Aperture: New photography software from Apple
If you work with photography and wants to achieve professional results with a normal equipment, you should consider Aperture. Aperture is a new software from Apple that allows photographers (professional or not) to take full control of their creations.
By allowing access to the original formats of the pictures (instead of working only with jpeg or related formats), Aperture gives full control of features such as color, luminescence, focus, and other features that can be modified by software.
Aperture offers everything that professional photography packages provide, but it is very easy to use, in the full tradition of Apple Macintosh software. It also sell for much less than normal packages for photography, so I think that Aperture is a gift from Apple to the photography community. It is an essential part of the "tools of the trade".
