    You used a shutter speed of 1/400 which pushed the ISO to 1250. I'm thinking a shutter speed of 1/125 would have been fine for this shot. A slower shutter speed would have allowed the ISO to drop considerably thereby reducing the amount of digital noise in the shot. The girl's face is also in shadow and shadows will show digital noise much sooner than the highlights will.

      Lower the ISO to max of 400 and use flash fill to light the face and see the difference
      I also have a D5300 like the OP.
      I remembered setting my max ISO the other day, but forgot what I used, so I just checked it and was surprised to find it at 12800.
      I thought this camera handled high ISO better, but I am early in the learning process.

      As a fellow newbie, the OP will want to know that these settings are only available in P, S, A and M modes.
      On any of the auto modes, this option is greyed out and I assume ISO reverts to full-range auto.

      I noticed on my D5300, when I set the max ISO to 400, the camera defaulted to a minimum shutter speed of 1/60.
      I felt that was a bit limiting, so I changed it to 1/40. Not that I have the steadiest hands in the world.

      BTW arsudarsan, here is the menu direction to all of this:
      Menu
      Shooting Menu
      ISO sensitivity settings
      [I assume] ISO sensitivity 100
      [I assume] ISO sensitivity control ON
      Maximum sensitivity 400
      Minimum shutter speed 1/60 [camera default]

      And yes, with more light on that beautiful Indian skin, the better your results.

      This is a wonderful forum with which to learn, and you will get much encouragement to leave the auto settings behind, and to study up (Google) on the exposure triangle (ISO, aperture and shutter speed).

      My D750 FX is the king of low light and ISO 12800 is a stretch for it. With the D5?00 series I really would not go over ISO 3200 and only then if I absolutely had to

      Setting at 1/40 is not going to do you any favors at all unless you are shooting with a wide angle lens or at the 18mm end of the kit lens. You will get motion blur to some extent and your shot will not be sharp. The OP was shooting at 200mm and with that camera hand held he will need to shoot at 1/300 sec to 1/500sec as a minimum. I am not sure on that camera but many of the newer models have in the AUTO ISO settings for shutter speed there is a auto setting there that will automatically know what length lens you have and even know what zoom setting and it will set the minimum shutter speed correctly based on the length lens. This feature will save you a lot of grief when shooting.

      Re: Couple of shots with first DSLR

      Thanks Don.
      I am remembering from my film days.
      I shot mostly ASA 400 and 1/60 was about the minimum.
      I only had two lenses back then (mid 70s), the 58mm f1.4 that came with the SRT101 and a Vivitar 85-205 (f3.8!).

      I know with that fast prime lens, and no built-in flash, (and young, steady hands leaning against a wall), I was able to use 1/30 often.
      But of course, digital is not the same as film, and the best I can do with my 18-55mm kit lens at 35mm is f4! That probably explains the affordability of this particular lens.

      I can't wait to start this new job tomorrow and begin saving for a decent 35mm prime.

      Thanks for some good insights on the graining. I did check a few other shots that I had taken with better light. The graining effect was much lesser. Another one shot in the park.
