photography and mathematics

[DrPizza]

A few math teachers on a listserv that I receive have been discussing projects linking together mathematics and photography.

1. Any ideas do you guys have?

Some of the ideas tossed about so far have included a graphical analysis of shapes inside a picture.

Another teacher has suggested calculating the maximum size a picture could be printed (based on the megapixels in the camera and the aspect ratio - leading to a quadratic equation.) Of course, that one is an oversimplification and ignores other factors.

What is this 'listerv' you speak of?

What age group are we aiming at here, back on topic?

Listserv, afaik, is just a specific email you send to and it forwards it to everyone on its special list. Ie: my class on heat transfer has a list serv. Instead of emailing everyone in the class the professor emails 12399djhhd@uci.edu and it automatically knows who is in the class and emails all the students registered for that class during that quarter of that year. Of course since they can be abused easy they can also be restricted to foreward email only from specific users

I don't know about max size a picture should be printed...I'd probably go for graphical analysis - or perhaps (maybe for a more math inclined group?) some work on focal lengths?

the megapixel thing is going to produce odd results because different cameras perform differently at the same megapixel AND there are variations dependant on the photo subject ANNNNNNND the size/quality ratio is more of a personal preference than a set value.
Look at all the people that have noisy photos but "don't see the noise"

I would do something with light and aperture and shutter speed
maybe figure out the equation to calculate speed of an object by using the length of the motion blur and shutter speed

High school age group - algebra through calculus.

Hey, I like the idea of the shutter speed/speed of the object
