Why does my electronics 3D model dark in photography?

Your electronics 3D model looks dark in photography usually due to insufficient or poorly positioned lighting in the 3D scene. - 3D renders rely entirely on artificial light (no real-world ambient light)—weak key lights (main brightness) or missing fill lights (soften shadows) hide details. - Dark or matte materials (like plastic casings) absorb more light, making the model even darker. For a quick fix, use a three-point lighting setup (key, fill, backlight) to balance brightness and shadows. For dark materials, slightly brighten the fill light to counter absorption.
