After 21 posts and many well-meant advice, still not one person has offered what the OP has asked for. Looks like everybody is creating images only for exhibitions. Of course, Capture Integration too is shy to show raw images.
Yes, this is very strange...
Also, Phase website, no raw files to be seen. Ditto for Capture Integration, a link leading to nowhere when I checked earlier.
If only someone could explain the reason why.
My own theory is that the sellers don't want to lay their cards on the table. They want you to call them so they can give you the sales talk, like, there's much more to a digital back than a raw file, there's the workflow, after sales, bla, bla, bla. We know, believe me, we know all that.
I'm sure the reason is driven by sales. But not everybody wants to call the dealers for a demo initially, they may want to have a preliminary examination of files, ask a few people around and so on. Much like buying a car, you read reviews, you buy magazines, you compare prices and options....then, eventually, you make up your mind to go to the dealers for a test drive.
Since the process of buying a medium format digital back is shrouded in secrecy, from dealers prices to vested interests, to inaccurate or non existent reviews and comparisons, how can anyone blame someone who is a little confused at the very least, and wants to see some initial proof with his own eyes, call it the carrot, before taking further steps.
I've had five camera backs and countless DSLRs, I know the importance of workflow, software integration, after-sales service, reliability, warranty, replacement policy, etc. but I've always wanted to see files beforehand, before I call the reps, and I know I'm not the only one.
