At the image below, both of them are not in focus. If you look closely, in the top image you can see that focus fell on his shirt. That is the most clear part of the image. His eyes and his face (what you normally want in focus) is blurry and out of focus. The bottom image is also out of focus. This one is because of a too low shutter speed and there is motion blur. Images can also be out of focus because of a camera error. Your photographer should cull all those images and not present them to you.
When scheduling the session the earlier the better. Newborns much younger tend to do very well in the studio, oppose to a baby that is 10-14 days old. They tend not to wake up frequently and as easily when getting them posed for the scene. A mere 48 hours in a newborns life is very crucial when prepping them for their session. I have witness many, many times after the 10 day mark, newborns have discovered the art of stretching! Once that happens…they won’t let us curl them up in the cute little newborn poses, without a fight!
There are a few bonuses to using accessories well (as well as layers). One is that changing them up a bit throughout the session can give you multiple looks without having to do many wardrobe changes. They can also be something that the subjects can interact with. A sassy little tip of the hat, holding the ends of a scarf while running and letting it billow behind you, grabbing the lapels of a husbands jacket while pulling him close for a kiss – all these little gestures and ways to interact (and become more comfortable in front of the camera) can be made possible with styling choices. Many of my sessions will feature items used outside their intended use or subject. My girls are often seen in mommy’s hats or scarves (scarves can be used in different ways like wrapped around their shoulders, as a hair piece, etc) and they love to wear my costume jewelry.
