With the announcement of the 2 new Canon DSLR’s with 50 megapixel sensors, a feeling of inadequacy has swept over many photographers. This didn’t happen when Nokia introduced their 41 megapixel cellphone for good reason. Cellphones don’t have large pixels, and large pixels are good pixels when it comes to low noise and dynamic range. You can put a lot of those big pixels on a full frame sensor, produce images that capture fine detail in large prints and still have low noise and a good dynamic range. Notice that the new full frame Canons with their high number of slightly smaller pixels do not reach the high ISO’s that are available with the current 5D Mark III.
(There is another important factor, how the manufacturer’s image processor does its job of dealing with sharpening, noise, e.t.c.. These days most everybody is doing a good job.)
Can you take advantage of these cameras? You’ll need very good lenses used at their best apertures, a tripod mounted camera or a very, very high shutter speed. You should probably bracket focus. For the kind of work I do, that’s silly. For the kind of work Edward Weston did, the only reason it would be silly is because he made small prints. The way galleries work these days, he would probably have to make big prints, and they would knock your socks off. For those of us who don’t normally do that kind of work, try putting your current camera on a tripod, setting the lens at f/5.6, using a low ISO and bracketing focus. Now make the biggest print your set up for. The results should be pretty impressive even when you press your nose against the print. Do you need even better? Would you like even better? What do think?
