Anthony 0 Posted October 2, 2003 I just bought a YS90DX to complement my S45. I was wondering if anyone could give me a few tips before I hit the water. Mainly I was wondering now that I'm using an external strobe, what mode I should use my camera in? I normally have it on P, but will this cause my shots to be over-exposed? Any tips would be much appreciated! Thanks. Share this post Link to post Share on other sites
maecki2 0 Posted October 2, 2003 Hi Anthony Normally the camera is fireing a pre-flash to measure the object. If the YS-90 also fires at the pre-flash everything is fine. Otherwise you have to reconfigure the YS-90. I had this problem with my YS-60. For me i had to open the YS-60 and reassemble some cables. But the YS90 should be capable of fireing 2 flashes within some ms. Share this post Link to post Share on other sites
vlad 0 Posted October 2, 2003 ... OR you could disable the preflash from the S45 camera. I have a S50 and I shoot in C mode and what I did is that I have the flash always on and shoot in Av mode. Vlad Share this post Link to post Share on other sites
Anthony 0 Posted October 3, 2003 Few questions... 1. Should I set the ISO to auto or a manual setting? (This can't be altered once the camera is in the housing) 2. What is the best mode to shoot with? Aperature priority, Shutter priority, or P? 3. Because I dont have TTL, how do I adjust the strobe output to my camera settings? Sorry for all the annoying questions, but this is all new to me. I'm trying to find a bit of literature. Thanks Share this post Link to post Share on other sites
vlad 0 Posted October 3, 2003 Hello, Here is what I think 1. Should I set the ISO to auto or a manual setting? (This can't be altered once the camera is in the housing) >>>>I think you should set it to 50 or 100. 2. What is the best mode to shoot with? Aperature priority, Shutter priority, or P? >>>It depends. I shoot in Av but I can see why you would want to set the time and then let the aperture be set automaticaly. Definitely not P 3. Because I dont have TTL, how do I adjust the strobe output to my camera settings? >>>>You don't! You will have to try settings. Although ... I think if your strobe can take the preflash, you could do TTL and everything should be OK. My strobe is crappy so I can't even set the power on it. I usualy set it to about 5 for aperture and then the time is usualy 1/60 or so. Vlad Share this post Link to post Share on other sites

The flash sometimes cannot synchronize with the camera even I have set the 90DX to PRE position. Daniel Share this post Link to post Share on other sites
ReyeR 0 Posted October 7, 2003 I don't have an S50 but you can disable the pre-flash by setting the 'Flash Adjust' to 'Manual'. The pre-flash is automatically disabled in M mode. You can then set the Flash Output in 3 steps - select the lowest setting that will trigger the YS-90DX. This will save batteries and help the camera's flash to recycle faster so you can take the next shot quicker. Don't forget to set the YS-90Dx to 'On' instead of 'Pre'.
