why does a high MP camera makes low MP pictures?

Q. I have a Sony T70, which is a n 8 MP camera. I set it to the highest settings, so it would take 8MP pictures which I can enlarge, but I end up with 2 or less then 2 MP pictures. Why? I am not using the zoom either. What is going on? Does anyone know what am I doing wrong?
Yes, I meant 2MB pictures. The reason I was concerned is beacuse I had a 7 MP camera which made pictures of 4.5 MB, so I figured this one with the 8MP should make at least the same size pictures. But I guess not, maybe Sony makes different cameras, the 7 MP was a Casio model.

I wonder if you mean MB for the size and not MP. Higher mega pixel sensor can take images in smaller resolution. Cameras use compression to make the file sizes smaller. It is possible to have an 8MP image that is only 2MB in size. You should check the manual for compression settings and adjust for the highest quality lowest compression ratio. This will give you the big files you are looking for.

Based on your added information, it's the compression. Different cameras use different compression ratios. A ratio of 1:4 would be quarter sized while 1:2 would mean the file is compressed half its size without compression. Check your manual for any options on changing the compression. The lower the compression, the larger the files and the better the overall quality. Highly compressed images tend to be significantly less sharp and contain more digital noise.

What is the benefit of higher MP in a digital camera?

Q. So I used to have a canon camera 7 MP, and then I converted to Nikon cool pix 12 MP. However I wasn't satisfied with the results from Nikon as the picture's quality was not THAT good and it mainly just went indept of the face and hair.. would show like any pimple on skin, etc. Canon was a good balanced camera, with great quality. So this left me quite confused, what is the use of higher MP? I'm thinking of purchasing a sony cyber shot either 16 MP or 18 MP. Please clear my confusion, and recommend me any other good digital cameras aswell. Advices/tips are most welcome.
Thanks!

Answer
- More MP = larger image dimensions
- Blur that would not be noticed at lower resolution will be more visible at higher resolution
- Smaller photosites can potentially reveal finer detail (with a sharp lens), but also suffer more noise since individually they capture less light
- Different sensors capture colors differently

Resolution *does not* directly affect sharpnessâthat is the job of the lens and fast shutter speeds.

If you still have your Canon, why not stick with it?

I want to get a 12 mp camera but it says that at high iso settings the noise level is huge.
If i reduce the pixels to say 8mp, does this mean the noise level will be reduced at higher iso settings?

Answer
High MP point and shoot cameras have been foisted on the public by the manufacturers because most people think the higher the MP number, the "better" the camera. Nothing could be farther from the truth. The more and more pixels crammed on the tiny sensors of point and shoot cameras only cause more problems than they solve. Yes, high ISO settings give horrible results, because the tiny pixels cannot gather light as well as the larger pixels on a larger sensor, such as on a DSLR.

As stated before, you need to NOT use high ISO as much as possible. Usually point and shoots get looking pretty bad at anything over ISO 200 to 400.

Use a tripod and keep the ISO low if you want good shots in dim light. Just be sure the camera is not set to automatically raise the ISO in dark conditions.

w? are advanteges of buying 10 MegaPixel cameras instead of lower MP cameras?. any disadvantages with high MP?

Answer
If you always plan to compose your pictures perfectly, you don't need a whole lot of pixels. These days, I'd say that 5 MP or even 4 MP is fine for the average snapshooter and this can be obtained without unreasonable expense. If you want to allow for cropping, which means enlarging only a portion of your image, the more pixels the better.

Imagine taking a scenic view and then noticing that the middle 20% of the photo would make an even better picture. Suppose you take a picture of a whole group of people and Aunt Clara really, really looks great in the picture, but everyone else looks lousy. If you have the pixels to work with, you can still make a decent print of Aunt Clara that she would be happy to have. If you buy an 8-to-10 MP camera and don't want to TAKE large photos, you can always set the camera to a lower file size. You can never go the other direction, though.

Unless the cost is a major issue, buy the camera with more pixels. You will never be sorry that you did, but you might one day be sorry that you didn't.

Having said all that, though, pixels are not the only measure of image quality. The sensor size is important as well as the image processing softare included in the camera. You need to read reviews if you want a critical understanding of image quality for particular cameras. Try http://www.dpreview.com/reviews/ for more information on the cameras you are considering.

Does MegaPixels offer the best quilty in photos?

highest mp for camera image

Rico

Lets say you have two photos, they are the same photos. one is a 13.1 MP and the other is shot with a 24.6 MP camera. Will the high MP camera offer the best quality? If not, what offers the high quality that makes photos look like glass, HD, the best of the best?

Answer
Yes and no. In today's cameras, the answer is largely no. But the answer is not simple. There are many factors that affect quality. Some have already been mentioned. Not mentioned is that sensor technology has improved in ways that are unrelated to pixel count. An 8-megapixel sensor today (if you can find one) will be much better than the same size from five years ago. As a general rule, the more pixels you have, the less light there is to share between them. This harms low light performance. However, the technology has improved so that today's sensors use the light more efficiently. Another factor is the quality of the in-camera processing before you even see the image. The more expensive cameras have more powerful processors and better software.

So it would be a mistake to purchase a camera solely on a comparison of the megapixels.

I can't leave the topic without mentioning that by far the greatest factor in quality photography is the skill of the person holding the camera. Most people who buy cameras today do not have the skills to take full advantage of the camera's capabilities. Another way of looking at this is that it won't be your camera that will limit the quality of your work. It will be you.

Would i still look as good as i do in a diff camera?10 POINTS?

Omar

I have a 5 MP camera. And look alright, but I'm guessing that I would look worse in a better higher MP camera, I look best in the mirror, better than I did on cam. Also is it bad if I only look good in a well lit area, or just descent?

Answer
Flip UltraHD Video Camera - 2 Hours (3rd Generation) NEWEST MODEL is a powerful, easy-to-use, fairly cheap video camera; it records @ 1280 x 720, 60 FPS, and can hold about two full hours of video at that capacity. It fits neatly in a shirt pocket and is pretty much ideal for recording anything that doesn't need to be professionally produced film, from home movies to recording interviews. It comes packaged with a basic editing program that's designed to make it as easy as possible to produce basic home movies and post them to the web.
