In reference at ativan dose lethal decisive moment, attributed concept to Henry Cartier-Bresson, photographer Pedro Meyer distinguishes the digital moment, to enunciate the qualities of the photographic work digital contemporary, root ativan dose lethal gives foot us distinguishing the stages of the work of digital photographic production.

First, it is necessary to clarify the moments that it undergoes the digital visual sign, and in broad strokes we found two:

1. Technological moment: election of technical variables, sofware and hardware.
2. Discursivo moment: ativan drug information of discursivas variables, subject, sort, values, styles, ativan drug information treatment, etc.

Traditionally the production of the analogical photographic sign has occurred in three times:

1. ativan dose lethal : ativan drug information the firing or it takes.
2. Photographic: during the firing or it takes.
3. Postfotográfico: after the firing or it takes.

At the moment, the production ativan dose lethal the digital photographic sign, occurs in three times:

1. Predigital: before the digitalzación of the light, of variables for the conversion or use capture analogical of the analogical thing to the digitalis.
2. Digitalis: elaboration of the image with properly digital elements: scanner, digital copy, use of software (programs of treatment and production of digital images); and during the taking (the ativan dose lethal firing tends to the disuse) or it captures (like ativan dose lethal term more) digital. The digitalization or virtualización is a species of second digital stopper, where analogical and the light is registered in numerical terms and of electromagnetic nature.
3. ativan dose lethal : treatment of the digital capture with specialized programs; the postdigital stage allows to give back the digital sign the analogical thing, to the image as it treads printed.

I. ativan drug information the analogical photographic production of the visual sign:

1. The spatio-temporal matrix always referential, indical or will be indexed, in two slopes

a. Matrix of necessity: territorial space/cyclical time, (mainly in the prephotographic and photographic stage), and;
b. Matrix of possibility: abstract space/linear time.

2. The ativan dose lethal always will be an image turned into ativan dose lethal track and tangible analogical matrix, an analogical sign.
3. The relation with the analogical visual sign always will be of indical reference (material) and physical proximity.
4. The analogical sign does not acquire the interactive quality.
5. The decisive moment, the moment ativan dose lethal the firing and its result, ativan dose lethal is the turned moment in analogical track, and in he is aporía of the fixed moment or congealed moment, always of physical referential necessity, it is ativan dose lethal that reason a indical moment.
6. The ativan dose lethal is the fundamental ingredient of the analogical ativan dose lethal image.
7. The photographic act is another element sine qua non of the analogical photography, that includes the action of the firing of the photographer, plus the use of the photographic device, the camera.
8. The discursivo and expressive treatment of the analogical photographic sign is limited by the technological variables of the traditional photography: film ativan drug information support, format, b/n, color, negative, transparency), ativan drug information camera, diaphragm, speed of clogging, light (temperature, reflection, diffraction, direction, contrast, diffuse, direct, indirect, natural, artificial, flash/synchronization), optics ativan dose lethal great angular, telephoto), movement, two-dimensionality, latent image.
9. The element of visual expression as minimum unit is the grain. ativan drug information unit product of the photosensitive emulsion of silver halogenides. PU that to the taken part being is destroyed.
10. The analogical image is not a ativan dose lethal sign, since its existence depends on a materiality or hardware, although yes presents/displays the quality of being reproducible, any alteration in the support is definitive.

II. In the digital photographic production of the visual sign:

1. The spatio-temporal matrix not always will be referential or indical, only at ativan dose lethal time of the ativan dose lethal capture of the image, that is to say, in the predigital stage. In the other two ativan overnight the sign loses its indical ativan overnight to become sign without analogical ativan dose lethal ativan dose lethal in the postdigital stage, the digital sign can recover its statute of track. Therefore, the digital visual sign participates in the following spatio-temporal matrices at the time of its production:

i. Matrix of necessity: territorial space/cyclical time, (mainly in the predigital and postdigital stage), and;
II. Matrix of possibility: abstract space/linear time.
III. Matrix of impossibility: in the digital stage, it is possible to construct images with purely digital visual elements without track, that is to say, already digitized.
IV. Matrix of contingency: space site/time moment, the digital visual sign is updated at the moment at which it ignites and it is articulated by a program and a user.

2. The result always will be an image without not necessarily bidimensional and tangible, but virtual, that is to say, actualizable track analogical, by a program.
3. The relation with the digital visual sign not always will be ativan overnight indical reference and physical proximity, can be a relation numerical, not necessarily iconic, symbolic, intangible. It is possible to describe, to construct and to reconstruct a digital photographic image, of exclusively numerical way. I could be established an ativan overnight with the digital image by means of audio sound//palabra/o tact. The Pouray program, allows to construct an image with words.
4. The digital visual sign acquires the quality and the interactive possibility.
5. ativan dose lethal digital moment is the turned moment in electromagnetic ativan dose lethal and in it is inserted in the possibility of the ativan dose lethal dynamic moment and in transit, he is subject to the abolition of the fixed moment ativan dose lethal the real time, by the continuous moment. And no longer it participates in a indical moment but in a virtual moment.
6. The light is not the fundamental digital ingredient, ativan dose lethal the electricity, that is to say, the light turned into electrical impulses with possibility of being recorded numerically and magnetically.
7. The photographic act that ativan overnight the action of the firing of the photographer, no longer is a fundamental factor, the digital photographic act eliminates the territorial necessity of the firing or captures of the image, it includes although it. Now the digital photographic act can be given with other devices that are ativan drug information the camera, that strictly disappears like even necessary artifice the photo, replaced by endorsements of capture CCD (device of load connection, a multi-layer silicon chip).
8. The digital discursivo treatment crosses all the established keys ativan drug information rhetorical canons, as well as the functions, uses ativan dose lethal applications that give statute him as legalized visual sign ativan drug information the traditional culture. Nevertheless, the digital visual sign experiments just as other expressive and discursivos supports, an increasing questioning like statute really, as certainty sign and participates in the effect that we denominated fading of the ativan dose lethal where finds other uses, other functions, other needs, and another form to use it and to be related to him.
9. ativan dose lethal digital image releases to ativan overnight photographer of the commitment with the testimonial reality, with the referential ativan dose lethal indical and it condemns to the ativan dose lethal the uncertainty it gives back or it to the epistemologic territory of the faith on the image.
10. The discursivo ativan dose lethal expressive treatment of the digital visual ativan dose lethal is limited by the technological variables of the digital photography: capture device ativan drug information resolution, format of the digital endorsement,), support, b/n, color, ativan drug information transparency), diaphragm, speed of clogging, light (temperature, reflection, diffraction, direction, contrast, diffuse, direct, indirect, natural, artificial, flash/synchronization), optics (estenopo, great angular, telephoto), movement, ativan dose lethal latent image.
11. The digital sign depends besides ativan dose lethal variables of the digital camera, ativan drug information of the variables of the program (software) of treatment of images. Photoshop dominates the rhetoric of the digital treatment at the moment, although new programs like Gymp arise, ativan dose lethal gratuitous versions that begin to be competition. The technological dependencies of the digital image therefore occur in three great sectors: digital camera, programs (software) of treatment and programs/more hardware of ativan dose lethal and impression.
12. The ativan dose lethal of visual expression as minimum unit is the pixel. Susceptible unit that to the taken part being can be reversible, when modifying becomes it, is not destroyed.
13. The digital visual sign can be clonar and be combined with other visual elements.
14. The digital visual sign admits to include animation in the same.
15. The digital ativan dose lethal allows to eliminate parts of ativan dose lethal image, to modify the color and the texture, to make bottoms, to generate images purely digital.
16. The digital visual sign allows to see and to send the images right away.
17. The ativan drug information image in the structure of Internet ativan drug information to make arrive the image at ativan dose lethal people, extend the diffusion field and multiply the image in an infinite number of copies.
18. The ativan dose lethal image does not destroy when ativan dose lethal screen goes out, the virtual being and to own the clónica quality, its survival grows exponentially.

The digital moment no longer ativan dose lethal given strictly in a single time, happens thus through the decisive moments of the traditional photography, the capture of the image, plus the properly digital moments that are in favor conditional of the electronicses camera-digitalis, computer (computer), software captures, treatment, diffusion, normalization, scanner, impression hardware, plus the continuous moment that allows to Internet, that is to say the call real time.

The digital moment also happens through a planning different from the image not only already like technological product, but like cultural object, that is in favor conditional of its potentiality and interactive capacity. The digital image as cultural ativan dose lethal also happens to comprise of ativan dose lethal by Internet, as well as by the one of the new uses that such images ativan dose lethal to make to the user and political institutions. The contingency to which it responds the digital image in Internet, makes proliferate the creation of images with marked sociological sense, that is to say, like reflection of dominant the discursivas and rhetorical tendencies, at this moment, pornography, monitoring, entertainment-leisure.

As we see the digital visual sign is more complex than the analogical one. It involves more variables and he is more dynamic as much in his transit or spatio-temporal circulation like in his possibilities of treatment, intervention and forms to be ativan overnight to other signs, programs and users. ativan overnight emphasize three main qualities of the digital photographic image: intertextuality, interactivity and potentiality, ativan dose lethal radically distinguishes that it of the ativan dose lethal sign photographic, that can be intertextual, but interactive or never virtual.

Immediately a comparative table of of characteristics between the digital photographic image and the analogical one:
