Digital camera makers continue to squeeze ever more megapixels into their products. But does that make for better pictures? Some experts say no. Image quality isn’t improving, they say, and some fear it may actually be degrading as the megapixel race escalates. The basic concern is that smaller pixels on camera sensors means less sensitivity to light, leading to image noise such as off-color speckles or rough edges, worse performance in dim conditions, and the loss of finer tonal gradations such as the subtle shadows of a white wedding dress. Point-and-shoot cameras, with their small sensors, are the chief culprits.
I don’t think anyone can use a new 10MP point-and-shoot camera and exclaim great quality. Some have better than others, but unless you have a DSLR, anything above 6MP is going to appear blotchy or have lots of noise. I’m a believer of Quality > Quantity, but I think having a point-and-shoot camera that takes “great” photos at 6MP would be a win.
