About this time last week, James O’Neill was explaining to me how Windows Image Acquisition (WIA) could be used to control my camera over a USB connection. I’m not sure if he told me, or if I suddenly realised, but somewhere along the way came the realisation that I could use this to take a picture – i.e. to drive the camera remotely – and James very kindly shared some Windows PowerShell commands with me.<\/p>\n

Today, James published the results of his work, saving me a lot of research into WIA and a related subject – Picture Transfer Protocol (PTP)<\/a> but, unlike James’ Pentax K7, it seems that my Nikon D700 will allow me to use this to actually take a picture (I haven’t tried on my Canon Ixus 70… with or without the CHDK<\/a>).<\/p>\n

James’ code showed me how to call WIA as a COM object:<\/p>\n

$WIAdialog = New-Object -ComObject \"WIA.CommonDialog\"
\n$device = $WIAdialog.ShowSelectDevice()<\/code><\/p>\n

Following this I had an object called $device that I could manipulate as I liked and $device | get-member<\/code> returned the following methods and properties:<\/p>\n

   TypeName: System.__ComObject#{3714eac4-f413-426b-b1e8-def2be99ea55}<\/p>\n

Name           MemberType Definition
\n—-           ———- ———-
\nExecuteCommand Method     IItem ExecuteCommand (string)
\nGetItem        Method     IItem GetItem (string)
\nCommands       Property   IDeviceCommands Commands () {get}
\nDeviceID       Property   string DeviceID () {get}
\nEvents         Property   IDeviceEvents Events () {get}
\nItems          Property   IItems Items () {get}
\nProperties     Property   IProperties Properties () {get}
\nType           Property   WiaDeviceType Type () {get}
\nWiaItem        Property   IUnknown WiaItem () {get}<\/em><\/p>\n

$device.Properties<\/code> was kind of interesting but with $device.Commands<\/code> I was really getting somewhere:<\/p>\n

CommandID                               Name          Description
\n———                               —-          ———–
\n{9B26B7B2-ACAD-11D2-A093-00C04F72DC3C}  Synchronize   Synchronize
\n{AF933CAC-ACAD-11D2-A093-00C04F72DC3C}  Take Picture  Take Picture<\/em><\/p>\n

Seeing that there was a command to take a picture got me thinking and looking back at the device methods I could see ExecuteCommand so I tried calling it:<\/p>\n

$device.executecommand('{AF933CAC-ACAD-11D2-A093-00C04F72DC3C}')<\/code><\/p>\n

I was amazed to find that my camera did exactly what it was told and fired the shutter!<\/a> I need to do some more testing, to see if I can control the focus, or return a live preview, etc. but controlling a remote device, over a USB connection, using nothing more than a few basic scripting commands made me feel like a real techie again (even if it was James’ code that got me started!). Who knows, I may even teach myself to code again (as I’ve threatened several times over the last few years) and write an application to remotely control my camera.<\/p>\n

Ironically, at the start of last week I was trying to figure out how to take time-lapse photos of the extension that I’m having built on my house right now but it wasn’t software that held me back, it was practical issues like leaving a camera outside for days on end in all weathers and providing power to it. Now, if only I had a 25 metre USB cable (!), I could hook up a cheap webcam and set a script to take a picture every hour or so…<\/p>\n
