FOR THE PAST NINE MONTHS I have been engaged in a photography project, documenting intercollegiate athletes at practice. Practice is what athletes mostly do. A starter on the football team may be on the field for 24 minutes of playing time; those minutes will have been preceded by 10 or 12 hours of practice, at least. Swimmers work out for two hours twice a day, five or six days a week; a sprinter's event may be over in two minutes. I shot every Johns Hopkins University varsity sport, football and field hockey and wrestling and fencing and lacrosse and more, making something like 15,000 images. The best will be published in Johns Hopkins Magazine next September. Here is one image from the project, taken in the varsity weight room. The young man is a football player.
