Start with the window, not the camera
Choose a window that gives you working room on one side. North-facing windows are convenient in the northern hemisphere because direct sun is less common, but any window works when you can soften direct light with a white curtain or diffusion fabric. Turn off the room lights so mixed color temperatures do not create different colors in the highlights and shadows.
Place the table beside the window rather than directly in front of it. A starting angle of roughly 90 degrees gives shape to most objects. Move the table closer for softer transitions and brighter exposures; move it away for more contrast. Mark the table legs with removable tape once the result is useful.
Control contrast with one movable surface
A sheet of white foam board opposite the window is often enough fill. Watch the shadow side while moving the board: a few centimeters can be more useful than a large exposure adjustment. White card lifts the shadows gently; silver card is stronger and can create sharp highlights on glass or glazed surfaces; black card removes stray reflections and deepens an edge.
Do not assume that brighter is better. The reflector should support the shape established by the window, not flatten it. Take one frame without fill and one with fill. Comparing those two frames is faster than trying to judge a subtle change on the camera screen.
- Window-to-subject distance recorded or marked
- Room lights switched off
- White, silver, or black card chosen intentionally
- Tripod position marked before the set is disturbed
Lock the variables that should not drift
Use manual exposure when the scene is stable. Pick an aperture for the required depth of field, keep ISO low enough for clean detail, and let the shutter speed fall where it needs to on a tripod. Set a fixed white balance or photograph a neutral reference card at the beginning of the session. Automatic white balance can change between nearly identical frames as a colored object enters the scene.
If you work handheld, use aperture priority with a minimum shutter speed and watch ISO. The goal is not a particular number; it is a sharp file with the intended depth of field. Check the histogram and the specular highlights on the product, especially on pale labels and glossy packaging.
Make the setup repeatable
Save a wide phone photograph of the complete setup, including the window and reflector. Note the time, weather, lens, camera height, table distance, and background. These details form a lighting recipe that is more valuable than copying settings from a different room.
Before packing down, capture a clean background plate and a neutral reference. Rename the folder with the date and project, then back up the originals. Repetition is what turns pleasant window light into a dependable studio tool.
