Hipstamatic is a popular photography app for the iPhone, although probably not as popular as it once was. I think I may have mentioned it previously as every so often I delve into it to see what I can do.
Briefly it allows you to use filters on photographs taken with your phone as well as adjust settings, such as exposure, saturation etc. Some filters are overly dramatic but exercising some restraint can yield impressive results. By curbing your temptation to go completely over the top some striking images can be produced. I tend to tone down the filters and then perhaps adjust saturation, highlights and shadows to get where I want.
