I mention to my students all the time that they need to make choices as to the type of photo they want to make--and the type of photo that is plausible to make. Exposure is key. How can we expose pictures correctly and accomplish what we want to. During Craig Walker's talk to my class the day after his lecture, I was making some pictures, but the room was dark so we could view the slides. I chose to make an image of Craig's photo and silhouette one of my students within it. It was the only way to expose this correctly without bringing in lighting. I had to make a choice. In learning photography we all have gone thru seeing great pictures and being befuddled by them not turning out as we see them. As we learn how the materials and cameras work, we begin to realize what we can make with them. We actually begin to see the world the way our cameras and film are capable of recording it. Ultimately we, as journalists, want to record the world as we see it, but we do have to do this within the confines of technical possibility. So sometimes we use devices such as silhouette to accomplish what we see and want to project in order to tell the story. Its a matter of seeing the picture and knowing the limitations of the materials and devices----and this takes time and practice to learn. P
