Can anyboby can teach me what's hot pixels. & what's the different between hot pixels & dead pixels ?? & is it both must use software to check ? & what's the software for each or use same software?

"hot pixels are a fact of life.....A hot pixel can range from bright white to something just barely distinguishable from black.......But with exposures of a quarter second or less, hot pixels just shouldn't appear in your images. If they do, you've got a returnable product." Dead pixels is dead so it s dark. Always return if have dead pixels.

HOT PIXELS

One of the better know software for testing hot/dead pixels

pixel test

I mean ...it seems it s a bit oversimplifying the case if you said you must reutrn the product if you find hot pixels. You must find them depending on your settings. Hmm I m no photographer. Just a bookworm trying to share some readings.

用眼看見有一粒...當然換啦....你想想將來影出來張相有一點灰了, 你會接受嗎?

hmm.. I an trying to say. When you take your dark pic, there may be a chance that the camera is still in P mode, tehn teh exposure time may be in mutliples of seconds, in that case, it is not that reliable. Otherwise, of course you should change.
