This training series is created for volunteers around the world undertaking their own Christmas Wish project in their local hospital or hospice.

To find out more about The Heart Project and Christmas Wish please visit:

The Video Training series is made up of 7 videos that go through each step, from set up, to photo shoot to editing.

We use:

  • Nikon Z7 for filming and D850 for tethering
  • Wacom Mobile Studio Pro
  • EIZO monitor
  • Tether Tools
  • Capture One Pro
  • Adobe Photoshop
  • Smugmug Gallery
  • Lightroom CC
  • Elinchrom Strobes and Xlight Modifiers


Although this is created for Christmas Wish specifically, I’m sure that you will find this series generally very helpful for similar Green Screen shoots and edits.
