撮影したあとから手前にも奥にもフォーカスできる Lytro カメラが、アップデートで視差効果 " Perspective Shift " と新フィルタ " Living Filter " に対応します。

パースペクティブシフトは、ドラッグや傾き操作で写真の視点を微妙にずらす機能。範囲は狭いものの、映画の特殊効果のバレットタイムのように、切りとられた時間のなかで視点を動かせます。

リビングフィルタのほうは、カラーやモザイクといった画像フィルタに奥行きの要素を加えたもの。言葉で説明するより続きに掲載した動画デモをごらんください。

Perspective Shift のデモ。Lytro は主レンズと撮像素子のあいだに多数のミニレンズ群(Plenoptic Lens) を挟んだ構造で、主レンズに入るあらゆる光の方向まで記録するカメラ。撮影したあとから任意の場所に焦点を合わせられることが売りですが、同時にこのような視差効果にも応用できます。

Lytro で撮った写真はインタラクティブなままウェブやSNSに貼りつけられるため、撮影者以外でも写真のいろいろな場所に焦点をあわせたり、マウスでぐりぐりと視点を動かして見ることが可能です。




もうひとつは「リビングフィルタ」。画像フィルタとしてはモノクロ化やモザイク化、線画効果など一般的なものですが、視差から得た奥行き情報を使って適用範囲を自動的に決められることがポイント。

たとえば注目したい被写体だけをカラーにして残りをモノクロにしたり、フォーカスした前景と背景のあいだにガラスを挟んだように見せるなど。

Photoshopで上手に範囲選択して奥行きごとに切り分けて~といった作業の必要なく、クリックした場所に応
じてフィルタがかかります。

Perspective Shif / Living Filter とも、Lytro カメラ本体ではなくデスクトップソフトウェア側のアップデートとして提供されます。そのため、これまでに Lytro で撮った写真に新規のフィルタや効果を適用することも可能。アップデートは12月にリリース予定です。

Lytro Unveils Perspective Shift and Living Filters
for New Ways to Experience Living Pictures


Mountain View, Calif. – November 15, 2012 – Lytro Inc., creator of the world's first consumer light field camera, announced today it will unveil a new light field technology capability for the Lytro camera with Perspective Shift as well as new creative tools with Living Filters. These features will be available to customers starting December 4th via a free Lytro Desktop software update.

Perspective Shift lets Lytro photographers interactively change the point of view in a picture after it has been taken. On a computer or mobile device, viewers can move the living picture in any direction – left, right, up, down and all around. When pictures are shared to the web, Facebook and Twitter, friends can experience Perspective Shift without needing any special software. Perspective Shift also works retroactively on any light field pictures previously taken with a Lytro camera.

"By capturing the light field, the Lytro camera lets photographers achieve things that were never before possible. The first groundbreaking capability was focusing pictures after they were taken and now we are excited to offer Perspective Shift, which brings living pictures to life in an entirely new way," said Ren Ng, founder and executive chairman of Lytro.

"The new Perspective Shift from Lytro is fun and artistic! I've had a wonderful time running around with my Lytro camera to grab little scenes and bend them into this new way of seeing living photos. The idea that you can take any little scene and make it like interactive Matrix-bullet-time is really cool," said Trey Ratcliff, renowned landscape photographer and Lytro pro-shooter team member.

In addition to Perspective Shift, Lytro announced a new way to enhance light field pictures with Living Filters. With a single click, Lytro photographers will be able to apply one of nine interactive filters to their pictures and change the look of the picture based on light field depth. Unlike traditional digital photo filters, Living Filters create additional effects as viewers interact with a picture. Living Filters is a free update to Lytro Desktop and works on all Lytro light field pictures, including retroactively.

New Living Filters:
· Carnival: Twist and distort your picture as you refocus and change perspective as if you're in a funhouse of mirrors.

· Crayon: Add a touch of color to a monochrome version of your picture. Click to focus and add color into your scene, or change your perspective and add color back into your scene as you explore.

· Glass: Put a sheet of virtual glass into your scene. Everything in front of where you click will be unchanged, and everything behind will appear to be behind a piece of frosted glass.

· Line Art: Reduce your scene to a grayscale outline, seeing more detailed lines where you refocus.

· Mosaic: Create a tiled mosaic in the out-of-focus parts of your scene as you click or change your perspective.

· Blur+: Significantly enhance the amount of blur in the out-of-focus parts of your scene.

· Pop: Make parts of your scene pop out with extra detail and vibrancy when those areas are clicked.

· Film Noir: Add a moody and stylized black and white look to your pictures, with a little bit of extra detail and color where you click.

· 8-Track: Bring back the '70s with this filter that adds an aged, vignetted look to your pictures. Click to un-age parts of your scene and see them come back to life, disco suit not required.


"Having the ability to play with tiles of your living pictures while you refocus with Mosaic or to give an evening shot more drama with Film Noir will let Lytro camera owners and their friends and family have even more fun with the light field and the living pictures it creates," said Eric Cheng, director of photography at Lytro.
