I am new to the Inon Z240 strobe (type 4). Started diving w/ it and looking for tips.
I set my Nikon to Flash TTL. On a few dives I connected it with optical (& pop up the Nikon flash) and on a few others I connected it with S&S electronic sync cord. Regardless what connection method, I found every switch on the Inon, I can fire. Sttl, stttl-low, Auto, Manual, Full, everyone, it fire. On every switch (may be not Full), I can dial the EV and get fine adjustment. So while that sounds good, it looks like I have no 'sure exposure' in ttl, isn't it ? If I am shooting TTL-low on macro and I can adjust the EV from max to lowest to get the right exposure, then to me it's not TTL anymore ?!
In the last trip, I was shooting 60mm w/ both Z240 situated to the left & right of the port about 6 inches away from the port, connected electornically, I set the Inon on ttl-low with the fine EV dial down to 11. That seems to generate the least amount of output if I set it at TTL, I got over expose result.
Am I mis-using the product ? How do you typically use yours ?
