P&S versus DSLR -- actual photos for comparison
It is said that a picture is worth 1,000 words. Accordingly, I set up a
tripod and took a bunch of pictures of the same subject with a P+S camera and a DSLR. The cameras I used were the ones I happened to have handy: A Canon SD800 (7.1 megapixels) and a Nikon D700 (12.1 megapixels). In all cases, I set the camera to delay for a few seconds before taking the picture, to allow any vibration from my hands to settle down. I used a 50mm f/1.4 lens with the Nikon; I set the lens to f/11 for all pictures because I think that is close to the optimum image quality. This particular P&S does not allow manual aperture adjustments, so I had no choice but to let the camera pick the aperture. The DSLR offers an ISO range from 200 through 6400, so I took pictures at 200, 400, 800, 1600, 3200, and 6400. The P&S offers an ISO range from 80 through 1600, so I took pictures at 80, 100, 200, 400, 800, and 1600. For each picture, I have posted a scaled-down version of the picture and a full-size crop from the center portion of it. Aside from scaling and cropping, the pictures are exactly as they came from the cameras; I have not applied sharpening, additional noise reduction, or any other image-processing algorithms. I invite you to look at the pictures and draw your own conclusions. You can find them he http://www.pbase.com/ark/ps_versus_dslr |

LOL, you think you are telling anyone something new? :-) We know you have got the labels back to front anyway.... ;-) I invite you to look at the pictures and draw your own conclusions. You can find them he http://www.pbase.com/ark/ps_versus_dslr |

Doncha just love someone making a suggestion for you to do more work when you've already done something for them? -- Tony Cooper - Orlando, Florida |

... So what SW and specific steps did you use to do this? There are many scaling methods. And since these are jpgs with no exif it appears these may possibly have been resaved. I used a program called "JPEG Wizard" to do the cropping. After that, I uploaded the original JPEG files and the cropped output files from JPEG Wizard onto Pbase. Any further transformations were done by Pbase as part of putting the images into their galleries. I see no obvious visual difference between the cropped images on Pbase and corresponding sections of the original JPEG images on my machine. |

In order to get a 28mm equivalent at the wide end, the quality of this zoom lens is compromised. Why not compare with a P & S with a better lens? Morton |

It seems particularly noticeable in the Civilization & Capitalism series. My guess is that it wouldn't be a problem in a 4x6 print if the image was captured at ISO200. Larger prints and higher ISOs might be disappointing. As usual, the selection of the tool depends on what you want for an end result. Thanks for doing the test and reporting the results. BTW, very nice library. |

Why not compare with a P & S with a better lens? Because it's the one I had available. You're welcome to take similar pictures with whatever camera you like and post them. If you want to try for a similar scale, the bookshelf in the photo is 40 inches wide. |

A few points are worth noting: The P&S at 80 ISO and DSLR at 3200 ISO, give roughly equivalent noise levels. The p&s also has at least one hot pixel.. The low P&S lens quality is evident in the corners of the image, even at those highly reduced sizes, and there's a lot of barreling. The P&S seems to be suffering from a lot of flare/discoloration at left - was there a lighting issue? |
