I want a way to know what camera produced this beautiful photo. I shot a photo in the same place with my Nikon D3200, but it was not close to the quality of the other shots. I believe that could be an iPhone camera for the contrast in the images, but I am not sure.
Normally one looks ar EXIF information to see which camera make and model took a photo. There is also almost always information regarding the lens used too. If you use legacy lenses or an adapter it is unlikely the information is there though.
What you linked to is not a photo, it's a composite image and might even be made with images from different cameras. Even if the same camera was used, it could be still different lenses. Unless you got something closer to the source, there is no sure way to know.
That being said, if your Nikon D3200 is not giving you a good shot, there are a lot of things to blame before the camera. The main difference you show is the light. I would say it makes all the difference here. You shot on an overcast day, their top shot is shot under sunny conditions. The bottom to shots are also taken on overcast days, in which case it could be the lens or simply your configuration. By default many DSLRs like the D3200 have somewhat soft and and low contrast tonality. You should adjust setting to your liking, it is in the camera menu under Picture Control. A good lens makes very good difference in terms of sharpness, contrast and flare.
The bad news is, and I do not mean to be rude, there is a little problem with the device holding the camera. Xo)
The image you linked as an example has nothing special in terms of light. (On a landscape you have to live with what you have, unless you can spend some days returning to that location in different weather conditions and hours of the day)
Compose the image
But it has a decent framing, and that is all about two things:
Move around and see.
When you are on an interesting spot, move the camera and frame.
I do not know if you gave up taking just one shot of what was in front of you or you put some effort to move around watching the surroundings.
Your photo has no point of interest, has no composition, you need to work on that. Move, take a photo laying down, move one step to the left or to the right, force a perspective, take different planes at the same time... COMPOSE the image.
Here is a post about composition: My attention gets repeatedly distracted by the elements needed for the context in this picture. Where am I going wrong? Explore that tag on this site. https://photo.stackexchange.com/questions/tagged/composition
Remove the people
Take several shots, using a tripod, across several minutes and then use the "no people" zones to composite a clean image.
Regarding the camera taking the other images... It really does not matter. In Youtube there is a really funny "Pro Photographer, Cheap Camera Challenge" of a DigitalRev channel
Look for example this:
