what is the difference between optical zoom & digital zoom in a digital camera?

Answer
One Word, "Cropping".

Optical Zoom refers to lenses actually making the subject of the photo appear to be closer to the camera becasue it magnifies. You still are using ALL of your megapixels four the photo.

Digital zoom is just like cropping. If you zoon in two times, you are making the pixels twice as big, and having half as many of them in your photo. This makes it look grainy.

Any Point and shoot Digital camera that has at least 1.6 Megapixels will do a fine Job when printing a 4 X 6 Inch Photo...

Your 1024 X 768 Pixel Monitor only has 786432 Pixels which is 0.786 MegaPixels.

BUT, the lenses on digital cameras are usually nothing close to impressive in most cases.
They may have a 3X or 4X Optical Zoom Lens. (Ignore digital Zoom, See above and below term "Cropping").

You can only get so close you your subject.
For Example:
My Two sons were playing in the pool on a bright sunny day. My wife wanted my 11 year old daughter to take a photo of both of them My daughter wasted 5 pictures trying to get them both, but my Brat of a 9 year old decided to Jump the other direction to try to mess up every one of her shots.

The Photos were ruined, we all thought. BUT, she was using a 5 Megapixel Casio camera.
I looked at each of these landscape images again. I found that it I cropped out the Brat by turning the photo 90 degrees to be a Portrait shape and getting rid of the 2/3 of the photo that was bad, there was a fantastic image.
This image had 1.66 Pixels left in it which produced a Brillaint 4 x 6 photo of my One son.
The Lighting was perfect, the color was great, the reflections off the crests of the water was breathtaking. There were five little droplets of water that had been frozen in time dripping off his ear and there were 5 little shadows of the droplets on his chest.
The Photo is an award winner that we would have Thrown away if we did not have enough megapixels in our Camera.

More megapixels does not make your snapshots look better.
More megapixels gives you the freedom to look for the hidden beauty in each photo, crop out the bad, and have fantastic quality left in the Image.

No computer monitor can do these two photos justice. Remember the monitor only shows about 1 7th of the pixels in its highest resolution.
If you really want to see what I am talking about, copy both photos to a cd or a memory card, take it to walmart, walgreens, CVS pharmacy, or anyone that does full resolution 4 x 6 prints and print them out. You will KNOW why you want more than 3 Megapixels.

P.S. My daughter age 11 DID win the Blue ribbon with Honors at the county 4H fair with this photo and nine others that she took herself. She also got a Blue ribbon at the State fair, too.

The camera she used has been discontinued, but its replacement is here.

LG enV2 camera quality?

Q. im planning on getting an enV2 (my first cellphone, ha, parents finally allowing me to have one) and according to some of the reviews I've read, the only bad thing about it that bugs me is that the camera sucks. Is it really that bad? It doesn't have to be top notch or anything, I have a regular digital camera for that, but I want it to be atleast somewhat decent. It's a 2.0 megapixels. Is the camera honestly that horrible and can anyone show me a picture taken from the enV2 i can look at?
ive seen a couple pictures, but i dont think they look bad. but theres several reviews saying the cameras bad.


Answer
Dont listen to the reviews. The Env2 has a very clear 2.0 MP camera. The main downside is that it has no flash, that's what the reviewers could be complaining about. And the zoom is hidden from you(you must lower the resolution of a pic to access zoom). Dont get me wrong, the Env2 will not fill all your picture taking needs(you might as well carry around a small digital camera with you for serious pics) bu the camera is decent
