I am hopeful that the experienced members here can assist me with some advice on settings with off camera flash. I own an EP1 and an EPM1 & FL36R flash. Instead of staying on the gear upgrade bandwagon, I want to learn more about the gear I currently have. I wish to start using the flash off the camera for portraits and own the Oly 45mm lens. From what I have seen and read on the net the biggest step for me to improve my portrait photography would be to learn the concepts of off camera flash and the use of some tools such as diffusers and reflectors etc. I understand that with the EP1 I will need to trigger the FL36R flash by a TTL cord and I should be able to set the flash in manual mode to fine tune the lighting effects. I have been experimenting with the EPM1 with the RC functions and have a question about this. I have been able to trigger the FL36R off camera either in TTL or manual mode, but I do not understand whether it is better to turn off the onboard clip on flash. Is the onboard flash required to fire to trigger the FL36R? If so, what intensity should the onboard flash be set at to minimise the impact of the flash from the camera? Any assistance would be greatly appreciated. I have reading the olympus school pages online and cannot understand the concepts. One other query would be relating to which body is better for most conditions. Am I correct in assuming that the EP1 with the base ISO of 100 would be slightly better than the EPM1 for portraits when conditions suit to use a cable? Thanks in advance.
