I took a walk with my kids through the town I grew up in. I just took some snapshots of whatever caught my eye. I used a 300mm lens most of the time to get the shallow depth of field, and get up close to things that are a bit out there. I was using a DX camera (crop sensor) which means the effective zoom was 450mm equivalent. Of course the optical properties are going to be that of a 300mm lens, namely depth of field and compression of space. Longer lenses have more shallow depth of field, blurring out the background. They also compress space, making it look as though things are closer together. Wide angle lenses exaggerate space, making things look farther apart.
I captured images of birds, a local barber shop (the traditional kind, don't see too many of those anymore), and of course, two of my kids. I was really happy with the picture of my kids running to the park. The color saturation in the image was really nice and I liked the composition. Not to mention I got them both on the same step.
