would like to ask. i just bought the trigger from artworkfoto. but just now i tried in on my 420EX. whe photos are taken under slow shutter speed, the photos were over exposed totally.
but as i change my settings like increasing my shutter speed, half of the photo is totally black, and other half is normal. i tried this with both of my 500D and my friends D90, both showed the same thing. so the point is?is it a faulty unit or my method to use it is wrong?or is there any other reason?
1/400s, iso 200, f4.0
