I thought, it's time to post couple of photos to receive
constructive critisism and comments.
I normally do not use much post processing (I like naturality of nature photos), but I have used in-camera settings to get colours more vibrant in some of the samples.
This first one was one of the first photos I took with my newly arrived K-7.
It's also the only one with a little post processing (noise reduction).
This one shows clay layer deposits in some ancient fond of sea.
The final two are macro samples from my carden.
Enjoy (if possible)!
