Does photography speak a universal language that does not need translation?

Often...in large proportion but not at all.

Photography indeed speaks different languages (or universal language). The beauty of it is that it is open to interpretation. Humans perceive reality (or our assumptions of reality) differently leading to different perspectives on what constitute a solid knowledge (or one interpretation) of a picture. In fact,  it shouldn't be translated and limited, instead, keep it open for interpretations. On the other hand,  Combined with marketing communication, it is a different story! Marketers rely heavily on photography to creatively communicate a message. In this scenario, I do belive that translation is needed due to cultural difrancases and to avoid negative associations with the brand. 

Photography capture human behavior and emphasize the personality who you are

Depend upon photographer. I am fully agree that a best photographer click have a universal language

YES BUT THEN PHOTOGRAPHY IS REAL NO EDITED BY SOMEONE

Photography that has no letters or any literature sign could be the one with universal speaking language

Yes it does. Photography means art. The artistry of the photographer shows in his photos. It may have different perception from the viewer but for artists, its magic.

yes a warm smile is the universal language of kindness.

Photography speaks an international language that could be understood by everyone. However, in the business world the interpretation of the photography could send different message depending on the the external or internal environment of the organisations. But it should be recognised that they are some pictures that have a universal acceptable interpretation. 

no, some people they cannot understand the english so that they need translation also.

a picture have 1000 meanings that described many types of meanings inside and no need to translate the meaning to the language.
