Denali's Cassin Ridge in very high resolution

Mon, 25 Aug 2008 02:25:39 +0000

For anybody with an interest in attempting to climb Denali's Cassin Ridge, here's a very high resolution image I created by combining several single frames of sections of the route. Apologies for the portions that are not quite sharp. With a 400mm lens sticking out of a plane window going nearly 100mph with temps well below 0 F, I was happy to just get the frames I needed to make this image. 1/1200 of a second may not have been fast enough with that focal length, or perhaps the autofocus was fighting the fierce wind..... Enjoy!

Innovations in Journalism

Sat, 14 Jun 2008 00:30:00 +0000

Fotovision was a sponsor for the May 3rd “Innovations in Journalism Expo”. The day long event, organized by the Society of Professional Journalists and Independent Arts and Media, promised to “showcase cutting-edge work that combines journalism, technology new business models and philanthropy” and to “push the envelope with fresh ideas in a time of crisis for the news industry.” Fotovision's Program Coordinator, Adrianne Koteen, Executive Director Melanie Light, and I enthusiastically carpooled to Palo Alto to glean what we could from the event. The day proved to be not only engaging, but a bit overwhelming, and certainly inspiring. The one day Innovations in Journalism Expo that we attended was simultaneously its own event, and also the final day of a 3 day symposium called “NewsTools2008/Journalism That Matters.” The Journalism That Matters events are facilitated meetings held around the country that bring journalists together in large “open space” conversations aimed at addressing the challenges and opportunities in journalism today. Journalism That Matters co-founders Peggy Holman and Stephen Silha were there to “host the conversation”. This particular Journalism That Matters meeting was in Palo Alto; the conversations were particularly infused with lofty ideas of creative ways to use the Internet to assist the dissemination and creation of quality journalism. We had arrived in the afterglow of 2 days of brainstorming and excited information sharing. Butcher paper hung from the walls with intricate “Value Network Maps” drawn expertly by Sherrin Bennett. One map graphically displayed the interrelationships people in what they termed the “Old News Story” - how people worked together in the past to produce news. This map was contrasted by another of the “Emerging News Ecology” of today where the audience is actually engaged in the creation of news, and the bloggers and “Community Weavers” arise as a necessary role from the importance of community driven websites in journalism. Some attendees expressed some boredom with the standard panel discussion format of the Innovations in Journalism Expo. One attendee of the three day conference, Hemant Bhanoo, is co-founder of the Berkeley based company Reporterist. Reporterist is creating an online marketplace for freelancing journalists. Hemant told me that he was having difficulty with the rigid format of the standard panel discussions in the Innovations in Journalism Expo after so many days of intense conversation and idea generation. But for me, having not been to the previous two days, I found the panel discussions quite engaging. One panel on “Funding and Journalism” featured David Cohn. David is working on a model he calls “Spot Reporting”. “Spot Reporting” is an online mechanism that journalists can use to get donations for their projects. Collectively, the micro-funding from small online donations becomes enough to fund the project. We have seen countless examples of independent journalists funding their projects through tip jars on blogs. David Cohen's project is working to put people that want to micro-fund journalism projects and journalist together in one online application. Like any new idea, David Cohen's idea is by no means isolated. Another attendee, Leonard Witt, has been talking quite a bit about his concept of “Representative Jounrnalism”. Leonard Witt suggests that if news organizations are to survive, they will have to begin to cater to the niche. Rather than think of circulations of hundreds of thousands, news organizations will have to begin to think of hundreds of circulations of one thousand, with the niches themselves providing the funding and demand to the news organization for the coverage. Like David Cohen's project, Leonard Witt's idea integrates the audience itself in the creation of the news. But these were just a few of the people we met at the conference. And just a couple of the compelling ideas. With sessions organized on “New Money, New Media, New Hope”, “Journalism Before Profits: The Future of Public Media”, and a career counseling session set-up like “speed-dating”, there was an abundance of exciting ideas and people. By the day's end, I felt inspired by all the work being done at the bleeding edge of innovation to help shape the direction of journalism in the US, and excited by the possibilities in photojournalism.

Digital Railroad Feed Read

Tue, 22 Apr 2008 21:36:29 +0000

I enjoy working in the space where the web and photography intersect. Digital Railroad, an online asset management tool, and sales platform, helped to sponsor Mikkel Aaland's Tasmania Lightroom Adventure project that I was fortunate to be a part of.

Between the shooting I'd be doing and the eating and sleeping in Tasmania, I was there to help in getting the team's images out to the web. It proved to be an interesting task!

In the end, photographers were able to create nice web galleries in Lightroom pretty efficiently, and I made a page that simply linked to them all. But some of us who were familiar with Digital Railroad were using it to publish images to a different platform.

I wanted our collective work on Digital Railroad to be displayed on the various websites that were interested displaying the team's work in the field in various formats. So I wrote a script to read Digital Railroad's XML feeds so that I could present the new images in various ways. You can read more about the DRR Feed Read here

Copyright 2.0: Copyright in a Hyper Digital age

Fri, 18 Apr 2008 23:34:40 +0000

Photographer Gerald Bybee and I pulled off organizing a very informative session last night in San Francisco. I work on the board with the local chapter of the American Society of Media Photographers. The ASMP seems a bit behind the times when it comes to the massive changes that are dramatically altering the photo industry and indeed the very fabric of our culture! So it was exciting to get the general counsel of ASMP and the VP of Creative Commons, along with some other well known lawyers to discuss the new world of Copyright 2.0 in a Hyper Digital Age.

Lightroom Flash Galleries Security Issue

Fri, 30 Nov 2007 23:35:08 +0000

I've been using Lightroom's Flash Galleries lately as a mechanism to get images efficiently and beautifully published on the web, and I was uncomfortable that the image files are output by Lightroom to the web as publicly downloadable jpgs in high resolution! One of the reasons photographers like to publish things on the web in flash is because the images are a little more difficult to steal. An image thief would have to do a screen shot in order to obtain the image presented in flash. Unfortunately, the Lightroom flash galleries have all the images as jpgs in directories that are easy for people to browse and steal. So the fix I implemented involves not allowing apache to give people access to those files. The flash gallery doesn't get the images through apache, so it doesn't matter. Adobe could fix this problem with an .htaccess file automatically generated for each directory. But until then, to make the jpgs in a Lightroom Flash Gallery secure, here are two approaches: 1) Do this to httpd.conf: # this is to secure the image files in the lightroom exports from lightroom Options -Indexes Deny from all Allow from all this makes it so that all the Lightroom galleries that I upload into portfolios can be viewed, but that nobody has access to any other file in there via Apache. It also makes it so that Apache doesn't show the contents of each directory. Flash doesn't have a problem reading the images, because it isn't doing it through Apache, so the flash galleries continue to work fine. 2) Another approach, though less secure, would be to disable the default Apache habit of creating an index of all the files in a particular directory for people on the web when it can't find an explicit index file. So if somebody browses to /portfolios/Nice_Pictures/bin/image/large they Apache will tell them exactly what is in that directory: Your hires image! To fix this, put Options -Indexes Unlike option 1 above, the files are still accessible to people via apache, but people will have to guess at the names of the files. Not impossible to guess the names, but it is a little more secure than having Apache just let everyone know what the names are!

A quick tutorial on color management: Getting colors right on the web

Mon, 05 Nov 2007 23:11:19 +0000

Browsers don't color manage! Convert images to sRGB to display them correctly! Digital photography is about digits. Numbers. That's why it is called digital. When you take a picture, your digital camera takes all of the colors that you have presented to it in that brief flutter of the shutter, turns them into numbers and stores them somewhere. When you get home and look at the image that your camera has made, your computer then takes all of those those numbers and turns them back into colors for you to see. Then you tweak this or that, adjusting the contrast, color correcting and adjusting the white balance. When you are happy with what you've produced, you might transmit it out across the internet to your favorite printing service to be made into a digital print. Like your monitor, the printer that you've sent the image to is now tasked with turning those numbers into colors with their device. Through this whole process, wouldn't it be convenient if each number represented exactly one color, always, without exception, to every device on Earth? Unfortunately, this is an impossible dream. We do have absolute references like the Pantone colors where one number is exactly one color, universally. And that is very helpful for many applications, but there is no practical way that every camera, monitor, printer and scanner could ever call the exact same color the same number. Even if every device across the planet were in perfect agreement with each number being exactly one color, one device might have a greater ability to reproduce a wider range of certain types of colors than another device, and we'd have to take that into account somehow. So digital photographers have to know how their devices turn color into numbers or vice-versa. I know how my monitor will turn numbers into colors. I know how my printer will turn numbers into colors. And I know the opposite - how my scanner will turn the colors into numbers. When I say "know" it isn't like, "my monitor displays things a bit warm, and the printer that makes my big prints for me tends to be cooler" That is an impossible way with dealing with color. One could never get the colors of what one sees on a monitor to match a print this way. Instead, I rely on color profiles. A color profile is a set of instructions stored in a file about how a device (a monitor, a printer, a scanner, a camera) turns a number into a color or vice-versa. A color space is similar to a color profile. A color space, however, doesn't necessarily correspond to a particular device like a profile does. A color space serves as a convenient container to put all those colors in while working on the image in image editing software. You can think of a color profile and a color space as a big sack that we fill with tennis balls each of a different color. The bigger the sack, the more colors we can fit in! I have software and a device that builds a color profile of how my monitor displays colors. It works like this: The software says here's this number: 220000 and tells the monitor to show a big square of the color that the monitor recognizes that 220000 to be. Then, I stick a device not too different from a digital camera right to the monitor and it records how the monitor displays the color and says back to the software, "the monitor displayed 220000 like 221010". And the software says, "that's great information, now how does the monitor display this color?" And so on. With enough cycles of this with different colors, the software builds a profile of how the monitor turns numbers into colors. I can go through the same process for discovering how my printer turns numbers into colors. And then, once I have all these profiles, and know how each device interprets or outputs color, I can be sure that what I see on the screen will be what I see on a print. But, what if now I want to put an image on the web? I haven't a clue about how the thousands of monitors that will view my image will turn those numbers into colors. We can never hope to profile all those monitors, but we can take a good guess. sRGB is a color profile proposed by Microsoft and HP as an approximation of the color profiles of the most common computer displays. sRGB, like most monitors, is described as having a very "narrow color gamut". Returning to the sack of tennis balls analogy, sRGB is a tiny sack. There is a lot of color information that the monitors and sRGB simply can't display. We run into problems when we work on images in image editing software in a huge "wide gamut" color space like ProPhoto RGB, and then export the images as JPEGs to show on monitors with a tiny color gamut that cannot possibly display all the colors in the color space we were working with. When we make this mistake, the images look perfect in our image editing software, but when we export them as jpgs and view them through a web browser, the colors are very desaturated and look strikingly different. Here's why: Browsers do not color manage the way image editing software does. Even though our jpg explicitly states in its metadata that its color information only make sense in the ProPhoto RGB color space, the developers of browsers are concerned with developing pop-up blockers and security features, not figuring out ways to extract color space information from images and converting them to look perfect on everyone's monitor. The developers of browsers have ignored color management. Image editing software, in contrast, is good with color management. It knows that I am viewing my images through a monitor, and it knows the profile of the monitor, so even though I am working in the ProPhoto RGB color space, my image editing software picks and chooses what colors to take out of the enormous sack of my ProPhoto RGB color space and pack it into the tiny sack of my monitor profile so that the image looks like it should. So the browsers, not color managing, just assumes that every image is made custom for display on the tiny color space of the monitor. If you give a browser an image with a wide range of color information from an enormous color space like ProPhoto RGB, the color information will be essentially clipped - thrown out. What you end up seeing is a strikingly desaturated image. To solve the problem, we need to do the color management for the browsers by converting the image to sRGB, our best guess at how monitors are going to reproduce colors. In Photoshop there is a "Covert to Profile" feature. In Lightroom, we can choose the destination profile when we export. Only by converting the profile can we can export as a jpg and expect to display our photos on the web the way that they look to us in our image editing software. This is a ProPhoto RGB colorspace image. If the image looks desaturated compared to the image below, it is because your browser doesn't color manage to convert this image to your monitor's profile. When viewed in image editing software, the software is "color managing" - taking into account the profile of my monitor, and it converts the ProPhoto RGB color space into a profile appropriate for my monitor. Web browsers, however, do not color manage. So when this ProPhoto RGB colorspace image is presented on a monitor through a web browser, colors are essentially clipped, and we end up with a desaturated image instead. Same photo but now manually converted to sRGB to do the color management for the browsers. To deal with the fact that browsers don't color manage, do the color management for them and convert images to sRGB. Much better! Check this page in a few years. Perhaps by then, web browsers will be color managing, and the two images above will look pretty darned identical.

Occasionally I write about some photography related topics that are interesting and important to me. If below is blank, that's because I haven't written anything on this note pad for the last 30 days - But there are plenty of interesting items in the archive on the right. Cheers, Jeff

Social Change Photography

Thu, 14 Jun 2007 03:23:17 +0000

One of the joys of being on the board of the American Society of Media Photographers NorCal chapter is putting together what I feel are important events for the Northern California community of professional photographers. I organized this event for the ASMP, hoping to put a spotlight on some local heros who support what we should call "social change photography". Read my review of the event.

Lawrence Lessig Speaks in Doha, Qatar

Thu, 10 May 2007 19:47:12 +0000

Lawrence Lessig is a professor at Stanford Law School and the founder of Center for Internet and Society. I was at the Al Jazeera Media Forum in Doha, Qatar and heard his keynote address there in April 2007. Lawrence Lessig's talk is perhaps the most succinct and accurate description that I've heard about the role of the Internet today in democracy, society and journalism. His perspective is an important tool in understanding the enormous transformations that we are seeing and participating in today. MP4 video format Windows Media video format
