Explain each. Resolution is the distance between two objects in which the objects can still be seen as separate. A poor resulution will result to two or more objects appearing as one Contrast is the difference in light absorbance between two objects. Whe there is poor contrast, it results to a high bacground and makes visualization difficult because you are unable to contrast between the background and the object you are observing. For example poor contrast is illustrated by looking at two dark objects in the dark which makes it difficult unlike looking at dark coloured objects in bright sunlight; this is a good contrast Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor or low resolution means two (or more) objects may appear as one. Contrast is the difference in light absorbance between two objects. Poor contrast gives a high background and makes the visualization of multiple objects difficult. For instance, trying to identify 2 dark colored objects at night (low light = low contrast) versus the same 2 objects in the middle of a sunny afternoon (bright light against 2 dark objects = high contrast).
