As the name implies its composition<br>consists primarily of essential &#8216;ingredients&#8217; such as a rich source of sugars, amino acids and<br>vitamins.

Resolution refers to the distance between two objects at which the objects still can be<br>seen as separate. Poor or low resolution means two (or more) objects may appear as one. The<br>contrast is the difference in light absorbance between two objects. Poor contrast gives a high<br>background and makes the visualization of multiple objects difficult.
