Widelux: Banding, Flare and Diagnostics Guide
Technical guide, in English, analyzing density banding, flare, and exposure variations in rotating-lens panoramic cameras, specifically the Widelux. Covers artificial lighting (theater, concert, LED, fluorescent, halogen, HMI, discharge), natural light situations, mechanical causes, optical effects, film processing, and scanning issues. Includes diagnostic protocols, visual signatures identification, and practical recommendations for troubleshooting image defects.

Documentation must be downloaded on a computer (PC, Mac, or Linux).
Do not use a smartphone or tablet to download documentation; they generally lack sufficient memory capacity to handle large files, and few users know how to locate the download folder on these devices.
Once downloaded, you can use it right away and even print the pages you need, or use your smartphone in photo mode to translate into the language of your choice: Google Translate
