Yes—flipping can be a practical solution for a team composite, but it depends on the portrait.

The main risk is lighting. If the light is clearly directional or asymmetrical, flipping the image also flips the light pattern, which can look unnatural or inconsistent when placed beside unflipped portraits. This is especially noticeable with stronger side lighting and shadow shape.

If the lighting is fairly even or a simple 45° setup that still looks natural after flipping, many viewers won’t notice. In practice, most people won’t realize an image was mirrored unless something obvious gives it away, such as hair parting, clothing details, logos, text, or other directional elements.

A sensible approach is to make a draft composite using flipped versions where needed and review it with the client. If the mirrored portraits look believable and the client is happy, it’s a workable alternative to a reshoot. If the lighting or other details look wrong, reshooting from the opposite angle is the better option.
