The World of Deaf Culture (Part 1)

This is another series of videos, I believe 4 of them this time... The one here is really good...

Final Question and Math

How long does it take for an EXPO marker to hit ground from waist height? And what shutter speed would be needed? 

Finding the Formula 

Potential Energy (PE) = Kinetic Energy (KE) 

PE=mgh 

KE=1/2m*v^2

In this case 

*m=mass

*g=acceleration due to gravity (constant of 9.8 m/s^2)

*h=height 

*v=velocity (velocity=height/time)

Simplified! 

PE=KE

mgh=1/2m*v^2

2(mgh)=v^2

Square root of (2(mgh))=v

V=d/t BUT we want to find time, so t=d/v

Final Formula: T=d/(square root(2(mgh)))

d=floor to waist height 

d or h = 0.99 m

m = 13.3 g

g = 9.8

Time = .99/(square root(2(13.3*9.8*.99)=0.0616

Into a fraction: 0.0616=77/1250

Closest shutter speed! 1/15

Last Strobe

The other day Audrey and I just wanted a break day so we tried to do something different for a strobe. So this is Audrey climbing stairs!

Shattered Lens.

For my homemade device, I decided to do something different. I had thought about making my own vignette, but that didn't work out. So I chose to smash one of my lens filters. I thought that it would smash nicely and then I could hot glue it back together to take pictures for this. But I forget that glass smashes in a completely different way. Pretty much destroyed at a point and then "rays" out from there. And that's what it did. When I stated taking pictures of things in my backyard, it didn't really get the look I was going for in the photos. They were just fuzzy, it looked like it was humid. And then the thought hit me, the center of the smash was right there. So I tried taking a picture with the sun peeking through a tree. This look was cool, the light spread out all over.

*No worries, I do have more than one of these filters(:

Building Blocks to Homemade Device

The first of these is with smoke and a laser.. And the other two with a laser. (:

Strobe::Broom

We decided to try this one a while back and it's actually sweeping a broom. (:

Scootering Through the Dark::Strobes

The second and third images on here are what we actually started with getting... Where we could see the scooter and the hands, but we couldn't see any of the body. The first image has a hidden face. (: And the fourth image kinda turned out. We could see the majority of what was happening.
