Layers and Compositing

We recently had an interesting project that taught us how to compile six images into one image. Photoshop was used to get every single image to have a transparent background. There were a few tools we used such as the magic wand tool that automatically selected the defined parts of the image. But we could not use this on every single picture. For instance the sheep in the light bulb; we couldn't just use the magic wand tool the select what was needed. Instead I used both the magic wand and regular selection tool.

Semiotics
The definition of semiotics is the study of signs. It has a total of 3 categories; iconic, indexical, and symbolic.

• Iconic: a sign that stands for its object of  resemblance to it
• Indexical: something used to point out a sign
• Symbolic: serving as a symbol

 My Symbol

This is the old Arizona Western College sign . Overs the years is changed but it still gives the same meaning. To me it is a symbol of education. A mountain that everybody climbs to better themselves.

 

Color Mode Exercise

RGB

This is a regular picture saved in rgb (red,green, and blue) color mode. Its uncompressed file size is 68.7m # of colors is 256.

Indexed Color

It is the same picture but I changed the color mode via Photoshop > image > mode > indexed color. The uncompressed file size 1.83m with 9 colors total.

Grey scale

It looks similar to indexed color except grey scale uses all 256 all the time. The uncompressed

file size is 1.83m with 256 colors.

Bitmap(color mode)

Bitmap has on two colors (black/white) you can get to this by change the image to grey scale then bitmap. The uncompressed file size is 234.4k with only to 2 colors.

 Pre-quiz

Can you change FILE FORMAT  just by changing the name?

 You can not change a file format by changing its name it doesn't work. 
 What is the # of colors in each Color Mode?

•  RGB: 256 
• indexed color: 0-256
• grey scale: 256
•  Bitmap: 2 

What happens to the (uncompressed) FILE SIZE as you change the COLOR MODES?
Changes the amount of data for the file.
What happens to the visual quality of images as you REDUE the # of colors by changing the color mode?
It changes the amount of color and data.
What is a good reason to convert PSD files to JPG?
When delivering a file .

Color Rubbing

Goals Of The Project

These are two color rub drawings that our instructor had us do one day. The goal was to try and find the meaning behind the picture. Why we chose these colors for our background, symbol, and word.

My Critique

The first picture has a symbol of a girl with a green background overlapped by purple lettering. The  girl overlapped with the purple letters to show she wants being educated or is interested in this program. The second picture has the number 4 and the Arizona Western College symbol. It could mean that someone is going to this school for 4years.
