Make sure that the light conditions are good. You may be using a flash but it still may not be adequate. It is best that you have another source of light. However, do make sure that the source does not cause the pictures to be overexposed as it is easier to fix underexposed pictures in comparison with overexposed pictures.
Many people prefer to have the baby in a diaper only but it is not a bad idea if you take the picture with some cute looking newborn clothes. This will make the pictures look different and with the right choice of clothing, the picture can look even more fantastic. However, if you are old school and do not want to break away from the norm, you can take the picture of the baby without clothes.
There are many ways in which the pictures can be taken and you can achieve much by getting your imagination to work. You are likely going to come up with some brilliant ideas. You can also use some tried and tested ideas in order to get some pictures that look great. However, these will not be unique and will not be imaginative.
Not only can you experiment with the way the pictures are taken but you can also play around with colours. You can take them in black and white or keep them in colour.
You can edit the pictures in order to correct any flaws that may have been left. These could be related to the light or due to some unexpected object that was captured in the picture. Once these are corrected, you should have an excellent picture of your newborn that should always remind you of that special time.
