comment How can I reduce the noise present when taking pictures without lowering my ISO?
That is incorrect, some cameras have some built in capability and they are getting better. I have also read a Microsoft Research paper from SIGGRAPH on how to enhance images using images from a video clip, including improving the lighting and reducing blur, either globally or locally (for only one object or the entire scene).

comment What can a fisheye lens be useful for?
Getting rid of the distortion when you have information regarding the lenses is more accurate.

+1 Beautiful examples, however the distortion is still noticeable. - The panoramic views do however greatly distract you from it.

+1 Increasing the exposure time is NOT the only other option, but it will work in some cases (see my answers/comments above) and you were the first to suggest it here.

@Dave I agree - there are many techniques, each with its advantage and disadvantage.

If the burst of images is fast enough and you weigh a motion detection algorithm in the averaging the results should be good. If you increase the exposure time then you basically doing the same thing, only the burst it continuous and automatically averaged and you have no way to tell if something moved and compensate.

Overexposing the picture will reduce the noise, but will also increase the motion blur (motion of camera and/or subject). Taking a burst of photos then detecting the motion and averaging them (minus the motion's effects) will give you the same affect, but hopefully minus the blur (if motion detection and reduction is good).

@Justin, yes the noise level is directly proportional to the temperature of the sensor.

Also, don't forget to add copyright info to the EXIF.

Here is an example of mine on how a watermark can be tasteful. As to the question of whether or not it helps, I agree with Reid. cgm.technion.ac.il/Computer-Graphics-Multimedia/…

comment How can I get a good HDR image from a single RAW file?
What is the dynamic range of your camera's sensor (how many bits per pixel)? Can you adjust the pixel format of the raw file?
