Why are my photographs always underexposed?

PROBLEM 01: UNDEREXPOSED PHOTOGRAPHS

Are your photographs too dark or even black when using the Retra Flash?

If your photographs keep coming out underexposed or black when using the Retra Flash, the problem may lie in a mismatch between the mode settings on your camera, housing trigger and the Retra Flash.

Read on to learn how to troubleshoot the problem and fix the issue.

PROBLEM 02: HIGH ENERGY CONSUMPTION

Is your Retra Flash using too much energy?

If you find that your Retra Flash has high energy consumption, the problem may be a mismatch between the selected modes on your camera, housing trigger and the Retra Flash.

Read on to learn how to troubleshoot the problem and fix the issue.

DIAGNOSTICS TEST

  1. Connect the Retra Flash to your camera housing
  2. Set the Retra Flash to M (Manual mode) and turn the power dial to 100
  3. Trigger your camera and check the results

If the Retra Flash was triggered and the image comes out under-exposed or black, please follow the solutions provided below.

If the Retra Flash was not triggered, please double-check the optical connector and try again.

SOLUTION

OPTION 01: Set Retra Flash, Camera & Housing Trigger to compatible modes

Refer to the user guide for the trigger board and camera for instructions on configuring settings to emit a single pulse (manual mode). Adjust the trigger board and camera settings accordingly to generate a single pulse (manual mode).

Turn the mode dial on the Retra Flash to M (Manual).

Try the diagnostics test once again.

OPTION 02: Set the Retra Flash to SSL mode

If your camera emits only TTL light with pre-flash(es), and you wish to set the Retra Flash with manual exposure, you can use the SSL mode - Smart Slave Mode (default position - U, U2) on the Retra Flash.

The Smart SL mode will automatically detect a TTL signal and the number of pre-flashes (1-10) and ignore them.

Every time you enter mode "U" or "U2", the Retra Flash will first go through a calibration process.

Calibration procedure:
1. Retra Flash Pro Max: Follow on-screen instructions / Other Retra Flash models: Follow instructions below
2. A pulsating light will appear, indicating the Retra Flash is ready
3. Trigger the camera once and wait for 2 seconds
4. If the light stops flashing, the Retra Flash has been calibrated and will fire with manual power settings (same as in M - manual mode)
5. If the light keeps flashing, please exit the "U" mode and try again


If your photographs still come out under-exposed or black when your camera and Retra Flash have been set to Manual mode (single pulse) and your Retra Flash has been triggered, or if your Retra Flash still has high energy consumption, please contact us at help@retra-uwt.com.
