Learn to set up the Canon Speedlite EL-100 for portrait lighting, from basic settings to off-camera flash, with practical tips and common mistakes to avoid.

Quick answer

Set up your Canon Speedlite EL-100 for portraits by starting in TTL mode, adjusting flash exposure compensation, and then moving to manual power for consistent, controlled lighting.

Why the EL-100 suits portrait work

The Canon Speedlite EL-100 is compact but capable, with a guide number of 85.3′ at ISO 100 and 50mm. That's enough power for most indoor and outdoor portraits, especially when you're close to your subject.

Its tilting and rotating head (90° up, 330° around) lets you bounce light off ceilings or walls for softer, more flattering results—something a built-in flash can't do.

TTL vs. manual: which to choose

For quick shoots or moving subjects, TTL (through-the-lens) metering is convenient—the flash automatically adjusts power based on the camera's metering. But TTL can be inconsistent if your subject moves or your composition changes.

Manual mode gives you predictable output, which is ideal for static portraits where you want consistent lighting across multiple shots. Start with TTL to learn, then switch to manual as you gain confidence.

Step-by-step setup for portrait lighting

Mount the flash and set to TTL: Attach the EL-100 to your camera's hot shoe and turn it on. Set the flash mode dial to TTL for automatic exposure. This is the safest starting point for beginners. Check that the flash is securely locked and the camera recognizes it before shooting.
Adjust flash exposure compensation: Dial in a negative flash exposure compensation (around -1/3 to -1) to avoid a harsh, overexposed look. This is especially useful when the subject is close. Review your first test shot and adjust compensation if highlights are blown out.
Tilt or rotate the flash head for bounce: For indoor portraits, tilt the flash head upward (60-75°) to bounce light off the ceiling, or rotate it to bounce off a wall. This softens shadows and reduces harsh contrast. If the ceiling is colored or very high, bouncing may not work—use a diffuser or go direct with a lower power setting.
Switch to manual mode for consistent power: Once you're comfortable, switch the flash to manual and set power to 1/4 or 1/8 for close-up portraits. Adjust as needed based on your test shots. Manual mode is ideal when the subject stays in place; re-check settings if the distance changes.
Try off-camera flash for more control: If your camera supports wireless triggering, remove the flash from the hot shoe and use it off-camera. Position it 45 degrees to the side for classic portrait lighting. Start with the flash at 1/2 power and adjust aperture or ISO to get a balanced exposure.
