Texture-the feel, appearance, or consistency of a surface or a substance.
I believe that texture is one of the hardest things to capture in a photograph. Reason being, texture is how something feel, you need to touch the object to really know. In a photograph we rely on out past experiences to assume what the texture is. For example a picture of mashed potatoes with gravy and a type of meat depending on what you experience with food is when it comes to that type of dish you already have your assumption on the texture of the dish, but that is all depends on how it is presented to you. If you have never had the experience of interacting with the object or know of the object you can’t accurately know the texture.
You can tell when gravy is cold if it clumps up and looks unattractive the mash Potatoes could be lumpy but just look soft and unless the meat is cut open you can’t tell if it was cooked to rare which would be soft and still feel raw or well done which is firm and a somewhat dry depending on how well done the meat is. In order to portray texture a great amount of detail needs to be put in the photograph, so the viewer has an idea of what it feels like.
Lastly photographer’s cheese cake was made from the egg yolks left after photographers had used the egg whites in the chemical process of taking a photo.
