You need to be an adrenalin junkie when you travel with kids.

In the last year my wife has noticed me struggling to get downstairs on a Sunday morning. I've two young children and football has been so good to me over the years I don't want to spoil it.

I'd very much like to create my own style as a photographer, even if it's just for myself.

So it was a hard decision but I know it is the right one.

The first year I sold a photo to was a lady who thought I was a chef, for some reason. I've no idea why.

We spent a lot of time on the beach when I was young so I'd also take pictures of seaweed and crabs.

When you live by the sea, there are definite seasons when you can see the weather coming and going, which lends itself to photography.

Digital has obviously changed things a lot, but not all for the better as far as I'm concerned. Of course it's much more convenient and you're getting instant results, but to me it just lacks the finesse of a roll of film and it has a slightly superimposed feel.

From my point of view what I have to do now is appreciate and enjoy what football gave me, but now do something else with the same energy and enthusiasm I gave to football without expecting the same results.

I was pleased that two very disparate photographs, two images that each worked in their own way had appealed enough to other people for them to buy them. I was also relieved they weren't the last ones purchased, and that they sold for a pound more than the frame was worth.

I've had one very bad ankle injury but otherwise I've been incredibly lucky with my fitness. I've worked hard at it and I've always been fit even compared to other players. That sustains you through various parts of your career, but I am 36.

I've never put myself in the mindset that I'm actually any good at taking pictures, I just love to shoot things that catch my eye, whether it's landscapes or just my kids.

My wife Mariana is a good photographer too and, like me, she just picks up a camera and takes a picture when she sees something, rather than looking too deeply into it.

Sometimes I'll go by and there are a couple of swans, the next day it's a few ducks. I'd like to stop there every day for a year and capture how it changes, then put it all together to create an incredible image of a traditional English scene.

The problem for me is that I've never actually studied photography, so it's quite a steep learning curve. Cameras these days do so much for you automatically but I still think there's a point where you should actually know the technical side.

Training is such a vital part of preparation for a game, you really do train to play. It tops up your ability, like sharpening a carving knife. You can get away with not doing it for a while, as long as you have reached a certain standard of fitness.

What it all boils down to for me is having the enthusiasm to do something for enjoyment and being stimulated by what's around you. That's what photography does for me.

Why go now? That is the question people asked when I announced I was retiring. A combination of things made me feel it was all drawing to a natural end.
