JPEG 2000 Part 1 (Core) jp2 File Format There is increasing implementation of JPEG 2000 in archive and library digitization of books, pictorial collections, maps, and other materials that can be reproduced as still images. A good overview was provided at the JPEG 2000 Summit held at the Library of Congress in 2011. Meanwhile, the Wellcome Library in the UK has evangelized for greater use of the format in digitization projects. Many image manipulation programs and software libraries can now read and write JP2 files. Examples of significant adoption of JPEG2000 include the Digital Cinema Initiative (see Digital Cinema Initiative Package (DCP), Version 1.0) and use by the High Resolution Imaging Science Experiment (HiRISE) flying on board NASA's MARS Reconnaissance Orbiter mission. At the same time, JPEG 2000 encoding is not generally built into still-photography camera chips nor is JPEG 2000 decoding native to Web browsers, and this has led some commentators to compare JPEG 2000 unfavorably to JPEG_DCT in terms of adoption.
Online Photography Courses, Photo Software Reviews, Camera Reviews and more Learn Photography A whole new way to learn photography I’ve spoken with thousands of people who – despite the beginner or even intermediate courses they’ve taken – are still confused about the basic elements of photography. It’s obvious that many traditional methods of teaching photography just don’t work! I’ve developed my own style of teaching.

Priced at about $499, this Sony mirrorless camera is highly recommended if your budget is keeping you at around the $500 level. If budget is not a concern, I suggest you jump down to the “Better” or “Best” recommendations. Better Camera: Sony NEX-6 Starting at around $750 which includes an 16-50mm lens. Best Camera: Sony a7R
Comparison between JPEG and JPEG 2000 JPEG 2000 offers numerous advantages over the old JPEG standard, and several of these advantages will be discussed. One main advantage is that JPEG 2000 offers both lossy and lossless compression in the same file stream, while JPEG usually only utilizes lossy compression4. JPEG does have a lossless compression engine, but it is separate from the lossy engine, and is not used very often. Thus, when high quality is a concern, JPEG 2000 proves to be a much better compression tool. Because of the way the compression engine works, JPEG 2000 promises a higher quality final image, even when using lossy compression. Figure 1 Comparison of two images compressed using JPEG and JPEG 2000 A second advantage of JPEG 2000 over JPEG is that JPEG 2000 is able to offer higher compression ratios for lossy compression. An example of some PSNR efficiencies for JPEG 2000 and JPEG is shown in Table 1. Table 1 Comparison of PSNR compression efficiencies(in dB) for two images at various bit rates Half size
Photography Tutorial: A Quick Guide to Understanding Your DSLR Camera Hi guys! With Labor Day weekend coming up, I know a lot of us are going to be out there taking pictures! :) Since we have a long weekend to practice, I wanted to share with you this basic intro to SLR photography. If you have an SLR camera and are nervous to take it out of auto mode, this is the tutorial for you. You may have heard words like aperture, exposure, and shutter speed and wondered just how on earth they come together to give you a better photo. Left: Canon T2i. To start, let’s put your camera in Aperture Priority mode or Shutter Priority mode. 1. Let’s talk a little bit about Aperture. Photos taken with a low aperture let in more light, allowing you to take pictures in situations where there is not much light (like indoors and at night). A low aperture will also give you a shallow depth of field. Canon 50mm f/1.8 f/1.8 1/200 sec ISO 800 In the photo above, the aperture was set to 1.8, a low aperture. Canon 24-70mm f/2.8 f/16 1/60 sec ISO 100 Now you try! Set your aperture. 2.
JPEG2000 vs JPEG (vs TIFF) Introduction JPEG2000 is a fairly new standard which was meant as an update of the wide-spread JPEG (Joint Photographic Expert Group) image standard. JPEG2000 may share its name with the older standard but under the skins the relationship between the two is next to nil. Now where's the beef ... ? Better efficiency in compression (incl. 48 bit color depth support) Possibility of lossless compression> Decoding with different output resolutions> A process to calculate the integrated bit rate (possibility of reaching an aimed bit rate) Dividing the image into smaller parts to be coded independently from the others Improvement in noise resilience Access to the compressed bit rate at any point in order to access the image directly Better performances in coding/decoding through many different cycles More flexible file format The current reality The Tool The JPEG2000 dialog box is pretty simple. Let's have a look at it ... JPEG2000 vs TIFF References:
Beyond Instagram: Should photographers accept the risks inherent in social networks? In the early days, Instagram was liberating for journalists and photographers, saysKarim Ben Khelifa. “In most cases, we never really meet our audiences, and with Instagram you can interact directly with your followers. When you think about it, Instagram, more than Facebook, is the perfect tool for photojournalists. For Tomas Van Houtryve, a VII photographer, Instagram has allowed him to take pictures he’d stop taking altogether. But with the fear of Facebook using Instagram’s data and content to generate revenues, photographers have been rethinking their approach to the platform. “We’ve become complacent with the only commodity we have as photographers – our copyright – in our near unfettered embrace of sharing our content with for-profit companies such as Instagram,” says John Stanmeyer, one of the original founders of the VII Photo agency. And that’s precisely what Instagram is good for, argues Ben Khelifa. For Ben Khelifa, of course, that platform could be Emphas.is.
Tutorial: Shooting Double Exposures with a Canon 5D Mark III Cameras today have many extra functions that are often buried in menus and forgotten. Last year, I bought the Canon 5D Mark III and, after a few months, realized that there were some interesting features I had never played with. After figuring out that there was a way to do in-camera double exposures, I immediately started experimenting. At first it was very hit and miss. (I still hadn’t read the manual.) Ever since I posted this image, I’ve been getting messages asking: “How do you do this!?” Multiple Exposures: What Are They? Double exposure is a technique that originated with film photography where you would expose the same frame of film twice (or more). There are a number of digital cameras that can do this: Canon 5D Mark III, Canon 1D X, Canon 6D, most Nikon DSLRs, Fujifilm X Pro1, Fujifilm X100S, Olympus OM-D E-M5, and more! Some Tips for the Canon 5D Mark III Live View. Pick Your Base Image. The Images Sometimes I want to have more context and facial texture in the subject.
Learn Composition from the Photography of Henri Cartier-Bresson “Do you see it?” This question is a photographic mantra. Myron Barnstone, my mentor, repeats this question every day with the hopes that we do “see it.” This obvious question reminds me that even though I have seen Cartier-Bresson’s prints and read his books, there are major parts of his work which remain hidden from public view. Beneath the surface of perfectly timed snap shots is a design sensibility that is rarely challenged by contemporary photographers. Henri Cartier-Bresson. © Martine Franck Words To Know 1:1.5 Ratio: The 35mm negative measures 36mm x 24mm. Keep these terms somewhere you can easily refer to, since without them it is difficult to navigate a composition. Photography is a Verb Why is Henri Cartier-Bresson such a good photographer? JAPAN.

Blog Every retoucher knows that just the right touch of Noise can help hide various issues when working on an image. There's something about the random texture Noise adds that helps hide areas where there might be some artifacts left after working on extensive spotting or reconstruction of an image. The most common way to add Noise is to create a new layer, set the Blending Mode to "Overlay", fill it with 50% gray then use the "Add Noise" filter. Several years ago a retoucher friend tipped me on to the idea of using a Pattern Fill layer to add Noise. Since this method is based on a Pattern and a formula it not only adds fewer Megabytes to your file size, but you can easily change the Pattern by simply clicking on it in the appropriate window and choosing a new Pattern. This method works great and it's been my favorite way of adding Noise for several years. But what if you're working on a file that has several layers and you just need to add Noise to 1 or 2 of these layers? Cool, eh?
Metabones® - Home The Numbering Affair by Alain Briot My ideal is to achieve the ability to produce numberless prints from each negative, prints all significantly alive, yet indistinguishably alike,and to be able to circulate them at a price not higher than that of a popular magazine, or even a daily paper.To gain that ability there has been no choice but to follow the road I have chosen. Alfred Stieglitz 1 - Introduction This essay stems from my ongoing reflection on the subject of limited edition prints. The essay also comes out of what I see as the increasing importance of the "limited edition debate", for lack of a better term (there's really no specific name for this debate which is mostly informal, though important, at this time). The "clincher'", for me was the realization that at a time of constant technical improvements, limiting and consequently discontinuing new printings of an image (and by implication discontinuing landmark images eventually) was preventing the creation of better and better prints of this image.
