How to configure the FujiFilm X-T30 to take a selfie while holding a baby?

If the baby is out of focus because it is moving around too much, you can compensate by increasing the shutter speed. Using a tripod and the self timer may also be helpful.

If the baby is out of focus because it is not within the depth of field, you can increase DOF by:

• Increasing the distance between subject and camera.
• Decreasing the focal length of the lens.
• Stopping down the aperture (by using a larger F-number).

For a selfie, the only factor you have much control over is the aperture. Start with the largest aperture (smallest F-number), and take test shots after stopping down (increasing F-numbers). Usually, the value changes in 1/3-stop increments, so to limit the number of test shots, increase the F-number three times between each shot. The standard sequence is: 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22.

Note: If you set everything to Auto, except for one setting, the camera will automatically adjust them for you. So while it isn't fully auto, it may be close enough.
