Camera Settings
Professional photographers know how to adjust their camera's settings such as exposure, ISO and aperture to achieve the best possible photo. For an amateur who doesn't understand these functions or doesn't have control over them on their camera, it's not as easy. Digital cameras do allow the settings to be adjusted. Most cameras have an aperture priority setting, which is generally ideal, unless the shutter speed is too high and the photos look blurry, in which case it's better to switch to shutter priority mode.
Positioning
Before attempting to take photos, the best possible position should be found in regard to available light. Window photos are flattering, provided the sun isn't shining directly into the window. Placing the infant with the sun at its back will reduce facial shadows and eye squinting.
Weather and Time
The weather and time of day have a major impact on the natural lighting available for a photo. The ideal weather for a photo shoot, especially an outdoor shoot, is cloudy. On a sunny day, try for shots when the sun slips behind a cloud. If at all possible, avoid taking photos in the middle of the day, when the sun is strongest. Morning light is the most soft and flattering.
Diffusion and Reflection
Another technique professional photographers use to achieve high quality photos is to direct the light to where they want it. A thin white sheet can be used to diffuse the bright light and give the photo a softer look. Panels can be bought to reflect the light to where it's needed and reduce harsh shadows in the photo. It's helpful to have an assistant direct the light while taking the photos.
