i was reading about night photography and the guy said he took 10 30 second images and stacked them into one image,
why can't just one picture be taken?
what happened in the time before digital?
did the photographer take 10 shots with film and stack them?
I'm tempeted to say the days of film produced proper photographers but that would be a bit controversial ...................... wouldnt it?
You can cut and stack negatives too
Not controversial.. just plain insulting IMHO but i imphasis IMHO
so digital is easier in as much as you can delete and keep trying the same day etc and they also have so many features.
did/do film cameras have all the advanced settings of digital or was a lot of it due to film selection and processing?
What you couldnt do was change settings such as ISO (film speed) mid shoot to adjust to changing light conditions.
In reallity digital opened up a whole new ball game and now produces a different type of photography and photographers.

i suppose that megapixels came along with digital then?
were megapixels used at all in film?

If you weren't serious, I would have laughed so hard, but I can see sincerity so the answer is this: Pixel is used only when referring to digital imaging sensors. A pixel is a group of four light sensitive diodes (light sensors) 2 green, 1 red and 1 blue this mimics human vision which is more sensitive to green light. Mega is the SI prefix for million, so one megapixel is the equivalent of 1,000,000 pixels or 4,000,000 light sensitive diodes. As film does not use light sensitive diodes, it only applies to digital and is used to quantify the quality of either digital sensors or digital displays.i suppose that megapixels came along with digital then?

RUBBISH.:bonk:
Of course you could change films midway during a shoot. Not on a single 35mm body, I grant you, unless, as most photographers of the age did, you loaded different camera bodies with different film stock. On medium format cameras you simply changed backs,

Take a minute to think about what you've just asked...
Of course, as this pic from Canon's R&D depot shows...........
You can do a lot with film if you know how, manual processing of film can be very complicated and long but the results can be the same (in most cases) to what can be done digitally.
Burning, dodging, exposure and all other techniques made digital came from film.

Rubbish eh? :razz:
I never mentioned changing film stock either by re-winding (on 35mm) or swopping backs on MF. Maybe what I should have typed was "mid film" in stead of "mid shoot). But my reference was aimed at changing the ISO rating as we do with digital.

A slight correction...
A single pixel is just that, one pixel, not a group of four. The 2 green, 1 red and 1 blue you refer to relate to the Bayer Filter over the array of monochrome sensor elements.
Each pixel is filtered to record only one of the three colors. Each pixel cannot fully determine RGB color on its own, only red, green or blue. To get the full RGB for a given pixel a demosaicing algorithm is applied to interpolate a the red, green, and blue values for each point.
The exception to this is Foveon sensor technology which uses a layered approach to the sensor element which captures all three colours in a single pixel.

right i may have found a better way to explain what i want to know now lol
say i wanted to put a big photo on the side of a double decker bus
presuming im on the right track i would take a picture of the object with a digital camera with a high resolution ...... yes?
then when i blow the picture up to the size of the bus it would still look good because its high resolution ie:- megapixels?
but what would i have done if digital cameras were not invented?
could you still do it with film?
i am not taking the mickey here folks im really intrigued
I still think shooting film instilled a discipline during training that's lacking with those wholly brought-up on digital capture.
I'm constantly amazed at the lack of what I always thought of as basic photographic skills and techniques exhibited by photographers I meet on my travels (mostly Press toggers, I have to say).

I think he's right to a certain extent - not that digital hasn't produced 'proper' photographers either, but the majority of photographers whose work I admire were 'weaned' on film.

I can see that being quoted in somebody's signature.
a question is only easy if you know the answer.
