I don't know what you mean exactly, but I'll try to tell you what I think you want to know The lens is a Sigma f 1.4, 30 mm , and yes, it is a magnificent lens. The depth of field, angle and composition are exactly as they were taken originally. But I almost always use some type of cross-processing when editing my pictures, which causes subtle color contrasts that give them a certain look and feel. Of course I also tweak colors, contrast and such by hand, as well as some patching of the skin where needed. The amount and type of work I do while post-processing depends on the original picture. The better the original, the less work is needed. To give you an idea, this picture needed very little.
