It occurred to me when I was using my mouse to fine-tune one of the 15(?) sliders in Photomatix how greatly a device that actually contained a series of physical sliders or knobs or dials would facilitate the process. If you've seen any audio mixing-type equipment, this is the sort of thing I'm referring to. I know what a lot of you are probably thinking: "Preposterous! Unnecessary! How awkward such a thing would be! The mouse is perfectly adequate!" Yes the mouse is perfectly adequate, but surely there is or at least could exist an alternative for such purposes which would be even better than the mouse. There are joysticks, trackballs, and drawing tablets, but none of those really fit the bill in this case. Anyone have any experience or thoughts on the subject?
