@jpFoto......Will Under exposure make the difference?
Under exposing an image will not affect your focus, however, it does affect your overall image quality. It's not my place to tell you how to shoot or setup your camera, but since you have noted here and in your other thread that you are disappointed with your D3200, and would like some suggestions, I would suggest a few things.
First, you haven't posted very many images, but a few of the ones that you did post were taken in low light with high shutter speeds, low ISO and wide open; some with flash and some without; and all with custom white balance. You also have chosen manual mode in at least one of your portraits. I think that these settings are a blueprint for disaster. Until you feel comfortable with your camera, manual mode probably isn't a good choice. Also, most built-in flashes do not produce good results used as the primary lighting solution.
Second, I have my camera set up as follows and you may want to try a similar setup until you are comfortable with the camera and have experienced some success:
1. Auto White Balance.
2. Auto ISO Sensitivity ON - ISO 100 - Maximum sensitivity 6400 - Minium shutter speed 1/125. (You may want to set your Maximum sensitivity to 1600, particularly if you are shooting jpegs only).
3. I use A (aperture priority) most of the time, but you may want to try using P (programmed auto) until you are comfortable with the camera. I would avoid using AUTO, (the one in green.)
Brian's suggestions for your focus settings make very good sense for portraits and other relatively stationary subject.
You may also want to pick a copy of Bryan Peterson's, "Understanding Exposure." Here's a link:
