How to shoot through-the-window flash for artificial shadows in high-end real estate photos

1.Why Through-the-Window Flash?

When people hear “through-the-window flash,” they might imagine harsh, artificial lighting that fights the existing ambient light. However, the goal of this technique is the opposite: to create a balanced image with deeper, more intentional shadows and highlights. In high-end real estate images, these shadows can add drama, depth, and a sense of luxury.

The trick is that you’re combining a powerful off-camera flash (usually placed outside or peering through a window) with traditional bracketed exposures for High Dynamic Range (HDR) blending. The flash shot delivers those strong, well-defined shadows and highlight pops, while the HDR shots capture the scene’s natural light and color detail. By compositing these images in post-production, you can selectively paint in the shadow areas without losing essential detail in areas like ceilings, window views, or dark furniture.

2.Essential Gear

Camera and Lens

A full-frame camera works best for capturing wide real estate images without excessive distortion. In the video demonstration, a Sony A7 III is used, but any comparable mirrorless or DSLR camera will do. Pair it with a wide-angle lens (generally between 16mm and 24mm on full-frame) to capture as much of the room as possible.

Flash and Trigger

To achieve strong, controllable light, you’ll want a strobe unit like the Godox AD600. This flash has ample power to illuminate an interior scene from outside a window. It is paired with a Godox X2T trigger in the demonstration. The key is to ensure that your trigger and flash can communicate reliably over the distance between your camera position and the flash’s location.

Light Stand

A sturdy light stand is crucial, especially if you’re setting up your flash outside. Real estate shoots may require placing the flash on uneven ground, so invest in a stand with a stable base or sandbag it for extra security.

3.On-Site Setup and Shooting Workflow

The shooting workflow is straightforward but requires careful planning:

Frame Your ShotDecide on your composition. Ensure that your vertical lines are straight (tilt your camera or use a tripod with a built-in bubble level, if possible). This is crucial for professional real estate imagery.Take the Flash ExposureTurn on your flash trigger (the Godox X2T, for example) and set your strobe (AD600) to full or near-full power.Position the flash outside a window or door so it shoots inward, creating the artificial shadows you desire.Take a single shot with the flash active insingle-shotmode to capture the dramatic lighting effect.Capture Bracketed HDR ExposuresTurn the flashoffso it won’t affect the bracketed shots.Switch the camera to continuous bracket mode (e.g., three or four exposures at different EV steps—often ±2 or ±3 EV, depending on your preference).Capture a series of bracketed photos. These exposures will be merged to recover details in the highlights and shadows and ensure a well-balanced final image.Repeat as NeededMove from room to room, replicating this approach. Always remember: one shot with flash on for the dramatic shadows, plus a bracketed series with flash off for HDR blending.

4.Examples from the Field

Living Room Example

The transcript mentions taking a living room shot where you see a huge difference between the first “natural light only” capture and the “flash pop” version. The flash exposure injects strong highlights and crisp shadows that add contrast and dimension. Afterward, the photographer collects multiple HDR frames to ensure there’s enough latitude to adjust bright elements on the ceiling or retrieve detail from dark corners.

Kitchen Example

Kitchens are prime spaces where reflective surfaces—like granite countertops, glossy backsplashes, and stainless-steel appliances—can benefit from a flash. By placing a strobe outside and firing it through a window, you add dynamic shadows along cabinets or walls. This creates a high-end feel that soft, ambient lighting alone often fails to achieve. Meanwhile, your bracketed exposures keep windows from blowing out and floors from going black.

5.Post-Processing in Photoshop

One of the most critical steps is compositing your flash exposure with the natural HDR exposures in an editing program like Adobe Photoshop. Here’s a recap of the technique demonstrated in the transcript:

Load Layers into PhotoshopSelect your flash exposure image, your normal HDR exposure (or the merged HDR if you’ve already run it through a program like Lightroom), and any additional darker or brighter exposures for window pulls.Open them as layers in one Photoshop file (usingFile > Scripts > Load Files into Stackor by selecting “Open as Layers” directly from Lightroom).Auto-Align LayersIn Photoshop, highlight all layers.Go toEdit > Auto-Align Layersand choose “Auto” to ensure any slight shifts between shots are corrected. This is crucial for a seamless blend.Set Blend ModesPlace your main flash layer on top. Set it toLuminosityblend mode. This makes the flash layer primarily affect the brightness of the image rather than dramatically shift colors.Below it, keep your base HDR layer (or the main natural exposure) for overall color and detail.Mask in the Shadow LayerSelect the flash layer, then add a layer mask.Invert the mask (Command/Control + I), so the flash exposure is hidden initially.Use a white brush on the mask topaint inthe portions of the flash exposure you want—mainly those appealing shadows and highlights that give the image depth.Adjust the brush opacity or flow to control how strong you want the artificial shadow effect to appear.Mask in Any Additional DetailsIf you’ve created a layer to recover specific areas—like a fireplace or a dark corner—add a layer mask and paint those details in selectively.You can tweak exposure and white balance for each layer through tools like Camera Raw Filter before or after masking.Window PullsTo properly expose windows, use an underexposed bracket or a dedicated window pull shot.Add a mask and use a lasso or pen tool to select the window areas.Invert or refine the selection to reveal the well-exposed outdoor view.If needed, run Camera Raw Filter on that layer to fine-tune highlights or exposure so it blends naturally with the rest of the interior.Retouching and Finishing TouchesRemove any stickers, cords, or distractions using Photoshop’sGenerative Fill,Spot Healing Brush, orContent-Aware Fill.If there is a TV screen in the shot, consider replacing it with a nature or scenic image for a polished, luxurious feel.Lastly, crop the image to correct composition if needed—straightening lines, ensuring symmetrical alignment, or removing extraneous space that doesn’t serve the shot.

6.Practical Tips and Considerations

Power and DistanceAlways double-check that your strobe’s power is sufficient for the distance between the light stand and the interior. Full or near-full power is often necessary for large spaces or bright sunny days.Avoid OverkillWhile the dramatic look can be stunning, it’s possible to go overboard and make the space appear too artificially lit. Use masking techniques subtly, focusing on areas that benefit most from added contrast.Multiple Window PlacementsIf a room has multiple windows, try shifting the flash to different windows for separate shots. This can give you more options in post, where you can decide which angles of light look best.Bracketing SequenceCommon bracketing sequences are ±2 EV for a total of three shots or ±3 EV with four or five exposures. Pick a bracket that gives you enough dynamic range to capture the brightest highlights (like windows) and the darkest shadows (like under cabinets).Editing EfficiencyIf you’re shooting an entire property with this method, develop a streamlined workflow. Batch your images for auto-align and initial adjustments, then mask in flash details on a shot-by-shot basis. The more you practice, the quicker your editing process becomes.
