That's OK - a stroll can be a few seconds, really. I don't know if Wouter would say that, but I believe our daily lives give us many opportunities, Andrew. The simplest everyday occurrences can be seen differently or in a very personal way that one can translate photographically. I'm sure you know this already. In reading one of your previous posts, I think you may have hit on one of the stumbling blocks..that you're experiencing. The desire to be doing something else, somewhere else can really be frustrating...and more. Since you can't (and I can say the same thing for myself because I'd rather be living in a rural area and am not), it makes you feel confined..or it makes me feel that way. Now that you've recognized this, I bet things will loosen up.
I think that your "Not Strictly Dog Walks" is an excellent example.
Even though you're the one who has started this thread, I can tell you that a great many people are probably finding it very helpful
Stroll photography... I love that idea. But for me as well even a few minutes stroll is a luxury.
Never underestimate the importance of bringing a camera to what seems like a "typical Outing". As we come into another New year, It's seeming pretty important to me right now.
