In my recent post about high-resolution cameras, I stressed the importance of sharp lenses to get the most out of these 36+ megapixel sensors. But lens sharpness is an issue with any camera – at least when you start making larger prints. Even with a 16- or 20-megapixel sensor, lenses make a significant difference in large prints (16×20 inches and up). This is especially true in the corners; most professional-quality lenses are sharp enough in the center (at least with middle apertures like f/8 or f/11) for even a 36-megapixel camera. It’s the corners and edges that separate the decent lenses from the great ones. Those great ones are hard to find, and tend to be expensive.
Wouldn’t it be nice if you could fix imperfect lenses with software? Well yes, of course. But my experience with such fixes hasn’t been good. I’ve seen some great before-and-after examples online showing a blurry photo fixed with software, but when I’ve tried those programs myself I’ve invariably been disappointed. These cures tend to be just more-sophisticated sharpening methods, which may help a little, but if you apply more than a small amount things get really crunchy, or you see other weird artifacts. I can usually do just as well by selectively adding more sharpening to the corners in Lightroom or Adobe Camera Raw.
A few months ago I stumbled across another program that promised to help with fuzzy images, called Piccure+. I decided to download the free trial, and found that it worked surprisingly well. It’s not a magic bullet; there’s really no substitute for sharp lenses. But it can help with those soft corners, or overall softness caused by diffraction. Like any of these tools, it will definitely make the image look too crunchy if you overdo it, but I’ve been able to push the sharpening effect further in Piccure+ than with other software I’ve used, with good results and minimal artifacts.
