再來一個聯想話題
醫學上有個詞「遲發性」 上面雖然說計畫性 規律生活下 不易產生毒癮 但 會不會有遲發性後遺症? 就像食用黑心食品 有很大部分的人不會說馬上反應生理病徵 但累積到臨界點時 就突發性表象 不是不可能的 能代謝就沒問題不能就累積;看不到而不自知 所以啦 有人提醒是個福 現今的人拜網路資訊能無所不知 (先別論是否過濾) 也因此過於自信 (消化不良的自信常會讓人後悔) 使年長者的經驗變的不是這麼受用 產生出嚴重的代溝與理念差距 雖然以前就是如此 但資訊爆量消化不良 使年齡級距變的更小 以上東講講西說說 覺得扯遠、負面、無深度勿怪 結論只是想說 沒錯啦 看開點 看不開就起身走走打個盹 一切就又有另一片天可發揮 (無針對性 純為激發性聯想文) |

Solutions for Photographing in Cold Weather
http://www.bhphotovideo.com/explora/...g-cold-weather How the Cold Affects Your Camera （寒冷如何影響您的相機？此段短文中，敘述了關於低溫對電子式相機的影響） Just as any other battery-reliant electronic device suffers in the cold, cameras, and especially their batteries, perform at less than full capacity in low temperatures. Batteries suffer in the cold due to the fact that the chemical reaction that occurs in order to provide power is slowed down in colder temperatures. This affects the overall output, because they will lose capacity more quickly due to the fact they are not able to facilitate the production of energy, once their process has been slowed down too much. The best way to work within this constraint is to carry backup batteries in an inside coat pocket while shooting in the cold. By having fresh, warm batteries available you will be able to quickly switch batteries as they lose power at a faster rate, due to the low temperature. Once a depleted battery is brought back to room temperature, it should function regularly again. |
