Test face light with a neutral reference before the portrait run
Check exposure and colour on the actual subject instead of trusting the backdrop.
A backdrop or clothing sample cannot tell you whether the face is well exposed. Make the lighting test with the person who will be photographed, preserve skin detail in the highlights and shadows, and avoid treating one camera preset as universal.
Set a neutral baseline
Use one steady light source and place the subject where the final portrait will be made. Turn off coloured decorative lights for the test. If you use a grey card, place it at the same angle as the face, then remove it before the sequence.
Review the face
Take one frame and inspect the brightest skin areas and the darker side of the face. Adjust exposure or light position in small steps. Do not brighten the entire image until highlights wash out; a white reflector can lift shadows without changing the backdrop as much.
Repeat after changes
When clothing, background or room light changes, repeat the face-level test. Check colour on the saved file as well as the preview. If skin colour shifts between frames, lock white balance or simplify the lighting; avoid automatic corrections that vary from image to image.
