A technical scuba diving blogger, Brett Eldridge, shares the challenges and process of creating a photogrammetry model of the HMCS Yukon wreck. Despite difficulties aligning photos due to changing conditions and seaweed, after 11 dives and 14 months, the model was completed. The blog post details the extensive process, including model creation and key statistics, like 150 million faces and 11,750 photos, with a total build time of 51.5 hours excluding alignment time. The model showcases significant detail and required innovative solutions to overcome challenges encountered during the dives.
