What with stitching and 20+ megapixel backs, sometimes you have to res an image down to print it. I tested all four algorithms on a 480 ppi image resampled down to 360 ppi. Instead of using bicubic smoother in Photoshop, I used bicubic sharper, which Adobe recommends for down-resing. The results: Photoshop Bicubic Sharper (above)… [Read More]

Another cloud disadvantage is… Performance. Cloud implementations have one strike against them from the get-go; with a few exceptions, they can’t possibly feel as crisp as their all-desktop equivalents because of network latency and bandwidth issues. Accessing your Exchange account through a browser provides an experience that looks remarkably like Outlook, but the performance is… [Read More]
