Seriously no point in using this.. I've been working with this software for a few years, and thought that it's pretty normal, nothing fastastic, nothing the new CS can't do... If I understand correctly, only the phaseone backs are the only one able to shoot tethered... The back's a fine thing, which complement the software...
With the advance technology from photoshop, might as well be CS... 4GB and 8Gb cards are common now.. One option is to shoot raws with jpegs... Look at jpegs, then process the raws...
The money could have been better spent on something else though... If you must part with cash for the software, that is....
If you really must, go to
