our course work was to pick a photography do an artist research sheet....responce to that photographer sheet and some other things i cant really remember but then the final peice which was the examSat Jan 14, 2012 4:22:47 pm

what do you mean
Something like:
What is an "f number" and why is it important?

You are not stupid you just have not learned everything yet. On a camera the aperture (*size of the opening of the lens) is what determines the amount of light that is going to get into the exposure. The size of the opening is your 'f' number.
im really dumb beacuse i have no clue
I will try to explain it the way I understand the 'f' number.
I have been told to think of photography as both an art and a science becoming one.
The 'f' number is like a setting on a camera to help determine the amount of ight that gets to the exposure. The smaller the 'f' number the less light is let in. Each f stop on a camera (as far as I understand it they are the same no matter what camera you use) lets in half as much light as the one before it. It can be thought of as a ratio.
The lower the 'f' number the focus will be on your subject and back and foreground will be less in focus.
The higher the 'f' number would result in the opposite.
In my opinion, you are learning the love of photography now. Later you will learn the tech side of it. (or if you are like me just listen to what really techy people say about it and follow as much as I can before i wander off and take more pictures without truly understanding what is happening but enjoying myself all the same.)
Try not to be so hard on yourself.
Have a great weekend, girl.
Hugs.

If my defintion/explanation down there is wrong please correct me. Or if you have an easier way of explaining please do.What is an "f number" and why is it important?

Your explanation is incomplete. The f number is a ratio of focal length divided by the diameter of the opening through which light passes. This affects both the percentage of available light that enters and the depth of field, but it is not the sole determinant of either. The amount of light that enters is also determined by the shutter speed and the reflectivity/opacity of the lens elements and filters. In addition to aperture, depth of field is also determined by focal length, distance from the subject, relative distance of foreground and background, and size of the sensor or film.

The f-number is the focal length divided by the "effective" aperture diameter. It's a dimensionless number that quantitatively measures lens speed. Expressed as f/D where f = the focal length and D is the diametre of the focal pupil. "f/" followed by a number is treated as a single symbol (eg: if the focal length is 16 times the pupil diameter, the f-number is f/16). The greater the f-number, the less light reaches the the film or sensor. The lower the f/number, the higher the possible shutter speed. I think.im really dumb beacuse i have no clue

The part about the f number being the same regardless of camera is somewhat misleading, although it's technically true. The calculations is done the same way, but the consequence is not necessarily the same due to differences in sensor size and flange distance. Also, the same f number on a different lens doesn't necessarily mean the same amount of light will be allowed to enter, because there are different types of glass and coatings.I will try to explain it the way I understand the 'f' number.

Thanks for correcting/clarifying.
Your mind amazes and facinates me.

I am just more precise than most people. The extra details were probably never explained to you. They are often omitted as not necessary to discuss because they are special cases.Sun Jan 15, 2012 2:21:57 am

More than likely you are right. Or the person might have realized I was way over my head in details already and had pity on me.
