WEEK 3 - DAY 2 Tonal Photography

WEEK 3 - DAY 2 Tonal Photography

Refer to the handout in class or yesterday's blog post to continue the WEEK 3 Activity on Tonal Photography.

WEEK 3 - DAY 1 - CONTRAST - LIGHT and SHADOW

WEEK 3 - DAY 1 - CONTRAST - LIGHT and SHADOW

Removing colour from a photograph or shooting a black and white can give the photograph the following affects:

-          Allow the eye to “read” black and white

-          Add drama and impact to a composition

-          Give a sense of timelessness

-          Simply the subject

Contrast in photographic composition focuses the viewer's attention to the center of interest. Positioning of subject elements to create contrast gives them added emphasis and directs the viewer's attention.

TONAL CONTRAST:

In black-and-white photography, contrast is the difference in subject tones from white-to-gray-to-black or from the lightest tone to the darkest tone. In color photography different colors can create contrast, that is another lesson.

HIGH and LOW CONTRAST: In black-and-white photography, high contrast (few mid-tones) conveys a hard edge and delivers a more severe message. Low contrast (mostly mid-tones) conveys a softer and gentler message.

Activity 1 WEEK 3 SLIDE SHOW: (see AWQ4M folder for sample)

Using 3 photographs you took on the Friday re-birth photoshoot. Focus on images with high tonal contrast. Include 1 image of tonal photography from the Internet.

STEP 1: Create a slide show and rename it WEEK 3 – TONE and CONTRAST. Create the Title slide with a tonal image you downloaded from the Internet.

STEP 2: Open the 3 images you selected from Friday’s photoshoot. Open them in Photoshop Elements.

STEP 3: IMAGE 1 - ADJUST COLOUR HIGH CONTRAST – Press [CNTL] U to adjust the HUE – SATURATION – LIGHTNESS  of your image until you have a high contrast photograph. Take a screen snapshot of the HUE Photoshop levels you changed. 

SKILL 1: Use Photoshop’s colour adjustment – CNTL U

STEP 4: SLIDE 2- Paste your HUE/SATURATION window snapshot into SLIDE 2 of your Week 3 slideshow. Make sure your snapshot includes the modified image. Insert the original image on the slide as well.

STEP 5: IMAGE 2 - ADJUST COLOUR LOW CONTRAST – Press [CNTL] U to adjust the HUE – SATURATION – LIGHTNESS  of your image until you have a low contrast photograph. Take a screen snapshot of the HUE Photoshop levels you changed.

STEP 6: SLIDE 3 - Paste your HUE/SATURATION window snapshot into SLIDE 3 of your Week 3 slideshow. Make sure your snapshot includes the modified image. Insert the original image on the slide as well.

STEP 7: IMAGE 3 - USE EFFECTS Panel to the right top of the page to create a high contrast image.

SKILL 2: Use “Effects” panel to modify image. Save image under a different name and put both images in SLIDE .

STEP 8: SLIDE 4 - Paste your USE EFFECTS modified image into slide 4, also include original image.

COLOUR CONTINUED... Describing Colors

HSB

Even though we can see colors accurately, it is very difficult to describe them without a reference point to relate them to. That is what color measurement is designed to do

To accurately describe colors for color matching, especially when we delve into the world of digital imaging and color management, we need a more reliable method. In order to describe a specific color, we need to break it down into three elements:

• Hue is the actual color. It is measured in angular degrees counter-clockwise around the cone starting and ending at red = 0 or 360 (so yellow = 60, green = 120, etc.).

• Saturation is the purity of the color, measured in percent from the center of the cone (0) to the surface (100). At 0% saturation, hue is meaningless.

• Brightness is measured in percent from black (0) to white (100). At 0% brightness, both hue and saturation are meaningless.

By using these three measurements, any color can be described so that it can then be recreated accurately throughout an imaging system. An understanding of these measurements will help you to understand the relationships between the colors in the scene that you are photographing and how these will be reproduced in the final image.

RBG

This is the scheme that you will use most often when you are dealing with colors on a computer monitor—in graphics packages, in programming, or in Web pages. RGB describes colored light which is viewed coming from its source (colored light bulbs in a theater, the colors of a video display, or reflection from a white object). It is called an additive color system, since you add light from the primary colors to make new colors.

The values for red, green, and blue commonly use a scale or measurement from 0–255. All modern video cards, which are capable of 16M colors, use one byte each (per pixel) for the R, G, and B values, so the 0–255, higher numbers mean more of each color of light. 

ACTIVITY 1

STEP 1: Using the photographs you took on your Hamilton Market field trip, select 3 images, each image should:
- feature one main chromatic colour
- establish the rate of saturation in the colour, i.e. how much black, gray or white is in the mix
- establish the colour luminance, i.e. how much light is emitted from the colour 
- establish the RGB values from 0 to 255

STEP 2: GET COLOUR VALUES: You will do this by opening your image in Photoshop Element and using the eyedropper tool to get a colour read. 
SKILL 1: OPEN PHOTOSHOP FILE: Select Photoshop Elements option from the START menu, use the EDIT option to open a image.
SKILL 2: PHOTOSHOP EYE DROPPER TOOL: One the left hand side of the Photopshop workspace, you will a tool bar,
SKILL 3: SCREEN SNAPSHOT: You can take a snaphot of the Photoshop colour chart, you can do this by [Alt] + [PrtSc] then paste into your slide show.
SKILL 4: CROP TOOL in GOOGLE SLIDES: You will need to use the CROP tool in Google Slides as well to remove parts of your screen snapshot.

STEP 3: Using the WEEK 2 Google slide show you created yesterday add 3 new pages. On each page include the image you selected with the RGB and HSB colour features described, feel free to use your screen snapshots to do this.

WEEK 2 - DAY 2 - Colour and Light

WEEK 2 - DAY 2 - Colour and Light

Light

Much of our knowledge about light derives from experiments that the scientist Sir Isaac Newton (1643–1727) carried out in the 17th century.

He demonstrated that daylight can be split into a series of colors. This sequence of colors—red, orange, yellow, green, blue, indigo, and violet—is known as the chromatic color sequence. Colors that are not part of this sequence, such as beige or burgundy, are known as nonchromatic colors.

CHROMATIC COLOUR SEQUENCE: ROYGBIV

Why Objects Appear  Colored

When we see an object lit by white light, its color is due to the object absorbing some colors and reflecting (or transmitting) others. For example, green foliage appears to be green because it contains pigments that absorb blue and red light and reflect only green light. It is a similar story when the light is viewed through an object, such as a photographic filter. You only see the part of the spectrum that is allowed through. For example, a blue filter blocks red and green light, and allows only the blue part of the spectrum through.

Measuring Colors

Human vision is very good at recognizing the differences between two colors seen side by side. However, it is a different story when it comes to accurately describing individual colors to someone else.

While our eyes cannot see ultraviolet or infrared radiation, these can have an effect on the image produced by both digital sensors and film. In most circumstances, it is undesirable for the image to register radiation outside of the visible spectrum.



The nature of light itself is still the subject of much speculation. Current theories explain light by giving it the properties of both waves and particles. We will deal primarily with the wave theory; this explains the aspects of light, such as wavelength and frequency, that concern us in color photography.

Light Waves

Light waves are the visible part of a much larger group of waves known as the electromagnetic spectrum, which includes X-rays and radio waves. The  range that is present in daylight is shown below. This ranges from the short-wavelength ultraviolet to the longer-wavelength infrared, with the visible portion in between.

ACTIVITY 1

STEP 1: Using the crystal and a light source take at least 3 images of the chromatic colour, i.e rainbow that you get when you sign a flashlight into the crystal.

STEP 2: Create a Google slide show titled WEEK 2 - Colour, and create your first slide with the image you took of the chroma colour light split and a description of the image. 

SUGGESTION: Access the you tube video using "mandelbrot set" as a search to show light images, you can take images of the screen as a substitution for the crystal images.
