none of those pictures appear edited to me, the hardest part is to learn how to use your camera and its features to your advantage.
the best way, is to get out and and take ALOT of pictures, all of the ones i have posted were taken at least 5 months after i had the camera, and i would go out taking pics about 3 times a week for a few hours each time, it took me a long time to start taking pictures i was actually proud of because i had learned how to get the image i was looking for.
results like mine and pipens should be easily attainable with your camera once you have spent enough time with it.
EDIT: just thought i would mention that none of mine are edited, they are all right out of my camera.
also, im working on a guide (have been for a little bit of time now) on how to get the shot you want, basically walking through what camera settings are essential and how to use them, hope you guys will take a look once im done
