It's still pre-"Mud Season" here (i.e. the mud is still frozen) so here's a very different version of one from December. 5D mark II with Sigma 50mm f/1.4.
kop.cppua excellent observation and good question. don't tell anybody but to my amazement i discovered in close proximity the master flash 580 EX MKII does not have to see the slave 420EX flash. in other words there is no line of sight between the flash units. how can this be? wrap around, reflection, bounce whatever it works. i have actually had the master unit in front of the slave absolutely no line of sight between the units and the slave still fires. it is my guesstimate that wrap around, reflection, or bounce is occurring and the infrared control signal is being received by the slave. keep in mind that the slave is the old 420EX not the 430EX or another 580EX.
i would like to request other participants that own those units to try it and report on the results. the units must be set up as master and slave respectively on the same channel with A:B ratios active.
i was using a white Teflon card to bounce the control signal into the slave. i was just shooting away i took a break and notice the stupids card fell off its' mount. bingo, that is how i discovered that the units don't have to 'see' one another. i've been shooting this way for over a year now.
hush don't tell anybody they may think i'm crazy because this should not work but it does, lol.
CP, the right tool for the right job. Dual flash units allow for good and interesting light modeling for fill and shadow depth, etc. diffusion for softening the light it works for me. an entirely new world opens up when one can control his light in the field even when the sun is up mid day and very harsh or in the jungle that is very unforgiving and dark under the canopy. thus the name Canon Digital Macro Studio.
i shoot a lot of macro and close-up lots of light is required to pull fine detail from the subjects. i also have designed flash bracketing for hand held scenarios to hold the dual flash units, the CP-E4, and camera lens combo. again the right tool for the right job.
my flash units are mounted almost 100% of the time for close-up and macro work. my mono-tripod is always ready to go if needed to get the shot. again the right tool for the right job.
Thank you all for such nice comments on my flowers. I just love this hobby, along with this site. You all make it a very good source to learn, and get great idea's from!
Mike n CP, love the warmth that the last two photos bring out...very nice.
RH, I really enjoy the first Daisy shot! Great color. Your flash setup is very nice as well, brings you some nice results.
