Baby generator guide
Which Photos Give the Best Results in an AI Baby Generator?
Most disappointing results come from the input, not the model. Five rules fix nearly all of them.

The Short Answer
Use a recent, sharp, front-facing photo of each parent with the whole face visible: even daylight, no sunglasses, no hats, no heavy filters, a neutral or lightly smiling expression, and only one person in the frame. Phone selfies taken by a window in daylight are usually better than professional portraits with dramatic lighting, because the AI needs to see both sides of the face equally.
The generator blends the facial structure it can measure — eye spacing, nose shape, jawline, brow — so anything that hides or distorts those (a tilted head, a wide-angle selfie held too close, a beauty filter) feeds it wrong measurements. FaceCast shows you the result from two photos in seconds, so it is worth taking a clean pair before you start.
How to Take a Good Input Photo
Face a window in daylight
Even, soft light on both sides of the face. Turn off overhead lights so there are no colour casts.
Hold the phone at eye level, arm’s length
Closer than that, the lens widens the nose and shrinks the ears.
Look straight at the camera
Neutral or soft smile, mouth closed or lightly open, no tilt. Take five and pick the sharpest.
The Five Rules
Front-facing
Both eyes, both ears and the full jawline visible. Profile and three-quarter shots hide half the measurements.
Even light
Window daylight or overcast outdoors. Avoid harsh side light, backlight and flash.
Nothing on the face
No sunglasses, hats, masks or hair across the eyes. Ordinary glasses are usually fine if there is no glare.
No filters or heavy edits
Skin smoothing, face-slimming and eye-enlarging filters change the exact features the AI blends.
One person, recent, sharp
A single face in frame, taken in the last year or two, in focus at full resolution.
Why Results Vary Between Photos
Two photos of the same person can give visibly different babies if one is lit from the side or shot from below. The model is measuring proportions from pixels; change the angle and the proportions change with it. This is also why results from the same couple look consistent when both photos follow the rules.
A realistic result is a plausible blend, not a prediction. Genetics does not average parents, and no app can know which traits will express. Treat the output as a fun, well-founded portrait of a possible child.
Frequently Asked Questions
What kind of photo should I use for a baby generator?+
A recent, sharp, front-facing photo in even daylight with the whole face visible, no sunglasses or hats, no filters, and only one person in the frame. A window selfie at arm’s length is ideal.
Can I use a photo with glasses?+
Ordinary glasses are usually fine if there is no glare on the lenses. Sunglasses hide the eyes, which are the most important measurement, so remove them.
Why does my AI baby look nothing like us?+
Most often an input problem: a tilted or angled face, harsh lighting, a filter, or a photo taken too close. Retake both photos following the five rules and compare.
Does the photo quality matter more than the app?+
For realism, yes. A good app with poor inputs gives a poor result. Clean, front-facing photos in even light improve every generator, including FaceCast.
Are my photos safe in FaceCast?+
