Q. I want to get an EXCELLENT camera for video taking. I love the Samsung camera features and everything, but the Nokia Lumia 920 has great quality too. I would prefer the Samsung camera but Im not sure... PLEASE HELP.
Thanks. :)
Thanks. :)
A. They did a recent test of those in What Digital Camera Magazine here:

They reckon the Samsung is the better phone cam.
The new Lumia 1020 will be rather similar to the quality of the old 808.... as good as a cheap compact but a hundred times more useful because you will always have your phone camera with you. As a result it's futile to try to talk down this fast evolving sensor technology

James Webb Space Telescope better than Hubble?
Q. Just curious if you have heard about this telescope that is supposed to be launched in 2013.
Here's the link:

Also, I'm trying to recall a certain imaging technique that combines x-ray images, infrared images and I believe UV images. After taking multiple images of space with those different cameras, they align them on top of each other to create astounding images.

A. Certainly will be far more superior than hubble which is great because hubble has seen billions of years into the past at high resolution. They've picked out regions of space wider than tennis ball or base ball and have generated stunning images of many galaxies and nebulal. So the JWST will be superior in that Hubble is over 20 years old, physically and in design. Even with upgrades [to Hubble], a new telescope will blow Hubble out of the water. I just hope they don't have to launch a rescue missin because something "was off."
As for the imaging they used for the Hubble Deep Field and Hubble Ultra Deep Field images, they used a technique called drizzling. The technical nomenclature is: Variable Pixel Linear Reconstruction, or just Linear Reconstruction.
CCD's are used in all types of imaging right down to cheap digital cameras (and expensive ones). The beauty of CCD's is that they can be designed and programmed to capture just about any wavelength of light, from gamma-rays down to radio waves. Of course, in space, comsic radiation is powerful and causes quite a bit of interference and they have to correct for that.
