hot pixels Anonymous
sup /p/

here's a shot with the cap closed.
as you can see, there are several red and blue pixels.
so is this amount normal for this class of camera? as you can see, its an iso400 and 30seconds shot.
and why are they "areas" instead of just one pixel? is it a product of noise reduction?

sensor heat, hot pixels

Because a single cell on the sensor does not equal one pixel.

but that would mean that my cam only has like 2MP (judging from the size of the red/blue pixels)

plus:

You probably don't shoot good enough photos where those hot pixels would matter. And if you did, you didn't care about dead pixels..

If you're really going mental because of these, shoot raw and develop the photos with Adobe Camera Raw or similar program, which removes hot pixels.

Bayer sensor causes 1 pixel to look like many!

also buying a real camera will reduce hot pixels.

The number of defect pixels does not scale inversly with the price of a sensor. Sonys Exview HAD CCD sensors for instance have a really nice sensitivity and alone cost more than some complete cameras, but usually have more defect pixels than a 3$ cell phone camera. Your pixels are not really "hot", more like a little warmer than the rest, so they didn't get mapped as defect in the factory.
Also, see the bright patch in the upper right corner? That's the readout stage of the sensor. It is slightly warmer than the rest thus causing more dark current. You can use photos like this to subtract the dark offset for long exposure images.

Yes, this is normal.

>>2. Post only photos that show at least trace amounts of thoughtful composition. Do not upload random snapshots.

Take your techie problems somewhere else, idiot. This is a board about photographs, not about you needing to clean your fucking sensor.
