What are silver salt photos, how do they compare to current photos and what are the benefits?

Non-professional, just a player, don't take me lightly.

Silver salt photos? Are you talking about silver salt negatives or silver salt photo paper? Both are only black and white play oh.

From the point of view of the negative, black and white is basically the world of silver salt, there was a history of being the share of the dye negative, but in the digital era, that kind of first goal is low cost, high efficiency has been basically eliminated. Silver salt has an unshakeable position in the pursuit of high-quality photography in the crowd due to its great latitude, far better gray scale than dye, can control their own processing, unique graininess.

Said silver salt photo paper, in fact, should be said to be barium-based photo paper. Through the optical enlarger will be the negative image to the paper and through the process of film similar to the negative development and finalization of the formation of photographs. Its relative to the dye printing has similar silver salt negative relative to the advantages of the dye negative, and its operation can be excellent scheduling, can not be completed through the computer HDR. the most important point, each one is not the same, and than the preservation of the finished product of the printing of a lot of a lot of a lot of long, generally low-quality printing in one or two years on the fading into the white, the good printing in the absence of light conditions can be preserved for about 30 years, the best can be more than 50 years. And barium-based photo paper as long as the deacidification process properly, ordinary photo paper can have a 20-year start life, a little better than 50 years easily, save more than a hundred years of a lot of (relative to the total number of photographs of that era), up to now the longest preservation time seems to be 160 + years, can not remember, and this preservation period as long as it is not a strong light exposure is not how to avoid light.

In fact, simply put, the average person playing with silver salts, the biggest fun is not how good the quality of the photos is, but the process itself is very fun.
