Go to last post
... and only kicks in for long exposures (not sure of the exact value but I think it is 1sec and above).

I haven't done a lot of night shots, but there does seem to be too many stars in that night sky. Are you sure that last shot was 16 sec? I can't believe the people in it would have been still for 16 sec and that nothing in the picture showes any sign of movement. Am I missing something?

Excerpt from Todd Tieman, Oly Amer, on dealing with noise after the fact:

"Noise is an issue with all digital cameras. The noise pretty much lives in the blue channel. You can use photoshop and go into the blue channel and run a despeckle then convert to CMYK and sharpen the black channel."
 
For Johny Ko:

Some of those speckles refered to as "stars" by some on here, actually seem to be dead pixels.......In two of the pics, 2 dots appear in exactly the same place, despite the scene in the second being completly different from the first.

I would use your pixel mapping feature to eliminate these before you try taking more test pics.

If you get "stuck", "bad", or "dead" pixels you should run pixel mapping.

I have the C-730 and a couple of days ago I discovered at least one dead pixel. I had never used pixel mapping so I thought I would try it.......It worked!

If your C-750 has the same menu setup as the C-730, you should find it by setting the camera to A/S/M then press the "OK" button then "mode menu" to bring up the menu index.

Scroll down to "set" (setup) then press the right arrow then scroll down to "pixel mapping", again press the right arrow and it should say "start".

Press the "OK" button and wait until its finished. It should only take a few seconds, then press the "OK" button to exit the menu's and try taking a few test pics.

The dots should now be gone!

This does not damage the camera in any way and you can do this as many times as you need, should anymore dots, or "dead pixels" appear in the future.

In the very unlikely event it does not work then yes, you should return your camera and swap for another.
