I'm bumping this to see if there is still interest in offering this feature. I don't expect to be able to control the camera, but I would like the ability to specify the capture folder, name captures on input, apply a Stationary Pad and backup to 2 drives and change any of these settings on-the-fly.
I don't know if it's been mentioned before, but it is already easy to use PM through the Canon EOS Utility- with or without Live View. As long as PM is the active application it does a good job of seeing and displaying the images as they come into the computer- although I sometimes need to use Rescan (shouldn't this be in View column next to Refresh? But that's another story). I can set the Capture Folder and the File Naming in the EOS Utility. IMO PM is already superior to DPP, Lightroom and ACR for this functionality. Unfortunately, if PM is not the active application you have to bring it forward before it will show new images.
If there were a way to have PM continue to monitor and update the capture folder, even while it's in the BG, I'd have most of what I want. Add the ability to set and apply a Stationary Pad on download and I'd have 80% of what I need. To get me to 100% you'd need to eliminate the need to set things up in EOS Utility, but I think 80% would be great.
There is one other feature that I'd love to see included. CaptureOne Pro can take any jpg and use it as an overlay with the ability to adjust size, position, opacity and rotation. This is very useful when shooting to a layout. I don't know how many people would want and use this feature (you might be surprised), but if added it would add functionality that is sadly lacking in almost all other tethered solutions.
BTW, I'm using the Canon 1DsM3.
