[QUOTE="rocketman122, post: 316294, member: 14443"] Im always in awe how much you know regarding flash, because its not typical. many pros I work with dont know much about light and do a trial and error to get results. its sad that many dont take the time to understand flash and are quite scared of it and have a hard time with it. but flash is complicated and there is a lot to learn. I would say that the difficulty is understanding light/flash but also understanding how to mix it with the camera. thats a different discussion yes the thyristor. when Dttl was the main balanced tech they had a few years back many pros I worked with preferred A thyristor over the ttl or Dttl options. they said they got much better results. its possible, as the digital world was just starting to bloom with the D200. I did change it now to FX in the SB900. the Sb700 was FX. I will recheck it as it is set now. yes, very unreasonable, almost leading me to believe that for sure I messed something up. when I first saw it I went to the flash to make sure I set it correctly. I will also make a video showing how it is set for each flash. what I meant about the SB900 is that its been used so much, that maybe the reason is weakened capacitors that are a bit tired...? for those needing just basic features, like TTL, manual, strobostic, and CLS (which I hate) the 565 and 568 are just fantastic. I beat on my 560III and it just says thank you sir may I have another. and with a smile HAHA Im not really good with these calculations. its not that I cant understand it, but when I see numbers I lose patience and have to walk away. my brother is a real mathematician. an elite programmer/developer and was a regional chess champ. he has a very binary head. hes the brains, im the art. regarding the distance, why cant I just use them all at 1m (or 2 or 3 or whatever) and just fire them and test what their Fstop is? im not looking for a scientific test. I basically want to see what it can pump out at full power at the 35mm mark at iso 100 at 1m. is this wrong? I just dont have a straight line that long. and when I did the test, there was just one spot led light for ambient so I could see what I was doing but it 10' away. [/QUOTE]
