This one has been due for a while. The questions are in no order. I'm only going to address the ones I can give a good answer to and the ones involving the gear I own or have used before so I don't give anyone false information. If I miss something, message me on my Facebook! =)
How do you use a Paul C Buff modifier with your rovelight/XPLOR? Aren't the mounts different?
Correct! They are different mounts. The Paul C Buff modifiers come with the Buff mount. I ordered a Bowens mount off Amazon and switched the Buff mount out for the Bowens one.
Admittedly, I got the wrong size and was even sure it was the wrong size when I ordered it but it was Amazon and I'm an impatient person. What I did was cut off the extra edges with a can opener and boom, problem solved. If you don't want to do this go HERE and order the right size. If you're cheap like me, a daredevil, also impatient, or a mixture of all those things then order the wrong size right here on Amazon.
Update: The one on Amazon isn't available anymore so it's best to just order the right size on B&H.
What do you use to connect the Yongnuo Yn622c trigger to the Rovelight and how do you keep it from swinging?
I use this cord right here. I didn't want a long messy cord so I got the smallest one I could find. I added this velcro to the trigger and side of the strobe to keep it in place, but you can also find some better velcro at your local hardware store like Lowes or Home Depot.
The Rovelight comes with a remote trigger already. Why do you use the Yongnuo triggers?
The people at Adorama didn't add HSS functionality to the included trigger so it only works with your camera's max sync speed. I only use the Flashpoint trigger to adjust the power output. If it couldn't do that it would never see the light of day.
Do you utilize a ND Filter in order to be able to use such a wide aperture?
Nope! I use something called High Speed Sync (HSS). The Rovelight I use has it, but not all strobes are created equal. Some, like the Alienbees, don't have it so that's when you'd need a ND filter. Before I bought the rovelight I used NDs and hated them. That's why I love HSS.
Would you suggest the Rovelight over the Alienbee 800?
YES! Here's why; the Alienbee doesn't have HSS, it needs the vagabond power source which is clunky, it's max power is 320W which is a little over half the power of the Rovelight, it doesn't have a trigger to change the power output like the Rovelight, and it's more expensive combined with the cheapest power source (vagabond mini) than the Rovelight.
Can I use the Yongnuo Yn622c TX instead of the non-TX model?
In theory that should work since it's essentially the same, but don't take my word for it.
Are you able to control the output of the Rovelight using the Yongnuo trigger?
Nope! That's why I use the FP trigger all the time.
Is the 5 ft octabox you use heavy and does it go crazy in the wind?
I'll tell you one thing. I'm weak and can carry that octabox easy peasy. So no, it's not too heavy at all. Although the modifier is amazing, yes, it does pick up wind pretty easily. The shot below was taken in lots of wind that's why the model's mother was helping my girlfriend.
Do you use just one light outdoors?
Yes, about 99% of my shoots involve just one light. I'm a sucker for shadows! If I'm not feeling in a shadow-y mood then I use the sunlight for rim/hair light like in the shot below.
How are you shooting at ISO 50 on your Canon 6D?
Boom! Look at the settings below and you'll be able to shoot there as well. Keep in mind that you will loose a stop of Dynamic Range by doing so. Personally, it's not an issue with me at all. If you use off camera lighting as well then it shouldn't be an issue for you either.
