Фотографирање - совети и искуства

The very short answer is that there are around 20 million "quality" pixels in a top-quality 35mm shot. That's a shot with a tripod, mirror-up, with a top-rate lens and the finest-grained film, in decent light. 12 million are more typical for "good" shots. There may be as few as 4 million "quality" pixels in a handheld shot with a point-and-shoot camera or camera with a poor lens. And of course if focus is poor, or light is poor, or the camera was not held steady, the number will drop down below the 1-2 million pixels of the modern consumer digicam. Of course, one can have a bad shot with a digital camera too, not using all its resolving ability. However, few pick their gear with the plan of shooting badly.

The eye, however, is not as discerning when looking at a picture in the usual context as it can be when looking at things blown up. So many can also argue that a shot of around 9 million pixels would look as good to the eye as a 35mm shot, except when blown up very large and looked at quite closely.

It's important to note another key difference. Film, as an analog medium, does not record just 256 grayscales or the corresponding 16 million colours. And film scanners, even doing just 8 bits per colour, get 24 bits of data for every single pixel. Today's digital cameras only get 8 bits of data for each pixel and they guess (interpolate) the other 16. So the colour accuracy for even a scanned film image is better than the modern digital camera. Good film scanners can also extract more than just levels from 0 to 255. They can often go to 12 bits (0 to 4097) to detect much more detail in shadows, and provide more contrast. As such a film scanner gets as much as 36 bits of information for each pixel, instead of 8.
 
More modern digital cameras gather 10 or even 12 bits of the single colour pixel, and keep it if they record in RAW mode, but reduce it in JPEG mode. Foveon digital cameras record all 3 colours per pixel, like film, but their sensors have lower resolution as of now.
 
As a counter note, the 24 bits of colour from a film scanner, while better than the 8 to 12 bits per sample of a bayer-interpolated digital camera, is nowhere near near 3 times as good as some pretend. The interpolation algorithms are good, and rely on the fact that to the eye, particularly in natural scenes, position-brightness information is much more important than colour information. How much better full colour information is is subjective, but it's not even close to 3 times better. On the other hand, even the 36 bits from the best scanner is not enough. The film has much more information.

Can they get a better shot with a 35mm chrome than an 8MP DSLR? Probably, but only by a small amount. But the DSLR is just so much easier to work with, and so much more flexible that when the final goal is digital (as it almost always is today) the choice for these photographers is not very hard.

Someone asked "If I got a camera with only 6 or 7 MP, can I make good pictures with it?"

Buying a Bösendorfer doesn't mean you can play the piano. Buying a great camera doesn't mean you can create compelling photographs. Good pianists can play on anything and a good photographer can make great images with a disposable camera.

"Leica, schmeica. The camera doesn't make a bit of difference. All of them can record what you are seeing. But, you have to SEE."

Knowing how to do something is entirely different from being able to do it at all, much less do it well.
