HankB Offline Image Upload: On p.1 #1 · D70 wireless ttl I just wanted to give a heads up to D70 and D70s shooters that may not be aware that the D70 has full i-ttl wireless capability with a sb600 or sb800 flash. No other attachments are needed. This is a huge feature advantage to use the flash off the camera, or hand hold the flash with out the sc-17 or sc-28 ttl cord which is about 50.00 bucks. The reason i wanted to post this is we had a customer go out and by a $300.00-$400.00 wireless radio slave, when she already owned the sb800 flash. She was not aware you could use the D70 full ttl wireless directly with the sb600-800 off camera. Edited on Aug 29, 2005 at 03:45 PM Aug 27, 2005 at 11:04 AM

tazo Offline Image Upload: Off p.1 #2 · D70 wireless ttl You will still get a shadow with the flash and most lenses, albeit a small one, even at 1/16 power. Also, I can never get the D70 to do anything but underexpose when using wireless and one sb800. Any tips? daniel Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 05:48 AM

David R Offline Image Upload: Off p.1 #3 · D70 wireless ttl Daniel, Using an SB-600/800 wirelessly the flash is off the camera and the on-camera flash does not contribute any image illumination. So you shouldn't be seeing any lens shadows with this setup. Re your underexposing with the D70, are you sure the wireless i-TTL is set up correctly, with D70 in commander mode, flash on channel 3, group A?

tazo Offline Image Upload: Off p.1 #4 · D70 wireless ttl David, First off, I appreciate your help. Secondly, I have been using the D70 in commander mode, usually manual 1/16 power to conserve battery life on the camera. I have however been using the flash in SU-4 mode. Guess this is the wrong way to go! How do I use a second sb800, if I want it on the same power setting? Just set it to channel 3, group A as well? daniel Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 06:25 AM

David R Offline Image Upload: Off p.1 #6 · D70 wireless ttl Daniel, Are you using an SB-800 on the camera and you want to control a 2nd SB-800 as well? Or do you just have one SB-800? There's nothing wrong with using manual flash - I used SU-4 mode all the time with my D70 so I could use both the onboard flash and and my SB-800. It worked well, but it was a pain to get exposures right. Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 01:56 PM

fcobb Offline Image Upload: Off p.1 #7 · D70 wireless ttl This is a great feature of the SB600/800. I do, however, have a devil of a time with the blinking the preflash causes in small children. I've gone to manual in commander mode to eliminate the preflash but then it's trial and error for a couple of shots till I get the exposure right for my lighting setup. I have the sb600 and 800 and i"m shooting photoflex umbrellas and have no problem getting them to fire simutaneously. With older folks I make them aware of the preflashes and to try to avoid blinking. Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 02:07 PM

Just set it to channel 3, group A as well? daniel In the interests of helping out and maybe learning a bit more myself, as I have read the manual many times and still only understand a fraction of this... What works for me using a single SB800 is this: set the camera to commander TTL mode, (not manual or AA - don't know what they do...) and set the flash to remote, (not su-4) and set its channel/group to A3. Point the SB800 at your subject and press the shutter. It's as complicated as that. The camera sends out preflashes to fire the SB800. The SB800 fires at reduced charge so that the camera can measure the SB800 and ambient exposure through the lens. The camera then sends more flashes to the SB800 to tell it how big a burst to fire and the SB800 finally flashes its main pulse as the shutter opens. It's a marvel to behold and I love it. I don't think you can trigger multiple SB800s from the D70 because I think it only fires on A3 and I guess you may get a conflict. To trigger multiple SB800s you need another SB800 on the camera and you set up the flash layout you're firing on that master unit. It then sends out control pulses to all the flashes out there in the groups and they fire off test flashes one by one as the camera integrates the exposure. It can be included in the mix as well (its designation is M) or just be used to fire the remotes (unlike firing from the D70 alone where its little flash cannot be included in the mix ( - that would have been icing on the cake!!!)). Finally the master SB800 sends out instructions to each flash, the shutter opens and they all fire. It must look like a cacophony of flashes on a big setup. Where I lose the plot slightly is between groups and channels but maybe someone else could shed some light ? Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 02:43 PM

I'm firing a 600 and an 800 on A3 with the D70 on board flash with no problems. I assume it will do the same with 2- SB800's as well Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 04:53 PM

DaveLandry Offline Image Upload: Off p.1 #11 · D70 wireless ttl This Advanced Wireless CLS stuff with the SB800's and 600's is all really cool stuff... BUT I've come to realize that it's really better for "product" or landscapes than people... the preflashing almost guarantees blinkies. I'm trying to get good at the FV (flash value) lock functionality Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 05:16 PM

Both flashes will think the triggers are for them, the D70 will think the combined exposure-pre-flashes come from the one gun (i.e. it doesn't care how many there might be) and both units will flash when the D70 triggers the main flash. I'm guessing that you regulate relative gun powers by moving the guns different distances from the subject? Nice Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 05:22 PM

Nice Yep You can regulate by adjusting distances but if you use commander in manual mode you can adjust flash strength in camera. However, the the same signal is sent to both flashes. IE; if set to 1/32, both flashes fire at that value. If you want to vary the signal to both then an on camera SB800 is required in the master mode where you can control groups.

mrimpossible Offline Image Upload: Off p.1 #14 · D70 wireless ttl Wow this is much cooler than I thought. What are the channel numbers for? Surely not to avoid interference between rival set-ups at close quarters? Is this another pap feature (like "active" VR mode on a lens). In case a bunch of paps are close together, each with a clutch of SB800s, waiting for the celeb to stumble out of the night club? Edited on Aug 29, 2005 at 03:45 PM Aug 28, 2005 at 06:47 PM

mgowin Offline Image Upload: Off p.1 #19 · D70 wireless ttl The manual is lousy on the flash details. I'd recommend Thom Hogan's D70 eBook (see http://bythom.com/d70guide.htm). The flash help alone is worth the price of the book. Aug 29, 2005 at 03:45 PM
