Click the dollar sign though and this graph now shows the lower axis as price, or similarly megapixel count.

To the right of the scrolling list is a graph showing the camera’s scores on the vertical axis and the camera’s date of release on the lower axis. Both current as well as older discontinued models are shown.

Only the top 4 cameras are shown, but by scrolling down the list more than 45 other cameras are displayed in descending order. Immediately above is an example of the current (November, 2008) Sensor Ranking scores. Test results are provided in both numeric and graphical formats, and cover metrics associated with Low-Light ISO, Dynamic Range, Color Depth, and DxOMark – which is an aggregate of the other measurements.

These test results are taken from the raw images produced by cameras, and are directly comparable between cameras. Now, in a move that will be hailed by photographers around the world, DxO Labs has released DxOMark, a free web site offering the ability to compare test results from more than 45 current amd past camera models. What people may not have realized is that in order to be able to produce analysis of camera / sensor / lens combinations for Optics Pro, DxO Labs has needed to have a rigorous and comprehensive analysis system – one based on their original DxO Analyzer. This has proven to be very popular and many photographers find it to have become an indispensable tool in their raw workflow, particular with regard to lens correction. After a time though I stopped, because of time constraints as well as the feeling that my efforts in camera reviewing would be best applied to subjective evaluations.ĭxO then brought out their DxO Optics Pro image correction and raw processing system. I was involved with them in their early days as an alpha tester of the DxO Analyzer system, and published quite a few camera and lens reviews using it. The technology is so fast-moving, and also complicated to understand, that even for experience photographers choosing the most appropriate tool for one’s needs can be a daunting process.ĭxOhas been in the business of making digital camera testing systems for a number of years. This is very much the case when it comes to digital SLRs. In our highly completive consumer society sometimes we are presented with so much choice as to make purchasing decisions difficult.
