I have a question about my sb600 flash and my d90 built in flash. I'm back to doing some more waterdrop pictures, and if you all remembered I was totally frustrated by the fact that after I finally got some drops streaming down into my glass dish, my camera would stop taking the pictures and we all came to the conclusion that it was due to the safety of the flash not overheating. My question is this: was that my sb600 or my d90's flash that was preventing me from clicking the shutter? I can't remember. And if it was the camera, would the 300 allow me to take my shots longer? I know I have a heck of a way of explaining things, but long story short, here is the process. I have my bag of water suspended from my tripod above a glass baking dish full of water. I have my camera on a tripod aimed at where my drops will be hitting the water in the dish. I have my flash off camera mounted on a stand sitting beside my dish of water aimed at my background, (that's how I get my colors of my drops.) I then poke a small hole in my bag of water that's suspended and the drops start to drip in the dish. I then use my remote chord and start clicking. It will let me get quite a few shots in one right after another, but it never fails, as soon as I start to see some cool looking drops, my camera stops firing and I have to wait, it seems like forever, (which irritates me, then I can fire off maybe 2 or 3 more clicks and then I wait again. Of course, by that time, I'm so irritated because my water from my bag is draining. See what I'm saying. So, back to my long story short, is it my camera's flash that is doing the overheat safety thing or is it my sb600? Just couldn't remember? And what could be my solution to this problem or isn't there really any just more patience on my side,,(that won't happen hehehe) Hey, one more thing, has anyone ever used the "stop shot" system? It's something that hooks directly to your flash that syncs, or so they say, to the drops.
>I have a question about my sb600 flash and my d90 , is it my camera's flash that is >doing the overheat safety thing or is it my sb600?
Do either even have a thermal cutout? A quick search of the flash manuals seems to indicate the thermal cutout wasn't added till the SB700 & 900.
When I was doing testing while replying to your original thread about water drops I usd my SB800 and D7000 with the WCLS and also with the SC-29 and never ran into a shutdown issue. On the other hand I would suggest that if you are firing many shots in a row that the camera's buffer might be at issue, not the flash overheating.
It is easy to tell in that when you run into the pause, look at the back of the camera for the memory access lamp. If it's flickering green, it's a memory buffer issue.
Hey Pete, how's it going? No, that's the first thing I looked at and it isn't the buffer. I remember talking about this before on here, and I think we finally figured out that it was some kind of safety thing but I can't find the thread and I don't know which one was the problem. At first when I was using my 600 ON the camera I had that problem, then when I moved my flash off camera it gave me a little more clicks, but still slowed way down after the first round fired off. I mean, I let the camera sit for a couple of minutes and start shooting again, but that is such a pain when my water is dripping away. See what I mean?
Ahhh Pete sorry to hear that things could be better. Remember, everything happens for a reason......I checked that link to the thread and yep, that was it...So I am thinking that it is the d90 flash that's the culprit and I guess there is no way around that. Anyone know if the d300 would pose the same problem for me? Just wondering....
Okay, dug out my sc17 chord, attached it to the camera and the flash, and it doesn't fire. Is there something else I need to do to make it work? I have the camera in commander mode still, the onboard flash at -- . I can still use my remote correct? Don't know why it isn't working.
OK, OK, SO I PANICKED!!! It wouldn't work, because duh, I had it in commander mode, and SINCE I'm not using my camera as a commander per say, it doesn't need or will WORK in that mode. So, I reset everything back to ttl and there you go...See, I'm getting it,,,the hard way, but I'm getting it.....yippee...
