These unseen photos of Ground Zero following the 9/11 attacks were salvaged from rotting CDs

25 Jun

Archivists Dr. Johnathan Burgess and Jason Scott have published 2,400 previously unseen images of Ground Zero in the days following the 9/11 attacks. The images were found on old CDs purchased from a house clearance sale in New York and shared by a ‘partner’ of Dr. Burgess because it’s ‘about doing what’s right for humanity,’ according to a statement he made to the BBC.

Dr. Burgess said the CDs were in poor condition after so many years in storage, and that a recovery service was used to retrieve some of the photos. At this time, the duo hasn’t been able to locate the photographer or any family members who may know them. Scott says the images were captured with the 3MP Canon PowerShot G1.

The full archive of images has been made available to the public via Flickr. The photos appear to have been taken by a construction worker in the aftermath of the attacks. Emergency and construction workers are featured prominently in the images, as well as debris from the fallen buildings, machinery, dust and the surrounding New York City skyline, including multiple aerial shots.

Dr. Burgess suggests that ‘people who are moved by [the images] should consider donating to a worthy cause of their choice,’ according to the BBC report.

Proposed UK bill will let police officers ground and seize drones

28 Nov

The UK has unveiled another drone bill proposal, one that will grant officers the power to seize drone parts when they are necessary for proving that the drone was used to commit an offense. Under the bill, officers will also have the authority to order a drone operator to ground their drone when needed.

This marks the latest bill out of the UK that focuses on tightening drone security and safety. Back in July, the UK government revealed that it would soon require drone operators in the nation to register their UAVs and to complete a safety test before operating the device.

The new proposed legislation, simply called the Drone Bill, snowballs into the previous announcement, with UK officials saying in a statement that mandates will require operators to register their drone and also to use apps for planning a safe flight. The upcoming law may also include a ban on operating drones near airports or above 400ft.

The Drone Bill is scheduled to be published next spring.

Broken Ground: Poignant Earthquake Memorial at Epicenter in China

03 Aug

[ By WebUrbanist in Architecture & Public & Institutional. ]

disaster landscape

A visceral memorial to the nearly 100,000 victims of China’s 2008 earthquake, this weathered-steal monument and museum conjures images of cracked Earth left in the wake of a quake.

The Wenchuan Earthquake Memorial Museum was conceived of as an architectural landscape and situated in Wenchuan County, the epicenter of the earthquake in the Sichuan Province.

Green roofs look unassuming in the landscape while rusted steal provides a ground-hued contrast in the cracks winding their way through the ruptured site. The effect is powerful, giving visitors the sense that they are walking in the actual voids left by the disaster.

The quake was responsible for an estimated 70,000 deaths and left tens of thousands missing. The museum complex was created by the faculty of Tonji University at the request of the Chinese government.

The sheer magnitude of such an event is impossible to capture in physical form, but this design aims to at least give a sense of the devastation and places for remembrance and quiet contemplation.

Showing dynamism: EOS 80D breaks new ground for Canon low ISO DR

22 Mar

Our testing shows that Canon’s EOS 80D features a sensor with greatly improved Raw dynamic range. The results appear to confirm the company has moved to a new sensor design with lower read noise.

Previous Canon sensors have conducted the analogue to digital conversion step away from the sensor, an approach that contributed noise that limited dynamic range at low ISO settings (while still allowing the excellent high ISO performance that Canon’s CMOS chips built a reputation with). The sensors in the EOS 80D and EOS-1D X Mark II appear to have an on-chip ADC design that conducts the conversion within the sensor, shortening the electronic path and preventing this noise building up. Let’s take a look at the 80D’s Raw DR performance in a couple of our studio tests.

Exposure Latitude

In this test we look to see how tolerant of pushing exposure the 80D’s Raw files are. We’ve done this by exposing our scene with increasingly lower exposures, then pushed them back to the correct brightness using Adobe Camera Raw. Examining what happens in the shadows allows you to assess the exposure latitude (essentially the dynamic range) of the Raw files.

Because the changes in this test noise are primarily caused by shot noise and this is mainly determined by the amount of light the camera has had access to, the results are only directly comparable between cameras of the same sensor size. However, this will also be the case in real-world shooting if you’re limited by what shutter speed you can keep steady, so this test gives you an idea of the amount of processing latitude different formats give.

$ (document).ready(function() { ImageComparisonWidget({“containerId”:”reviewImageComparisonWidget-19311969″,”widgetId”:327,”initialStateId”:2216}) })

As you can see, the 80D is contributing less noise to its images than the 70D did, and this difference will be evident when you try to pull shadows up. It isn’t quite a match for the Nikon D7200$ (document).ready(function() { $ (“#imageComparisonLink2211”).click(function() { ImageComparisonWidgetLink(2211); }); }), but it’s enough that in real-world use, the files should have similar – if not slightly more – processing flexibility than the Canon EOS 5DS$ (document).ready(function() { $ (“#imageComparisonLink2215”).click(function() { ImageComparisonWidgetLink(2215); }); }), despite the latter’s larger sensor!

How to Use Figure to Ground Art Theory in Photography

27 Aug

What is figure to ground?

Why can you recognize an amazing photograph but struggle to produce one? Sure there are better cameras, advanced lighting techniques, and endless theories on composition, but very often the root of the problem lies in a simple concept that is often missed. In three words, we can sum up almost every cover of Vogue, National Geographic, and the New York Times – Figure to ground.

What is this term, what does it mean, and where does it come from? Figure to ground is one of the most important, and easily overlooked concepts, in photography. It’s not a rule, it’s not a law – it is a tool, and a very powerful tool at that. Once you learn it, it will become a part of every picture you take, no matter what type of camera you use.

If you were ever curious to see masterful use of figure to ground, try revisiting the photographers you already love like Steve McCurry, Richard Avedon, or Henri Cartier-Bresson. They all use it, some more elegantly than others. Figure to ground acts like an anchor in a photograph, holding the viewer’s eye inside the frame.

It goes by many names

Figure to ground has a multitude of names; subject to background, figure separation, foreground to background, and the list goes on. To simplify, figure to ground is the most descriptive and easiest to say, which is why artists have favored it for centuries.

A starting point

When it comes to describing visual tools in the written language, firm definitions are always a problem. Consider the following definition a starting point, not an immovable scientific definition.

Figure to ground is the visual relationship between objects and the space they occupy. We live in a 3D world, but your photographs are a 2D translation. When the third dimension of depth disappears, you end up with a problem that has plagued artists since they started scrawling on cave walls, how do you create a picture of the 3D world with only two dimensions?

Figure to ground allows your brain to determine shapes, sizes, distance and other optical illusions that exist in photography (it also applies to drawing, painting, and other 2D arts, but for this article the focus is on photography and how you can use it successfully).

Where did it come from?

The idea of figure to ground comes from drawing and painting. It forms the basic grammar of the visual language. Think about it, how can you see a shape on a piece of paper? It is visible because it is a black line on a white page. Seems obvious right, but what is that phenomenon called? It is called figure to ground. Imagine if we wrote in white ink on white paper – everything would be invisible.

The same thing applies to photographs. In order for your photograph to be legible, we must be able to see the object against the background. Artists have worked with this concept for centuries and developed elegant solutions to figure to ground as a deliberate, but subtle, technique for making pictures.

How to practice it

The first step in practicing figure to ground is to condition your eye by looking at good examples. If you want to be a great photographer, study master painters and how they use figure to ground. You can do this on the internet, in a book, or at a museum. Pick the one that is easiest for you.

TECHNIQUE 1: The Book

Pick up a book on a famous Renaissance artist, like DaVinci, Raphael, or Michelangelo. Setting aside whether you like their work or not, the way to use art to your advantage is to master the tools of successful artists, and apply them with your own unique touch. Lay a piece of tracing paper over the page and be sure to cover the whole picture. Can you still see the subject? If yes, there is good figure to ground. If the subject seems to disappear into the background then no, the figure to ground is weak.

TECHNIQUE 2: The Museum

If you wear glasses, this will be even easier. Go to a museum and find a painting. Following DaVinci’s advice on viewing distance, stand three times the height of the painting away from it (example: if the painting is five feet tall, stand 15 feet away). Now squint at the painting until it is all blurry, or simply remove your glasses. Can you still make out the major shapes in the painting. If yes, there is good figure to ground. If the subject seems to disappear into the background then no, the figure to ground is weak.

TECHNIQUE 3: The Computer

If you prefer to use technology, here is a technique you can do in Shotoshop. Pull a picture into Photoshop. Select Filter > Box Blur > set the pixels at 15 pts. You will end up with a blurry version of the picture. Can you still make out the major shapes in the painting? If yes, there is good figure to ground. If the subject seems to disappear into the background then no, the figure to ground is weak.

TECHNIQUE 4: Your Photography

Try any of the techniques above with your own photographs. If there is not strong figure to ground in your picture, play closer attention to the backgrounds when you shoot.

Camouflage

What if you never learn figure to ground, what will happen? Will it be impossible for you to ever make a good picture? No, of course not. But when you understand why some pictures work better than others, and what tools to use at the right time, you will enjoy photography much more. It relieves the anxiety of, “Will I get the shot?”. When you have a toolbox full of resources, it becomes easier to create consistently powerful pictures.

If you would like to know what the opposite of figure to ground is, look no further than camouflage. Camouflage is designed to obscure objects in space. It is the direct opposite of figure to ground. If the goal is to blend in, then use camouflage – if the goal is to pop out, use figure to ground. It is your choice.

Tools are not rules

Photography is an artistic expression. It might be your break from everyday life, the pressures of work, or the hidden talent you want to explore. Whatever role photography plays for you, the idea to take away is that photography is not a rule book. BUT – and this is a big BUT, there are tools involved. You can use a tool the way it was intended and achieve amazing things, or you can spend your life using a chisel as a fork and wonder why eating is so painful.

Think of your photography like a toolbox; it might have a hammer, a chisel, a screwdriver and a wrench. You might use more than one tool at a time, and all tools will not be used for every job. Your role as the photographer is to know how to use each tool at the appropriate time to reach the desired effect. Otherwise you might end up hammering screws and painting nails.

Developing subtlety

Where do you go from here? Here’s an assignment that will be very helpful:

1. Find 20 examples of figure to ground in paintings
2. Find 20 examples of figure to ground in photography
3. Go take 10 pictures of light figures on a dark ground
4. Go take 10 pictures of dark figures on a light ground

Once you practice this enough it will become like a reflex. Please share your comments and images below.

Hole in the Ground: 5 Ideas to Fill Downtown Chicago Spire Void

01 Apr

[ By WebUrbanist in Architecture & Cities & Urbanism. ]

chicago spire

Designed by a world-famous architect, the Chicago Spire was set to be the second-tallest building in the world, but now that plans for its construction have been abandoned local firms are stepping up to suggest novel ways to reuse the voided project’s remnant space.

chicago spire void

Submitted to Chicago Magazine, these various schemes to replace the failed vision of Santiago Calatrava are bound to resonate with residents, created by and for the local population and context, featuring everything from underground performance spaces and wildlife sanctuaries to urban lighthouses and swimming holes.

chicago spire amphitheater

One proposal invites people to occupy the hole in the form of a seven-story underground amphitheater, allowing loud late-night events to operate freely in the subterranean space. This Underground Amphitheater scheme by SPACE Architects + Planners is likened to a headphone buried in the Earth, its emissions audible when you get up close and keep an ear to the ground.

chicago spire bird sanctuary

A radically different tactic suggests a steel aviary trellis surrounded by native vegetation. serving as a stopping point and bird-watching spot for migratory species. Dubbed Birds in Horto by designer Hoerr Schaudt, the void in this case remains inaccessible, a mystery at the center of a larger natural park space. “A 10-story spiraling trellis of steel and wood serves as armature for nesting and perching, while a surrounding thicket of native plants, such as crabapple and plum trees, offers sustenance. An elevated walkway lets you observe the warblers, cardinals, and sparrows without disturbing them.”

While the specific sizes and subjects vary, a common thread is found in their site-specific nature and detailed drawings – each figure or set thereof participates directly in its surroundings.

“From break dancing to skateboarding to rock climbing to becoming a father, all of these things have helped define my character. For me, it’s just about revisiting those moments in a way that’s familiar. I’ve always appreciated seeing architecture and nature in a different light.”

“As a skater, the tar banks behind a local supermarket, a flight of stairs, a parking block, a drainage ditch, a handrail, a wall – they all present possibilities for interaction and fun in ways they weren’t intended to be used.”

A Collection of Low to the Ground Images

15 Nov

Creating an original image can sometimes be challenging. One of the best ways to do it is to change up your camera angle or perspective. Getting up high and looking down is one method, another is crawling around in the dirt to get a worm’s eye view. As you can imagine the name comes from approximating the view a worm would have from his angle on the ground.

Being low to the ground will set your images apart because the average person doesn’t see that way, or take photos from down there. It can also mean looking straight up. Here are some worm’s eye view images to give you some ideas:

Getting off the ground: Cheap drones for photography

03 Jul

With the popularity of drone photography ever increasing, curious hobbyists may be looking for a way to try it out without spending a lot. It’s not the most expensive hobby you could pick, but $ 1000 for a DJI Phantom II and a GoPro Hero3+ is about the same cost as a mid-range camera and lens. Low-cost drones with built-in cameras seem like a great option for the curious. But do the price benefits outweigh the inevitable image quality and usability tradeoffs that come with a cheaper quad?
