I’m not familiar with Hasselblad Raw files. But I have had a good experience with Fast Raw Viewer which swiftly reads through the embedded jpegs in Raw files and is great for quickly culling images. I believe it reads CFV files.But...out of all the file formats and camera types that I use and have used, those darn Hasselblad files are the only ones I find to be a bear to cull after uploading because PM and PM+ will not render thumbs. Bridge kind of works but is clunky as is LR as a DAM.
