Optical Trigger Trouble

[martycon]

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!

Thanks for the info JJ, having been around so long they must be good.

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.

That narrow field of view definitely makes sense. thanks JJ
