Where to go to see the math of photography?


Recommended Posts

The math I dont use it. I guess or estimate / guestimate.

 

F 2 you would need a faster shutter speed f 11 slower shutter speed.

I have seen a simple chart that shows the matching numbers.

 

For me setting aperture to get depth of field is estimating and knowing what you what the photo to look like. I dont pull a chart out.

 

If your outside that can change fast like on a partly cloudy day the intensity of light change quick and you will change change the shutter speed settings so when adjusting aperture for DOF keep an eye on the meter. The numbers dont have to be set exactly to what a chart shows if you capture all the detail you can edit it with software.

You don't make an image with a calculator. You need an imagination, a good eyes, and some good sense

for art and composition. You ned to observe and use the depth of field button on your camera, and a lots

of experience. If you want to create a good image, by using all kinda charts and technical gadgets, you

never going to create a good image. You never use rules, except a few basic rules, but even theta, has many exceptions. Nobody can give you a chart, how to ride a bicycle, you have to learn the feeling of it.

And a very basic. Every beginner, supposedly has to learn the technical now how, by starting to shoot in

total manual mode. If you never learn al those aperture - shutter speed - depth of field- ISO, interactions,

you in the later time my produce a good image , but you are going to use your camera, like a point and

shoot camera, and you going to be a "point a shoot photographer".

To be a good race driver, you have to learn first, how the engin-gerbox-cluch-brake-stereing works,

before you learn to drive the car. Some European countries, you do not get a drivers license, if first, you do

not known the basic, ho the engin-gearbox-cluch works.

No such a thing, as "math of photography"!

Try this . . . The smaller your aperature value (2.8, 5.6 and etc....) the "smaller" your depth of field. The larger the setting, the "larger" the depth of field.

 

Try changing your setting - while using your metering mode - and you'll soon get the hang of it. Obviously exposure time has alot to do with it.

 

Forget the math! Take a look at the math at the wikipedia link above and tell me you can use that while taking a picture. Bela Molnar is correct - - - just take pictures and experiment.

 

PLAY with your camera.

 

peace out
