Getting started with off-camera flash
The moment you take the flash off the camera, light gains direction and shape — the difference between snapshot and portrait. Here's a simple one-light starting point.
Recommended settings
Trigger: Wireless trigger on camera + receiver on flash
fires the flash off-camera reliably
Flash mode: Manual, start ~1/8 power
consistent, repeatable output you can dial in
Position: 45° to the side and slightly above
classic, flattering portrait light with shape
Modifier: Softbox or umbrella
enlarges and softens the source
Shutter: At or below sync speed
controls the ambient; flash lights the subject

Why it works
On-camera, light hits the subject flat from the lens axis. Off-camera, you choose the angle — so you sculpt with highlight and shadow. Manual power gives you repeatable results, and a modifier turns the small flash into a soft, window-like source.
Beginner tip
One light at 45°, in a softbox, at 1/8 power, with the shutter at sync speed — adjust power until the face looks right. That single setup covers most portraits.
Going further
Use the shutter to control the background (ambient) and flash power to control the subject — they're largely independent.
Common mistakes
- Putting the light straight in front of the subject, losing all the shape you gained.
- Leaving it in TTL and getting different exposures every frame.
FAQ
Do I need expensive lights to start?
No. One basic flash, a wireless trigger, and an umbrella are enough to get directional, professional-looking light.
Manual or TTL for off-camera flash?
Manual, for portraits — it gives consistent, repeatable output frame to frame, which is exactly what you want when the light isn't moving.
