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

=====
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.

interviewer tip


The best way I've found to interview candidate developers is to pair program with them to do real work on the actual code of the project that is hiring. If not possible, give programming exercise which is:

The exercise must involve working with current development tools.
The exercise must require the candidate to apply important features of the language.
The exercise must involve understanding and working with existing code.
The exercise must involve error handling.
The exercise must involve testing.
The exercise must offer scope for domain modelling.
The exercise must involve asking questions.
The exercise must be realistic.
The exercise must involve changing requirements.
The exercise must offer the candidate enough rope to hang themselves.
The exercise must test many different skills and practices.

A good interview programming exercise takes at least an hour. - http://nat.truemesh.com/archives/000630.html

meeting


Tips for getting the most from meeting - http://cn.wsj.com/big5/20120224/eoe082439.asp?source=rss

No meeting should ever be more than an hour, under penalty of death.
Every meeting should have a clearly defined mission statement.
Do your homework before the meeting.
Make it optional.
Summarize to-dos at the end of the meeting.

Getting rid of util class
1) If the family of methods uses different parameters, depending on optional input or representations of the same input, then consider transforming the Helper via a fluent interface using the Builder pattern: from a collection of static methods like Helper.calculate(x), calculate(x, y), calculate(x, z), calculate(y, z) we could easily get to something like newBuilder().with(x).with(y).calculate(). The helper class would then offer behaviours, reduce its list of business methods and provide more flexibility for future extensions. Callers would then use it as internal field for reuse or instantiate it where needed. The helper class (as we knew it) disappeared.
2) If the helper class provides methods which are actually actions for different inputs (but, at this point, for the same domain), consider applying the Command pattern: the caller will actually create the required command (which will handle the necessary input and offer a behaviour) and an invoker will execute it within a certain context. You may get a command implementation for each static method and your code would move from an Helper.calculate(x, y), calculate(z) to something like invoker.calculate(new Action(x, y)). Bye bye helper class.
3) If the helper class provides methods for the same input but different logics, consider applying the Strategy pattern: each static method may easily become a strategy implementation, vanishing the need of its original helper class (replaced by a context component then).
4) If the given set of static methods concerns a certain class hierarchy or a defined collection of components, then consider applying the Visitor pattern: you may get several visitor implementations providing different visit methods which would probably replace partially or entirely the previously existing static methods.
5) If none of the above cases met your criteria, then apply the three most important indicators: your experience, your competences in the given project and common sense.
