How to Merge Two Photos in Gemini (Couple & Family Prompts)

How to merge two photos in Gemini: copy-paste couple, family, and pet prompts, plus fixes when the light or the faces look wrong.

Updated October 9, 2026 · AI Prompt Grid editorial

Quick answer: How to merge two photos in Gemini: attach both photos in one message, then paste a prompt that names each photo and keeps both faces exact. A merge two photos AI prompt like the ones below also works in ChatGPT if you number the images. Use them for a couple, a family, friends, or a pet.

Before you paste

  1. Open Gemini and check the model is not set to Flash-Lite. That option is not built for several reference photos.
  2. Attach both photos in the same message, in the order the prompt names: first photo, then second photo.
  3. Ask for one shared light so the people look photographed together.
  4. Check the faces first. If the light, the height, or a face is off, use a short follow-up in the same chat. The tips at the end are for that.

Similar light and a similar crop merge more easily than a close selfie plus a far full-length shot. Skip sunglasses and heavy beauty filters. Only merge photos of people who agree to it.

Couple merges

1. Riverside couple

A couple photo merge AI prompt: two separate photos become one riverside walk, with one shared late-afternoon light.

Prompt
Merge the first uploaded photo and the second uploaded photo into one natural group photo of a couple standing side by side. The first uploaded photo shows person A and the second uploaded photo shows person B. Follow the selected source-preservation settings: identities and facial features. Always keep person A's face shape, eyes, nose, lips, hairline, hair, any beard, glasses, or head covering, apparent age, and exact skin tone as in the first uploaded photo, and person B's exactly as in the second uploaded photo. Treat them as two separate people; do not blend, swap, beautify, slim, de-age, or lighten either face, and keep natural skin texture. Keep the outfit each person wears in their own photo. If group arrangement and pose are not preserved, stand them close together, one arm around the other's shoulder, both smiling at the camera, with realistic relative heights. Light both people with one warm, low sun from the left so they look photographed together, with matching shadows and color temperature. Apply luminous golden-hour warmth color grading. Replace the background with riverside promenade with a calm river, trees along the bank, and warm late-afternoon light, keeping clean edges around hair and clothing. Do not add extra people, text, lettering, or logos. Compose for 4:5 Portrait without cropping either face.

The people and animals in the before photos are AI-generated, not real. Every after image on this page is an AI edit of those two sources.

If the merge looks wrong

Send these in the same chat. They are follow-ups, not new style pages.

Fix mismatched lighting

Prompt
The two people look lit differently. Keep both faces and the background exactly as they are, and relight the whole image with one consistent light source from the left: same brightness, warmth, and shadow direction on both people.

Fix scale and height

Prompt
The sizes look wrong. Keep both faces and the background the same, but make the scale realistic: one person about a head taller than the other, both at the same distance from the camera, feet on the same ground level.

Fix blended or swapped faces

Prompt
The faces have been mixed. The person from the first photo must match that photo exactly, and the person from the second photo must match that photo exactly. Restore each face separately, keep their natural skin tones, and do not change anything else.

Fix a pasted-on look

How to blend two photos in Gemini when someone looks cut out: ask for matching edges, shadow, color, and grain.

Prompt
The second person looks cut out and pasted in. Keep both faces the same, and blend that person naturally into the scene: soft edges around the hair, a matching shadow on the ground, and the same color grade, grain, and sharpness as the rest of the photo.
