Advanced Flash Techniques
Lighting Techniques | 10 min read
Once you've mastered basic bounce flash, it's time to level up. Advanced flash techniques let you handle any property — from windowless basements to sprawling open-plan spaces — with complete control over the light.
One speedlight can only do so much. For larger rooms or spaces with multiple zones (kitchen-diner, L-shaped living rooms), you need two or three flashes working together.
1. Place your main flash (key light) in the largest area, bounced off the ceiling
2. Add a second flash in the adjoining space or dark corner
3. Use a wireless trigger system — the Godox X2T trigger can control multiple groups independently
4. Set each flash to a different group (A, B, C) so you can adjust power individually
5. Fire a test shot and balance the groups until the lighting feels even across the entire space
The goal is seamless coverage. When you look at the final image, every zone should feel naturally lit — no bright spots, no dark patches, no visible transition between flash zones.
Light painting is a technique where you fire a single flash multiple times during a long exposure, illuminating different parts of the room with each pop. It's slower than multi-flash but produces incredibly even, natural-looking results.
1. Set your camera on a tripod with a 2-4 second exposure at ISO 100
2. Set your speedlight to manual mode at 1/16 to 1/32 power
3. During the exposure, walk through the room firing the flash at different areas — ceiling, walls, dark corners
4. Aim away from the camera and bounce off surfaces
5. Keep moving so you don't appear in the shot (wear dark clothing)
6. Review and repeat, adjusting your flash positions until coverage is even
This technique works brilliantly in large spaces like hallways, open-plan living areas, and commercial properties where even multi-flash setups struggle to reach every corner.
Flash is daylight-balanced at approximately 5500K. Most interior lights are much warmer — tungsten bulbs sit around 2700-3200K, and warm-white LEDs are typically 3000K. If you fire bare flash in a warm-lit room, you get an ugly mix of cool and warm light.
The solution is CTO (Colour Temperature Orange) gels:
1. Attach the appropriate CTO gel to your speedlight using the magnetic mount or gel holder
2. Set your camera white balance to tungsten (or the Kelvin value matching the room lights)
3. Fire the flash — it now blends seamlessly with the ambient warm light
4. The entire image will have a consistent colour temperature
Pro tip: Buy a gel sample pack and test different strengths in your most common shooting environments. Most property photographers find 1/2 CTO covers 80% of situations.
The most natural-looking property photos balance flash with the existing ambient light. Pure flash looks artificial; pure ambient often has dark shadows and blown windows. The sweet spot is a blend.
1. Take an ambient-only exposure: Set your camera to capture the room with natural light. Accept that shadows will be dark and windows may be bright.
2. Add flash at -1.5 to -2 stops below ambient: This lifts the shadows without overpowering the natural light feel.
3. Adjust the ratio: More flash = brighter shadows but less atmosphere. Less flash = moodier but more natural.
So if you want more ambient and less flash feel, slow your shutter speed. If you want more flash impact, increase flash power or open your aperture.
Beyond basic bounce, these modifiers give you more control:
Key Takeaways
- Use multi-flash setups for large or multi-zone rooms — one flash per area
- Light painting creates incredibly even results for challenging spaces
- Always gel your flash to match ambient light colour temperature
- Balance flash at -1.5 to -2 stops below ambient for natural-looking results
- Shutter speed controls ambient, flash power controls flash — use both to fine-tune the balance
- Adapt your flash strategy to each room type — kitchens need gels, bathrooms need careful angles
