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.

TDD


If you write the test after you've written the code, it's much more likely that you'll write the tests that will pass what you've written.

That's just how our brains work.

If you determine the criteria for whether a decision is good after you've already made the decision, it's much more likely that you'll create criteria that justifies the decision that was just made.

That's just how our brains work.

Determine how to assess whether something is good before you implement it and/or before you make a decision. Otherwise, you will tend to be emotionally attached to what you just did, what you just decided.

Does this mean I think you should skip TDD for programs you’re going to run once and then throw them away?

Well, I’m closer to OK with that than I am to the other cases here, but I often spend enough time editing and rerunning to make me think there was probably a central bit of the program that would have benefited from some TDD.

pair programming


https://martinfowler.com/articles/on-pair-programming.html

How work alone might be better than pairing - http://techcrunch.com[..]/03/pair-programming-considered-harmful/

When to pair, when not to - http://www.markhneedham.com[..]ramming-the-disadvantages-of-100-pairing

This is an excellent arguement -

It's only worth pairing on complex code, rote code yields no advantage.

I think there is a point to this - pairing is about improving design and minimizing mistakes. Rote code that's simple to write yields little opportunities for pairing to make a difference.

Except this: writing boring rote code is a smell. If I'm writing boring repetitive code it's usually a sign that I've missed an important abstraction, one that will drastically reduce the amount of rote code to write. Pairing will help you find that abstraction.
