TESTED: Apple Mac Studio M1 Ultra: RAW File Conversion, PhaseOne IQ4
Consult with Lloyd on your computer or photographic purchase, backup strategy, archival and storage strategy, etc.
A big thank-you to B&H Photo for sending the $7999 Apple Mac Studio M1 Ultra 20-core CPU / 64-core GPU/ 128GB / 8TB SSD for review. This is exactly the configuration I would buy excepting a preference for a 4TB SSD (only to keep the cost down).
