Map exposure slider (in RAW tab) to a knob on a panel?

The only "panel" I've ever used with DR is the Tangent Element iPad app. I'm looking to up my game but still haven't decided which panel to get. I actually love the iPad app but the one thing it's missing that I REALLY need is an exposure knob. Do any of you know of any apps for iPad (or even iPhone) that would allow me to map the exposure slider in the raw tab to a knob so I won't have to keep using the mouse? It could be an app or a hardware piece of gear. Or maybe the BM Micro panel? Not trying to spend $3K here for an exposure knob. lol

There's one on the Mini Panel and on the Advanced Panels:



I'll be honest: once I get the basic Exposure/ISO/Color Temp down, 99% of the rest of my adjustments are all downstream with curves, LGG, Log, and the HDR controls. You can get a lot further adjusting those than the Raw controls. In the real world, the Raw controls are much too slow and "finicky" to work with.

Hey Marc,

Thanks for your reply. I agree that if you're a colorist - the raw tab is not where you want to do your color corrections. However, I am not a colorist. I am a videographer. I shoot in raw, process the files, and deliver the footage to my client for them to do whatever they want with it. Therefore, the main adjustments I make are typically white balance and exposure. That's the whole reason I shoot in raw - it allows me the flexibility to change my exposure and white balance after I've shot the clip. So being able to modify the exposure with an actual button or a knob would be a great plus for me. Having to click with the mouse and move that slider becomes a real PITA when you have 100's of clips to go through every week and you're trying to get through them quickly.
