digital camera megapixel question?

lor

is higher megapixel the better? (image quality)
because i have a 2 mp camera and my brother has a 7 mp camera....when i compared the difference of photos.....i don't see any difference!.....
so that made me wonder???
i heard 4 or 5 megpixels are good enough for everyday pictures.....

Answer
In general higher resolution (more megapixels) means better image quality. There may be situations where that isn't true (i.e. where the higher resolution camera has a low quality lens and the lower resolution camera has a great lens) but generally more megapixels = better image quality.

There may be several reasons why you're not seeing any difference in the images.

1. Many times I've seen people unknowingly using cameras at lower resolutions than the camera is capable of. That lets you put more photos on your memory card, but the quality will be lower. If a 2MP camera and a 7MP camera are both set to 1MP resolution, they're going to look pretty much the same. Check to see if both cameras are shooting at their highest resolution.

2. If you're viewing the images on the camera display or on a PC screen, the resolution of the display or screen is far lower than the maximum resolution of the camera, so you probably won't see any difference. If your PC display is set to 800x600 resolution, that's less than 1/2 megapixel being displayed, so the images will look pretty much the same. Even a 19" monitor set to 1280x1024 is only about 1.25MP, so that's still far less than the maximum resolution of either camera.

3. If you're printing photos at 4x6, you probably won't see much difference. The differences will show up when you get to larger prints like 8x10 or larger. Like with the screen, the smaller size of the print isn't going to show the differences between the cameras. Large prints usually will show the differences.

If you're doing any image editing, having a higher resolution camera can be important. Say you have a photo of Uncle Frank at the beach and you decide you want to crop it down so that the lifeguard stand on the right and that goofy kid who jumped into the picture in the background on the left aren't in the photo and all you have is a nice close-up of Uncle Frank with the sand and water behind him. When you crop the image to only show the parts you want, you're reducing the effective resolution of the photo. If you crop out 1/3 of the image on the right and 1/3 of the image on the left, what remains is only the center 1/3 of the original image. If you shot the original at 7MP, that means that you have about 2.33MP left, because you threw away 2/3 of the image. If you shot the original image at 2MP, that leaves you with only about 0.67MP. You'll probably notice the difference between 2.33MP of image and 0.67MP of image in a 4x6 print.

So if you're going to be doing any image editing and/or printing at larger sizes, having a higher resolution camera may be a good idea. If you're doing just snapshots that you'll be printing at 4x6 or maybe 5x7 or just viewing on a PC screen, then you may not see any benefit to having a 7MP camera over a 2MP camera. And if the 7MP camera is set to shoot at a lower resolution, then there may be no difference at all.

Cheap 10-megapixel camera?

Tiffany

I was reading a Magazine at work called 'Quick&Simple' and it featured a 10-megapixel camera that was at a lower price than most on the market. If I remember correctly, it had a 'CX' in the name. I cannot find this camera or the magazine it was featured in. Any help would be very much appreciated.

Answer
Here's a listing of cameras 10 megapixels or better:
http://www.imaging-resource.com/DIGCAM12.HTM

I didn't see anything there with a CX in the name.

However, there are a number of very good cameras on that list; I would find something in your price range and go from there. Note that you should check for the most current prices, as camera prices change just about daily.

Among some good cameras at low prices the

Casio EXILIM Zoom EX-Z1080 and the Fujifilm FinePix F50fd

are both worthy of being looked at.

What is the size of printout you can get from a 2 megapixel camera?

Understate

For a 2 megapixel camera , what is the size of photo can you get ?
Similarily , what about a 3 megapixel camera, 5 megapixel camera
and so on ?

Answer
You can get any size of printoutfrom these cameras (in theory). In practice it is a question of quality. Assuming that your printout has a ratio of 10/15 and the pixel size is P, the pixels ler line that you will get is sqrt(15/10 x P). To get a good print this should be at least 200 pixels per inch. For 2 megapixels, this means about 1700 pixels or 8.5 inces, for 3 megapixels 2120 pxiles or 10.5 inces, for 2700 pixles or 14 inches. Note that in practice, godd printing softwares will extrapolate actual camera pictures and eventually allow for good prints at larger sizes. In addition the quality of the actual image will have an impact on how a print will look like, i.e. a 2m picture from an expensive professional digital camera will look much better than the same picture from a cheap mobile camera at the same size, simply because of the quality of the image captured.

How many megapixel camera should I get for a Digital Media Course?

Natalia

I'm starting a course in three weeks time that is basically all digital stuff: including photography. I would like to take the photography path as we were told to choose between game development (not very good with writing programs) and photography.
So should I get a 14 megapixel, 16 megapixel or 20 megapixel camera (I had a look an I'm quite keen on the Samsung Smart Camera 16 megapixel camera but I first wanted to ask how many megapixel camera I should get.)

Thanks in advance!

Answer
Zero mega pixels is just about right. YES, I am kidding, but I am just trying to drive home the point that mega pixels do not matter any more! All cameras produced for the last several years have enough mega pixels to produce great quality prints. BUT you must always set you camera for MAXIMUM RESOLUTION. How do you do this? With most cameras you enter the "menu" function and scroll through until you come to the "pixel" setting. ALWAYS set you camera for greatest number of pixels and leave it there! But you want small files for email etc. You should get your yourself a small program for your computer, where you can save your picture for email (using a slightly different name of course).

More important is the length of the zoom lens. You want at a minimum a camera with 5x optical zoom lens. A camera with a 3x zoom lens is useless, and you will wish you had at least a 5x with in a couple of months. You didn't mention a budget for this purchase so it is hard to make a recommendation. Samsung are ok cameras. But Canon, Fuji, Nikon, Pentax are really the names to strive for!

P.S. You said nothing about a DSLR, Digital SIngle Lens Reflex camera like someone else recommended. That is like buying a ladder with 5 of the 6 rungs remove! Too much camera for your level at this point.
