(Note: Old version of MacBeth chart, hence slightly different aspect ratio. Also, its color space is NTSC, hence looks odd here (not converted to sRGB for web display) |

Our "House" poster has a lot of very fine detail in it, so is a handy tool for comparing camera resolution on *exactly* the same subject. (It was shot with a 4x5 view camera with a razor-sharp lens, scanned to a 500 MB file, then output on a 600 dpi photograpic output device at a size of about 40x50.) Comparing natural images like this is a little tricky with cameras having different file sizes. We've scaled the images to match the horizontal dimension of the largest of the set, using bicubic interpolation in Photoshop. The results are interesting, to say the least: The 3 megapixel D30 does amazingly well. It's important to note though, that the D1x produces considerably better results when shots are saved in the NEF format, and then interpolated after the fact on the computer. We'll try to do a reshoot of this later this week, and share those results here.

(Shot with normal sharpening, etc. Sharpening is a little heavy-handed in this image, obscuring some detail. Better would be to shoot in NEF mode with no sharpening, use Qimage or Bibble to extract maximum-res file. - Even at that though, we're surprised the D1x didn't look sharper here - we'll try reshooting this as we suggested, see what it looks like.) |
(Quite a bit of detail despite substantial resampling required to match the size of the 6 megapixel files. Really amazingly good, considering it's a 3MP sensor!) |

(Competes quite well for a 4MP CCD.) |
(Also does well for what's basically a 3 MP sensor, upsampled to 6MP) |
Not much comment needed on this one - these are just crops from the ISO-12233 resolution target. The only note we have is that these were tone-adjusted in Photoshop, to prevent differences in brightness/contrast from swaying people's perception of the images.

The vertical-axis res target elements. Same note as above, vis a vis the tonal adjustment.

Interesting, eh? No doubt about it, these are some fun times in the photo business!
