These 3 Hacks Will Make You Remember More - https://betterhumans.coach.me[..]will-make-you-remember-more-b30a3d9b3136 When trying to memorise new material, it’s easy to assume that the more work you put in, the better you will perform. Yet taking the occasional down time – to do literally nothing – may be exactly what you need. Just dim the lights, sit back, and enjoy 10-15 minutes of quiet contemplation, and you’ll find that your memory of the facts you have just learnt is far better than if you had attempted to use that moment more productively. - http://www.bbc.com[..]effortless-way-to-strengthen-your-memory This one is funny: "Distract yourself. You might feel like you’re being super productive and focused by sticking to your work, but you’re less likely to recall it later." - https://medium.com[..]-and-it-can-actually-be-fun-99a9c9b95d5b https://list25.com[..]proof-techniques-to-enhance-your-memory/ http://www.bbc.com[..]-make-you-smarter?ocid=global_future_rss Drawing something makes it easier to remember than writing it down - https://www.zmescience.com[..]drawing-better-than-writting-memory-0432 http://www.bbc.com[..]s-your-memory-is-stranger-than-you-think

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.
