My nikon d3200 takes foggy pictures?

The top photo is how my Nikon d3200 takes the pictures… (foggy and grey) and the bottom is how they should look! Please Help! WHAT's WRONG!

The lower picture looks a bit too saturated for my liking, I actually prefer the upper one, the slight under-exposure working to advantage in this case.

From the leaf at the top right, I'd suggest that the lower picture was taken at higher aperture, allowing in more light but blurring the leaf.

Work on your exposure settings. Exposure meters can be fooled, and there's no substitute for hard experience.

Set the picture control in the menu to Vivid for shots like that, or manually add contrast and saturation to suit. Better still put more light (and directional light) on the subject so that you get modelling rather than an overall flat look.

In the top exposure the white flower has fooled the camera exposure meter into underexposing the image. It needs another 2/3rd to 1 stop of exposure and the colour saturation upping a little.

The bottom image is horrible. The colours are grossly over saturated and look unnatural.

Do you happen to wear eyeglasses or contact lenses? If you are focussing manually, you must remove them or you are simply focussing to your prescription.

The not-so-great focus could be caused by moving a non-macro lens too close, and/or doing manual focus not very well, and/or failing to place the right auto-focus sensor right on the pistils, and/or hand-held camera shake.

The pictures are the same shot, but with the second version having some software tweaking of white balance, contrast, sharpening, and saturation. It looks a bit over-cooked. Probably an automatic image correcting setting in the program, which can sometimes overdo things. Some of the camera settings can be tweaked for a more vibrant looking image straight out of the camera. Nikon tends to be a bit dull by default. That is not necessarily bad, because it provides more latitude for software tweaking.
Using a white card and custom white balance setting could have been a good idea, with this scene being too challenging for auto white balance to really get right.

You didn't say if you are using Auto mode, or some manual mode. It appears that exposure, saturation, and maybe white balance are off -- possibly caused by incorrect manual settings. Maybe try going into your Menu and resetting everything back to factory settings. Then try Auto mode to see if you get better results.
