-Cameras use different levels of in-camera image editing. Compact cameras will apply more sharpening to make the image look snappy. Advance compacts are more neutral and SLR cameras tend to have minimum editing or sharpening done in the camera. Keep in mind that the camera has only limited processing power, it was not really designed to perform unnecessary editing steps. Depending at what stage the user adjustments are made in the camera will determine if the changes are degrading the image file quality or not. When using PC image editing software one can take better care not to negatively impact file quality. How does it happen that the image file are damaged? When working with JPEG files one should always work on a copy and not the original. The JPEG format further compress the file every time it is saved therefore degrading the file.I also made a video for a preview of  <a href="​http://​www.youtube.com/​watch?​v=Q24y1xL2_bY">​Canon powershot camera</​a>,​ please take a look and let me know what you think.+====== Quantitative Archaeology Wiki ======
  
-Because light and shadow come to the fore in black and white photography,​ play with the framing in your pictures. Taking black and white photos framed by, say, the branches ​of a tree or an architectural arch can produce beautiful effects. Black and white photos can add an air of romance, class, timelessness and mystery to otherwise ordinary photographs. A run-of-the-mill color photo may look entirely different when seen in black and white. For this reasonboth wedding and gothic photography have embraced the timeless quality of black and white photos.+This wiki is dedicated ​to the development ​of free documentation about quantitative methods ​in archaeologyusing free/open source software.
  
-After you?ve been processing your photos ​for a little while, some lessons ​about how digital photography works ? and the limitations and strengths ​it has ? will become ​more apparent to you. You can then keep these in mind when shooting ​and change your settings or shooting technique ​to avoid running into any problems ​and make the most of the format.+===== Contents ===== 
 + 
 + 
 +==== Digging Numbers ==== 
 + 
 + 
 +Our first attempt is to rewrite the exercises ​for the textbook "​Digging Numbers"​ by Fletcher and Lock using the **''​R''​** statistical software. This part is still in development,​ so if you can help, please do it. ☛ [[diggingnumbers:​start|Go to the Digging Numbers exercises]]. 
 + 
 + 
 +==== Sum of individual weighted means ==== 
 + 
 +This is method to calculate with enhanced precision the chronological distribution of archaeological artefacts that have long time spans. ☛ [[sum of individual weighted means|Go to the weighted means page]] 
 + 
 +==== Contingency Tables ==== 
 + 
 +This is a basic introduction to frequency and contingency tables using **''​R''​**. A function for plotting Ford “battleship” diagrams is presented. ☛ [[contingency tables|Go to the contingency tables page]] 
 + 
 +==== Spatial Analysis ==== 
 + 
 +Tutorials about spatial analysis techniques using free geospatial software like GRASSR and others. ☛ [[spatial_analysis:​start|Go to the spatial analysis introduction page]] 
 + 
 +==== Plotting quantitative pottery data ==== 
 + 
 +☛ [[pottery:​start|Go to the quantitative pottery data page]] 
 + 
 +==== Archaeometry ==== 
 + 
 +Statistical analysis is very often already included in the archaeometric study of materials. Here we try to perform ​some common analysis with the R programming language. ☛ [[archaeometry:​start|Go to the archaeometry page]] 
 + 
 +==== Monte Carlo simulation ==== 
 + 
 +Enrico R. Crema has some interesting R scripts for Monte Carlo simulation on his website: http://​www.homepages.ucl.ac.uk/​~tcrnerc/​Downloads.html 
 + 
 +==== Quantitative Archaeology summer school ==== 
 + 
 +Some brief notes taken at the [[qmdaa:​start|I-QMDAA Summer School]] in 2006. 
 + 
 + 
 +===== Bibliography ===== 
 + 
 +We are collecting references to published manuals and journals ​about Quantitative Archaeology [[bibliography:​start|in this section]]. 
 + 
 + 
 +===== Mailing List ===== 
 + 
 + 
 +There'​s an [[http://​list.iosa.it|international mailing list]] to discuss about quantitative methods, free software in archaeology,​ open formats ​and more. The list is kindly hosted by the [[http://​www.linux.it|Italian Linux Society]]. 
 + 
 +However, the [[https://​groups.google.com/​forum/#​!forum/​antiquist|Antiquist]] Google Group is more active than “our” mailing list and you may get better answers there. 
 + 
 +===== About Quantitative Archaeology Wiki ===== 
 + 
 +This website is a wiki. This means that:  
 +  - **you can contribute** ​and improve the existing documentation,​ even with small edits 
 +  - anyone will be able to read, edit and possibly improve your contributions  
 + 
 +You should contribute documentation about free and open source software, but general documentation about algorithms and statistical methods is also good. 
 + 
 +The documentation is released under the [[http://​creativecommons.org/​licenses/​by-sa/​3.0/​|Creative Commons Attribution-Share Alike 3.0 Unported License]] (CC-BY-SA 3.0).

Follow the link to the license page to learn more about your rights. 
 + 
 +A brief **[[todo|TODO list]]** will be helpful to coordinate our work towards building a comprehensive guide to quantitative methods in archaeology. 
 + 
 +This wiki uses [[wiki:​dokuwiki|DokuWiki]] as backend. Documentation for editors is available on the Dokuwiki website. A brief [[wiki:​syntax|syntax reference]] can be accessed from each page while editing. 
 + 
 +The **Quantitative Archaeology Wiki** is hosted by the IOSA Project.
