All good stuff Artur! I did not know about the loss of quality when saving numerous times with JPEGS. I suppose I should have - the same principle applies when I record video to my hard drive on my DVD recorder. I use the uncompressed speed so my final edited DVD looks as good as it can. Though I don&acute;t do those as often since I&acute;ve gotten so into photography. <br /> <br />Thanks again.

Yes Fred, quality is degraded every time you open, edit and close a JPEG capture. In your case,- if I may suggest - my basic suggestion would be to capture at your camera highest JPEG quality setting - your Pan only has JPEG capture - ( which is in your case is 2560x1920). After the 1st fase of editing ( for me the first fase is adjust any gamma,white balance,curves or contrast if needed and crop the unnecessary parts - if there is some ) and then save the result as TIFF ( this will be your master edited copy + the original JPEG from the camera which remains the unedited image ). Then,already with the TIFF, make the cropping/resizing, - do not forget to adjust sharpness after resizing if necesssary - and if satisfied with the result, save it now in JPEG highest quaility (100) if you want to share your image. If not, save this final copy again as TIFF ( with a diferent ref ) just in case one day you want to transform it in JPEG without the hassle of doing everything again. :Happy HH

As said, raw file formats are proprietary, and differ greatly from one manufacturer to another, and sometimes between cameras made by one manufacturer. In 2004 Adobe Systems published the Digital Negative Specification (DNG), which is intended to be a unified raw format. In 2006, a few camera manufacturers have started to announce support for DNG in newer camera models, including Leica & Pentax (native camera support) and Hasselblad (export). Other manufacturers, however, appear to have little interest making their raw files easier to read: cameras from Canon, Nikon, Sony and others include elements of encryption designed to make it harder for others to decode the format.What&acute;s the point on this? I do not know, really. The Leica Digital Modul-R (DMR) was the first camera to use DNG as its native format. <br /> |O|

I&acute;ve been using the Adobe Raw plugin to start post processing, then into CS2 to finish, then saving in JPEG for uploading. I&acute;ve notice that the displayed image in my browser never looks like the image in CS2, mostly a loss of color. I downloaded the beta Adobe Lightroom and was very impressed with it and then imported the image into to CS2 in the TIFF format, but again the same results with the JPEG file. After reading - third parties raw converters can not read the exact data as the natives (camera brands) raw converters do- I went back and loaded one of my RAW files with the native converter and then into CS2 in TIFF and saved in JPEG and quess what? The image in the browser looks the same as the image in CS2!!! Although the Adobe plugin and Lightroom support my camera, when I saved in JPEG the resulting image was very disapointing. Now the problem is solved. If I had not read your statement about third parties RAW converters, I&acute;am not sure I would have every figured it out.

I always capture in my max resolution... I have a 2 GB card, plenty of room... I would never have saved in TIFF before reading this stuff. Great educational tools here. <br /> <br /> :congrats :congrats :congrats HH
