A Load of old crop

[mercmanuk]

In this month's edition of photo-plus a chap explains focal length with he is i think is right but then again i am no expert yet, but is he entirely right of in his last comment about the 1D series he says 21 mega-pixel camera gives better Resolution with out compromise .???? What is the compromise there are only so many colors/image information you can capture my 3M-P Nikon cool-pix gets great shots, my canon 400D 10 M-P gets great shots, but they contain the same information, i mean you can get a large image of 10x8 from a 3MP camera with perfect resolution it has been proven , so is he right,

Is this another?, well if he takes shots for magazine quality you need a zillion M-P camera. or if a 400D had a 21 million M-P software it would take the same shots as the 1D albeit on a cropped sensor, or is this another way of justifying the 4K spend, as we have already proved in thread earlier that a 5D will do everything you need in the full frame range that the 1D's will do, apart from weather-sealing, i think it boils down to purse size and how you imagine you will be 50% of the time with your camera, so is he justified in saying that or was it a load of old MP crop rubbish, if you can find holes in his statement and it get published you win a 4GB card worth a pop i think.

So do more M-P make for a better resolution at 6x4 10x8 then going up the scale till canvas, When dose the image start to loose resolution or another way when dose the cropped sensor start to fail where the full-frame 21 M-P takes over.

If i was a professional Tog which provided me with a income i would get the 1D or better, as i am not relying on my togging skills (thank god) for income a 400D 10 M-P is fine for me, if i have loads of dosh (i wish) then i would get the 1D, so are we being sold this idea or do these resolution theories stack up.

There isn't a simple answer as there are several variables here.

Noise is related to pixel density which in turn can affect clarity/sharpness.

Then there's the whole circle of confusion/DoF issue which is pretty complex too.

Viewing distance from the print also matters.

If you ignore all of that and simply look at the issue in terms of what will give a better print then clearly the higher resolution will win. Once you start cropping and comparing the other aspects the lines get a little blurred. The important thing to remember is that all DSLR available today will give a good print to at least 18x12" and in many cases much much larger so really it's not something you need to lose any sleep over

I agree but this issue causes others to loose sleep as they strive for the ultimate full frame and know the 5D MRKll is on the way well i am looking out for an older 5D there will be lot's as my first time F/F.

It might make a technically better picture but as I said in another thread a few hours ago 99% of the people looking at the shot won't have a clue nor care. Only other geeks.

The only time clients mention noise is when they want a grainy effect in a b+w shot.
