In my opinion this is one of the best photos my group took. Direct light is applied in this photo and brings out dark shadows. The egg is sidelit which is why we can see the shadow which the egg cast to the side of it. With the shallow depth of field we get an image that is sharp overall. The eye-level viewpoint also reveals the inside of the egg because of the light.
The light here is between backlight and side light. The shadow is coming forward to some degree so it isn’t just side light.
In a tabletop photo, shot in a few feet, to say that everything is sharp because there is extensive depth of field is literally true but not meaningful. the subjects need to be at a range of distances from near to far from the camera to make this a relevant attribute of a photo.
