Sony boosts sensor output to meet strong demand

Imaging Resource - Mi, 23/07/2014 - 21:18
    It's a good time to be a sensor manufacturer, it seems. While camera sales have been hard-hit by the rise of smartphones, demand for image sensors is stronger than ever. (And that's especially true of stacked, backside-illuminated image sensors, a popular choice in smartphones where the tradeoff between camera module size and image quality makes them particularly useful.) An announcement today from Sony proves that point rather nicely. The company is once again planning to boost its stacked sensor production capacity, investing...

Learn how to use HDR to create natural looking photos in this B&H educational video

Imaging Resource - Mi, 23/07/2014 - 19:13
When photographing a scene with strong contrast, such as a landscape during the morning or evening light, a cityscape in the afternoon, or an interior scene with bright light coming in through the windows, most digital cameras' sensors are uncapable of capturing the full dynamic range of the scene. This leads to a loss of detail either in the highlight or in the shadows. The most common technique to overcome this natural limit of digital sensors is HDR photography. By taking multiple images of the same scene with varying exposures, these can be merged by...

Using 50 Canon EOS 1D X cameras to create a ten second bullet time action sports clip

Imaging Resource - Mi, 23/07/2014 - 14:37
    Ever since the 1999 sci-fi action movie "The Matrix," the so-called "bullet time" technique has become immensely popular in all kinds of visual productions. By arranging multiple cameras around a subject and triggering them at the same time, the technique allows to create a virtual camera movement around the scene while at the same time freezing the action. When the Swiss TV production company DokLab was approached by public broadcaster SRF about a documentary on extreme sports, their client asked them not to produce a...

Ten CSS One-Liners to Replace Native Apps

A List Apart - Mi, 23/07/2014 - 13:30

Håkon Wium Lie is the father of CSS, the CTO of Opera, and a pioneer advocate for web standards. Earlier this year, we published his blog post, “CSS Regions Considered Harmful.” When Håkon speaks, whether we always agree or not, we listen. Today, Håkon introduces CSS Figures and argues their case.

Tablets and mobile devices require us to rethink web design. Moused scrollbars will be replaced by paged gestures, and figures will float in multi-column layouts. Can this be expressed in CSS?

Paged designs, floating figures, and multi-column layout are widely used on mobile devices today. For some examples, see Flipboard, the Our Choice ebook, or Facebook Paper. These are all native apps. If we want the web to win on these devices (we do), it’s vital that designers can build these kinds of presentations using web standards. If web standards cannot express this, authors will be justified in making native apps.

Over the past years, I’ve been editing two specifications that, when combined, provide this kind of functionality: CSS Multi-column Layout and CSS Figures. I believe they are important to make sure the web remains a compelling environment for content providers.

In this article, I will demonstrate how simple it is to write CSS code with these specs. I will do so through 10 one-liners. Real stylesheets will be slightly longer, but still compact, readable, and reusable. Here are some screenshots to give you a visual indication of what we are aiming for:

Building a page

The starting point for my code examples is an article with a title, text, and some images. In a traditional browser, the article will be shown in one column, with a scrollbar on the right. Using CSS Multi-column Layout, you can give the article two columns instead of one:

article { columns: 2 }

That’s a powerful one-liner, but we can do better; we can make the number of columns depend on the available space, so that a narrow screen will have one column, a wider screen will have two columns, etc. This is all it takes to specify that the optimal line length is 15em and for the number of columns to be calculated accordingly:

article { columns: 15em }

To me, this is where CSS code morphs into poetry: one succinct line of code scales from the narrowest phone to the widest TV, from the small print to text for the visually impaired. There is no JavaScript, media queries, or expensive authoring tool involved. There is simply one highly responsive line of code. That line is used to great effect to produce the screenshots above. And it works in current browsers (which is not yet the case for the following examples).

The screenshots above show paged presentations, as opposed to scrolled presentations. This is easily expressed with:

article { overflow: paged-x }

The above code says that the article should be laid out as pages, stacked along the x-axis (which, in English, is toward the right). Browsers that support this feature must provide an interface for navigating in these pages. For example, the user may reach the next page by making a swiping gesture or tilting the device. A visual indication of which page you are reading may also be provided, just like scrollbars provide a visual indication in scrolled environments. On a tablet or mobile phone, swiping to the next page or document will be easier than scrolling.

Images

Adding images to the article creates some challenges. Lines of text can easily be poured into several columns, but if figures are interspersed with text, the result will be uneven; because images are unbreakable, they will cause unused whitespace if they appear at a column break. To avoid this, traditional paper-based layouts place images at the top or bottom of columns, thereby allowing other text to fill the whitespace. This can naturally be expressed in CSS by adding top and bottom to the float property. For example:

img { float: bottom }

The bluish harbor images in the screenshots above have been floated to the bottom of the page with this one-liner. CSS is used to express something that HTML cannot say; it is impossible to know how much textual content will fit on a screen in advance of formatting. Therefore, an author cannot know where to insert the image in the source code in order for it to appear at the bottom of the column. Being able to float figures to the top and bottom (in addition to the already existing left and right) is a natural extension to the float property.

Spanning columns

Another trick from traditional layout is for figures to span several columns. Consider this newspaper clipping:

Used with permission from the Bristol Observer

In the newspaper article, the image on the left spans two columns and is floated to the bottom of the columns. The code to achieve this in CSS is simple:

figure { float: bottom; column-span: 2 }

HTML5’s figure element is perfect for holding both an image and the caption underneath it:

<figure> <img src=cats.jpg> <figcaption>Isabel loves the fluffy felines</figcaption> </figure>

The newspaper article also has a figure that spans three columns, and is floated to the top right corner. In a previous version of the CSS Figures specification, this was achieved by setting float: top-corner. However, after discussions with implementers, it became clear that they were able to float content to more places than just corners. Therefore, CSS Figures introduces new properties to express that content should be deferred to a later column, page, or line.

Deferring figures

To represent that the cat picture in the newspaper clipping should be placed at the top of the last column, spanning three columns, this code can be used:

figure { float: top; float-defer-column: last; column-span: 3 }

This code is slightly less intuitive (compared to the abandoned top-corner keyword), but it opens up a range of options. For example, you can float an element to the second column:

.byline { float: top; float-defer-column: 1 }

The above code defers the byline, “By Collette Jackson”, by one. That is, if the byline would naturally appear in the first column, it will instead appear in the second column (as is the case in the newspaper clipping). For this to work with HTML code, it is necessary for the byline to appear early in the article. For example, like this:

<article> <h1>New rescue center pampers Persians</h1> <p class=byline>By Collette Jackson</p> ... </article> Deferring ads

Advertisements are another type of content which is best declared early in the source code and deferred for later presentation. Here’s some sample HTML code:

<article> <aside id=ad1 src=ad1.png> <aside id=ad2 src=ad2.png> <h1>New rescue center pampers Persians</h1> </article>

And here is the corresponding CSS code, with a one-liner for each advertisement:

#ad1 { float-defer-page: 1 } #ad2 { float-defer-page: 3 }

As a result of this code, the ads would appear on page two and four. Again, this is impossible to achieve by placing ads inside the text flow, because page breaks will appear in different places on different devices.

I think both readers and advertisers will like a more page-oriented web. In paper magazines, ads rarely bother anyone. Likewise, I think ads will be less intrusive in paged, rather than scrolled, media.

Deferring pull quotes

The final example of content that can be deferred is pull quotes. A pull quote is a quote lifted from the article, and presented in larger type at some predetermined place on the page. In this example, the pull quote is shown midway down the second column:

Here’s the CSS code to express this in CSS:

.pullquote#first { float-defer-line: 50% }

Other types of content can also be positioned by deferring lines. For example, a photograph may be put above the fold of a newspaper by deferring a number of lines. This will also work on the foldable screens of the future.

Pull quotes, however, are an interesting use case that deserve some discussion. A pull quote has two functions. First, it presents to the reader an interesting line of text to gain attention. Second, the presentation of the article becomes visually more varied when the body text is broken up by the larger type. Typically, you want one pull quote on every page. On paper, where you know how many pages an article will take up, it is easy to supply the right number of pull quotes. On the web, however, content will be reformatted for all sorts of screens; some readers will see many small pages, other will see fewer larger pages. To ensure that each page has a pull quote, authors must provide a generous supply of pull quotes. Rather than showing the extraneous quotes at the end of the article (which would be a web browser’s instinct), they should be discarded; the content will anyway appear in the main article. This can be achieved with a one-liner:

.pullquote { float-policy: drop-tail }

In prose, the code reads: if the pull quote is at the tail-end of the article, it should not be displayed. The same one-liner would be used to extraneous images at the end of the article; authors will often want to have one image per page, but not more than one.

Exercises

The studious reader may want to consult the CSS Multi-column Layout and CSS Figures specifications. They have more use cases and more knobs to allow designers to describe the ideal presentation of figures on the web.

The easiest way to play with CSS Figures is to download Opera 12.16 and point it to this document, which generated the screenshots in Figure 1. Based on implementation experience, the specifications have changed and not all one-liners presented in this article will work. Also, Prince and AntennaHouse have partial support for CSS Figures—these are batch formatters that output PDF documents.

I’d love to hear from those who like the approach taken in this article, and those who don’t. Do you want this added to browsers? Let me know below, or request if from your favorite browser (Firefox, Chrome, Opera, IE). If you don’t like the features, how would you express the use cases that have been discussed?

Pages and columns have been basic building blocks in typography since the Romans started cutting scrolls into pages. This is not why browsers should support them. We should do so because they help us make better, more beautiful, user experiences on mobile devices.

Nikon V3 Shooter’s Report I: Should this super-speedy mirrorless persuade you to give the 1-series another look?

Imaging Resource - Mo, 21/07/2014 - 22:12
    Ever since Nikon's 1-series launched with the V1 -- predecessor of today's Nikon V3 -- way back in 2011, the company has taken flak for choosing a smaller image sensor than its main rivals, most of whom have opted for Four Thirds or APS-C type sensors in their mirrorless cameras. Nikon has stuck to its guns, though, firm in its belief that the 1-series cameras offer important advantages over the larger-sensored competition. The Nikon V3 hones the flagship 1-series design with changes throughout, aimed at playing to the strengths...

    Canon turned a few heads back when it released the original PowerShot G1 X: the industry's first compact, large-sensor camera to offer a zoom lens. The 1.5"-type sensor was leaps and bounds larger than what's inside the typical compact camera, and it was married with Canon's popular PowerShot G-series build, ergonomics and functionality. While Canon got a number of things "right" with that camera, namely great image quality, very good optics, and twin dials that resemble DSLR functionality, it had some rough edges with slower than...
