Who is it?
Pick up the nearest paper. Have a look at the sports pages. Who is in the picture? I bet the first thing you did was look at the caption.
That caption has to come from you.
You may have the best image in the world but if you or the picture editor does not know who is in the image or where it was taken it may well be worthless.
Make life as easy as possible for your clients. When on deadline they are not going to call you to see who is in the frame. And anyway if you knew you would have captioned the image.
Anyway one day by chance they call to see who is in the picture. You don’t know and say you will get back to them and put the phone down. In the meantime a guy desperate to get his name in the paper sends them an average image from the same event. It is captioned, it is the right action and it’s free.
Sorry but you lose out!
He is a happy chappy and it cost you your freelance fee because you did not spend 2 minutes captioning the image.
