#1οΌThis is the example of motion blur. To shoot a motion blur photo, we need to set up a slow shutter speed such as 1/30 to 1/100 while the object is fast moving.And if we close to the object, it will appear blurrier.
#2:This is the example of shallow depth of field. We need to zoom in to close to the object for getting focus on it. And there need some distance between the object and the background to make the background shadow.
#4: Both two photo are the center composition which helps stand clear as a portrait. For Matthew Jordan Smith’s, he used front light. Foe Timothy Greenfield-Saunders’s, he used the light between front and right side. I think they both used diffused light because there is no sharp shadow.
1. Good. Leaves in the wind is a good example though an even longer shutter speed would be more likely to result in motion blur.
2. Good. Also when you are shooting with a camera (as opposed to a cameraphone), aperture is an important contributor to depth of field.
I like that you used the same object for both photos showing how by changing your settings you can get very different results with the same subject matter.
3. good correction. You brought out the detail in the shadows.
4. ok. Yes the Smith photo uses front light and the Greenfield Saunders photo uses Rembrandt light which is as you say at a 45 degree angle. The directions asked for four points of comparison.
