A lot of people ask and I don’t know — it probably does work as it is using a standard Windows way of talking to the camera — WIA — but I don’t have the hardware to test it.
If a camera supports a “PTP” or “MTP” mode — and if when plugged into a PC it is visible in My Computer under the section for Scanners and Cameras
(not as a removable disk drive) then it is liable to work. The only big gotcha I can see is that some cameras — all the P&S I’ve tried — will not let me press the shutter button while they are plugged into the PC. It seems that ability is a DSLR thing.
So, if you happen to have a non-Nikon DSLR handy and don’t mind spending a few minutes testing I’d be delighted to hear whether this script works for you. Obviously for Canon users it’s beside the point as proper remote control software is included with the camera — but it is still technically interesting.
If you get any results please leave me a comment, many thanks!
