We need to back off for a bit because I think Lee's explanationCorrect, except I don't consider Camera Raw a safety net - just a better way to setup the image. To fully take advantage of RAW processing you have to expose even more carefully than you do normally because you are flirting with overexposure – if you go to far there's no coming back – no safety net there! The Jpeg clips values at both ends of the tonal range and I'm "placing" the values at the upper limit of the captured data. In some cases this highlight info would be clipped to white in the jpeg so shooting Jpegs this way would not work! RAW processing is not a way to protect against bad exposure so much as a new way to handle digital capture. If you test for this new setup and save new default renderings you can end up with better images but there's no automatic way to handle every image the same way so you do have to spend some time post capture to setup your processing and many, in a time = money workflow may not find enough value in pursuing RAW. Beginners may find RAW to be a "safety net" to protect against mistakes but Professionals will use RAW to squeeze the best possible quality out of an image by carefully placing scene values into the best range of the captured data and setting the rendering or processing for a more ideal value structure – very much like the old B +W negative strategy of "expose for the highlights and process for the shadows". I have an old ACR tutorial for the calibration procedure and I'm currently working on an updated version to handle Lightroom/ACR 4. regards, Lee Varis President, LADIG Photographer and Digital-Photo-Illustrator Author of Skin : The Complete Guide to Digitally Lighting, Photographing, and Retouching Faces and Bodies Lee Varis ISBN: 0-470-04733-X Paperback 432 pages October 2006 varis@varis.com http://www.varis.com 888-964-0024
