從 SLR 走到 DSLR

對攝影的興趣,早在八十年代經已產生。當年用了第一份工的第一個月的一整份工資,購買了第一部入門單鏡反光相機:Nikon FG 連一支 Nikkor 50mm f/1.4 標準鏡 (當時可算是 Kit Set),開展了我攝影/敗家的第一頁。

第二個月當然是繼續行敗,買了一支當時相對廉宜的 Series E Zoom Lens,Nikon Series E 70-210mm f/4.0。其間購買的配件也不用多說了。

此部 FG 機身用了約一年後,在 Nikon FA 推出時便賣掉了,補錢昇級了一部全黑版。當年我就是拿著一機兩鏡一支燈走遍大小比賽及宴會。而當時所有有限的攝影知識也是來自每月出版的相機世界、攝影雜誌等等,當然還有公共圖書館的攝影書籍。

此部 FA 跟了我好像有六七年,因工作及會務繁忙,便給荒廢了。之後更讓了給經常跟我借用的好友。最後只餘下兩支鏡頭,一直放在沒有更換防潮珠的防潮箱內,眨眼便已放了十年。

由於數碼相機的興起,所以一直使用輕便的 DC,直至此一日:Alvin 迪士尼四歲生日。

Canon Powershot G9 算是一部我非常滿意的 Prosumer 機,但就在上述第一次遊迪士尼時令我當頭捧喝。多年來我一直以為我已對相機沒太大要求,拍到相片便已足夠,但原來我的一團火仍未熄滅,當下立心要重返單反行列,從 SLR 走到 DSLR,將兩支手動鏡重見天日。

做了約半年的資料搜集,終於鎖定目標,入手剛推出半年的中高階全片幅數碼單鏡反光機 Nikon D700。

同時入手大三元中的 AF-S NIKKOR 24-70mm f/2.8G ED

考慮 FX 機的主要原因是考慮到仍放在防潮箱內的兩支寶貝,因為將它們放到 DX 機,會是一種浪費,亦未必可配合使用,而且,FX 機會是未來的大方向,不會在短期內被淘汰。

由於兩支舊鏡已放在全無防潮功能的箱防潮箱內這麼多年,可以想像到鏡頭會發霉到什麼程度!可是,直至最近,才有時間分別將兩支鏡修抺完成。

終於重見天日,一家團聚。

抺完鏡,當然是要試試它的效果。先來 Nikkor 50mm f/1.4,操作起來很順手,很有久別重逢的感覺。





再來 Nikon Series E 70-210mm f/4.0 迪士尼實戰 (更多當天的相片在此)。手到拿來,非常滿意及滿足!
(以下相片並不是全用 200mm 焦距拍的,只是相機內鏡頭資料只可選擇手動變焦鏡的單一數值,所以只選了 200mm 這數值)



數碼相片最方便是可以自行修正相片瑕疵,但也是最煩的一個步驟。經多月學習,現總算有點認識,懂得使用 Aperture 2 來作後期相片修正。無意中發現,用 42 吋 Plasma 來做 2nd Display 來修相也很有趣!哈!請不要認真呵!

Guinness

我對啤酒一直都興趣不大,主因容易上腦,產生不舒服感覺,通常一杯就已到位。但奇怪是,對於酒精濃度高的飲品則是例外。

啤酒中,Guinness (黑啤) 一直是相對較接受的啤酒,在於其獨有的苦澀味。以前飲黑啤最多的地方,要算是 AMS 的 Mess Club,但駱 Sir 離任之後就好像只飲過一次,直至近日。

早幾天,跟 Twit 友 「犯罪」時心血來潮叫了兩 round 黑啤,感覺良好


是夜再來自對一 round

藍牙立體聲耳機

藍牙耳機一直也有使用,數年前曾在這裡提及。至今仍經常使用的,就只有 Plantronics Discovery 665,但它被長置於車上,只限於駕駛時跟 Centro 配搭使用。

自前年加入 iPhone 行列後,身邊便經常多袋一條耳機線來聽 Podcast 及音樂。用得最多的,要算這隻由 @macjuju 介紹的 Sennheiser CX400 了!

CX400 主線只長六十多厘米,而且是入耳式,相比起 iPhone 的原裝線,方便得來聲又靚,價格亦相宜。

由於近月使用了KKBOX 的服務,除了使用 iPhone 來聽音樂外,使用 MBA 也多了。忽發奇想,既然 iPhone 跟 MBA 也有藍牙裝置,何不使用一只藍牙耳機來滿足兩部裝置的使用呢?!

藍牙立體聲耳機市面上也有不少選擇,但外型一直未有一部看得上眼。月前無意中發現 Sony Ericsson 一款 HBH-IS800 的藍牙耳機,外型極度吸引,更只有 12 克,只不過由於 iPhone 不支援 AVRCP,聽音樂時不能調教大細聲,因此一直在觀望。

直至上月中,發現跟 Sony Ericsson Xperia™ X10 同期推出的 MW600 很是吸引,何以吸引呢?就是它的獨立收音機功能、使用 Micro USB 叉電及可連接三部裝置的能力,而且,還可用回我自已的 CX400 立體聲耳機。

由於是新機關係,基本上各大電器連所店仍未有貨。終於今天在星際找到,比起行貨訂價平了一佰。

我總共 pair 了三部裝置,包括 iPhone,Centro 及 MBA。經初部試用,聽歌及收音機部份不錯,但電話收音似乎有點問題,跟好友測試時,對方聽到我的說話有點斷續,待明天在戶外再行試清楚一點。

當連接到 iPhone 時,會自動顯示當時時間,但當連到 Centro 時,時間則會顯示為 0:00!

另外發現,當 MW600 正處於電話待機狀態時,是可以將它連到 MBA 來聽音樂,當然也可以轉至收音機模式。當有來電時,它會自動轉駁電話,而當收線後,又會自動駁回 MBA。可惜電腦的音樂並不會像電話般會自動暫停呢!

跟機來的 in-ear 線其實也是不錯,只是未煲夠火,一於是晚將它煲個通宵,加速它的火喉!

Apple 教主的聖旨

Apple 教主 Steve Jobs 今天發表了一編關於 Adobe Flash 的文章,狂打 Flash,我相信明天將有好戲睇了!

Thoughts on Flash

Apple has a long relationship with Adobe. In fact, we met Adobe’s founders when they were in their proverbial garage. Apple was their first big customer, adopting their Postscript language for our new Laserwriter printer. Apple invested in Adobe and owned around 20% of the company for many years. The two companies worked closely together to pioneer desktop publishing and there were many good times. Since that golden era, the companies have grown apart. Apple went through its near death experience, and Adobe was drawn to the corporate market with their Acrobat products. Today the two companies still work together to serve their joint creative customers – Mac users buy around half of Adobe’s Creative Suite products – but beyond that there are few joint interests.

I wanted to jot down some of our thoughts on Adobe’s Flash products so that customers and critics may better understand why we do not allow Flash on iPhones, iPods and iPads. Adobe has characterized our decision as being primarily business driven – they say we want to protect our App Store – but in reality it is based on technology issues. Adobe claims that we are a closed system, and that Flash is open, but in fact the opposite is true. Let me explain.

First, there’s “Open”.

Adobe’s Flash products are 100% proprietary. They are only available from Adobe, and Adobe has sole authority as to their future enhancement, pricing, etc. While Adobe’s Flash products are widely available, this does not mean they are open, since they are controlled entirely by Adobe and available only from Adobe. By almost any definition, Flash is a closed system.

Apple has many proprietary products too. Though the operating system for the iPhone, iPod and iPad is proprietary, we strongly believe that all standards pertaining to the web should be open. Rather than use Flash, Apple has adopted HTML5, CSS and JavaScript – all open standards. Apple’s mobile devices all ship with high performance, low power implementations of these open standards. HTML5, the new web standard that has been adopted by Apple, Google and many others, lets web developers create advanced graphics, typography, animations and transitions without relying on third party browser plug-ins (like Flash). HTML5 is completely open and controlled by a standards committee, of which Apple is a member.

Apple even creates open standards for the web. For example, Apple began with a small open source project and created WebKit, a complete open-source HTML5 rendering engine that is the heart of the Safari web browser used in all our products. WebKit has been widely adopted. Google uses it for Android’s browser, Palm uses it, Nokia uses it, and RIM (Blackberry) has announced they will use it too. Almost every smartphone web browser other than Microsoft’s uses WebKit. By making its WebKit technology open, Apple has set the standard for mobile web browsers.

Second, there’s the “full web”.

Adobe has repeatedly said that Apple mobile devices cannot access “the full web” because 75% of video on the web is in Flash. What they don’t say is that almost all this video is also available in a more modern format, H.264, and viewable on iPhones, iPods and iPads. YouTube, with an estimated 40% of the web’s video, shines in an app bundled on all Apple mobile devices, with the iPad offering perhaps the best YouTube discovery and viewing experience ever. Add to this video from Vimeo, Netflix, Facebook, ABC, CBS, CNN, MSNBC, Fox News, ESPN, NPR, Time, The New York Times, The Wall Street Journal, Sports Illustrated, People, National Geographic, and many, many others. iPhone, iPod and iPad users aren’t missing much video.

Another Adobe claim is that Apple devices cannot play Flash games. This is true. Fortunately, there are over 50,000 games and entertainment titles on the App Store, and many of them are free. There are more games and entertainment titles available for iPhone, iPod and iPad than for any other platform in the world.

Third, there’s reliability, security and performance.

Symantec recently highlighted Flash for having one of the worst security records in 2009. We also know first hand that Flash is the number one reason Macs crash. We have been working with Adobe to fix these problems, but they have persisted for several years now. We don’t want to reduce the reliability and security of our iPhones, iPods and iPads by adding Flash.

In addition, Flash has not performed well on mobile devices. We have routinely asked Adobe to show us Flash performing well on a mobile device, any mobile device, for a few years now. We have never seen it. Adobe publicly said that Flash would ship on a smartphone in early 2009, then the second half of 2009, then the first half of 2010, and now they say the second half of 2010. We think it will eventually ship, but we’re glad we didn’t hold our breath. Who knows how it will perform?

Fourth, there’s battery life.

To achieve long battery life when playing video, mobile devices must decode the video in hardware; decoding it in software uses too much power. Many of the chips used in modern mobile devices contain a decoder called H.264 – an industry standard that is used in every Blu-ray DVD player and has been adopted by Apple, Google (YouTube), Vimeo, Netflix and many other companies.

Although Flash has recently added support for H.264, the video on almost all Flash websites currently requires an older generation decoder that is not implemented in mobile chips and must be run in software. The difference is striking: on an iPhone, for example, H.264 videos play for up to 10 hours, while videos decoded in software play for less than 5 hours before the battery is fully drained.

When websites re-encode their videos using H.264, they can offer them without using Flash at all. They play perfectly in browsers like Apple’s Safari and Google’s Chrome without any plugins whatsoever, and look great on iPhones, iPods and iPads.

Fifth, there’s Touch.

Flash was designed for PCs using mice, not for touch screens using fingers. For example, many Flash websites rely on “rollovers”, which pop up menus or other elements when the mouse arrow hovers over a specific spot. Apple’s revolutionary multi-touch interface doesn’t use a mouse, and there is no concept of a rollover. Most Flash websites will need to be rewritten to support touch-based devices. If developers need to rewrite their Flash websites, why not use modern technologies like HTML5, CSS and JavaScript?

Even if iPhones, iPods and iPads ran Flash, it would not solve the problem that most Flash websites need to be rewritten to support touch-based devices.

Sixth, the most important reason.

Besides the fact that Flash is closed and proprietary, has major technical drawbacks, and doesn’t support touch based devices, there is an even more important reason we do not allow Flash on iPhones, iPods and iPads. We have discussed the downsides of using Flash to play video and interactive content from websites, but Adobe also wants developers to adopt Flash to create apps that run on our mobile devices.

We know from painful experience that letting a third party layer of software come between the platform and the developer ultimately results in sub-standard apps and hinders the enhancement and progress of the platform. If developers grow dependent on third party development libraries and tools, they can only take advantage of platform enhancements if and when the third party chooses to adopt the new features. We cannot be at the mercy of a third party deciding if and when they will make our enhancements available to our developers.

This becomes even worse if the third party is supplying a cross platform development tool. The third party may not adopt enhancements from one platform unless they are available on all of their supported platforms. Hence developers only have access to the lowest common denominator set of features. Again, we cannot accept an outcome where developers are blocked from using our innovations and enhancements because they are not available on our competitor’s platforms.

Flash is a cross platform development tool. It is not Adobe’s goal to help developers write the best iPhone, iPod and iPad apps. It is their goal to help developers write cross platform apps. And Adobe has been painfully slow to adopt enhancements to Apple’s platforms. For example, although Mac OS X has been shipping for almost 10 years now, Adobe just adopted it fully (Cocoa) two weeks ago when they shipped CS5. Adobe was the last major third party developer to fully adopt Mac OS X.

Our motivation is simple – we want to provide the most advanced and innovative platform to our developers, and we want them to stand directly on the shoulders of this platform and create the best apps the world has ever seen. We want to continually enhance the platform so developers can create even more amazing, powerful, fun and useful applications. Everyone wins – we sell more devices because we have the best apps, developers reach a wider and wider audience and customer base, and users are continually delighted by the best and broadest selection of apps on any platform.

Conclusions.

Flash was created during the PC era – for PCs and mice. Flash is a successful business for Adobe, and we can understand why they want to push it beyond PCs. But the mobile era is about low power devices, touch interfaces and open web standards – all areas where Flash falls short.

The avalanche of media outlets offering their content for Apple’s mobile devices demonstrates that Flash is no longer necessary to watch video or consume any kind of web content. And the 200,000 apps on Apple’s App Store proves that Flash isn’t necessary for tens of thousands of developers to create graphically rich applications, including games.

New open standards created in the mobile era, such as HTML5, will win on mobile devices (and PCs too). Perhaps Adobe should focus more on creating great HTML5 tools for the future, and less on criticizing Apple for leaving the past behind.

Steve Jobs
April, 2010

Adobe CEO Shantanu Narayen 及後在 The Wall Street Journal Live Blog 的回應!

Alan Murray begins the interview, calling Mr. Jobs's missive an "extraordinary attack." He asks Mr. Narayen what Adobe has done to deserve this.

Mr. Narayen says that the difference is that Adobe believes in open content. He says that their Creative Suite software was designed to work on multiple devices and that Apple's "recent behavior shows that they are concerned about Adobe being able" to provide this product that works across multiple platforms.

Mr. Murray likens the Apple-Adobe fight to that between reality TV stars Jon and Kate Gosselin and asks about the history between the two companies. Mr. Narayen says that Adobe has been "true to the position" with which it was founded and to the idea that it should help people deal with multiple operating systems.

Mr. Narayen talks about Adobe "certainly" shipping on Android's latest version. He says that it is an "incredibly productive time" for Adobe and discusses Creative Suite 5, saying that Adobe's "innovation is blowing people away."

The technology problems that Mr. Jobs mentions in his essay are "really a smokescreen," Mr. Narayen says. He says more than 100 applications that used Adobe's software were accepted in the App Store. "When you resort to licensing language" to restrict this sort of development, he says, it has "nothing to do with technology."

He says that Apple's restrictiveness is just going to make it "cumbersome" for developers who are trying to make products that work on many devices. They're going to have to have "two workflows" ... one for Apple devices and one for others.

Speaking about Mr. Jobs's assertion that Adobe is the No. 1 cause of Mac crashes, Mr. Narayen says if Adobe crashes Apple, that actually has something "to do with the Apple operating system."

Mr. Narayen calls accusations about Flash draining battery power "patently false." Speaking about Mr. Jobs's letter in general, he says that "for every one of these accusations made there is proprietary lock-in" that prevents Adobe from innovating.

Mr. Narayen poses a question to Alan Murray, asking him if the Journal would "want to have stovepipes" -- or separate development processes -- when it is creating content. Mr. Murray says that certainly "it would be better if you could use one set" of development tools.

Mr. Narayen says Adobe's concept is best for most businesses that are developing applications and allows them to send their apps out to many places rather than forcing them to decide on just one. "It doesn't benefit Apple, and that's why you see this reaction," he says.

Responding to a question about Mr. Jobs's assertion that Adobe is a closed platform, Mr. Narayen chuckles. "I find it amusing, honestly. Flash is an open specification," he says.

The Journal wants to know whether Mr. Narayen knows Steve Jobs. "I've met him on a number of occasions," he says.

"We have different views of the world," Mr. Narayen says. "Our view of the world is multi-platform."

Does Mr. Narayen use an iPhone? "I have a Google Nexus One device," he says. And what about the iPad? "I think it's a good first-generation device. I think you're going to see just tremendous innovation in terms of tablets." Adobe is, in fact, working with "dozens" of tablet projects with other companies, he says.

To conclude, Mr. Narayen says he's for "letting customers decide," but that the multi-platform world will "eventually prevail." And the interview wraps up.
