In Topic: On-Camera Flash Setting for Fiber Optic Trigger

07 January 2014 - 02:35 AM

Ok, one more question. My YS-D1 manual say the recycle time is 2 -3 seconds. If that's the case, then lowing the camera flash power will mean that the strobe recycle time will control. Maybe taking them off preflash will improve recycle time, but shouldn't I be concerned that the camera will fire a few frames/sec while the strobes only fire far less often? Won't I end up with a lot of unlit shots because the strobes can't keep up? Thanks.

Thank you both! Ok, this is a dumb question, but...

What's the difference between lowering the flash output and reducing the flash compensation? I've tried reducing the compensation and didn't see any change in recycle time. I thought that reduced output (evidently not or maybe only lowering it 1 or 2 stops wasn't enough).

Also, it seem counterintuitive that lowering the output would use more battery power. Can you elaborate on that?

Very nice!  Please tell us what camera, housing, and lens you used.

Thanks for the responses everyone.  I want to ask about another option:

  1. As with any TC, I know I’m going to lose some sharpness and focus speed at the expense of a bit more range.  So if I crop a shot taken with just the 10-17, will it be sharper or softer than a non-cropped shot taken with the TC.  If the cropped, naked 10-17 shot is as sharp, I don’t see the TC getting me anywhere.
  2. Same question with the Canon 8-15.  Since the reviews/tests I’ve read say the 8-15 is sharper (albeit for a cost), if I get the 8-15, will my cropped shots be sharper or softer than an uncropped shot taken with the 10-17 and the TC?

Any thoughts on this would be appreciated.  Thanks.

Thanks Tom.  That's pretty much what I was thinking, but the idea of being able to shoot humpbacks....they'd be worth shooting regardless (I shot video in Tonga).  But I don't know if it's worth it, I'll probably just stick with the 10-17 and hope any big stuff finds me attractive.
