BigDelta’s structural strategies and resulting home shapes are informed by a breed of wasp that constructs mud homes as well as a long human tradition of creating earthen dwellings.

Building with water, dirt, clay and plant fibers taps into a set of plentiful organic resources, reduces environmental impacts, obviates the cost of and need to ship materials and provides naturally robust and insulated housing shells.

This larger model follows a smaller Delta prototype used to execute a series of complex geometric structures at reduced size, testing the technology and materials.

The design aims to address a growing housing crisis: “by 2030, international estimates foresee a rapid growth of adequate housing requirements for over 4 billion people living with yearly income below $ 3,000. The United Nations calculated that over the next 15 years there will be an average daily requirement of 100.000 new housing units to meet this demand.”

A Beginner’s Guide to Choosing Shooting Mode

22 Sep

Even the most seasoned veteran photographer may use a pre-programmed mode occasionally in order to concentrate immediately on a shot rather than take the time to calculate exposure and miss the opportunity for the great image. But if you are a beginner at photography or want to advance your photography skills beyond the use of Auto mode, begin by adventuring away from the green box.

When you are setting up your camera to capture an image, there are four basic results to consider: wide depth of field, shallow depth of field, motion blur or freeze motion. How do you know which mode to use to control these basics of photography? Let’s take a look.

Nikon-Canon-mode-dail

Auto (Green box)

In Auto mode, your camera will automatically set the shutter, aperture, ISO, white balance, and even the pop-up flash for you.

Advantages: This is a great option for beginners with a digital camera – but don’t become dependent on it! Only use it until you learn to take control of your camera.

Disadvantages: In certain lighting conditions the auto settings may produce undesirable images. For instance, a portrait that is heavily back-lit might just produce a silhouette. In low-light, you may end up with blurry and grainy images; also in low-light, the camera may choose to fire the flash to give more light and many camera models don’t provide a way to disable the flash if you don’t want it.

When to use: Any time you want to use your camera just as a point and shoot camera, this is your mode.

This portrait was intentional shot into the sun in Auto Mode. While the camera did a decent job with exposure, it might be a 1/2 stop under exposed. Auto exposure settings choose by the camera are 1/250th of a second at f/6.3 with ISO of 100. while the shutter speed and ISO are good, a wider aperture would have lessened the DOF and made the background less distracting.

This portrait was an intentional shot into the sun in Auto mode. While the camera did a decent job with exposure, it is a 1/2 stop under-exposed. The auto exposure settings chosen  are 1/250th of a second at f/6.3 with ISO of 100. While the shutter speed and ISO are acceptable, a wider aperture would have lessened the DOF and made the background less distracting.

Program (P)

In Program mode, your camera will automatically set the shutter speed and aperture, but will allow you to choose ISO, white balance, exposure compensation and flash options.

Advantages: This is a great next step for a beginner who wants to take a little more control of their camera and improve their images.

Disadvantages: As in Auto mode, certain lighting conditions may lead to unpredictable results, due to the partial automatic settings which leave some results to chance.

When to use: Use this mode if you want to take a good first step to ultimately taking complete control of your camera’s options.

Shutter Priority (TV – Canon) (S – Nikon)

In Shutter Priority mode, you select the shutter speed and ISO and the camera will automatically choose the proper f-stop for what it determines to be the correct exposure.

Advantages: Great for controlling freeze action and motion blurring of moving objects.

Disadvantages: In this mode you have control of your shutter speed, so you must be careful that your camera can choose an f-stop to give you a proper exposure. The type of lens you have available to use comes into play here. Most cameras can shoot at a very fast shutter speeds, but if your lens doesn’t have a large enough aperture to match that shutter speed the resulting image will be under-exposed.  For example, if you are shooting with a shutter speed of 1/4000th of a second, and the proper exposure for the speed of the subject requires an f-stop of f/2.8, but the widest opening on your lens is f/3.5, the image will be under-exposed.

When to use: Use this mode when you want to control the motion of the object you are photographing. Use a fast shutter speed if you want to freeze the motion or use a slow shutter speed if you want to blur the motion. This mode is also useful when using large mm lenses where you need to set a fast shutter speed to avoid blurred images due to camera shake.

Choosing shutter priority and setting shutter to 1/8th of a second to blur the water.

Shutter priority with a shutter to 1/8th of a second was used to blur the fast moving water.

Here are some suggested shutter speeds for Shutter Priority:

  • Freeze very fast motion – 1/3000th of a second
  • Athletes in motion – 1/500th to 1/1000th of a second
  • Birds in flight – 1/1000th to 1/2000th of a second
  • People walking – 1/250th of a second
  • Panning moving objects – 1/30th to 125th of a second
  • Blurring fast moving water – 1/8th of a second
  • Blurring slow moving water – 1/2 to 1 secondshutter

Aperture Priority (AV – Canon) (A – Nikon)

In Aperture Priority mode, you select the aperture and ISO and the camera will automatically choose the proper shutter speed for what it determines to be the correct exposure.

Advantages: Other than Manual mode (next paragraph), Aperture Priority is the most popular shooting mode photographers use, mainly because it controls what is in focus in your image. And in most cases the item you have in focus is the element that will make or break the success of your image.

Disadvantages: In low-light situations your camera may choose a very slow shutter speed that will produce a blurry image, either because of movement by the subject or camera shake.

When to use: Use this mode when you want to control the Depth of Field (DOF) of your image. The larger the aperture the more light reaches your camera’s sensor and the shallower the DOF. Reversely, the smaller the aperture the less light reaches your camera sensor and the deeper the DOF. Beware that changing your aperture will also affect your shutter speed. More light from large apertures requires a faster shutter speed and less light from small apertures requires a slower shutter speed.

Using Aperture Priority to set a larger aperture to increase DOF

Aperture Priority to set a larger aperture to increase DOF.

Here are some suggested f-stops for Aperture Priority:

  • Landscapes -f/8 or higher for more DOF
  • Portraits – Large aperture  (f/2.8) for shallow DOF to blur the background
  • Macro – f/8 or higher for more DOFaperture

Manual (M)

Manual mode allows you to change both the shutter speed and aperture settings independently from each other. No settings will be automatically set by the camera. Your camera’s built-in light meter will guide you on the exposure it determines to be correct, but you have complete control to adjust the shutter and aperture separately to get the exposure you determine to be correct for the image you are creating. Before you use the manual mode it is recommended that you have an understanding of the exposure triangle (shutter speed, aperture and ISO) and how each will affect your final image.

Advantages: This mode gives you complete creative control of the image you are capturing.

Disadvantages: While this mode has many creative advantages, you must be careful to always check the exposure with every image, especially when shooting in fast changing lighting conditions.

When to use: After you have learned to use this mode and learned the effects and results of the settings and how they work together, you will use this mode almost every time.

Here Manual mode was used to control the DOF and to use a slow shutter speed to blur the waterfalls.

In Manual mode, a small aperture was used to control the DOF while also setting a slow shutter speed to blur the motion of the waterfall.

Scene Modes

Scene mode is very similar to Auto mode. You choose the scene you are shooting and the camera will choose settings for you optimized for that scenario. Different camera models may have different scene modes, but listed here are some of the most popular:

  • Sports – Camera will increase ISO and use a fast shutter speed to capture fast action.
  • Landscape – Camera will use a small aperture to maximize the DOF; flash may also be disabled.
  • Portrait – Camera will use a large aperture to  throw the background out of focus. Some models of cameras will also use face recognition in this mode.
  • Macro – Camera will choose small aperture to give as much DOF as possible.

Advantages: As with the Program mode, these Scene modes are a beneficial starting point for beginners and will often give a better result than shooting in Auto mode.

Disadvantages: While these settings can produce desirable images at times, the results may vary and will not be reliable.

When to use: While these scene modes may be a step up from Auto mode for beginners, use these options as a starting point to learn your camera, understand its workings, and upgrade your photography skills.

Aperture-Shutter

 

So which mode is the best?

It is completely up to you which mode you feel most comfortable using. But if you are using the Auto, Scene or Program modes and you want to improve your photography, learning how to set exposures using the exposure triangle of shutter, aperture and ISO will help you make the best possible choices to create better images.  The two most popular modes used by professional photographers are Manual and Aperture Priority. Remember, professionals were once beginners too. Enjoy your camera experiences, no matter which mode you choose!

Abandoned Ship: Artist Paints Figure Onto Floating Ruins

22 Sep

[ By Steph in Art & Street Art & Graffiti. ]

ship graffiti 2

Hawaiian artist HULA paints the head and arm of a floating woman onto the rusted steel surface of an abandoned ship, all while balancing on a surfboard. The woman’s face appears and disappears with the tides, the rising water sometimes only revealing her hand. This large-scale guerrilla mural is the latest waterside work to be completed by HULA, who’s known for his unusual balancing act technique.

Otherwise known as Sean Yoro, the Oahu-born, NYC-based artist gained attention this summer for translating his oil paintings on canvas to urban surfaces located along canals or other bodies of water. HULA’s favorite subjects are bathing women, painted with photorealistic detail onto crumbling concrete.

The artist was inspired to create ‘Ho’i Mai’ (which translates to ‘Come Back’) on the stern of a half-sunken ship off the Hawaiian coast after watching the water rise and fall as the tides change throughout the day.  Floating out to work alongside the ship on his paddle board, HULA hand-painted the image without the apparent use of a projector or, in fact, anything other than a few cans of paint and some brushes.

Yoro hopes to turn the ship into a public work of art rather than just a forgotten vessel left to slowly sink into the water over the decades. The painting won’t last forever, though, as the artist uses traditional oil paints knowing they won’t stand up to the elements for long.

“I use it in a traditional old masters’ technique, mixing both loose brushwork with very tight strokes of sharp lines,” he told CNN. “I’m always trying to make the paint have a juicier texture to really help the portrait come alive. Oil paint outdoors definitely isn’t the best and it doesn’t last nearly as long as acrylics, but I kinda like that my figures have their own lifespan.”
