Yea, getting just a few inches away from a fly is not likely to happen in "the real world" and much of great photography is a studio shot. Lots of "nature" photography is done in an studio setting with fancy lights, and cameras on rails or mechanisms that are remote controlled.
Food photography is the same way. If you go to a restaurant and open the menu and the food photos look wonderful, it is a studio photo with a food stylist and special lighting. If the photos looks like a Facebook photo with one flash lighting, it is not a studio photo. I have helped on foot photos jobs that cost many thousands to get a perfect shot of a meal.
We went on vacation for a week and a squirrel decided to find out how many black walnuts they could fit in my engine compartment.
The answer is 558 walnuts. 558 black walnuts fit in my engine compartment.
