Think OP is confusing their terms.
Looks like you're cropping the picture (zooming is what you do with a lens when taking a picture).
That smaller section has to be magnified more to fill the same size of print. If it's a tight enough crop (small enough part of the image) the resulting magnification of the noise ("grain" in film days) that was too small to see when looking at the full image is now visible. If you blow it up enough, you'll see the pixels that make up the image. (The size of the noise "grains" varies, depending on how noisy the picture was to begin with, largely the result of using higher ISOs.)
If the image was sharp, the crop is also sharp - it's just noisy for the reasons others have said re: magnifying the noise and possibly magnifying the pixels (dots that make up the image) to the point where you can see them.

If you want to enlarge an image and still have it look good, you need lots of pixels, for one thing. Still, there is a limit to how far you can zoom in and maintain quality.

There was an image posted online. I think it was an ad by Bentley. It was a distant shot of the Golden Gate Bridge. As you zoomed in to the Bentley driving on the bridge, it was still sharp. I found it. Zoom all the way in, and you will see the "B" on the seatback - razor sharp.

Ok, Both me and some of my photos need some clarity. Please tell me why and if there is something I can do diff. When I take a photo and it appears very sharp as is.... even when printed. However, if I choose to zoom in on the subject and then print it it is way out of focus. Very grainy. This is probably a simple issue to some of you. I have not been able to find a solution no matter what I try. THX


Are you using a point & shoot that has digital zoom? Yeah, digital zoom multiples look like amazing things, but digital zoom greatly degrades image quality.
Turn off digital zoom. Don't use it. If you need more magnification in prints, crop and enlarge more.

Cool Trick, but looks like things around the seat arn't nearly as sharp. Notice the door.

Aside from the neat Bentley photo that is “clearly” no pun intended, a compilation of photographs, I suggest you may like to try “Perfectly Clear”software at: http://www.athentech.com

Cheers!

Astounding, I agree. Astounding that someone asks for advise and you guys start gushing over someone else's picture.

On the other hand, attempts have been made, questions have been asked and other comments have been made. All in response to the OP. After 24 hours 9and counting)with no feed back from the OP the conversation has naturally strayed

Clever PP- the bridge is a photo, the Bentley is a vector graphic embedded into the jpg. It will always be sharp no matter how much the zoom is.

The OP responded three hours before you wrote this. We're free to stray without guilt

Bruce nailed it. More pixels is not the answer. That's a just a way companies, trick you into buying new cameras. It has 50 megapixels, so what. They are small. Bigger is better when it comes to mega pixels. Google, it if more is better, find out for yourself.
They are other questions, are you using a tripod? How good is your lens and lastly how far away are you?

How much are you zooming? What camera and lens? Extreme zooms are going to cause images to fall apart, just the nature of the beast. Some camera sensors handle it better than others. There are a lot of factors to consider before you can get a definitive answer. Could you post some examples and be sure to store as original.
