The purpose of the pictures is to document the workshop steps (welcome, amassing, illumination, like, etc.) and the atmosphere at the workshop and capture visual results (e.g. flipcharts, play-doh or lego models).
Your images will be a nice souvenir for the participants (we will share a collection online) - it's also a good catalyst to get buy in of the workshop results from people not attending the workshop.
The images can also be used to project during breaks or arrival time of the participants after breaks.
The customer and BrainStore can also use the images as good example for a nice workshop.
Ideal moments to take pictures of participants are
There will be one moment for the group picture. You can find it in the workshop script. If it's not in the script yet, include it :-).
During the amassing phase please make sure that you have one good shot of every flipchart, drawing and 3D model the participants create.
It's important that we have multiple images of every participant: the person working in a team and images of the person only.
Please don't focus only on the participants you find attractive :-).
Take sure everyone is on the group picture and everyone sees the lens. Take at least 8 or 9 group shots. This is not a popularity contest.
