    It doesn't appear particularly grainy or noisy on my screen, however there is some smoothing of detail in the shadows so maybe the camera applies a fair amount of noise reduction in iauto mode. Matters cannot be helped by a very low file size of 180kb for a 2000 x 1500 pixel image. The main problem with this picture is that it is severely under exposed - try to lighten it and I suspect you really will see some noise then! I would avoid iauto as it limits much of the control you have.

        I think you will learn more as a beginner by using your own judgement of exposure, based on the image shown in your E-M5 viewfinder.



        Auto modes can work in ordinary mid-day conditions but when you try something more interesting, you need to make your own judgement and explore the effects of taking several shots at different exposures and then choosing the best.



        Digital cameras are great for learning, because you can see all the exposure data and learn what settings do and do not work. Then simply delete the poor ones.



        Good luck.

          Noise/grain is not just iso based, image/PP/exposure and intended presentation form are all relevant.

              What you will do with the finished product, if its on a forum and you think the noise is a problem keep the size down to 1024 on the long side, noise will still be there but not so much in your face.
              An example at iso 5000, noise is still present but it would be a lot more obvious in a larger print.

                Grain is also less noticeable in a print, because the ink dots merge slightly.
