    A few more with that freebee Image Analyzer I referred to (quite the swiss army knife, really!), using the sample image, enlarged 800%

    Wiener 4:

    Two of the fractals (no idea what the parameters do just playing). I got the best results by going x2, x2, x2 rather than straight (the image names include the parameters):
    resize_Temp x2 region=7 regul=0 x2 region=7 regul=0 x2 region=7 regul=0.png
    resize_Temp x2 region=9 regul=0 x2 region=9 regul=0 x2 region=9 regul=0.png

    And two more from Gimp - progressive resize, 800% in 20 steps:
    gimp_resize_steps.png

    and a gimp plugin "smart enlarge" using resyntherizer(?) I enlarged 2x 2x 2x. The first was OK, but after that it certainly added detail, but bolloxed up the image:

    And for your viewing pleasure, the gimp resynth plugin going the full 800% in one shot Not a good resize, but an interesting 70's acid trip none the less:

    And here is the best I could do with some playing.

    This was done with Image Analyzer fractal resize x 2 then a wiener resize x2, followed by a fractal resize x2. Pulled into gimp and added film grain.

    Thanks Mathuwm and Rob for those. I like that Genuine Fractals one. I would agree that it is the best of them all. Its artificially sharpened up those edges just where it was required. That really is some clever software there.

    In this thread I was talking about antialiasing and how occasionally you see the spokes of the wheels of a western movie wagon go backwards or sometimes even look stationary because the camera frame rate is similar to the action. Well I cam across this today - you will have to forgive the title of this movie but I have never seen a better example of temporal antialiasing - ever. Its excellent !

    Dead horse beating time...

    I think I just found the best free enlarger out there:

    http://imageenlarger.sourceforge.net/

    Here are some samples of the little image enlarged to 800% with the 4 enlarging presets (all png to avoid jpg artifacts):
    Default:
    Temp_smilla_default.png

    Sharp:
    Temp_smilla_sharp.png

    Painted:
    Temp_smilla_painted.png

    Sharp and Noisy:

    And as a special treat, a jpeg of the samesource image blown up with the default setings to 3000%:
