If you're a pro, why wouldn't you want the best software available for the job. You can bet your top competitors will be using it.
I can't even comprehend how you can say that C1 images don't look any better than the Canon FVU, or ACR for that matter. Every comparision I've seen done on RAW converters, C1 wins hands down.
With all due respect Michael, you must not of learned how to use C1 properly. How many images did you convert using the demo? Did you give it a fair chance?
It's not that I don't like Photoshop, I've been using it for over 10 years, but when it comes down to producing the highest quality RAW conversion, C1 is the software I will use.
As for the price of $500 for just a RAW converter, if you want the best that's the price you pay. If my business was full-time photography, I wouldn't even think twice about making such a purchase. It would pay for itself in the first month with time saved and better quality images.
I've tried the demo version of c1 and the images don't look any
better than they do from canon's file Viewer Utility. The only
advantage is that the preview is full size and faster. The
conversion time is not faster at all.
