I was testing my camera, a little obsessed. I notice something that look like hot pixels, something like a red / green / blue spot that always appear in the same spot.. Noticed few of them repeating in most of the pix taken with poor lighting condition.. So I did a dark frame test, cover the lens and snap a pix in the dark room. Thankfully no hot pixel show up, even if the JPEG compression is high, if there is a hot pixel it would definitely show up.. So I conclude that the JPEG compression done on the photos taken is damn damn high.. Cause for a 8mp sensor pix with size range of 1mb to 2mb is consider quite low.. Meaning lots of compression is done to reduce the file size... That is why pix taken with low light condition is terrible!!! Sometimes there is even slightly visible lines.. blame the software for this...
Those who are interested can google hot pixel detector. Most of them is usually freeware but since the pix taken with N86 is compressed kao kao so no point testing also but if you got other camera and didn't know, can give it a try..
wow.. is that the hot pixel usually noticable when taking in the dark rite? is there any way to minimixe compression? or that the limt for our cam? hmmThose who are interested can google hot pixel detector.
