What I've been up to!

This is a photo session I did two weeks ago.I had so much fun with these two, they asked to do a photo session just because they wanted to have some fun! What a cute young couple! Hope you guys enjoy.

I used many different lighting methods

















Lighting Extended: Inverse-Square Law

The Inverse-Square Law


In technical terms, an inverse-square law is defined as “any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.” With a definition like that, you’re probably wondering what on earth this could possibly have to do with photography (and no one could blame you). Inverse-square laws apply to many, many things in the world. Today however, we’re only going to be looking at one of them: light.


For those of us without an intense knowledge of advanced mathematics (or even very basic mathematics for that matter) something such as the inverse-square law can seem incredibly daunting. 

The law itself, in photography, applies to lighting. It applies to any sort of lighting really but its most relevant application is with off camera lighting. In a nutshell, the inverse-square law teaches us how light works over distance and why the distance between your light source and your subject is so important.


Let’s say we have a light source which is on full power and our subject is 1 meter away it. If we move our subject double the distance away from the light (2 meters), how much of the light’s power will reach it? The natural reaction is to think “half power” – but unfortunately that’s now how light works, it follows an inverse-square law.

According to the law, the power of the light will be inversely proportional to the square of the distance. So if we take a distance of 2 and square it, we get 4, the inverse of which would be 1/4 or rather, a quarter of the original power – not half.

Moving our subject 3 meters from the light (3 * 3 = 9, so 1/9) the power of our light source now becomes 1/9th of what it originally was.

Rachel's photo class assignment 2



My beautiful mother and sister on a hay ride

                                                          My sister being goofy! :)





Gwen being a wonderful model for me 





DJ assignment on lighting

I set up a tripod and did a photoshoot of my self. Very challenging.
Model's very enthusiastic, no?
I lessened the shadow by using a white folder as a reflector.

One light source. One hope.

I used the heart above as a light filter.

My beloved fedora.


Sandy: He's a boy

I used a flash from a couple of feet away to lighten up his face.

You can see the sun and my house in the reflection.


 It reminds me of the picture place in Chuckee Cheese's

Skyline on the glasses


A change of perspective.

Failed attempt at butterfly lighting

I like the haze of light starting from the top left corner

Light.
