Photo
 

How is the value of photography.

In my opinion, firstly, determine the value of the photos the same criteria as in the painting /graphic:
  author name (its significance), artistic and aesthetic value, the year /period of creation, size, state of the snapshot.
In addition to aesthetics can determine its value the moment itself portrayed: an important historical event, person, or His Majesty the moment, seized the photographer.
It is important to time-stamp is made it is valuable, if made within the period of the snapshot.
And your personal attitude to the picture.
(if it is a photograph of your grandparents or a beautiful young mother, she is priceless:))
This is in general.
I think the experts are correct me or add to it.

in general, it is all so, I agree with Gala, but explain why then are so many photos Gursky??

Everything depends on the image. Based on many factors: the figure, or film, what kind of printing was used, and when printed, and when he made the frame (during a frame and print image can be different), also considered himself whether by printed or not, is the author's signature on photos, etc..
With regard to the artistic image is taken into account composition, style, work with light, appropriateness (reportage photography, subject photography, portrait photography, music, military, without thinking now, I can not remember).

:) Yes you are, Meister, this is for me is the same riddle, as well as some pricing in the painting, it is to specialists ..

While writing you have already answered)) in principle, all true)

These experts explained to me, as usual, great conceptualization reflects the era of the twentieth century, the expression in the photographs of all the advantages and disadvantages of the twentieth century. Even on this forum somewhere discussing Gursky photograph "99 cents", sold for 3 million and then the main argument of supporters was - the image of consumer society, the type to which we come ...

But if contemporary art is the Hurst, then why in the photos are not to be Gursky?

The very work I like, visually perceived wonderful painting such things, and laden with meaning, but the price is for me remains a mystery , whatever said ...

but I like it and apparently did not like ... for me in photography is important, above all, time, beautiful, fascinating, unusual ... When the picture frame imprinting is rarely detectable in life. These pictures are interesting for me ... but this ... alas ...

Here are a couple, shook ... yet there are many
