Megapixels

When buying a new digital camera, vendors are trying to convince you to buy a camera with the most Megapixels(the highest resolution). But is this always necessary?

Do people even notice the difference between images with different resolutions?
David Pogues, a writer for the New York Times, conducted multiple tests on this subject.[1]

These tests showed that only 6% of the people could distinguish different resolutions of the same image printed on a 16 x 24″ ( 40x 60 cm)paper.
He chose this size because according to him most amateur photographers wouldn’t often print images larger than that size.
The resolutions shown were 5, 8 and 13 Megapixels.

So do you think that, for amateur use, digital cameras with high resolution are useful?

One response to “Megapixels

  1. i think digital cameras with a high resolution aren’t useful, unless you are located at the south Korean border taking picture of the north for espionage purposes and need a huge amount of digital zoom to see what you want to see. higher pixel numbers is just a marketing trick to sell a camera for a much more expensive price. look at the new Ipad HD for example. it has a resolution of 2047 x 1536 pixels, or 264 pixels per inch. this is much more than the human eye can perceive and is thereby not needed (unless you are using magnifying glasses to look at the screen), but gives people who don’t know this the idea that the 500$ they pay for it is justified.
