ISO Assignment

At last, we've reached the third element in the EXPOSURE TRIANGLE! {doesn't it sound mysterious?}

Under the belt so far are Aperature & Shutter Speed. 

Last, but certainly not least...ISO! If you've been following along with the other tutorials, then you would already know that we are talking about curtains. Aperture is the curtains of your camera because it controls how much light you are letting in your camera. Shutter speed is how long you are leaving your curtains open. That leaves ISO, which is similar to the strength of the light coming through your curtains and how your camera reacts to it.

I must admit - there wasn't as much of an obvious difference in the pictures this week as compared to the jaw-dropping {well for me, at least} differences in the past two lessons. But...I am needing to learn one element at a time in order to shoot in FULL ON MANUAL MODE {shriek!}. 

For this assignment, I shot photos of seashells in natural light. HOLD UP! First, I must share a couple pictures of where the seashells came from. It's GORGEOUS. This is the Marriott Marco Island Resort and Spa, where we visited in the fall:

{Sigh} 

Okay, back on task. Here's my ISO shots.  I did not edit these pictures because I learned higher ISO's  can show a bit more grain because of the bigger influx of light. I was hoping the lack of editing would help us to see that! Here they are...

You can see a little bit how the picture on the right is different? If you look at the largest shell, I can see it's a little more grainy on the left, more than in the first picture, at a lower ISO, which is on the right directly above. 

Fingers crossed I did it right! Looking forward to next week's lesson from Aimee at It's Overflowing!
