下一代 photoshop cs4 會有 64bit 加強版但 apple user可能無份, 我估係 apple 想推自己 software, 所以同 adobe 關系唔多好.

好多公司用 ps 都仲用緊 cs2, 幾時先到 cs4 =.=
用到先算啦

[yung2]

64bit 版係咪會快d?

我屋企用o既係ps7 =..="

公司用o既係cs1, 其實都無乜大改動而真係好有用的功能,

加d 3D或修相功能呢d都係好次要o既野,

軟件每改版一次, 運算速度就更慢, 搞到買新機都無幫助~

如果你影 jpeg 或者唔買新機, 新 version ps對你無乜影響.
但如果你影 RAW又買新機, 舊 version ps 通常會唔再 update RAW support.

哦, 變左好似我咁要係Canon個dpp改完色再係photoshop加logo改size.

Photoshop CS4 to be 64-bit for Windows, but not Macby Jim Dalrymple, Macworld.com
Apr 3, 2008 12:01 pm
Adobe’sflagship product, Photoshop, will become a 64-bit application in thenext major revision to the company’s bundle of creative proapplications, Creative Suite 4. However, the 64-bit version will onlybe available to Windows users because of a change Apple made at itsWorldwide Developers Conference (WWDC) in 2007.
The good news is that Adobe will make a 64-bit version for the Mac in the future.
“Wecan reassure people that literally from the day we found out Carbon64-bit was cancelled, we have been figuring out what we need to do toget there,” John Nack, senior product manager for Adobe Photoshop, toldMacworld.
At WWDC 2007Apple discontinued its Carbon 64-bit program, which left company’s likeAdobe without an avenue to make its current codebase 64-bit. What Adobehas to do now is transition all of the old Photoshop code to Apple’snative Cocoa programming language, where it can then be made 64-bit.
“If you want to go 64-bit on the Mac, you have to port to Cocoa and that’s not a trivial task,” said Nack.
Adobesaid that they have been working on the Carbon 64-bit version ofPhotoshop for some time and had planned on releasing a version forCreative Suite 4 (CS4). However, with the changes at WWDC 2007, that isnot going to happen.
“Our feeling has been to deliver 64-bit onboth platforms for this release,” said Nack. “We could hold back theWindows 64-bit version until we could catch up on the Mac, but thatdidn’t seem fair to those customers.”
If one good thing cancome out of the delay, Nack says Adobe will gain valuable experience inwriting 64-bit applications, albeit for Windows.
While Apple has been dabbling with 64-bit support in its hardware and software for the past several years, Mac OS X Leopard is the company’s first 64-bit operating system. The move to 64-bit applications will help those that are working with huge amounts of memory (over 4GB) the most.
However,if you are using files for the Web or other smaller tasks, “youprobably won’t see a huge speed bump,” said Nack. Adobe said you couldexpect an eight to 12 percent performance increase with the smallerfiles.
Just 24 hours ago, Adobe released its first Mac 64-bit application with the introduction of Photoshop Lightroom 2.0 beta.
Adobewouldn’t give a timeframe on the release of the 64-bit version ofPhotoshop or when we could expect CS4, but the company usually works onan 18-24 month cycle in major product releases. Creative Suite 3 wasreleased March 27, 2007.
“We work hard on platform parity andwe know it’s going to be disappointing for Mac users, but we don’t wantthat to overshadow all the other good things we have for this release,”said Nack.

何以分道揚鑣？

Adobe原本計畫要把64-bit CS4搬到Mac平台，直到2007年六月時蘋果在全球開發者大會上做了二項宣佈，Nack說。

蘋果有兩種協助開發人員採用其作業系統上的記憶體、字型或視窗管理的技術，分別是Carbon 及Cocoa。原本兩種技術都會包含在64-bit作業系統中，但在大會中，蘋果表示新作業系統中只會提供Cocoa。而Photoshop則是從Mac OS 9時代以Carbon寫成，而且比較適合跨平台開發。Cocoa和Mac OS X一樣，是來自Steve Jobs前公司Nextstep。

「他們既然選擇不再推出Carbon 64，那我們也得重新評估未來的路，」Nack說。該公司立即要求新的開發人員使用Cocoa「以便能儘快轉移過去，但俗話說，生孩子也要九個月，不可能一夜之間改變。」

用到Carbon功能的程式碼為數相當多：大約一百萬行，而且全部都得重新檢視，Nack說。即使到了今天，「我們都還不知有多少得重寫或修改。」

Carbon轉換到Cocoa工程浩大，CS4要改幾個月不可能來得及，他補充。

「沒有人，不論是蘋果、微軟或Adobe，願意把像Photoshop那麼大的應用程式從Carbon轉換到Cocoa上。」Nack說。
