Photography is an evolving Art form. Fashion, Product, Advertising Photography, as every genre itself  has transformed too. The way Photography has changed a lot to what it was and what it is now. Commercial Photography’s meaning and representation has changed in a way that the image represents something that sometimes is not realistic, Photography as an illusion. Photography has changed in the way we look at it know, it has changed gender issues, sexuality, ethnicity and the way the body has been portrayed or any product. So when looking at an image you have a lot to think about if you want to fully understand the concept of it's meaning. It’ not how it used to be, women/men in clothes, showing of the designers creations. But it has a hidden agenda, hidden word, a meaning that it is try to communicate to the viewers. The words in the image, the image are the words, words are hidden in the image or the image is the word are many ways of explaining how an image are seen and understood in today's photography. 
A  photograph is not just there for you to look at and like or dislike and pass it through your memory. But it’s there to give you a storyline, a desire, an illusion and a fantasy. The image makes you want to buy what is being advertised to you.
