DSLR and P&S Smackdown
This might be fun. Yesterday, I took two pictures. One with a Canon SD890IS
and a second with a Nikon D300 with the Nikon 18-200 mm zoom. I've posted them at: http://www.classtech.com/DSLR_PS_Smackdown/ The question is "Which camera took which picture?" and "Why do you think so?" They are labeled "A" and "B" for purposes of discussion. I'll post the answer when the discussion dies down. The picture isn't much, just a shot of a Mc Mansion being built. But there is lots of detail and texture. Navigation help: You can click on a thumbnail to get a medium resolution view. Then you can get a full resolution view by clicking in the lower center of the picture or the download icon in the lower right of the screen. Methodology comments: I took the two pictures from the same spot within a few seconds of each other. I took the jpegs straight from the camera and loaded them into Photoshop. I cropped (not resized) the DSLR picture to match the size of the P&S picture. Then I copied each into a new image to eliminate the EXIF data. Finally, I saved each as a jpeg at the lowest compression available. -- Doug |

A is the DSLR, in my opinion, because of the dust spots that are visible on
the image. SS. "Douglas Johnson" wrote in message ... This might be fun. Yesterday, I took two pictures. One with a Canon SD890IS and a second with a Nikon D300 with the Nikon 18-200 mm zoom.

I'll go with A as the DSLR. It seems to show a little less DOF in the foreground leaves and B is more heavily sharpened with more blown highlights, a lot of noise in the blown aqua sky and a bunch more chromatic aberration. I sharpened both in irfanview to emphasize differences, then raise the gamma & contrast to 2 and the differences are real obvious. Caveats: B is exposed a little brighter which could explain the blowouts (but ought to reduce noise) and sharpened more which could explain the leaves looking a tad sharper. The 18-200 is not the best lens so could conceivably be B with the chromatic aberration problems. Depending on the settings the DSLR jpeg might be over-sharpened or too contrasty.

I could easily be wrong though, as user settings can swing it either way. |

However, that COULD be due to more native sharpening typical in P&S cameras. I think the important point here is that experienced observers find it VERY difficult to see significant differences in images from a $325 P&S and a top notch DSLR selling for 5X as much.

At that tiny size, yes. I'd guess A, fwiw, not much! == -- john mcwilliams |

I figured A was the P&S, without looking at the B moderate-size
version. I reckoned it was easier to zero-out the dSLR's in-camera processing (or it was less likely to be overboard initially), and the P&S was extensively processed before Mr Johnson got to it. -- Frank ess Douglas Johnson wrote: This might be fun.

Is there any avid photographer who has a high end P&S and a dSLR who has not
compared essentially identical images from the two cameras? I began doing this with my late lamented Sony 828 and my still used Nikon D70 and later D80. The dSLRs were not always obviously better. Currently I pit a Panasonic FZ18 against the dSLRs. Alas, the Panasonic is such a noisy beast, even raw at ISO 100, that it is usually not difficult to tell which camera made which image. However on a hot day lugging the FZ18 around sure beats hauling around an SUV sized dSLR and 18-200VR Nikon zoom. |
