Things To Know About Camera's & Mega Pixels

Well, really... once you get to a certain point (3.2 megapixels, in my opinion) you're only going to see a REAL noticeable difference when you blow the pictures up.

More megapixels = the larger you can make the print. I think that's really what it comes down to.

As far as numbers go, you are correct. However, a 5 megapixel camera with a good sensor and lens trumps an 8 megapixel with a sub par sensor and lens.

Good info here, thanks guys!

C'mon now guys, be nice.

I'm sure if you have more megapixels it will allow you to blow up the picture bigger, but as dude just said, beyond 3 or 4 megapixels it's not gonna look drastically different if it's in small size.

Exactly. I took an 8MP photo and it looked like fuzzy, blurry trash. You have to reduce it and fix it in photoshop before it looks halfway decent. However, I realize that for a smart-phone...the picture quality is acceptable.

What this means is... an 8MP image has more detail than a 5MP image.

Not true. Just because it has more pixels does not mean it's more detailed. I can take a picture from a 1 megapixel camera, and increase the pixels to make it an 8mp size. That doesnt mean there is more detail, the same detail from the 1mp picture is there, nothing more.

However, a 5 megapixel camera with a good sensor and lens trumps an 8 megapixel with a sub par sensor and lens.

Absolutely correct.

 

[NeoteriX]

But one thing is for sure... an 8MP image has 3 million more pixels of detail than a 5MP image.

The amount of "detail" that is digitally recorded by a sensor is irrelevant if the lens in front of the sensor cannot resolve that much detail.

All I was trying to do here was to pass along some basic information about digital images to people who may not be clear on it, and some of you people are acting like a linch mob.

Man!!!

It's a simple and basic fact that if you took the exact same picture with an 8MP camera and a 5MP camera, the details of the 8MP image would contain more pixels. This means more detail.

It does not matter how big or small you make each image, the 8MP image is still going to have more pixels, thus have more detail.

Sure you can run a process on a 5MP image and turn it into an 8MP image, but I am talking about the image that the camera takes and not what you can do with images.

And I'm not saying anything about one sensor being better than another sensor or one camera being better than another camera. The iPhone 4 camera may very well turn out to be a better camera, but that does not change the fact that an 8MP image has more detail than a 5MP image.

The contradictory nature of your post makes me crazy.

How can you try to ignore sensor types and which is better then say 8MP will always have more detail than 5MP?

I don't have a high hourse. In fact, I'm more of a trailer trash guy. I posted this thread to try and help people with some basic facts about digital images, and you come along with your... "make it up as you go along"... information, and throw confusion into what could have been a helpful thread.

Maybe your the one with a stick in your ass.

ROFL, come on now, this thread wasn't helpful to anyone. Anyone can google "megapixel" and get this information. Anyone that has an IQ greater then 50 would put the photos up side by side on a computer screen to compare instead of comparing on their phones.

A useful thread is one that either:

1. Contains information not easily accessible through a search.

2. Bundles up a lot of different information accessible through a search into one convenient thread.

3. Asks a question that others may have and has not been asked or answered before.

An 8MP picture is about ten times the size of your average monitor set a reasonable resolution. So unless you're using a projector as a monitor or have a three foot roll plotter, the additional detail is essentially useless.

You can't just shrink the picture size to 5X7 and expect your monitor or printer to be able to capture the 8MP of detail. No consumer monitor or printer can display that kind of resolution.

For all intents and purposes, and if you don't expect to crop your photo, a 1MP photo displayed on your monitor, or printed at a reasonable size (8X10, 5X7, etc) is going to look exactly like a 8MP photo, keeping all other things equal.

If you need resolution beyond 1MP, then you need a real camera, not one on the back of a phone. Camera phones are used for taking pictures of friends at the bar, not particles in the Large Hadron Collider.

I apologize for what I said, but it is INCREDIBLY condescending to accuse me of "making up" things as I go along... TWICE now, in fact.

I didn't make anything up. It's simple logic. Yes, of course 8 MP is better than 5 is better than 1. But for all intents and purposes, it DOESN'T MAKE A DIFFERENCE for the typical everyday user who is making prints. It doesn't start to really make a difference until you blow the picture up... and really, I don't think that most people are going to be enlarging a snapshot from a cell phone too often.

And no, I didn't make anything up. I have taken several photography classes. I own a nice camera. No, I don't do it for a living. But I am not completely inexperienced and I am NOT making anything up, and I find it incredibly disrespectful that you're accusing me of doing so.

I'm allowed to have an opinion that differs from yours. I never accused YOU of making anything up (although your "information" is so selective that it isn't very helpful in the first place), so it was awfully defensive and condescending of you to do so yourself.

EXACTLY. This is exactly what I was trying to say.

You do realize that just because Steve Jobs says it's the best, doesn't mean it actually is, right? The technology Steve Jobs went on and on about at WWDC in the camera of the iPhone 4 is actually very close to the tech used in the EVO's as well.

As far as numbers go, you are correct. However, a 5 megapixel camera with a good sensor and lens trumps an 8 megapixel with a sub par sensor and lens.

However, an 8mp camera with a good sensor trumps a 5mp camera with a good sensor.

Woo.

 

[horadin]

Every pixel is a detail of the image.

5MP image = 5 million details
8MP image = 8 million details

8 - 5 = 3

There are 3 million more details in an 8MP image.

I don't know how much more simply I can put it.

I don't think you understand that MP is not the only determining factor to detail. Lens and sensor quality have a huge roll in this.

I don't know how much more simply we can put that the only way to see the additional detail is with a projector screen, an roll plotter, or zooming way in on the picture, and none of those things matter to people taking picture with a camera phone.
