Yes, a direct-from-neg solution, convenience and accessibility for advanced darkroom users were the point of the product. Plus, it produced really beautiful dyes. Maybe it was the directness of the process or the greater range of color negs, but they could look really spectacular.
I don't recall that it was anything unusual about its sensitivity, but exposures through the blue filter could run quite long.
Of course, this product is long gone except for any that's been hoarded in a freezer. And despite the respect I have for anyone attempting to revise the dye transfer process, I think that the challenges are pretty substantial. I hope the payoff is worth it.
