Step 1: Hold your smartphone at eye height with the tree base at the vertical center
Step 2: Start recording the video, make sure the ground takes approximately half of the screen
Step 3: Record an "up scan-line" (film the tree from its base to its top in a regular 5/6 seconds movement) while keeping your smartphone at the same height
Step 3: Make sure the tree top is visible at the end of your "up scan-line"
Step 4: Record the corresponding "down scan-line" (film the tree from its top to its base in a regular 5/6 seconds movement) while keeping your smartphone at the same height
Step 4: Make sure the ground is visible at the end of your "down scan-line" and takes up about half of your screen
Step 5: Once you finished an "up-and-down scan-line", rotate around the tree while keeping the trunk axis at the middle of your video
Step 6: Record a new "up-and-down scan-line" from your new location with the ground taking half of your screen
Step 6: Start by an "up scan-line"
Step 6: Make sure to record the tree top, record a new "down scan-line", rotate around the tree and repeat scanlines until you turned around the full tree
