This was with a second hand Nikon D50, 6 MP.
A 30mm Sigma DX lens.
I made them in Raw and adjusted the white balance and contrast etc...
I did no crop on the photos, only added a little vignetting.
Furthermore no photoshop.
I used a mini tripod, aperture at f16, iso 200.
Shuttertime was set automatic, don't know how long it was, around 2 seconds?
