California based @mike2swim / Mike Lewis shared this BTS image from a session with USA Swimming national team member and Pan Pac silver medalist Katie McLaughlin. Mike mounted his Delphin D4 housing to the floor of the pool just in front of the starting blocks and fired the camera via a 20ft 3 pin cable and switch. Mike also ran a 6 pin sync lead from the flash bulkhead to his flash housing to allow for him to add some high side lighting from the waters edge pool side. This is an uncropped file to show Mike in action. Nikon D4 camera + 16mm lens used. Follow Mike and his great swimming images at @mike2swim ~ #aquatech
