I was just wondering if there was some truth to it. Not that I believe everything he writes... or even most of it.
But it's not the first time I've heard/read it. That some cameras produce "sharper" files at lower megapixel settings, I mean.
There's always truth to some of the things he says but usually it's for all the wrong reasons. For instance he says it's because beyer interpolation is not needed. That's just bull****. If you didn't do beyer interpolation on the data coming from the sensor your pictures would be green. This is because there are twice as many green pixels as red or blue. There are countless cameras out there with sensors in a beyer pattern that produce excellent photos.
The reality is that the sharpness of the sensor is based on the filter infront of it, and the light hitting it. Ok these days low pass filters are excellent performers, but at 21mpx you need the bloody sharpest lens you can buy to get the full performance from the sensor. Even with a 12mpx camera I can see a huge difference in quality between my lenses and most of them aren't cheap. 21mpx makes this even more important.
As for the real reason pictures look sharper it's all to do with image processing. E.g. suppose you have 3 pixels in a row:
black grey white white.
This isn't sharp. The transition between black and white happens over 3 pixels. But if you halve the size by taking every second pixels:
black white
perfectly sharp transition now isn't it.
This is somewhat akin to printing out a picture that isn't sharp, hanging it on the wall, and then looking at it from the opposite side of the room. Sure from that distance away it looks tac sharp.
But this is all just semantics because quite frankly if you buy a 5DMkII and shoot at medium you deserve to have a dog bite your testicles off. Shoot RAW (unless you have a good reason not to) and then resize the image in post processing.
I'm at home sick. It's a sad day for me. But man you made it so much better.
Btw you owe me a new keyboard this one now has coffee all over it.
**** man now i'm crying too. :lmao:
