As a student working towards a doctorate level degree, I find I know nothing about cameras and how to take a “proper” picture.I found this interactive site on a web search for “introductory photography.”There were two different aspects that the interactive site delved into; the first part being depth of field and the second part being exposure.I know absolutely nothing about cameras, and was immediately intrigued on these two aspects.Had there been a list of a hundred different camera scenarios I would have been intimidated and overwhelmed.Instead, these two basic principles focus on allowing the subject to grasp an understanding of how each one works and not on gaining a perfect picture and are simple and easy to use.
The depth of field uses two variables: Focal length and F-stop.I didn’t know what either one meant, and wished that they had been clearly defined on the site. However, it only took a couple seconds of ‘messing’ around to determine what they were.Focal point ends up being the main subject of your picture and the F-stop allows you to change how much of the background you want in your photo.A larger F stop means more background is in focus in the picture and vice versa for a smaller F stop.
The second photography aspect taken into play was exposure using shutter speed and F stop.Once again, I have no idea how to manipulate light exposure on a camera to get the optimal photo, or what shutter speed means.However, by once again using trial and error, it enables the user to learn what he or she wrong or right, instead of just being given the correct answer, you can determine which works best.Turns out, that as the user increases the shutter speed, the more in focus the camera is.F stop is not important as the shutter speed is in the camera.If the user sets the shutter speed to low, then too much light is let in on the photo and the picture is blurred.
My one complaint would be that an explanation of how shutter speed/ F-stop/ Focus all work.I understand each role and I’m sure other students can determine what their job is, but a more in-depth description of how it works would be neat.
