Your calculations are way off like I said going up by MP's is not based on linerality. The difference from 8MP to 12MP is NOT 50% lol.....

My calculations are not 'way off', I have proven them to the individual pixel two ways. The method you cited is so oversimplified as to be ridiculous as well as 'way off'. How can you remove 1/3 of 12mp but it only really removes less than 1/2 megapixel? Answer: do the math entirely wrong with a faulty formula, and don't question something that on its face is suspect.

You're making things more complicated than they need to be with your sketches and calculations as they even confused me but I'm not mathematician. We're talking about resolution size here not a straight pixel amount linearity.

No, I have shown why your claim of 406272 is grossly over-simplified. My sketch plainly showed where that incorrect number comes from and why it is incorrect. It's not rocket science. It's just common sense. The formula you cited was oversimplified and resulted in a nonsense answer, plain and simple. Why cling to something that's been shown to be wrong?

We're also forgetting to mention that you can upscale photos to have more pixels IE you can make a 12MP photo 18MP if need be......more MP's DOES not equal more data & better image quality or else there would be cheap point and shoots that shoot better photos than full frame cameras with L primes. It's much, much more complicated than "lets just add more megapixels" Megapixels are primarily a marketing gimmick to get more mainstream consumers to buy their cameras.

You have to factor in the sensor, lens, and many, many other complicated things that revolve around these two things.

Up-sampling 12 mp to 18 mp does not produce 18 mp worth of image data. Yes, more MP is a marketing gimmick at sensor sizes where they cram too many pixels on a small sensor. I agree with you on that. However - 18mp on my new(er) Canon will allow me to do crops that my 12mp Canon suffered under.

Do people really spend \$700 on a camera so they can take a picture of a squirrel or a duck?

If that's the case how come my 450D produces sharper photos than from what I've seen from most 7D's and the other newer crop bodys? The new Canon sensors are cramming MP's in. I can upscale my 12MP sensor and get the same results. The 5DClassic at only 12MP will even produce sharper and better photos than the 7D with it's 18MP crammed sensor.

As for your formula, it's wrong. Take a look at my formula we're comparing resolution sizes not MP's directly. Comparing resolution size you end up with like a 20% difference from 8MP to 12MP.

If we we're just comparing pixels to pixels sure the difference might be 50% but it's not. We're talking about resolution size here MG's stand for a resolution IE 12MP stands for such and such resolution.

I'm not going to take a second look at your formula as you're over complicating things when it's really as simple as one resolution size vs another.
