Looks like paramount lighting on the subjects, with vibrance to enhance color other than skin. The lighting and post processing on the subjects is reminiscent of the "Dave Hill" or "Jill Greenberg" lighting and processing style, that was popular about 20 yrs ago.

The shot does not look like a composite, since the ground directly underneath the models "fits in" with the general depth of field and background focus decay that one would expect.

Interesting. You have customers who want a photo like the one you posted and so you come here and ask how it was done so you can get EXACTLY the same result.
Well my friend, it is called EXPERIENCE, SKILL, HARD WORK, DEDICATION, EDUCATION, and PRESERVERENCE.
You should try it. That is how I developed a style in wedding photography that sold itself.

Easy to do. You can saturate the hell out of the entire pic and then go back with a simple brush and fix skin.

To answer your question, probably Photoshop with aforementioned adjustments
Good luck!

It is done with Green screen it is done all the time right down to the shadows .There is a great availability of themes from Disney settings ,and distant locations around the world....My employer used to do Disney princesses we supplied the dresses Green screen supplied the location a little lighting and Every girl could be Cinderella...They even have scenes for babies and young children fishing playing in a tub swinging in a swing ,unbelievable amount of themes . Turnkey editing by the software...CHROMA KEY

So do mine, probably shot at F 2.8. Maybe blurring the background somewhat. Did you see the comment by the person who was out raged at the feet were cut off?That person needs to learn something that composition or be put into a mental institution.

Agree, I don't consider that picture to be particularly good.

No filter.

Fill flash was used.

Saturation was boosted.... possibly selectively to "protect" skin tones.... but it's hard to say.

I don't know for certain that this is a composite or a background was dropped in, such as would have been done if a green screen were used. I suspect it was shot on location because near the bottom of the image flash appears to be illuminating the grass and stones, yet it's not illuminating more distant parts of the scene. It would be difficult to match the lighting of a dropped in background.

I agree with other observations about the background and composition. It's a pretty busy and poor choice of a background to add to an image, if that's what was done. The photographer also should have either shot a tighter crop, such as the head and torso of the young ladies... for more close-up detail. Or, the photog should have backed off to get a full length shot to avoid cropping off their feet. Alternatively, rotating the camera to portrait orientation probably would have kept from amputating their feet, too.

It's a low res image but if you save it and magnify it, the catchlights are there.

Given the light I doubt it was fill flash. There seems to be only one light, slightly above the camera from the same position of the camera, which is why I suspected paramount lighting, or maybe butterfly lighting. As you pointed out the lighting on the grass is also consistent with the one light/one take idea.

As far as the feet is concerned, maybe their feet were dirty, or just plain ugly feet.

IMHO, this is a composite photo and not what I would aspire to produce as a portrait. I see the background as not in scale to the girls and a distracting color element. Cutting of the feet, as mentioned, and the lean to the right in the pose don't help the photo.

Rave reviews? really? It's a composite image and not even a very good one.
Look closely ang compare the size of the grass and pebbles to the 2 persons.

The 2 persons seems to be photographed with a flash and the background is a different photo.

Its also possible that two were standing in front of a background that is a big print of another photo so the photographer had to cut the feet off.
