Rarely will I get through every section of every book.  The idea is to create a kind of dialogue among the authors, identifying points of overlap and difference.  Very often, the ideas from one book will trigger ideas that have you scouring the other books for elaboration.  The mixture of ideas from several books will lead to a thought that is not contained in any of the books.  When you read in parallel, it's like being in the room while the authors are conversing.  The intersecting of ideas almost always stimulates fresh ways of thinking about (and applying) the topic at hand. - http://traderfeed.blogspot.hk[..]ding-in-parallel-becoming-better-at.html

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??

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.
