No, I mean the center one. I know it isn't the perfect solution but the far right one, in my experience, completely blows things out. My intention here is more to correct a color balance rather than exposure (which looks fine in the original).
I prefer ACR as well but I don't like to suggest it in case somebody hasn't laid out the cash for the software. A curves adjustment can be done in some free programs. The Pentax software would probably handle it as well. Since however, it has crashed on every computer I've tried it on, I rarely suggest the Pentax supplied software.
