<p>Hi,<br> Sorry if this is a stupid question but I am new at studio photography.<br> I got Nikon SU-800 as gift and I was told that it should work with studio strobes. Currently in the studio that I am an assistant, we work with Bowens. I tried my SU-800. It seems like it works but the thing is that it triggers the light before the shutter goes off, so there are no lighting in the picture. How can I change that?<br> Many thanks!</p>
