我用 D40 唔覺咁慢喎, 我用買機送既 cheap card. 即管借另外一張 SD card 試下囉. 一係 menu 度較細 d file size 睇下有無分別.

我用jpeg fine呀................有用noise reduction

[lym3]

我都唔用 NR.

下面係 copy from Kenrockwell site.


Noise Reduction

This is short for Long Exposure Dark-Frame Subtraction Noise Reduction.

It doesn't reduce noise or grain. It will eliminate the occasional hot pixel, and correct purple fog around the edges of insanely long astronomical exposures.

OFF: Default. Leave it here.

ON: Don't use this. If you do, the D40 will double the amount of time you have to wait around for time exposures of a second or longer. You people who need this know who you are, and even for you I suggest trying the D40 with out NR first. it may save you a lot of time waiting around out in the cold.
