I've been doing some close range photography with a copy stand. I look at my pictures, and they are never as sharp as I would like them to be. I use the timer and decent lighting, but some sections of the image aren't as sharp and detailed as others. I use the photocopy option in GIMP, and that begins to make things a lot better with some digital sharpness added in. However, I'm still trying to understand what makes a picture sharp. I was searching through this forum, and some people said using a macro lens can increase picture sharpness. How so? Does using the macro option on a camera increase sharpness? I'd say I'm taking pictures about 24 inches away from the object. What are the best ways to increase sharpness? Is it the lens?
