Just an anecdote: I had my name in the credits a couple of years back. I was one of the beta testers and lent them a couple of photos for them to include the white balance and sharpness in the Canon EOS 300D I had back then. I had been offered a rebate by the developer but never got around to buying it, finding it was very slow and sluggish to navigate with Picture Arena.

Now that I have an iMac G5 maybe I should try it again.
