Are High Megapixel Cameras Really Better?

Photography/Digital Camera

i used to own a samsung digimax 301 digital camera 3.2 megapixel, i have used it successfully without any complaint, but recently i bought a samsung S 800 an 8.1 maga pixel i can not see any marked difference apart from additional functions. what is really the difference in these mega pixel? is it worth the waste of money at all? photography buffs i need your input

@ cute_N_hot

you are not wrong, iso settings, aperature, lens etc have a bearing on the outcome of the image from a visual point of view.

for example one can shot with a 12MB digital slr, but due to camera shake end up with a blurred image, this doesnt mean the image isnt crammed with info, it is just crammed with 'bad' info. This image can be enlarged to A3 without any pixel degradation which wouldnt be possiblw with say a 2MB camera.

If the image is in focus, a 'perfect' shot, then the larger the MB content, more than often the sharper the image and the more versatile are the possible uses, enlargement, full page magazine use etc, lots of NG publications carry images of poor quality, TRUE LOVE is a perfect example of good image use.

Hope this helps some

I'll rather focus on the size of the camera sensor rather than the MP. A larger sensor with a smaller MP turns out better images than a small sensor and an over crammed MP. Enter Analog camera : their large sensor [35mm] is yet to be accurately replicated by their digital counterparts. You need some 30MP digital cam to come close. Get some good film with the right speed [ISO], and bet you, your pics will come clean [of course with a good 'washing' and printing shop ]

That's in the range of High-Definition Cameras. You also need a huge amount of memory space to store pics on that level

better still,

you can download pixresizer or MS power toys(it includes a picturer resizer that it adds to the context menu).this will enable you to quickly resize pictures.

@ awoof

a lot of higher end digiatal camera's give you the option of selecting the image quality/size.

i use a digital SLR which gives 6 or 7 different images sizes/ quality.

As earlier stated by many, the smaller the image size(MB) then the greater the chances of pixelation when blown up or enlarged, stick with whatever resolution is required depending on the final use of the image.

On the average a 4 or 5 meg image is more than adequate for a 5x7 photograph, if images are for print, say brochure or mag u might need a higher resolution depending on how big the image is going to be in the publication.

Enjoy!!

It's real simple,

If you're not a Graphics expert who needs pretty high resolution images for his work, then it's a big waste getting an 8.0 megapixel camera for casual pictures. Believe me, there's a big difference when you blow up the images to max. size especially for billboards and stuff.

Kinda like using a Nokia N-series phone for nothing more than phone calls, sms and alarms. Just get a 3310 and do something more productive with the rest of the cash! Cheers

abstarr & vebocity are spot on.

If you dont need high rez images adjust ur camera accordingly, 4 individuals involved in graphics there is always going to be a need for high rez shoots or the requirement to 'zoom' in.

but for family snapshots a point and shoot will suffice

the greater the pixel size, the higher the resolution u can get. In english, that means that a picture with a high resolution can get a greater "zoom in" with clearity than the one with less res.

You have not wasted any money. The fact is that the 3.2MP camera was probably OK for you, that is, for casual photographing. The 8.1 is needed when you want to go more professional. For your information, I have a 5.1MP camera, but I adjusted it to take pictures only at 3MP. I'm OK with that since I use it only for casual photographing. Besides, the higher I set the megapixels, the quicker my memory card will fill up.

I think the point has been made by a few posts here and it all depends on what you wnat to do with the images you have from the camera. If you are going to be using the image on any platfrom that that5 is very large like a billboard or big banners, you may consider a higher pixel camera. You may not see the difference if you put two images from diffrent camera resolutions except you are using an application that allows you zoom into the image at a pixel level.

I think hat happens mostly is that people buy camera based on the mega pixels rather than the functional. For many, it is like buying the latest model of a car. I am working on a brochure on my laptop that filled with images that are barely a post card size but shot as if they they are going on a billboard. you can them imagine that just thirty pages of the book is alreday 1.5gigabyte!

The larger the MB size of an image, the more information is contained in the image hence a sharper higher quality image even on a 5x7 print. As mentioned in an earlier post, the larger MB image does have the ability to be enlarged without pixelation occuring (within reasonable limit).

For full image control, dont purchase a point and shoot camera, if finances allow get a digital SLR which will give real control over the outcome of your images, a camera where one looks through a viewfinder and not an LCD screen

The difference is in

1. the printing. if you are not a professional photographer and you hardly print pictures larger than 5" x 6" (postcard size) then you will not notice any difference apart from the buttons on the camera.

2. the Zoom. If you love to take pictures from afar, you will definitely notice the difference as the megapixel increases.

Believe me a good quality 8 mp camera will be miles ahead from a 5 mp one, apart from the extra functions you get the images will be much clearer, you may not notice it untill you blow up your images to say A3 size or larger.

Always go for a camera with an optical zoom if you want reasonably good photographs.

If you can afford it go for a Digital SLR Canon & Nikon make some very good ones.

It is true that when u have a camera of may be 5 megapixels and more,you can't really get to know the difference as it can only be seen on maybe a very high-powered colour monitor or printing paper but i think u are looking at the pictures on a normal screen pr printing opn a normal paper.

i think the ultimate diff is the dimensions of the pictures/video files.

on a 1.3 megapixel camera,

you have a choice of resolutions/picture sizes up to 1300 x 700 pixels.

so for an 8 megapixel camera, you concievably could have options up to 8000 x 8000 megapixels.

the question should always be:what do i want the camera for?

casual photography , surveying, creation of billboard quality images.

the answer will determine the megapixels you require.

one problem with big picture files:they will take up space on your hard drive.

I once read somewhere that after a certain number of megapixels, the images are so fine that the human eye can no longer distinguish any difference.
