How can the visual elements in a photograph help a viewer read and determine a photographs narrative

We spend a lot of time thinking about how to make and take a photograph, but we may not be as thorough when thinking about how to view a finished photograph. With the exception of studying photography as fine art, we typically approach a photograph as a technically accurate representation of what the photographer saw. A subject is a subject is a subject, to paraphrase Gertrude Stein. And in all fairness, some photographs—snapshots and pics, really—are not meant to be more than tangible items that remind us of what we saw or experienced. Quick pics of a restaurant meal, selfies, and snapshots taken at events often fall into this category.  

Explanation:

covert: hidden or secret

candid: truthful and straightforward

what i get from these phrases is covert means undercover or underground and that's where the flower is in april. on the other hand, may is the month where flowers start to bloom and thats the reason why candid is being used as a word to describe the blossoming period of a flower.

hope this answer you.
