Presentation of the participants and the monitors.
Materials needed: mobile phones of the participants, some rope, plastic bottles (of 2 and 5 liters, empty containers), scissors, cutters, permanent marker. We don´t use it, but it is also possible to use cardboard.
To start we suggested an exercise to work with our hands and start solving step by step how to hang a camera from a balloon that takes picture.
How to get the camera to be horizontal?
Making of a rope swing (rig or harness) so the camera is horizontal. The participans use their own phones as cameras.
How to protect them against hits?
Making the case from plastic bottles or other containers .
How to get a camera that doesn´t turn over because of the wind?
Puttng glue to the case so it works as a vane (explaining the swivel hitch).
How to hang cases to the rope?
Explaining how to unite with a carabiner to not generate extra tension to the rope.
How to activate the trigger of the camera in continuous mode?
Gum and scotch tape to activate the trigger.
How to blow a balloon?
How to blow up a balloon, tying it and to the rope.
How to transport the balloon?
Precautions to prevent that the balloon blows up.
What happpens if we loose the balloon?
Adding contact mode to the case and in the camera.
The participants take turns for the transport tasks (holding the rope, the balloon, dropping and picking the rope, trigger the camera, pick back the camera).
18.00h is little bit late to start making pictures: the light starts disappearing, so the pictures are more blurry, and the longs and variable shadows make it more difficult to join the pictures to start making the map.
We had enough time to fly three times over the square of Puerta del Sol. The camera used was a Canon1300 and a minicamera MobiusAction Cam.
We save for the end an introduction in the context of the workshop and the motivations. We wanted to leave for the end these part that is more theoric.
Materials: laptops, tablets, pen drives and hard disks to share the pictures.
We went on discussing again the pictures of the previous day and they were distributed among the participants . The collective task was to review the pictures and to select the best to use them to crate a map of the square. It was suggested to the participants to discharge the pictures that were: moved, blurry or taken from too close.
The workshop with families had a similar methodology. The first day we went to take pictures to Vázquez de Mella square and the second to Puerta del Sol. At some time the wind was very strong, but thanks to a good teamwork we achieved to get back back the balloon safe and sound.
