Shaded Window Light and the Direction It Comes From
With simple gear, the main light for product photography is a window that receives bright daylight without direct sun landing on the item. Light like this is scattered, so shadow edges stay soft and the surface of the product looks evenly lit. Direct sun does the opposite job: hard-edged shadows, blown-out white patches on shiny surfaces and contrast that is hard to rescue in an edit. The first task for a learner is therefore an easy one. Watch the windows at home across the day and note when the light is bright yet shaded. Late morning and afternoon usually deliver it.
Direction matters as much as strength. Side light, with the window to the left or right of the item, reveals the weave of fabric, the grain of wood and the curves of packaging, because every small bump casts a thin shadow. Front light flattens all of that and makes the product look like a cut-out, while light from behind darkens the face turned toward the camera. A useful drill is to keep one item on the table and move it so the light arrives from the front, the side and the back, then compare the three frames side by side on the phone.
When the sun is too strong, thin white fabric or tracing paper hung over the window acts as a diffuser. Distance also controls softness. An item placed right against the glass gets a glaring bright side and a deep dark one, and sliding it a little further back makes the transition smoother. One habit worth building from the very first session is switching off warm-coloured room lights, so the window is the only source and the product's colour stays clean.
Shaded side light, one source per session and a carefully adjusted distance are the base of every product photo.
