1. Digital Photography School


Welcome to Digital Photography School – a website with simple tips to help digital camera owners get the most out of their cameras.

My name is Darren Rowse and I’m the guy behind Digital Photography School. I’m a digital photography enthusiast and while it’s not how I make my living (although I do pick up a few paying jobs) – I’m the guy in my friendship group and family that always seems to photograph the special occasions. I’m still learning and improving my photography but like to share what I’ve learned so far.

I previously owned and operated a digital camera review site – and over the two years of that site I had a lot of emails from readers asking for tips on how to use their cameras and came to the conclusion that while there are many millions of digital cameras being bought each year around the world that a very large proportion of those that buy them could be using them to achieve better results.

At my previous site I’d written a number of ‘tips’ articles over the past couple of years but it has largely been a site focused upon cameras. As a result I wanted to start a site dedicated purely with ‘how to’ tips.

And Digital Photography School was born.
