1. What was the 'special event' at the time of this photograph?
2. Who and how many were around at the time?
3. What was the colour of the vehicle 'involved'?
The tip is to become fully relaxed and establish a totally clear mind, devoid of any thoughts, emotions and any other distractions. The secret is then to really imagine yourself within the image. Seeing beyond the parameters of the photograph. The knack is then to switch off the logical mind and really connect with your intuitive side .... then in almost a daydream state, write down the very first things that come to you ....
Good luck.
