In order to take a photo like this, I must get low.... really low. I get so low that I'm lying on my stomach at 7:30 in the morning in my pajamas with footies... not really. I do get all the morning dew on my clothes though but its worth it. I have pretty good eye sight so I can spot the little dew drops on the blades of grass. It takes a lot of messing around with depth of field and how far I am from the subject. I can take up to 100 photos of one square foot area and have a few really good photos from that.
I will suggest for any beginner photographers that are looking for an easy way to get interesting photos is to buy a macro lens and just explore your yard or the park. You can make the tiny world of bugs and plants fascinating.
