Sony sells half of its Olympus stake

02 Apr

Sony is selling half its stake in Olympus to investment bank JP Morgan to free up cash for ‘strategic investments,’ the company has announced. Sony bought a 10% stake in the medical and camera company in 2012, primarily to gain access to the global medical market to which it hoped to apply its sensor, 3D and display technologies. At the time Olympus’s future was in doubt, following revelations that it had misstated its accounts having been secretly redirecting money to pay off long-standing debts that has been hidden from investors. Read more

Tips for Photographing a Lunar Eclipse

02 Apr

_MG_5566-MWhile some obscure astronomical events get over-hyped, a total lunar eclipse is always a crowd-pleaser. It is easy to observe and photograph, even among the bright lights of the big cities. April’s Easter Lunar Eclipse (2015) is visible from North America, across the Pacific to Australia, and eastern parts of Asia. The photography advice below will also serve the rest of the world well in September when an eclipse is visible to those who miss out on this one.

Eclipse Details for Saturday April 4th, 2015

A lunar eclipse occurs when the alignment of the moon’s orbit is just right, taking it inside Earth’s shadow at the time of full moon, when the moon is opposite the sun. This total eclipse occurs on Saturday April 4th, 2015, in the morning for observers in the Americas, and the evening for those in Australia and Asia. In total, this eclipse lasts for three and a half hours but totality, where the moon is fully inside our shadow, only lasts for around five minutes.

Because the moon only grazes into the shadow, this eclipse is likely to be a little brighter than usual, and the color more orange than red. For people in eastern Canada and the United States, as well as western parts of South America, the moon will set before the total eclipse begins, but you will have the opportunity to create unique images of the moon setting partially eclipsed.

Visit in-the-sky.org for event times in your area. Change your location on the right hand side if the automatic selection is incorrect.

Photographing a Lunar Eclipse

There are two main approaches to photographing a lunar eclipse using just a DSLR and a tripod, excluding more complex approaches with telescopes and tracking mounts.

  1. You can get in as close as possible with a telephoto lens to capture detail of the changing partial, and total phases of the eclipse.
  2. Create wide-field and composite images showing the stages of the eclipse as the moon moves through the sky.

Wide-field Eclipse Composites

Nine exposures of the moon each 1/90 sec, f/8, ISO 200.
Images stacked is PS using lighten blending mode with one 2 second exposure of the foreground.

The moon moves across the sky at approximately 15 degrees per hour or 50 degrees over the full duration of the eclipse. You need a wide angle lens around 18mm focal length (28mm on a full frame camera) to capture all the stages of the eclipse in one field of view. An alternative is to frame up part of the eclipse with a longer focal length about 50mm (80mm on a full frame camera) like the image above which shows the partial stages in more detail.

In the northern hemisphere, the moon (like the sun) moves from left-to-right through the sky. So at the start of the eclipse, position the moon in the left side of the frame leaving it room to move across the image during the eclipse. Reverse that advice in the southern hemisphere. Night sky planetarium Apps such as Stellarium and SkySafari (iOS only) allow you to visualize the path of the moon through the sky to help plan your framing.

Telephoto Eclipse Images

With a moderate telephoto lens you can get nice detail of the changing stages of a lunar eclipse. During the partial stages the brightness of the moon allows for very short exposures, so trailing it should not be a problem, although you will need a sturdy tripod and use mirror lock-up to reduce vibration.

During totality, the Moon’s brightness greatly reduces, however this eclipse will be a little brighter than usual. Aim for exposures of around one second with the aperture wide open, and push the ISO as much as you need to, being careful not to blow the highlights on the brighter edge. You should be able to capture images like this one below, which is an example of what you can do even with regular affordable cameras (although nice lenses do help).

Eclipse at Moonset

In the eastern United States and Canada, and the western half of South America, the moon will set during the partial stages before total eclipse. Through central areas the moon will set while totally eclipsed which will make it much dimmer than a normal moonset and potentially hard to see amongst bright city lights. In the western half of North America you get to enjoy the partial phases leading up to, and including the total eclipse, then capture the moon setting as the partial phases reverse at the end of the eclipse.

You can use apps and software like The Photographers Ephemeris (Android/iOS) and Photo Pills (iOS only) to plan the alignment of the moon against landscape features as it rises or sets. Australian photographer Colin Legg captured this shot of the moon rising during an eclipse last year. An astronomer would immediately recognize the unusual configuration – a crescent moon can normally only appear in a twilight sky in the same direction as sunrise or sunset. Here the crescent moon appears amidst the beautiful shading of Earth’s shadow and The Belt of Venus, opposite where the sun set about 15 minutes earlier. Similar images before sunrise will be possible across North and South America during April’s lunar eclipse.

Post-Processing Tips for Overcoming Beginners Acts of Omission

02 Apr

In an old dressmaking shop in Paris, a master-tailor has finished stitching a bridal gown. He is eager to show it to the world, but he knows that the job is not yet done. He has a few thoughts passing through his mind, and he has to make sure that the dress is presentable before the bride arrives. He tells himself that these threads dangling from here and there need to be trimmed, the ruffles need to be neatened, and the seams still need to be pressed. The master in him criticizes the dress until the tailor in him fixes the final details.

When it comes to photography, the story is no different. You must lose ownership of your image for a few seconds, and look at your own work with a fine-tooth comb. As beginners, we often rush to upload or print our photos, eager for appreciation and likes from others.

I have also been impatient in this way, though with time, I have now made it a habit to review my image critically at the end of post-processing. Here are some tips I hope that will help you taking your post-processing experience to the next level and pick up on some things that beginners often miss. I use Adobe Lightroom and Photoshop, so I will be talking about both where applicable.

Crooked images

There is nothing more embarrassing than your client telling you that the photo is a bit askew. Once spotted, it is an eyesore that will forever jar when you look at your image. It is not easy to judge tilted images when it comes to mountains and forests, but landscapes are also more forgiving when it comes to a tilt. With seascapes, however, one needs to ensure that the sky meets water on the perfect horizontal for a harmonious and balanced image. Similarly, check the angles of your doorways and buildings, that they are aligned appropriately. Adobe Lightroom has a useful Straighten tool, as well as options in Photoshop.

Skew Horizon

A crooked horizon is not always obvious; verify it using the proper tools.

Spots

Zoom-in and inspect your photo to make sure that there are no spots. Dried water droplets and dust become more visible when you increase the contrast of colors in your post-processing. Adobe Lightroom has a Spot Removal tool, and Adobe Photoshop also provides various ways to remove spots from your image.

Spots

Imagine printing a large image with these spots. These are very visible.

Chromatic aberration

Chromatic aberration, or color fringing, often happens around the edges of objects in your images. Why this happens is a technical topic on its own related to your lens, but what you need to know is that modern tools help remove this problem. Adobe Lightroom has a Remove Chromatic Aberration tool that you can use to overcome this issue.

Chromatic_Aberration

With just one click, I was able to remove the color fringe from the edges.

Barrel distortion

Barrel distortion is associated with wide angle lenses. It causes your image to look more like a sphere. You might get away with it if the elements in your scene are uneven, and not particularly familiar to the eye. However, you need to be aware that the wider your focal length, the more distortion your image will have. Adobe Lightroom allows you to remove barrel distortion using the Lens Corrections feature. In the following image, people standing on each side of the image have elongated faces. I did not, of course, include this in the bridal album!

Raaiqah & Taariq Wedding, November 2014

Unwanted objects

Look for unwanted objects in the scene. Remove shopping bags, cans, tins, ships on the horizon, and even people if they are not desired in the scene. I use Adobe Photoshop’s Content Aware fill tool to achieve the desired results.

Image in black and white

Before and after post-processing, I usually check my images in black and white. By not allowing yourself to be distracted by colours, this is a good way to see if an image is flat. I do this for several reasons. Some images are just meant to be black and white, especially the ones in which the colour adds little by way of interest, and in fact may distract from the subject. You might also want to turn an image into black and white because the sky is overexposed, in this way salvaging, rather than discarding the image altogether. By converting an image to black and white, sometimes unwanted distracting elements in the background of your image can be de-emphasized, with some additional light adjustment (e.g. a person standing behind your main subject in a portrait).

Color_Landscape BW_Landscape

Black and White allows you to appreciate the landscape with emphasis on the harmonies and lines rather than on the colours.

Color_Portrait BW_Portrait

In black and white, the background is not as distracting.

Tip: Walk away

Once you have finished editing your image (or a batch of images), step back and give review it full screen. Turning off the room lights and leaning back is a good idea. Without the mouse and the keyboard in my reach, I can think about the image critically. I sometimes even walk away and let the image lie there for some time before returning for a fresh approach.

Whether you are a beginner or a professional, after putting effort into post-processing, you tend to think that you have done enough to make the image ready. You focus on certain areas too much, and your mind forgets to tell you that you need to look in other areas to see if the image is balanced and harmonious. So, take your time and allow the image to fully absorb without patience in the post-processing phase. A lovely image can be converted into a magical one by proper processing.

Though these steps may sound pedantic, a good image needs loving care.

I hope these tips are helpful. Your feedback and comments are welcome.

My Most Unique Photo of Yosemite Yet

01 Apr

Yosemite Tunnel View

After spending days researching one of my favorite photo locations on Flickr, Instagram and 500px and then tracking down the almost exact location through shared camera GPS data I drove 5 1/2 hours to capture this amazing Yosemite view that is destined to be a centerpiece of my landscape portfolio. Just when I thought I was the only person who might have thought of capturing this unique vantage point I ran into my friend Colleen Miniuk-Sperry as I was leaving. Apart from some brief small talk as I left, my friend Colleen took my spot in the photographer lineup (after all it was standing room only) to capture her own unique take of this iconic view. I highly recommend seeing her photo on her blog You Can Sleep When You’re Dead.

Nikon D7200 real-world samples gallery posted

01 Apr

The Nikon D7200 improves over its predecessor in one important way, offering a greatly improved buffer. Other improvements are more subtle, but more sensitive AF and an improved video specification make the D7200 a more capable camera than the model which came before it. We’ve had a D7200 for a few days, and wasted no time pairing it with Sigma’s excellent 18-35mm F1.8 A to get some real-world samples. Click through to see more

2,300 Floating Flowers: Interactive Garden Makes Way as You Walk

01 Apr

[ By WebUrbanist in Art & Installation & Sound. ]

floating plants experienced together

Responding to the movements of visitors passing through the space, this immersive work of installation art puts you in a private bubble in the midst of dense hanging garden – except this remarkable bubble that moves with you.

teamlab floating flower installation

The Floating Flower Garden by TeamLab, a Japanese art collective, is on display in Tokyo, having been extended due to popular demand. Suspended from above, the plants are pulled up or dropped down to both envelop visitors but also given them hemispheres of personal space amid the floating foliage.

floating flower art installation

The idea is to make each guest part of the installation, allowing them to separate from friends and experience it alone or to move in groups and see how the computer system responds in realtime.

floating solo alone forest

Meanwhile, the digital setup is not the only piece that changes things over time: “these flowers are alive and growing with each passing day. Each flower has a partner insect and the scent of the flowers becomes stronger at the time that the insect is most active, as a result the scent of the air in the garden space changes according to the time of day, morning, noon, and evening.”

floating walking bubble interactive

TeamLab believes technology elevates art, but their work also places into pre-modern knowledge and ancient ideas of spatial awareness originating in Japanese philosophy and religion, including Zen gardens. More from the artists: “When a viewer gets close to this flower-filled space, the flowers close to the viewer rise upwards all at once, creating a hemispherical space with the viewer at its center.”

floating garden immersive space

“In other words, although the whole space is filled with flowers, a hemispherical space is constantly being created with the viewer at its center and the viewer is free to move around wherever they want. If many viewers get close to one another, the dome spaces link up to form one single space. In this interactive floating flower garden viewers are immersed in flowers, and become completely one with the garden itself.”
