I live in the north-east part of the country, far away from the famous Roma, Naples or Sicily!
However, I live in the middle of the beautifuls Dolomites mountains, so not too much pizza&mandolino pics from me I guess, instead you can have a lot of mountain's landscapes if you like it :D

The technique of photo stacking is another thing. We are discussing about the pixel shifting! Trying to emulate the apposite feature of the K-3II and K-1

Hi observer, i'm very interested about this possibility. I think that even the K-5 has the hardware capability to manage the sensor in order to properly expose every RGB color and get full colour information for every pixel. Of course i don't think that Pentax has interest to retro-support this feature on older models.
I think that praticing the composition adjustment way is the only chance to achieve this.
Now, the side of a single pixel in this sensor is about 4.8µm (height of the pixel=height of the sensor/pixels of the short side=15.6mm/3264; width of the pixel=width of the sensor/pixels of the long side=23.6mm/4928). The composition adjustment shifts the sensor for a maximum of 1,4mm on each direction; it has 24 steps. This means that every step shifts the sensor of 0,06mm, or 60µm, so 12,5 pixels. To reach a full number, two steps mean 25 pixels, and as long it is an odd number, this will work to reach every RGB color. With a loss of -i guess- about less than half-million pixels, we can achieve the sharpness and the level of details of a Foveon sensor, even if there's no place for motion in the scene.
Every information or contribute about this project will be helpful!

And...sorry for my english, of course :lol:
