I recently worked with the guys at PPL Photo Agency on a studio day, and had a great time doing so!
The communications beforehand were faultless, i turned up extremely informed for the day ahead, knowing exactly what to bring along, what was expected of me and what i was to expect. Both Andrew and Jonathan made me feel right at home, and all of the photographers that booked on to the day were a joy to work with. I also had my own dressing/changing room that is genuinely big enough to swing a lion in!
If you ever have the chance to work with these guys in this wonderful space then do not turn it down!
