Hot pixels

[paleblue]

Last night I was experimenting with star trails through my bedroom window. Achieved what I wanted and kept one of the 30 sec files to overlay for the interior (all the editing for the stars blacked out the room). My camera is a year old, and already looks plagued by hot pixels.

Is this the beginning of the end for my sensor?? or just one of the cons of digital photography that most people suffer with?

This is the highest concentration, there are a few more in different areas of the frame. This is a 100% crop, and the file size was set to small (minimize iso noise)

:shrug:

Part of the experience of digital, when exposing for long periods of time some sensor sites get a bit funny and do that. Turn on Long Exposure Noise Reduction and it will remove that.

Sensor shouldn't die, mine has done that for nigh on 4 years and it's not dead yet.

You're lucky, try that with a Nikon D80 or D200 and you'd have a whole galaxy of those

The long exposure noise reduction uses dark frame subtraction to remove the hot pixels, this doubles the exposure time. Wikiexplaination

and the Fuji S5 , looks like the milky way if you take a shot with the lens cap on

Either your sensor's croaked or the battery's flat :shrug:

screen is completely black nothing at all if anyone wants a jpeg as I must be doing something wrong pm me with email addy and I will send it to you probably you may find some but I cant

 

[Dangermouse]

do I have to blow the photo up or anything

I had to bite and try this also, but didn't notice one hot pixel at all. Is it really a common problem? Genuine question as I'm curious even though it would seem easy enough to remove hot pixels with a quick cloning.

Just tried at f22 with 30sec shutter speed, still none, am I doing something wrong or just lucky?
