請問係咪影幾張全黑相, 用1/5, 1/10,1/15,1/30快門, 跟住用dead/hot
pixel test 測試. 但係"threshold for hot /dead pixels "一欄中輸入什麼
數值,請指教.

就咁test 囉

They suggest 60 and 250 law.

快門最好set慢d，2、4、8秒影幾張試，記得要用tiff非壓縮檔案格式﹗
除?影全黑，亦要影張全白，然後係mon到以100%放大率用自己對眼檢查。^_^

請問點樣由jpeg 格式轉去tiff 格式.......謝謝

[Velsper]

JPG也沒問題的
jpg比tiff的失真影響不大


由jpeg轉tiff的意義不大因相片在jpeg時已經有"損失"了
koala bear所說的是用super fine mode去影
那相機就會用tiff(非破壞格式)去存了

ps 小弟會放大到400%~

唔係用轉0既，係0向你部機揀最高格式( HI )，出0黎就會係 tiff 0架..

try click on and read ths on DEAD PIXELS
In your camera Shooting Menu, you can shoot output as TIFF file for some models. If your DC doesn't have that choice, just choose the best (highest pixel, very fine resolution) Jpeg.

用400%檢查，小弟恐怕會眼花了﹗@@"
佩服﹗

[Pooh Pooh]

4秒影黑相開始有hot pixel 有冇問題0架？

[tsinhm]

明白, 即係用raw 影黑白相, 謝謝各位.

我發覺影全白相時, 左右下角都有D暗位, 點算?
