Does a higher-resolution photo give a better swap?

Up to a point. Sharp and reasonably close beats blurry every time, but past a clear, well-lit head-shot the extra pixels add little — angle and lighting matter far more than raw megapixels.

Can I use a photo where I'm wearing glasses?

Clear glasses are usually fine. Sunglasses are not — the model needs to see the eyes, and a swap over dark lenses looks wrong.

The Best Photo for a Face Swap (and What to Avoid)

Most disappointing face swaps come down to one thing: the source photo. The model is handed a single still image and has to rebuild a whole head from it, so the picture you choose matters more than the video does.

Why the photo matters more than the video

A face swap takes one still image of the face you want and maps it onto the people in your clip, frame by frame. The video supplies the movement, the lighting and the angles; the photo supplies the identity. If that photo is unclear there is nothing for the model to lean on, and the result looks off no matter how good the clip is. So before you think about the video, get the photo right.

What works, and what causes trouble

Works well	Causes trouble
Looking straight at the camera	Strong side profile or looking down
Even, soft light on the whole face	Hard shadow across one side
Eyes open and visible	Sunglasses, or hair across the face
One person in the frame	A group photo
Sharp and reasonably close	A tiny face in a wide scene

Lighting

Flat, even light is your friend. A face lit evenly gives the model clean information about skin tone and shape. A half-shadowed face forces it to guess what is hidden, and guesses are where swaps go wrong. Daylight near a window, or any soft indoor light without one harsh source, works well.

Angle

A front-on or near-front-on face swaps best, because that is the view the model has the most to work with. Photos taken from below, sharp profiles, or faces tilted far to one side are harder — the swap has to invent the parts of the face the camera never saw.

One clear face

Use a photo with a single face. In a group shot the tool tends to pick the largest face, which may not be the one you meant, and nearby faces can confuse it. If your only good photo is a group one, crop it down to the person you want first.

A ten-second checklist

Facing the camera, not in profile
Even light, no hard shadow
Eyes visible, nothing across the face
One person, reasonably close and sharp

Tick those four and you have removed most of the reasons a swap looks wrong. The rest is the clip — and there, a face that stays roughly front-on and is not lost to motion blur will always swap more cleanly.

Only use a face you have the right to use. Putting someone into a video without their agreement can cause real harm, and in many places it is against the law. Use your own face, or one you have clear permission for.
