I am also going to bring my three lenses to class to show them to show what an aperture looks like too.

What about getting an old, non-working or valueless lens and slicing it in half as a visual aid?

| Holy cow. 5 min. for The Lens to a group of people who've probably never given that much thought to The Light. If it was gonna be me doing the presenting I think I would skip the technicals & concentrate on Light. Bring a fresnel lens & a magnifying glass for show'n'tell. The simplest feature of any lens is how it gathers & focuses light (& why you would want to do that). JMO. |

Or just not letting them handle any of your good lenses.. That's a good bad way to let your classmates spend your money.. |

Slide 1. Show how much bigger it is than that other guy's
Slide 2. Talk about the flames you painted on the lens hood
Slide 3. Discuss how it could be mistaken for an AK-47 or RPG
Slide 4. Photos of you juggling 3 of your lenses
Slide 5. Photo of the reason never to juggle your lenses
End with an off-color joke. |

I have a question that is getting more and more difficult for me to figure out...
Here is my dilemma. In my photography class I am having to do a presentation on the "lens" and being that is such a broad subject, how am I supposed to do a 5-10 minute presentation on it and cover the main things?
I am thinking of narrowing my presentation to 5 informative power point slides (1 minute per slide) then of course my title slide and "the end" slide which will add on 30 seconds or so. Doing this would give me about 4 minutes of overtime that I could play with on any slide I want to cover more in depth.
What do you think I should cover on each slide? I am not asking you to do the research for me, in fact I would like to do the research myself. I am just asking for something like this...
1st slide - "subject"
2nd slide - "subject"
3rd slide - "subject"
4th slide - "subject"
5th slide - "subject" |
actually, one slide per minute is a lot of time per slide if they're not interested. I'd use more slides and show examples. Take a picture of the same subject using 10mm, 50mm, 100mm, 200mm, 400m, etc, and show a series of slides on what focal length does
Show a series of slides with different aperatures 1.2, 1.8, 4.5, etc out to 32 to show what aperture settings do for depth of field.
Take a picture of a moving subject with 3 different shutter speeds -- fast, medium and slow
Just talking about the different issues on the lens doesn't teach it as well as if you show them the results. You can have your slide up for 30 seconds to roughly explain your concept, but then show 5 or so pictures for each concept -- 3-5 seconds each. A picture's worth a 1000000000 words!

I have a powerpoint presentation on that very subject that I put together for our local camera club, that you can have if you want.
My main topic was DOF, what is it, what affects it and why.
I cover the origin of the Lens, ie where the word Lens comes from etc
How light passes through a lens and why, ie refraction and why light refrects
Focal distance
Focus, what do we mean by it and what is in and out of focus (ie circle of confusion)
Aperture, what is it why does it do what it does
I also touch on hyperfocal distance
It's all basic diagrams that I drew myself in PP so nothing earth shattering but you are welcome to it.
It's around 15MB
I think I yaked on for about an hour but you could cover it in less time if your audience is on the ball :)

| I would suggest adding an explanation of hyperfocal distance to the presentation. |

So this is what I am thinking I will do...
1st slide - aperture and its relation to light
2nd slide - focusing infinite to its closest
3rd slide - mechanics (like focusing ring, aperture ring, zoom, etc)
4th slide - Zoom lens vs fixed and also wide vs telephoto.
5th slide - Fun lenses such as lensbaby or fisheye.

I wonder why nobody ever mentioned tilt/shift lenses. Think of miniaturized scenes, everybody loves them (except when I enter it in a challenge)
Feel free to use this as an example.
ETA: If it is possible in your situation, add a 6th slide with a quiz; show some photos and let them guess with what kind of lens / what aperture they were taken
