Hi stMoritzer,
I already had an idea of what the prob was before I took a look at one of your pics
If I were you, I wouldn't turn to other photo editing software that fast. Your pictures are grainy, that's for sure. I link that to the iso/asa setting of your camera. According you are using a very nice camera I won't blame the camera either
I mean, I don't think there is something wrong with your shooter.
The example images you have posted above are made with very nice weather condition... lots and lots of light. just check what the iso/asa setting was during that session. It looks like it was set at 600-800, when you combine that with a very high shutterspeed you get those grainy images.
My advise is:
- Check you Iso setting, you should use 100 or 200.
- Further on I want to advise you to step away from shooting with very high shutter speeds. Why would you shoot at ... lets say 1/300 ? No need for that, just go for shutterspeeds around 1/30 - 1/80. The result will be completely different. You will end up with brightly lit pictures full of detail !!! There are lots of peeps who are afraid, when using low shutterspeeds, to end up with blurry images. To be honest, I don't understand how it is possible ending up with an unsharp picture when the object you snap isn't moving.
The first thing I did after I had bought my D70 (my first SLR) was checking the manual just to figger out which program would suit me the most.
Let me know what you think of it ! You may always send me a pm as well.
Good Luck
Cheers
