  2. Hi Andreas - they look good; sharp and with no sign of purple fringing. No
    evident noise either, though if course your samples are small compared to
    the original and you only went as high as ISO 200.

    Come on you guys - if you're going to post samples from a camera,
    include at least a couple of full size images.

    I did enjoy them, thanks!

    The Abendnebel has only partial-histogram green and blue channels,
    though the red channel is full. I ran Levels to stretch GB histograms
    and thought it improved the image, though it was perhaps too blue.

    All outdoor images seemed too red and/or attenuated in the blue channel.
    OTOH the image of two cooks against a red background seemed too cool.
    Don't know how you downsampled, so I won't comment on sharpness or bokeh,
    which doesn't seem very good.

    It was already quite dark, few seconds before sunset and I didn't check the
    settings carefully ;-)

    That's normal here this time of day, short before sunset with snowy white
    ground.

    Used Photoshop to downsample bicubic. Do you have a recommandation how to
    improve quality?

    Nice pics, why is the EXIF info so limited?

    Thanks Andy, wonder what all that maker notes means, looks
    like a bunch of hexadecimal code.

    As Bart van der Wolf has shown, the Lanczos filter (as in ImageMagick)
    downsamples much better than Photoshop bicubic sharper. The bicubic
    algorithm is perhaps more versatile than Lancsos, especially when changing
    the ratio of x/y dimensions (aspect ratio). Here is the ImageMagic command
    I use for 20% downsampling:

    convert -filter Lanczos -scale 25% -unsharp 1x3+1+.09 in.bmp out.jpg

    That results in quality 75 JPEG, which could be increased with the -quality
    option. If you increase quality > 85, -sampling_factor 1x1 is recommended
    for 4:4:4 chroma subsampling. Here is Bart's website:

    That should be "-scale 20%", sorry.
