    <p>"All Photoshop features are faster on a multiprocessor system, and some features are much faster. Note that there is a law of diminishing returns with multiple processors: the more processors you use, the less you get from each addition processor. Therefore, you may not experience expected speed increases if you use more than four processors."<br>

    Motorcyclist charged with videoing cop

    in Street & Documentary

    Posted

    <p>Video cameras are used in all aspects of law enforcement because they provide an accurate account of the situation in question. This incident should be no different. The helmet cam was recording the interaction and as such provided a record that could be used to protect all involved. The problem arises with the chain of custody of the video. Video can be edited to present an altered viewpoint. <br>

    There should be no expectation of privacy regarding an traffic stop on a public road and the interaction of a police officer and a motorist, as the conversation will ultimately be used in court as evidence. <br>

    If in fact the police officer asked the motorist to turn off the video, he was obligated to follow the officer's direction. </p>

    Canon EOS 7D: the best amateur camera?

    in Canon EOS Mount

    Posted

    <p>Camera selection is a very personal choice and although most won't admit it, the primary factor is financial. You get the best camera that fits your budget and for many that camera is the EOS 7D. <br>

    Seven years ago I was in a better financial situation and purchased the Canon EOS 1Ds which was my first professional digital camera. That camera continues to serve me well but is now technologically outdated. I purchased the EOS 7D in December and although it took a while to get used to the crop frame sensor, I quickly adapted. The exposure system and color rendition is superior to my original 1Ds, but the RAW images appear softer with more visible noise than I was used to. Learning to tweak the images in ACR (especially ACR 6.0 that ships with Photoshop CS5) I can now produce images I an completely satisfied with. The addition of HDR video is moving me (creatively) in a new direction with even greater possibilities.</p>

     

    What is a jpeg on Canon 1Ds

    in Canon EOS Mount

    Posted

    <p>With the 1Ds, the quality button on the back of the camera is pressed while turning the back adjustment dial to scroll through RAW, Large/Fine jpeg, Large/Normal jpeg or Small jpeg. <br>

    To select RAW + jpeg you must enable the function using the menu screen on the back of the camera. When this option is selected in the menu, jpeg icon will not be visible in the viewfinder and the jpeg quality icons will not be visible on the rear LCD panel.</p>

    Photoshop CS5 for a photographer - will it help or kill ?

    <p >Programs evolve to simplify workflow. We find new ways to get to the same conclusion.</p>

    <p >This is the also the case with Photoshop CS5. There are a lot of grumblings about how "new" features such as content aware fill, auto lens correction, HDR or edge refinement are not new at all. They have all been available in previous versions or in some plug in. That may be the case, but now they are available in one program and are refined to make them easier to use.</p>

    <p >Isn't that the real goal, to make the best possible image in the least amount of time?</p>

    CS5 disappointments

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>I was a Photoshop CS5 beta tester and now that the product has been officially announced, I have been given permission to talk about the product. <br /> Bridge CS5 now features Mini Bridge which navigates files from within the application like a tool window that can be resized by the user. It has a navigation bar, file window and preview pane. Bridge now features full frame video and audio previews.<br /> Content aware fill and spot healing brushes are just amazing. The increase in speed on Mac based systems is very good. Finally we can now use all available ram. Automated lens correction is helpful and increased perspective correction can be accomplished using the new puppet warp tool. <br /> In total, the new features increase productivity by accurately reproducing tasks automatically that once took twice as long to accomplish manually.</p>

    Debunking ETTR

    in The Digital Darkroom: Process, Technique & Printing

    <p>The theory explained does not take recent developments into consideration such as Canon 7D iFCL metering system which uses 63 zones, focus linked utilizing both color and luminance information.<br /> http://cpn.canon-europe.com/content/education/infobank/exposure_settings/iFCL_metering.do<br /> Here is Canon's description:<br /> "The EOS 7D features a new, 63 zone dual-layer sensor designed to complement the 19-point AF system. By taking into account the color and luminosity surrounding chosen AF points, this new system delivers an entirely new level of accuracy for better results even in difficult lighting situations. Since the metering sensor has a color measurement function, exposure errors and focus errors caused by different light sources are minimized; the EOS 7D gives stable exposure from shot to shot in situations where light changes, such as in a theater or concert hall. This makes the EOS 7D ideal for scenes with extreme difference in brightness such as brightly lit scenes or backlit scenes; the camera balances exposure of the main subject at the background, and exposures are not overly influenced by bright areas in the shot."</p>

    <p>I bought a 7D in December. It was my first crop frame sensor. My other camera is the original 1Ds. My advice is not to sell the 17-40 f/4 L lens. It produces very nice, sharp images with the 7D. I also use the 24-70 2.8L and 70-200 2.8 IS L with the 7D. The 2.8 lenses activate additional cross hair focus sensors with the 7D. The camera is extremely fast and accurate with a largely increased usable ISO range. Get a fast CF card (UDMA 6) to keep up with the action of the dual processors and frame rate. I bought the Sandisk Extreme Pro 32 gig card. If you plan on shooting video, you will appreciate the increased capacity.</p>

    About to buy HP LP2480zx, should I get the HP LCD Calibration kit?

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>Hi Barbara,<br /> I have been using the LP 2480zx since January of this year and agree that it is the best monitor I have ever used. The HP Advanced Profiling Solution is a critical part of this package as it contains a custom filtered i1 Display 2 colorimeter and related software necessary to calibrate this specific unit and write to the monitor LUT. <br /> The Dreamcolor monitor is the only wide gamut monitor on the market that can accurately calibrate seven distinct color spaces. This information is written to the monitor LUT so that the user can switch to any desired color space with the push of a button. This monitor also offers the widest gamut currently available.</p>

    canon 1Ds Canon 5D how do they compare

    in Mirrorless Digital Cameras

    Posted

    <p>I have the original Canon 1Ds (11.1) megapixel camera that I bought new in 2003. It is a fantastic camera with large pixels (8.8 microns). I still use this camera today and it produces gorgeous images. The camera is full frame (no crop factor) and has the pro body with 45 point autofocus system.<br>

    You can buy a used 1Ds today for a fraction of the original price (which was $8000.).<br>

    LED backlighting versus CCFL (advice pls on monitor purchase)

    <blockquote>

    <p>So unless you like to be on the bleeding edge, or you have very deep pockets like Gerald, you might want to take a breather on this pup until its received thumbs up from those in the industry, working with imagery say so.</p>

    </blockquote>

    <p>Investing in a color accurate monitor is an important choice that should not be compromised. You pay thousands of dollars for your camera, computer and printer and then want to save a few dollars on a monitor? This is the screen that you will be spending most of your time sitting behind and editing those images with. Unlike these self-appointed color geeks who thrive on revenue received from corporations, touting their product at trade shows with a great deal of bias. I would not give advise about a product I did not personally own and use on a daily basis. I am just a photographer and graphic designer trying to make a living in my field. I receive no compensation for product endorsements.</p>

    <p>I have the HP LP2480zx DreamColor display and have to disagree with Mr. Rodney who has no personal experience with this display. It is a wonderful display that is capable of displaying 133% of NTSC color, 100% of both AdobeRGB and sRGB. <br>

    The claim that the monitor is ill suited for photography because it was designed for the film industry is ludicrous. We are all looking for color accuracy and a monitor that can switch from Adobe RGB to sRGB with the push of a button certainly helps my workflow.<br>

    There is no other monitor on the market that can reach the color gamut of this monitor. The 1000:1 contrast ratio is not a minimum but a maximum. Black level can be adjusted in the OSD. <br>

    We do have video cards on the market that can output 10 bits per color via DVI. The ATIX1900XT installed in my Mac Pro is one.<br>

    In addition to DVI, the monitor also has inputs for HDMI and display port as well as component and sVGA. This is a well rounded monitor with outstanding color accuracy. I do recommend purchasing the HP Advanced Profiling solution which comes with a specially filtered i1 Display2 and software that enables the calibration to write to the monitor's two stage 12 bit LUT. <br>

    The price reduction from $3499. to $1999. until January 31, 2009 makes this monitor a solid choice.<br>

    Best monitor

    <p>The best monitor is the HP Dreamcolor (LP2408zx) 24" RGD led backlit monitor that can display 133% of NTSC color, 100% of both Adobe RGB and sRGB. You can switch to any of seven colorspaces with the push of a buttton. It has a 12 bit LUT built in and a 30 bit IPS panel. I have had mine for about 5 days now and it is truely amazing.<br>

    Hp is sponsoring a promotional sale until January 31st, 2009. The monitor which normally sells for $3499. is selling for $1999.<br>

    HP Dreamcolor LP2480zx

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>The HP LP2480zx 24" DreamColor monitor arrived today along with the monitor hood and custom filtered colorimeter manufactured by Xrite as part of the HP Advanced Profiling Solution. <br /><br />The colors appear to be very saturated and did benefit from calibration. The calibration software (which does run on both Mac and PC) allows you to calibrate each built in color space or create your own. Gamma, luminance, white point and RGB primaries can all be set prior to calibration. Black level can be adjusted manually in the OSD. The calibration procedure is very fast and information is saved in the monitor LUT and not the video card.<br /><br />This monitor displays 100% of Adobe RGB and sRGB.<br />The default setting (Full) is the widest possible color gamut which make colors very saturated in non color managed applications. The beauty of this monitor is that you can instantly change to one of seven preset color spaces including Adobe RGB and sRGB with just the push of a button.<br /><br />There are inputs for DVI, HDMI, Display Port, sVGA, component and composite. It also has a USB hub with 4 ports. The monitor can be swiveled, tilted and rotated 90 degrees for portrait mode.</p><div>00S2YW-104225584.jpg.ce4886970578e45b7e615f4b9d7f9065.jpg</div>

    Would you recommend a Wacom Cintiq?

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>I have been using the Cintiq 20WSX for about a year now as a second monitor to my 20" Apple Cinema Display. As the other poster mentioned, it is great for graphic work. I work with Photoshop, Illustrator, InDesign and Corel Painter X.<br>

    I just ordered the HP DreamColor LP2480zx RGB LED display to replace my Cinema Display as a color accurate monitor. They are on sale now direct from HP for $1999.</p>
