Hi I have a Fuji HS30 EXR and no matter what I try my Photoshop CS4 will not recognise or upload the RAW images produced by this camera (wrong file. not recognised). My other cameras all work fine. Please help.
So far as I'm aware, that camera's not natively supported by ACR for CS4, whereas your older cameras obviously are. I don't think it was supported until late in the life cycle of CS5 (ACR 6.7), and of course CS6 supports it.
You'll need to convert your files to DNG if you want to continue using CS4 with raw files from this camera, or upgrade to CS6.
