The DC4800 offers two different colour modes, "Saturated" and "Neutral" which gives you fairly good control over the saturation output of the cameras internal processing algorithms. On top of this there are also four black and white modes (designed to simulate different types of black and white film).
|Colour: Saturated||Colour: Neutral|
|Colour: Black & White||Colour: Black & White (Y Filter)|
|Colour: Black & White (R Filter)||Colour: Sepia|
Three levels of sharpening, none of which really solve the artifacts problem, though obviously sticking to Standard or Soft will reduce their visibility.
Readers of my reviews will know I'm not a huge fan of digital zoom as it's often a badly implemented and seldom used (by owners) marketing "ploy" to sell cameras which don't have an optical zoom. The DC4800 has a 3.0 x optical zoom, and a smooth digital zoom up to 2.0x, you can choose for this to be a continuous zoom after the optical zoom, for there to be a pause before going into digital zoom or disable digital zoom altogether.
Digital Zoom is simply cropping (selecting the mid part of the image) and sampling-up, the only advantage in doing digital zoom inside the camera is (a) if you don't have any photo software to magnify (and interpolate) the image or (b) to digitally zoom without zooming the JPEG artifacts.
