lists as CSV or JSON for inventory or automated processing.
• Generate printable reports showing key metadata and image properties.

Common workflows

• Fix orientation: Update Orientation tag and save; use Save As to preserve a copy.
• Normalize DPI across images: Batch-edit XResolution/YResolution.
• Extract metadata for indexing: Export CSV of selected tags from a folder.

Troubleshooting tips

• If a file won’t open, check for nonstandard compression—tiffInfoGUI may require a plugin or external decoder.
• If edits don’t appear in other software, test with a different viewer; some programs cache metadata or prefer different tag blocks (EXIF vs. XMP).
• Use the hex view to verify tag offsets after advanced edits.

If you want, I can:

• provide step-by-step screenshots for a specific platform, or
• generate a checklist for a common batch edit (e.g., set DPI and add Copyright).
