When sliding towards Dramatic, the camera exposure is decreased and the flash power increased, resulting in an image with darker ambient light (the light that does not come from your Profoto C1 Plus or C1, e.g a lamp, a window, the sky, etc.). The subject will still be correctly exposed. When sliding towards Natural, the camera exposure is increased and the flash power decreased, resulting in an image with brighter ambient light.

My Profoto C1 Plus or C1 flashes more than once per image captured. Why?

If you prefer a faster workflow, you can capture the first image in Auto and then switch to Manual. You then keep the exposure and flash power from the image captured in Auto, and the C1 Plus or C1 will only flash once per image. In Manual, you can also finetune the exposure or flash power if needed.
