- photograph -
"-graph" of "the light" is a meaning called "the thing which was able to work" of "the (I write it draw it) to write", and photograph (a photograph) "photo-" cannot always deny "an image of the light" and the opinion that I was able to translate in total.
However, the coined word of the meaning "that light did not copy it in Japan and represented the scene" in was performed.
From "photograph", I can call it a photo for short.
When it is electronic data of the digital photography, I call the photograph an image.

As competition with the television intensified for the photographers such as the journalists who worked in the distant place from a photographic process institution, you have to have come to dispatch an image to pick up on the newspaper by time when you had a short it.
On this account it was natural for the journalists who worked in a distant place to carry a tool to send an image in a photograph developing set and the telephone wire of the small size at one time for period, and it was it with a big burden.

When I compare digital photography with a film photograph, I am apt to think how much it is when I convert a film into the number of the pixels of the imaging element, but at first both are too different above all.
When it appreciates the last print, will not it be a film photograph that I can bear appreciation at the time of the proximity?
There is the person saying that there "is not it with a thing the print approaches, and to look" at, but there are the classic pictures when I think about a case, for example, to appreciate a picture when even a particularly large-scale thing is surprised at drawing with a feeling of accuracy at the time of the proximity.
I do not need to mean that it must not come close in appreciation directly at least that a work is large.
It is not easy to compare resolving power with a film with digital.
The measurement of the resolving power depends on various conditions.
In the case of a film, I depend on dimensions / the size of the film, the performance of the films such as granulations, the performance of the lens which I used.
Because there is not a pixel on a film, the resolving power that I measured as the thing which there is a pixel on a film is only an aim.
Image processing algorithm to use between assistant, the effect of (Bayer pattern) of the sensor filter of the sensor image, a record picture are related with the digital camera.
In addition, as for the arrangement of the pixel of an imaging element and the display unit of the digital camera, there is a case to produce moire to have a regular repetition pattern, but the exposure particle of the film does not have such a phenomenon to line up irregularly.
The resolution evaluation of the photograph which I photographed with 24*36mm (Leica) seal camera is various.
For example, there is evaluation of ten megapixels.
When it uses the small film of the particle more, this number stops, and it is possible that the use of the optical system of the inferiority and inferior illumination lower this number.
This evaluation connotes evaluation that the latest digital camera is superior to the Leica size camera of 2007.
But the 35mm film is a format for general consumers.
There are a medium camera, a large size camera as a film camera for professionals.
I will have resolving power superior to the current latest digital camera in 2007 when I cover these with former numerical value simply.
As for about 36 film photographs of 6*4.5cm size, megapixel, 4 X 5in size about 130 are megapixels to be concrete.
About 540 8 X 10in sizes become the megapixel.
However, there is the evaluation of 20 megapixels and seven megapixels, too.
20,000,000 pixels of equivalency was calculated from the size of the silver particle for the low sensitivity of the ISO50 class, and the Leica size film watches space frequency effectively, and gradation of the color having a flat characteristic the; is almost around 40%, and about around 8,000,000 pixels, are right by the details description of the thereunder is in proportion to space frequency, and deteriorating.
After all it may be said that I cannot doubt this seeing from a limit of the physics such as the equal thing of the film exposure particle and inhomogeneity of the size or the blur of the focus by the thickness of dispersibility / the emulsion layer.

As for the resolving power of the modern ultra-fine particles black and white film which I photographed by an ideal exposure with a high-performance lens, suitable with detail is provided in file size more than 30 megapixels.
Even a cheap Leica size film camera (a compact camera) can deserve it than eight megapixels than 12 megapixels by the Leica size color film for general consumers.

It is necessary to take the medium to use for the indication of the image into account.
For example, it may be said even with resolution to be able to start with a digital camera of the low-end enough if I display a photograph with the display of television and the computer that a thing of two megapixel degree is the mainstream to the utmost.
When I output it on a print of 4 X 6in, there is the difference that I can feel between digital and films even if limited.
If an output medium is for a big advertisement, a medium or the big seal which had high resolution will be necessary.
