We have just released a new version of StereoCore™ PhotoLog. The new version contains no new features per se, but we have spent a lot of time tuning up the program so that it runs faster and more reliably. We noticed that for larger project files where lots of data was collected in deep (> 1000m) holes the program would slow down noticeably when logging, and obviously this was bad, so we did something about it.
You can dowload the update here: http://www.stereocore.net/downloads.html
We've also added a new section of write-up about our pricing policy to the website, which you can look at here: http://www.stereocore.net/pricing.html
Briefly, StereoCore™ PhotoLog is free to download and use as a program - you can install it on as many machines as you like, and you can always get updates and bug-fixes for free. You only pay for "image activations" which allow you to use the digital core tray images for logging.
Happy Logging :)
