Here's my attempt to help.
In the first example, the sentence
She enjoys being photographed
tells us that the person enjoys having her photo taken.
What does this sentence mean? It means whenever someone takes a picture of her, she is pleased, and does not feel embarrassed or bored by this simple activity. She doesn't mind posing in front of the camera. In fact, she likes to have her photo taken.
This exemplifies the use of the present simple tense, the present simple is used to convey something which is either a fact, or an action that is habitual. Instead, if she regularly uploaded images that she took of herself, we might say:
She enjoys taking selfies
With verbs of preferences, e.g. like, love, enjoy, don't mind, etc. it is common to use the present simple tense. We do not normally say
She is enjoying being photographed
While the construction is not forbidden, it is acceptable in speech and in most English dialects, it seems to have a slightly different meaning from the original; here the subject is currently experiencing enjoyment while someone is taking two or more photos of her. The subject could be a child who is happy and excited that she is photographed on her birthday.
If we wanted to refer to this ‘enjoyment’ in the Past Simple tense we would say
She enjoyed having her photo taken (at the party).
She enjoyed being photographed
to express future meaning we might say
She is going to enjoy having her photo taken
She is going to enjoy being photographed
She will enjoy having her photo taken
She will enjoy being photographed.
One last point, although it is grammatical to use either the infinitive or the gerund after the verb like
She likes to be photographed
She likes being photographed
The same is not true for the verb enjoy, it is best to avoid the infinitive after the verb enjoy.
She enjoys to be photographed. NO
