A camera, you and a subject. That's all you need to get great looking images on anything.
1. Get down
Get down level with your subject, whether it’s a camera, spider, child, product etc. Get some distance between the subject and the background. In the image below I shot down at the camera, the foliage is too well-defined around and behind the subject, I actually want it to blur.
2. Zoom in
The longer focal length the better – 50mm and longer is great. 85mm and longer is awesome. This works up to a point, so I wouldn’t go beyond 200mm unless you’re going for a very specific flat look that calls for it.
3. Shoot wide-open
Use wide apertures – 1.4, 1.8m 2.8 etc. This will cause shallow depth of field and cause the background (and foreground) to go blurry, placing more emphasis on your subject.
