Dear Giovanni,
    You have raised an interesting point with your photo comparisons. I see hardly any difference in quality!
    But I have a question (because I have never really understood how to control this). I use a photo management program called ACDsee. With this I can change the size of an image. But when I resize, all it does is reduce the number of pixels (and the kB goes down in same proportion). For example, if I want to reduce an image which is 3200 x 2400 to 25% of its original size, I can make it 800 x 600. And it will be 25% of its original kB size.
    However, when I look at your examples I see that you have managed to create 2 images, both 800 x 1105 pixels, but with 2 different file sizes (599kB and 59kB). How do you change the file size while keeping the pixel count the same?
    This must sound like a silly question to ask, but I have never understood how to control kB size!

Regards,
Tom
