i dont understand why this one is not grainy at all
Hello Vanessa. Well the 2 photos that you are comparing were taken using very different variables. I will summarize them based on the EXIF:
| First Photo | Second Photo |
ISO | 400 | 200 |
Shutter Speed | 1/25 | 1/60 |
Flash Fired? | NO | YES |
Focal Length | 52mm | 24mm |
The first image was blurry and out of focus due to the slow shutter speed and perhaps less than ideal hand holding technique. So you have the first photo, with no flash, slow shutter speed/longer FL and higher ISO on a camera not renowned for it's higher ISO performance (not that 400 is really all that high but it is noticeably higher than ISO 200).
The second picture is in focus, no blurring due to camera shake, an adequate shutter speed (but still could have been higher), a lower ISO, etc. Hence a better photo!
In the first photo it looks overexposed due to you, perhaps, bumping up the exposure comp. a bit too much in post-processing. When you pull up darker area too much in post you will get grain. The second photo is much better in terms of the exposure - again lending to a superior image.
