Q: Is the WiFi on the ship fast enough to upload high-res RAW images?

A:

No, the WiFi on most Yangtze River cruise ships is not fast enough for reliably uploading high-res RAW images. Bandwidth is severely limited, with upload speeds often below 1 Mbps. This makes transferring large files (e.g., 30-50 MB per RAW) impractically slow. Connectivity is prioritized for basic web browsing and messaging.

In remote stretches like the Wu Gorge, where I've tracked sunlight on cliff faces, the satellite signal must navigate steep terrain. This introduces latency and dropouts—akin to trying to photograph a kingfisher in dense foliage; the moment is gone before your buffer clears. The system isn't built for data-heavy tasks.

Pack sufficient memory cards to last the entire cruise—I carry a minimum of 512GB in waterproof cases. Only upload small, edited JPEGs via ship WiFi if necessary. For RAW backups, wait for port days with cafes offering land-based internet in Chongqing or Wuhan. Treat the journey as a digital detox, focusing on capturing scenes, not sending them.
