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