most (not all, some contributions are QTVR-only due to historical reasons)
many, but depends on photographer's choice of file upload (newer event = more likely to work) and your device's capabilities. You may experience slow playback, distorted images or unexpected browser quitting if there is only limited memory/GPU power available.
Well it was bad weather in Northampton, England on 20th March but I was determined to take a shot at the exact time of the Equinox - 06.49 GMT, even though it meant an early start! As I was heading out to the car, my son woke up and wanted to come with me, hence the little boy in the picture... I just wanted to clarify in case some of you thought that was me :-)
This is one of the first QTVR's I've produced and wasn't too disapointed considering the pour conditions but would welcome any feedback.
