After playing around with this a lot over the past week or so, I am not convinced that Bicubic Sharper is ~better~ than Bicubic, they just afford different results. It's quite possible - it seemst to be true based on the number of images I've experimented with - some images lend themselves to Sharper better than others. The problem with Sharper is that the user has no control over the results unless using other techniques, such as multiple layers.

It seems that if one starts with a nice sharp, high-res image, it's hard to wreck it by making it smaller. I had to downsize some 72 meg tiffs for web use this weekend. I tried doing it with Bicubic, Bicubic Smoother, and Bicubic Sharper. The three resulting jpegs (13 inches on the long side, 72dpi) were identical to my eye, even when wearing my glasses :-). But since the consensus appears to be that Bicubic Sharper is better for downsizing, I'll continue to use it, while using Bicubic Smoother for upsizing. > Paul > > > > Hi, > > > > When the file size is reduced in one step, using Bicubic or Bicubic > > Sharper, there is no mushiness.
