When using reflectors in watch photography, the results are even better. The reflected light from the white or silver mirror is shone on the subject, and the light source is adjusted according to the reflection of the shiny part. Using black glass to contrast the light and dark areas can produce a clear picture of the outline. So how to improve efficiency when using a reflector? First, fix the flash angle, then adjust the position and angle of the mirror until you are satisfied, and finally, make fine adjustments to the amount of light and the exposure angle. When reflections appear on the text plate and the strap, a PL filter works well.
