jpzk, I am definetely not the right person to explain the differences between "Bicubic Sharper", "Lanczoz3" and all the other algorithms . But out of experiences I have learned that "Bicubic /Bicubic Sharper" gives a better result than the default "Lanczoz3" when I reduce the image size - for web etc. Expecially for portraits and similar soft images. "B.Sharper" takes better care of all the details.
But this is not the case if you are an architect student and most of the lines are stright. Or if your picture already has been sharpened.
Photoshops default algorithm when you select File> Save for Web> is "Bicubic" . I am not 100% sure but I think Bicubic = Bicubic Sharper when you reduce the size.
