    Optical Trigger Trouble

    I have a ring flash conected to an optical trigger, both Yongnuo. The trigger is triggered by my E-M10's small onboard flash. The trigger worked OK in heavy shade, but not in bright shade or sunlight. My solution was to tape white paper over the sensor aperture. With 4 layers of paper it now works ok in bright shade. I will add more paper to see if it will operate in sunlight as well as bright shade.
    Is there a more sophisticated way of doing this?
    I note that the trigger has two tiny switches under a clear cover, which I first mistook to be the sensor.
    cheers marty.

    Don't know if there is a better solution for you but there certainly are better and worse optical triggers on the market. I've been using these Metz triggers for a long time and they work great, even in full sun. I found out recently they have been on the market since the early 1970's!

    They seem to be. I have several (4 or 5) of them and haven't had a problem. The lens on the front of the sensor acts like a telephoto so it potentially has a narrow field of view which can be directed at other flashes. This makes it quite effective in full sun.
