Photo 2, Week 3; (May 1-5) TIME EXPOSURE Photography
How does Shutter Speed Effect the Result of a Photograph?
Copy these notes 5-1,
B) Focus before you start using Manual focus (or set to infinity)
C) Set the DSLR camera to a long shutter speed using the Mode set to TV (Time-value and then choose a slow time like from 10-30 seconds)
D) Set the ISO to the least sensitive (100) then adjust upward if you need to brighter (more sensitive).

Eric Staller: Light Painting Photography, 1976
Eric Staller could be called the Father of Light Graffiti (also known as Light Drawing, Writing, or Painting, in its present day form).
From 1976 to 1980 Staller roamed the dark streets of New York City creating light painting photographs:
These were done around 1980 - before digital photography (digital was not commonplace until around 1995) - so this is using color film.
In Photo 2 Class we will use this concept with digital cameras to explore Digital Photography.
You may even want to try this on your own --even Download an AP for you cell phone that takes photos letting you do this:
A pixel is actually a unit of the digital image.
It has to do with the size of the image and how well it will print when enlarged.
Resolution refers to how many pixels in an inch.
There is high and low resolution
Resolution (or also called the dpi) : describes how many pixels in a photo, written in a number that tells how many “dots” Per square inch of the image; two examples are - 72 dpi (which is very low resolution) or 300 dpi (which is a high resolution). dpi can be higher but is only necessary if you are enlarging the image to be a poster or a billboard size. For normal everyday size prints, 300 dpi is fine.
ABOVE: This is an enlargement of the edge of th "O" above. The left image shows a lower resolution than the right image; the more pixels that make up an image the more detailed and smooth edged it will be. The one on the left will look blurry when reduced, the one on the right will look cleaner and crisper to the naked eye.
For use on the web use 72 dots per inch (looks “OK” on a screen)
But Best for printing – is 300 dpi, it will have more detail, see below
Sometimes Pictures come out of cameras HUUUUUUGE but at a low resolution of 72, huge photos are big files and are hard to store, work with, or save to flash drives, email, or even to use on the web. The web likes 72 dpi resolution-it travels through the internet easier. Photographers do not like 72 dpi, it is not detailed enough to PRINT from.
To work in Photoshop and print, you should change all photos from 72 dpi to 300 dpi at "image size" also changing the size of the image in that same window to about 9” by 12” or else the images will be 5 feet wide. This is an enlargement of how a photo looks if you don't do this:

SD Cards: Secure Digital (SD) is a memory card format developed for use in portable devices which has become the industry standard.
(The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC).
DCIM: Digital Camera Images, a directory name in the Design rule for Camera File system (DCF, or “Design rule for Camera File system”), part of the file system for a digital camera. On a computer, when you open the folder for the SD card you may see subfolders, the one that says DCIM will hold the images.
The DCIM folders on smartphones serve the same purpose. When you connect an iPhone or Android phone to your computer, the computer or photo-library software can notice the DCIM folder, notice there are photos that can be transferred, and offer to do this automatically.
DCIM may not be the most obvious name the first time you see it — how about “Photos”? — but it’s more important that it’s a standard. If every digital camera manufacturer or smartphone operating system had its own unique pictures folder, software programs wouldn’t always be able to automatically find photos on a connected device. You wouldn’t be able to take an SD card from one camera and plug it directly into another digital camera, accessing the photos without reformatting the device or rearranging the file system.
Card Reader: an electronic device that reads and transfers data from various portable memory storage devices. Care must be taken inserting card!
