scott_roberts4 Posted February 17, 2007 Share Posted February 17, 2007 HELP! Ok, please don't boo me off here, because I know this is probably a really dumb ass question, but I am only a beginner, so I am technically not very knowledgable! My question is, that I have a 580ex speedlite, and I am using a 1DS canon digital camera. I am also using a portable studio kit - (brand is - falcon eyes) (http://www.falconeyes.com.hk/diyhp/12224/enus/c-54677/p-AAAV+EAAVAAANZ+AAc/Basic_Entry_Level_Amateur_Compact_Studio_Kit.html) Anyway, what I want to find out if anybody can help me out, is can I use my 580ex as a wireless transmitter to fire the Falcon Eyes flash head (Model No: SS-150B) that I am using in my softbox? The kit also has two other heads (both model: SS-110B). If I use a horse shoe - sinc cord I can fire the 150 model, but not the 110?!? I also just read somewhere that the electrical current that can go through the camera via a sinc cord, can damage it, so I am trying to work out if the 580 EX can be used as a transmitter, without actually flashing itself? If anyone can help in any way it would be greatly appreciated! Thanks Scott Link to comment Share on other sites More sharing options...
miklosphoto Posted February 17, 2007 Share Posted February 17, 2007 Hi Scott, I would think that if your Falcon Eyes have a slave switch they can be triggered by the flash of the speedlite. But that means you will need to fire your Speedlite. That is the only way to use your 580EX as the master. Hope this helps. Miklos Link to comment Share on other sites More sharing options...
mark u Posted February 17, 2007 Share Posted February 17, 2007 You will need to set the 580EX to a low MANUAL power setting to avoid the pre-flash that would trigger your slaves too early. Link to comment Share on other sites More sharing options...
scott_roberts4 Posted February 17, 2007 Author Share Posted February 17, 2007 Guys thank you so much! That is really good advice! I will try it out, and see what happens. If anyone has any other advice please let me know. Link to comment Share on other sites More sharing options...
scott_roberts4 Posted February 17, 2007 Author Share Posted February 17, 2007 just tried that. I went to mode then chose M and set it to 1/128, and even though the falcon eyes has no slave switch it has a censor that picks up the 580EX flash and fires it! Thank you!

J.W. Wall Posted February 17, 2007 Share Posted February 17, 2007 If you want to use your Speedlite at a higher intensity, you could hook a Wein digital peanut to the PC socket of your studio flash. The peanut will ignore the preflash and fire at the correct time. Link to comment Share on other sites More sharing options...
richard_hopkins Posted February 17, 2007 Share Posted February 17, 2007 I have used a 580EX to trigger the slave on studio lights. It's easy, after a few experiments. First thing is to buy a box of chocolates with colour cellophane wrappers. Choose a dark red one, pull out the flash diffuser and clip it underneath. Select the loweest manual power output that will trigger the studio light. Richard. Link to comment Share on other sites More sharing options...
awindsor Posted February 18, 2007 Share Posted February 18, 2007 You can also buy a roll of slide film and develop it. Unexposed but developed slide film is black but IR transparent. Often you can turn the head around and direct the flash away from the subject. The sensors on the strobes are normally pretty sensitive. If you are going for a very high contrast shot the light from the triggering speedlite can weaken the shadows. That is where putting a cover on your Speedlite can help.

awindsor Posted February 18, 2007 Share Posted February 18, 2007 Of course for $20 you can buy an ebay radio slave and avoid these problems. Link to comment Share on other sites More sharing options...
