First day of class!

Can you tell I'm excited for class to start?!  Best part is I'm taking the class with my friend Sarah.  Day 1 we met the instructor and other students in the class.  He went over a few basics and told us why all our pictures suck.  But that is all about to change.....

What we learned on Day 1

- How pictures are captured, mega pixels and memory.
So if you have a 12 MP camera - it contains 12,000 receptors that capture light.  The receptors are divided into 3 colors (red, green, blue) that capture the light.  The light then turns into electricity then into a number.  This number is the RAW data.  Most cameras are set up to save as JPEG - which cuts the size of the picture way down...the camera makes a few general assumptions about the picture (like maybe generalizing a white back ground to only one shade of white vs. the true multiple shades it contains) so you loose a lot of the detail.  FYI......every time you re-save a JPEG, you're actually loosing more data.  I think he said you can save a JPEG 90 times before its nothing.  When working in PhotoShop - most likely saving the file as TIFF.  With TIFF, you won't loose data every time you save. We'll be working with RAW eventually.

- Six qualities of Light
  • Brightness
  • Direction
  • Color (Cool, Neutral, Warm)
  • Contrast (Hard vs. Low)
  • Specularity (refers to the size of a light source - so think a bright sunny day)
  • Diffuse (think a cloudy day)
We had a little quiz to see if we could identify the different light qualities....I might not have a natural eye for these things.  I have a lot to learn!

First assignment - we have to take 13 pictures using the above light sources.

  1. Love the blog. Can't wait to see all of your photos and hear all about your class. I'm hoping to learn a thing or two from your blogging.
