This JPEG issue has become ridicolous, and I'm starting to think
that all those who say that the camera is "designed" to provide
"film like", "natural" images are saying it just so that they can
feel better.
Pentax own designers are saying it. The reason for this is that Natural image tone works best when you post process images. I have learned digital photography workflow, and my teacher said it is best to sharpen the images as the last thing one does - if one wants quality.
If you sharpen the images in the camera first, and then resize, and then sharpen again you will loose detail. When you post process, you don't want upsharpening in the camera.
The Natural image tone was designed for those who post process their images.
Pentax own designers, like Mr Tatamiya (project coordinator of the K10D), says this.
So we haven't invented this in order to "feel better".
This comes directly from Pentax own engineers.
If you want oversharpened images, as many seems to like (but I hate them), then switch the camera to Bright image tone. Natural image tone concentrates on texture and details, Bright image tone sharpens the edges more.
The sharpness, saturation and contrast sliders do work in the Bright image mode.
(they don't on the DS). So, if you find the colours too much you can always tune down the colours, but keeping the upsharpening of the edges.
So I don't understand what Pentax should fix...
My experience with the K10D's images taken in Natural image tone, is that they are clearly more detailed with more depth and texture than images taken in Natural image tone on my *ist DS.
Take care
