14 b. About layers:
In Photoshop as you add new things to a picture they are added in new layers. Layers allow you to work on one element of an image without disturbing the others. Where there is no image on a layer, you can see through to the layers below. You can change the composition of an image by changing the order and attributes of layers

17 2. Picture properties and theory :
A. Pixels and resolution: I. Definitions : -Pixel = the small dots that make up a digital picture
-ppi = pixels per inch or the number of pixels per inch in a picture. Another similar measure of this is dpi = dots per inch , which is used with printers. -Resolution = the number of pixels per inch (ppi) or the size of dots (i.e., pixels) that make up a picture. As the ppi increase the size of the pixels that make up a picture gets smaller and the detail in the picture increases. Higher resolution pictures have more pixels per inch and can be made larger without pixilation occurring. 1 inch
-8 ppi -smaller pixels -more detail in the picture
-4 ppi –larger pixels -less detail in the picture -Pixilation = when the pixels in a picture are enlarged to the point that they are visible on the picture. This reduces the detail visible in the image and the quality of the image.
8/31/2006
Photoshop CS8.0 Manual Created by Jeffrey Hill - Parts of this manual came from John Burt and Grant Anderson
18 II. Image enlargement or magnification and pixel size: When a picture is made larger in dimension you can lose resolution as the effective pixel size increases. As you enlarge or magnify an image Photoshop it creates new pixels because it maintains a constant ppi for the image.
4 IMAGE PIXELS
4 SCREEN PIXELS (1:1 RATIO)
-This is the ideal situation. For every screen pixel there is one image pixel. This is the biggest size the image can be magnified to without becoming distorted.
16 SCREEN PIXELS (1:4 RATIO) 4 IMAGE PIXELS Enlarged or Magnified
-What has happened now is that the image lost resolution because in effect the pixels have gotten larger. The ppi of the image has not changed, but to make the picture large one pixel has to been made into four. The resolution of the picture has gone down because the size of the color dots making up the picture has increased. III. Resolution and printing: Resolution also controls how large you can print an image without pixilation occurring. The higher the resolution the larger you can print an image without pixilation occurring.
Example: Printing the same low-resolution image at different sizes A. Small print size B. Medium print size C. Large print size 8/31/2006

19 IV. Standard resolutions : Note, always keep image resolution high while you are working on it in Photoshop. Only reduce the resolution when you need to reduce file size for the specific use of the image. a Photoshop : 1.0 -9,999 ppi -When you create a new document it will be 72 ppi unless you change the resolution setting. -This is the standard resolution used for web images.
b. Monitor resolutions : 72-96 ppi -Most older monitors are 800 x 600 pixels for a standard 11 inch by 8 inch display which is 72 ppi -Most newer monitors are 1024 x 768 pixels for a standard 11 inch by 8 inch display which is 96 ppi ***If you are making images for the web you should to reduce their file size to reduce their load time. You should save images for the web at no more than 96 ppi, unless you want the user to be able to magnify the image. c. Mega pixels and digital cameras : The term megapixel means one million pixels. The megapixel number for a camera equals the number of pixels it uses to make a picture. The number of magapixels required for a camera depends on the size you want to view or print pictures at. At least 4* megapixels is genrally recommended for amateur photographs and a minimum of 6 megapixels for advanced photographers. It takes about 8** megapixels for a digital camera to begin to approach the picture quality of a regular 35 mm film camera.
Example: Maximum picture size with a 2 megapixel camera at 300 ppi - (5.8 inches x 3.8 inches)
5.8” x 300 ppi = 1740 pixels in length 3.8” x 300 ppi = 1140 pixels in width 1740 ppi length x 1140 ppi width = 1,983,600 or almost 2 megapixels

d. Printers resolutions: 300 -600 dpi -Economy printers have a resolution of 300 dpi -Standard quality printers have a resolution of 600 dpi. -High resolution photograph printers have a resolution of 1200 dpi -Ink jet prints have a resolution of 300-600 dpi
Printer resolution related definitions: Pixel = the small dots that make up a printed picture Pixels per inch (ppi) = the number of pixels per inch in a picture. Dots per inch (dpi) = the small dots used to make a grey scale or color images by printers. Halftoning (or screening) = the process of using multiple dots to represent a single pixel in a printed image. Dither (dithering) = number and pattern of halftone dots used to create pixels in a printed picture. Lines per inch (lpi) = the number of halftone dots a printer can print per inch of paper . Lines per inch is a measure of printer quality. 8/31/2006
Photoshop CS8.0 Manual Created by Jeffrey Hill - Parts of this manual came from John Burt and Grant Anderson
21 More information on printer resolution: Printers print specific dots on the page to make pictures, so their resolution is measured in dpi (dots per inch). For simple printers, that print only in black and white, each character is made up of a number of black dots and the dpi (dots pre inch) equals the ppi (pixels pre inch).
Most printers can’t print continuous color tones — whether it's the many shades of gray in a grayscale image or the millions of colors in a color photograph. In order to make shades of gray or colors, most printers uses a concept called halftoning (or screening) and use multiple dots to represent a single pixel in the image. Each dot is either on or off, but the array of dots looks lighter or darker depending on how many dots are in it. With theses printers there is not always a direct relationship between dpi (dots pre inch) and ppi (pixels pre inch) . The printer can use multiple tiny dots to express the content of one pixel. Therefore, your printer resolution can be set at 1440 dpi, but your printed image will only have a resolution of 300 ppi. For color images the printer uses four colors of halftone dots: cyan, magenta, yellow, and black. Every individual pixel in your image will be represented by a random pattern of these smaller, various-sized printer dots. Dither or dither pattern refers to number and pattern of halftone dots used to create pixels in a printed picture. Different dither patterns can result in differences in image quality. Dithering matches colors more closely. If no dithering is used the program just uses solid color dots of the color closest to the original color in the picture. GIF image with 0% dither (worse), and with 100% dither ( better )
The number of halftone dots a printer can print per inch of paper is know as the lines per inch (lpi). Lines per inch is a measure of printer quality. The lines per inch determines the size and spacing of the dots that make up pixels. If the lines per inch is high it means halftone spots (i.e. dots) are small and close together so less discernible to the eye. The higher the lpi of a printer the better quality image it can print. Lines per inch is also known as the line frequency or screen ruling . e. Recommended scanner resolutions for scanning materials: The scanner resolution you use depends on the material you are scanning and how you plan to use it. For materials you plan to modify in Photoshop or increase in size it is best to scan at a very high ppi for working with the materials in Photoshop and then reduce the ppi when saving the materials for their specific use.

f. Making posters: The resolution of images used on posters depends on the size of the poster and the enlargement of the pictures, but for standard sized posters where an image will be blown up to approximately 8” x 12” (20cm x 30cm) resolution of the original image should be no less than 200 ppi and preferably 300 ppi. Note, most images from the web (72 ppi) will be come pixilated if used on a poster.

g. Maximum pixel dimensions allowed in Photoshop : 300,000 by 300,000 pixels per image . 300,000 x 300,000 @ 300 ppi = 83 ft x 83 ft or 25 m x 25 m 300,000 x 300,000 @ 200 ppi = 125 ft x 125 ft or 38 m x 38 m -Note, that your computer probably does not have enough scratch memory to handle a document this size. -Older versions of Photoshop limited the pixel dimensions to 30,000 x 30,000 for images 8/31/2006

23 B Types of images used by Photoshop :
I. Raster = Raster images are made up of small dots. This type of image will distort (pixilate) if enlarged enough. Photographs are raster images. II. Vector = Vector images are made by mathematical equations so they do not distort (i.e., pixilate) when they are enlarged or reduced. An example of this is the equation for a circle. C. Colors and color models: I. Bit color and number of colors : -Each bit is binary either on or of

-4 BIT COLOR: Here we have 2 or 16 possible values. Each sequence of zeros and ones is assigned to 1 color, so it takes 4 times the memory of 1 bit color. -Note, that color depth can go up to 64 bit color for certain file types II. Color models: A color model determines the model used to display and print images. Photoshop bases its color modes on established mod els for describing and reproducing color. In addition to determining the number of colors that can be displayed in an image, color models affect the number of channels and the file size of an image.
a. HSB model (Hue, Saturation and Brightness Model): This model is based on the human perception of color and describes a color based on three fundamental characteristics of color: 1. Hue: This is the actual color. It is measured as a location on the standard color wheel, expressed as a degree between 0° and 360°. In common use, hue is identified by the name of the color such as red, orange, or green.

Sets the Flow – how quickly a brush paints as a % (100% = fast)
Sets the opacity ( i.e., how transparent a layer is): % = the percent of the previous state removed.
Def. Opacity = specifies the maximum amount of paint coverage applied by the brush or how transparent it is. Opacity can be set for the Paint Brush, Pencil, Clone Stamp, Pattern Stamp, History Brush, Art History Brush, Gradient, and Paint Bucket tools. Opacity ranges from 1-100%: -1% = very low coverage or affect (transparent ) -100% = high coverage or high effect (not transparent ) Def. Flow = specifies how quickly paint is applied by the Brush tool. A low setting produces a lighter stroke.

Image size in pixels or percent
Change the measurement units here
Image print size Resolution Constrain proportions – keeps the height and width of an image in the same proportion as you change the size
Always: Resample Image -Bicubic sampling is best
When you change the size or resolution of an image, you change the number of pixels making up the image and you need to resample pixel colors to get the best image -Note, if only reduce resolution on an image when you are saving it for a specific use. Always use the resolution of the original image when you are working on images. -Note changing the resolution of an image changes its pixel dimensions, but not its print size. Increasing the image canvas larger than the picture size: >Image >Canvas Size –increase the canvas dimensions so it is larger than the image

In Photoshop as you add new things to a picture they are added in new layers. Layers allow you to work on one element of an image without disturbing the others. Where there is no image on a layer, you can see through to the layers below. You can change the composition of an image by changing the order and attributes of layers.
-Illustration of how transparent areas on a layer let you see through to the layers below
B. Layers pallets (viewing and selecting layers): 1. You can only see layers with the small eye next to them 2. You can only work on the selected layer highlighted in blue 3. To move a masked object like a shape, the shape and its vector mask must be linked

20. Modifying picture properties: brightness/contrast and hue:
Adjust the upper and lower layers for the channel chosen here
A. Brightness and contrast: Brightness = How light or dark the image is. Brightness is also know as luminosity. Brightness is the relative lightness or darkness of the color, usually measured as a percentage from 0% (black) to 100% (white). Contrast = Is a measure of difference between the lightest and darkest values appearing in an image. High-contrast images contain mainly dark values and white values with few tones in between in the image . 8/31/2006

75 D. Using the auto-contrast command: Auto contrast automatically increases the contrast of an image making the highlights appear lighter and shadows appear darker. >Image >Adjustments > Auto Contrast
E. Adjusting brightness in each channel (RGB): Adjusting Levels: >Image >Adjustments > Levels Choose the channel (i.e., Red, blue or Green) here
Average color value
Move → to increase brightness (reduce black tones)
Move ← to decrease brightness (reduce white tones)
Note, moving both of these selectors toward the middle reduces the contrast of the image. Moving them away from the middle increases contrast.
F. Using Auto Levels to adjust contrast : The Auto Levels command automatically adjusts the black point and white point in an image. Auto Levels analyzes each color channel independently and makes the darkest color in each channel black and lightest color white . The intermediate pixel values are redistributed proportionately. As a result, using Auto Levels increases the contrast in an image because the pixel values are expanded (as opposed to being compressed, as in lower contrast images). Because Auto Levels adjusts each color channel individually, it may remove color or introduce color casts. >Image >Adjustments > Auto Levels

76 G. Auto colors adjustment: The Auto Color command adjusts the contrast and color of an image by searching the actual image to identify shadows, midtones, and highlights. By default, Auto Color neutralizes the midtones using a target color of RGB 128 gray, and clips the shadows and highlight pixels by 0.5 Auto Color deepens shadows and lightens highlights on a channel by channel basis . It increase contrast while doing a better job of maintaining the orginal colors in and image than either Auto Contrast or Auto Levels do. >Image >Adjustments >Auto Color H.
