Start with the photograph
What are you trying to fix?
Choose a portrait genre and a concrete lighting problem. Work from source distances or isolated meter readings to get a shooting plan, then verify it in camera.
Boudoir
- Face brighter; chest three stops lower — Find the point-source geometry, check whether it fits, then compare two isolated meter readings.
- Keep shape without losing shadow detail — Build an editable key/fill contribution difference at a chosen combined flash aperture.
Family
- Light every row and keep eyes in focus — Plan source distance and a focus position while testing your aperture, room and power limits.
- Darker sky; normally exposed faces — Start from separate background and subject ambient readings, then solve camera settings and key flash.
Portraits
- Separate a portrait from a darker backdrop — Solve a finite illumination difference using source angle and actual subject-to-background separation.
- Give the key more presence than the fill — Calculate isolated key/fill targets that add up to your chosen camera aperture.
Maternity
- Keep face and bump within half a stop — Test a gentle distance-only difference and identify when room or modifier geometry makes it impractical.
- Lower an overpowering rim by one stop — Reduce only the separately metered rim; preserve key and fill, then inspect fabric and spill.
Headshots
- Make the fill one stop below the key — Design a modest independent contribution difference without confusing it with a final facial contrast ratio.
- Reach a measured face-exposure target — Translate a flash-only meter reading into the power adjustment for your chosen target aperture; camera-check important highlights.
Goals such as a darker backdrop or softer fill are creative choices. Example readings do not describe your scene. Use the same ISO, isolate each flash and confirm capture before following a power estimate.
Start with the photograph you want to make
Different shoots create different practical problems. This guided tool connects boudoir, family, portrait, headshot and maternity goals to the same measurable exposure and placement principles. Suggested creative targets are starting experiments; enter your own measurements before applying a power setting.
- Choose the genre and the specific problem, then adjust the suggested goal to your intended photograph.
- Enter the geometry or isolated meter readings the problem needs. Check space, power and model limits in the result.
- Make the suggested change, remeasure the important subject points and photograph the result. Use the linked specialist tool for a more detailed plan.
A boudoir face-to-chest target of three stops means one-eighth of the illumination at the chest. A family group might instead tolerate only half a stop across its rows. The artistic goals differ, while both require clear source-to-subject distances and a meter check.
Will choosing a genre set my flash power automatically?
No. A genre identifies the goal. Power recommendations require an actual meter reading at a known power, or another explicitly measured reference.
Are these fixed rules for lighting people?
No. Change the target for your subject, pose, wardrobe and intended mood. Skin tone and final image processing affect how the measured light looks.
Can I use the tools with my Godox lights and Sekonic meter?
Yes. Enter your actual gear, power limits and readings. The tools do not substitute a model name for a measurement.
