As of the current Smart Shooter v1.0.462 release, the tethering application now provides the ability to change white balance and metering, use a bulb exposure timer, and record each individual live view frame as a still image. It's also now possible to download all photos from the attached camera, and to review them at 1:1 pixel resolution on-screen.
Live view performance and reliability has been improved, and a number of issues including a crash when validating the license on Mac OS computers, and a problem with ISO sensitivity adjustment using the Canon EOS 5D Mark II have all been corrected.
Hart's Smart Shooter application provides some fairly unusual features for tethered shooting, including the ability to create TCL scripts controlling the shooting operation. This allows relatively complex batch shooting operations for time lapses, and even focus stacking.
Smart Shooter is available for both the Windows and Mac OS platforms, priced at £32 -- approximately equivalent to US$50, ignoring exchange rate fluctuations, taxes and duties.
