I think a model should know how to adjust photos, turn a Cd of images into printable jpgs, and know how to resize an image.
I discovered tonight a website called Picnik.com. Maybe you have heard of it?
It is something a model should know about. Especially if you are aspiring and might need to crop a photo.
This is a free service similar to Photoshop but if you can not afford the program this is a free alternative.
Check it out. Bring your photos to this picnik.
