星軌拍攝技巧 數問 - 1).數碼機因hot pixel而唔適合曝得耐...最好分開影影夠幾個鐘...咁每張間隔之間都要俾CMOS斗下氣？ 有師兄 教過 分十幾張 每張 10-20min 再合成 好過 一野 暴 幾粒鐘, (菲林 令計) 2).數碼機有D人話用ISO 100、有人話用ISO 400-800好...如果用合成方法...其實係咪都係就番光害而定...定係關雜訊事？ 睇天氣 , 小弟 用 o個次 用 iso 100 5).北極星仰角澳門係23度，咁香港一樣？？ 4季 都唔同 位置, 用星座 搵 會準確 d, e+ 係 冬季, 北極星 位置 係 獵戶座 (lei 個最易 認, 唔會 搵唔倒 ... ) 頭頂 (腰帶 致 頭頂 距離 再過 5倍左右) 附圖 係 舊年 去雲南 香格里拉 時影, 本泥想 長暴, 不過 o個晚 太涷 個人 頂唔順 要收皮 反酒店 http://www.dchome.net/viewthread.php?tid=798154 With a lot of information, 香港的星空 — 觀測及拍攝資訊 - http://www.dcfever.com/column/read.php?id=1829 Herman's articles at dcfever - http://www.dcfever.com/column/info.php?id=185 500px tutorial - http://500px.com/blog/738/tutorial-photograph-the-night-sky About Comet - http://www.dcfever.com/column/read.php?id=2193 Atmospheric optical phenomena 大氣光學現象 - http://matthew-chin.blogspot.hk[..]16/06/atmospheric-optical-phenomena.html Stars & Night Sky - http://www.mikkolagerstedt.com[..]top-5-tips-to-photograph-stars-night-sky ===== 這張是11月15日凌晨拍攝的M42獵戶座星雲, 大埔的光害較嚴重, 所以要加上IDAS V4濾鏡作長時間曝光, 分三段不同時間曝光及作Layer Masking 處理, 把動態範圍拉闊. 在月光的影下算是滿意, 希望之後可以分數晚作10小時以上的曝光並加長每一張frame 的曝光時間 (現在是5分鐘一張), 使到暗位的表現進一步改善.

Linus share about project management, most importance is people, and also discuss about tools, how to collabrate people and how to delegate - http://h30565.www3.hp.com[..]Software-Development-Management/ba-p/440 Only the programmer who is going to write the code can schedule it. Any system where management writes a schedule and hands it off to programmers is doomed to fail. Only the programmer who is going to do the work can figure out what steps they will need to take to implement that feature. - http://www.joelonsoftware.com/articles/fog0000000245.html Never, ever let managers tell programmers to reduce an estimate. Many rookie software managers think that they can "motivate" their programmers to work faster by giving them nice, "tight" (unrealistically short) schedules. I think this kind of motivation is brain-dead. - http://www.joelonsoftware.com/articles/fog0000000245.html Micromanagement or Macromanagement? http://boncey.org/2006_10_29_how_to_mentor_programmers But, unfortunately, as a general rule, Project Managers have no training. Even if they do have training in the form of an MBA, MBA education is impractical and useless; the academic community has completely failed us in this respect. Furthermore, Project Managers are more often based on personal friendships and company politics; they are rarely based on management skill. And, finally, most managers do not acknowledge that management is a skill that they must study and learn so they don't study or learn it. http://discuss.joelonsoftware.com[..]DiscussTopicParent=8469&ixDiscussGroup=5 An explanation of agile, I think it is more about project management - http://blog.objectmentor.com/articles/2007/04/23/short-reach Some common problem of software project management - http://ajaxwidgets.com[..]thomas/9_reasons_why_software_project.bb http://ntschutta.com[..]ou-know-your-project-is-in-trouble-when/ http://www.goodproductmanager.com[..]roduct-management-vs-project-management/ Brief description of thoughtworks codejam - http://blog.nona.name/200804274.html Listen first.
