So, let's talk hypotheticals for a bit since I'm way too excited for these to arrive. Let's start with my car photo I posted previously. If I had that same situation happen again at dusk with these two new 560EXs, where would I start with my camera settings? I realize with only two strobes and an entire car there's a chance I may have to do multiple exposures and stitch them together in Photoshop. So I'd probably set up one flash camera left at front of the car and one camera right at the front wheel/quarter panel.
90% of the time, I shoot in aperture priority mode. Depending on my situation I usually let the 6D choose ISO (because it has such stellar ISO performance) but occasionally I'll lock it at ISO 100. I'm not afraid of Manual at all.
So now that I've got my flashes set up, I'm looking at switching to Manual, no? Set ISO at 200, speedlights at 1/4. I'd be shooting with my 24-105L most likely. I'm quickly realizing I don't fully understand what aperture/shutter/exposure value I'll need to deal with. So overwhelming haha
Heya,
You can do it in one exposure just fine.
There's lots of ways to do this, but here's what I would start with.
Camera settings will be based on exposure of ambient light and depth of field. You don't have to use the maximum synch speed of 1/180s. I would actually just go to 1/100s. Stop down aperture based on depth of field depending on what you want. Use ISO to further adjust ambient light exposure, and it will indirectly also increase the power output of your flash. Where ever the sunset point is, that can be your "rim" light for free, adding a little light to the edge of a side. I would use the flashes at 24mm (widest setting on the flash) and at lower power (starting around 1/16th power and adjusting from there based on taste) to simply add fill light to the car, opposite sides from where the sunset point was. One can be higher power, and act as a key light. The other can just be fill and at lower power. This will give it a more dramatic look without looking "all flashed." The important thing will be to watch for the flash reflections in the car and the last big thing will be to mix ambient and flash light temperatures (flash is 5600k or "daylight" temperature; the ambient light is going to be very different at sunset/dusk, so gelling your flashes to a temperature closer to ambient temperature will have them blend better and not look like obvious flash). Then just play with the power settings for the flashes to taste. It will not take much to fill the car and bring out the lines.
Again, camera settings will be ambient exposure & depth of field. That's all you need to remember in terms of setting your camera. You can easily figure this out with Live View and real time look at it with a histogram. It's really nice to slightly underexpose ambient light by 2~3 stops. So in this case, I'd drop ISO to 100. Shutter to whatever it takes to get exposure you like of ambient light based on whatever aperture you're using (F8, F11, etc, for depth of field), and then you're done with that part of the camera. Then you just bring in flash and that's your other exposure, and the power level will do this part, so just start at a power setting and go up or down based on what you want to see. Light drops off fast the further it is away from the subject, so if you place them far away start at a higher power, if they're up close, start at a lower power. Chimp a few shots and you'll know right away if you need more or less power for what you want it to look like.
Very best,
