RAW to HPG: what carries over and what does not
RAW files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to HPG bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. RAW is made of pixels and HPG is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a HPG container, and that determines whether a CAD or design tool can work with it.
