I attended the Mixed Light course on Friday 10th February at your Manchester store. I feel the way in which Jason taught was disappointing. Key points are as follows - 1) There were no reference slides or notes which means delegates had to simply keep up or lose the thread of his point.I mentioned emailing notes out after the course but as with any training / education process its better to have something to look at as you learn. Consider the different ways different people retain information - audio / written / visual etc.. 2) Whilst asking what we wanted to get from the course Jason wrote a note about me that said 'what is photography?' and passed it to another delegate. I'm sure he meant this as a 'joke' but its knocked my confidence and very unprofessional on his part. 3) I arranged a train around the published end time(3pm) only to find the course was running late I therefore missed the end of the session and questions time. Finally, for you Calumet, you need to find photographers who can teach. They may not have the most glamorous experience but they need to be able to come prepared, get their point across to mixed abilities, leaving people feeling they've learnt from the experience.
