Nikon D90 vs iPhone

Here's a picture of the same latte I took with my iPhone in my previous post.  I made the photo below with my Nikon D90 using a 35mm prime lens.  Since I had the aperture at 1.8 it created a shallow depth of field. Which photo do you like better?

Capturing motion

So yesterday morning I walked around DC taking pictures for my photography class.  The goal was to capture motion and to use shutter speed and aperture to compose my photographs.  I'm telling you this photography thing is not as easy at it seems.  Here's a couple of photos for your viewing pleasure.  Let me know what you think...I need feedback.

This one is from the ice rink near the Smithsonian -- it's a little overexposed. 

Tell you the truth I wasn't too happy with what I took on Saturday, so I pulled one I took in NYC over the summer.  It's post processed but the "blur" effect came from adjusting my shutter speed. 

Maybe it's because NYC is better city to photograph...that's for a different blog entry.
