A photo is a great way of saving important moments. In addition, it is a wonderful medium for forwarding information of a situation or, for example, a product you are hoping to sell.
Everyone has a camera of sorts but taking a photo is much more than tools. In addition to the moment a photographer has to think about how to crop the image and how the target is lighted – just to name a few variables.
In addition to taking photos I do manipulation in Photoshop.
