Digital images and difference between print image
+
==Project overview==
 +
*Adobe Photoshop and inDesign and how we will be using them for these projects
 +
* '''Preparing digital images for print.''' Photo Quality prints need thousands of linear pixels. This means between 180 and 360 pixels per inch (ppi.) So, if a print is 10” long, you need 1800 – 3600 linear pixels for it to look good. (10” x 360=3600pixels). By contrast, images for the web or email need to be sized for screen resolution. Depending on the monitor you’ll need 800-1920 pixels to fill the screen.
 +
 
 +
===Best practices===
 +
*'''Start Big:''' larger image files (both in file size and in overal number of pixels) provide you with higher quality images. You can always scale the image down but you can't scale it up.
 +
*'''Keep your original:''' These images are typically your highest quality image and you may need to go back to them from time to time.
 +
*'''File naming is important:''' Come up with a naming convention that helps you quickly identify the image without having to open it up. Names should include descriptive info, version, size or intended use.
 +
**Example: Rainier_sunrise_1200_BW.psd - this file name tells me about the subject of the photo, the image size typically its width and any processing I've done, this one is a black and white version, its file format is Photoshop.

−
#Launch InDesign and open the BETWEEN.indd file from within your project folder
+
−
#Go '''File > Save As''' and rename it with ''yourlastname_partnerlastname''.indd
+
−
 
+
−
===Margins and Guides===
+
−
#Note the margins of your document. Make sure to keep your text and artwork within this boundary
+
−
#Add a '''Guide''' to help you place and align objects on your document
+
−
#*With the black arrow select tool, click and drag from the ruler area into your document
+
−
===Adding Text===
+
−
# Select the '''Text''' tool and drag diagonally to create a frame on your document, start typing.
+
−
#*You can also '''Copy''' and '''Paste''' text from other applications
+
−
#Using the black arrow tool select a corner of the bounding box to rezize
+
−
====Text Flow====
+
−
You can flow text between multiple text boxes
+
−
#Text boxes that are too small to contain all of the text will have a red + box in the lower right corner
+
−
#Click this box and the cursor changes to the "Text Loaded" cursor
+
−
#Click anywhere on your document and a new text box will be created flowing text from the previous text box
+
−
#Use Guides and your Margins to snap text boxes into alignment
+
−
====Formatting Text====
+
−
#Select the text you want to format ('''Command A''' to Select All is a useful shortcut here)
+
−
#Change your type using the character and paragraph options in the top property bar
+
−
 
+
−
===Add an image===
+
−
By default, images placed into InDesign are only linked. It is important to have a good file management strategy to keep your images properly linked to your InDesign document.
+
−
#Make sure nothing is selected in your document before you place your graphics!
+
−
#Go '''File > Place''' to place your image
+
−
#Locate the image on your local hard drive that you want to place and click '''Open'''
+
−
#Your cursor changes to the "Image Loaded" cursor. Click your cursor where you'd like the image placed.
+
−
 
+
−
====To resize your image====
+
−
With the black arrow select tool [[File:Indesign-select-tool.png]] selected
+
−
#hold down the '''Command''' AND '''Shift''' key then grab a corner of the bounding box and drag to resize.
+
−
#*Note what happens if you forget to hold down these keys...
+
−
====To crop your image====
+
−
With the black arrow select tool [[File:Indesign-select-tool.png]] selected
+
−
#click and drag the bounding box (without holding down CMD+shift).
+
−
====Move your image====
+
−
#To move a frame together with its content, use the black selection tool [[File:Indesign-select-tool.png]] to click the image outside the content grabber.
+
−
#To move imported content without moving the frame (that is, to pan content behind its frame), drag the content grabber. [[File:Content-grabber.png|right]]
+
−
#*You can also use the Direct Selection tool [[File:Indesign-direct-select-tool.png]]  to select and drag the image.
+
−
 
+
−
===Text wrap around an image===
+
−
#Select the image and from the top properties bar choose the text wrap option you'd  like
+
−
#Move a text box near/over and image to see the text wrap around the object
+
−
 
+
−
===Wrapping it up===
+
−
Placed images in InDesign are by default only linked to the original image files. There are advantages to this but it can create problems when moving files around. You must move your graphics and images together (see File Management strategies above).
+
−
 
+
−
 
+
−
====Packaging your project for print====
+
−
'''Your final step'''  is to "package" your InDesign document. This should be done when you are finished editing your document. This process creates a new project folder, a copy of your inDesign project file, a subfolder called "Links" for all of your linked images and folder called Document fonts for your fonts.
+
−
 
+
−
#Save your work '''File > Save'''
+
−
# Go '''File > Package'''
+
−
#Click '''Package'''
+
−
#Add any special instructions and click '''Continue'''
+
−
#Create the package folder.
+
−
#*Note the package options. You can accept the default of packaging the top three options from the list.
+
−
#*Name your folder ''yourlastname_partnerlastname_final''. Save locally first, you will eventually copy this over to Orca/programs.
+
−
#Click '''Package'''.
+
−
#Click OK at the copyright warning
+
−
#InDesign will now create a new folder that contains a copy of your project as well as all linked images in a '''Links folder'''.
+
−
#Copy the entire folder back to Orca/Programs/between-word-image/workspace/Book-final-versions.

Project overview

  • Adobe Photoshop and inDesign and how we will be using them for these projects
  • Preparing digital images for print. Photo Quality prints need thousands of linear pixels. This means between 180 and 360 pixels per inch (ppi.) So, if a print is 10” long, you need 1800 – 3600 linear pixels for it to look good. (10” x 360=3600pixels). By contrast, images for the web or email need to be sized for screen resolution. Depending on the monitor you’ll need 800-1920 pixels to fill the screen.

Best practices

  • Start Big: larger image files (both in file size and in overal number of pixels) provide you with higher quality images. You can always scale the image down but you can't scale it up.
  • Keep your original: These images are typically your highest quality image and you may need to go back to them from time to time.
  • File naming is important: Come up with a naming convention that helps you quickly identify the image without having to open it up. Names should include descriptive info, version, size or intended use.
    • Example: Rainier_sunrise_1200_BW.psd - this file name tells me about the subject of the photo, the image size typically its width and any processing I've done, this one is a black and white version, its file format is Photoshop.

Scanning

Using the Epson scanners in the Computer Center. See: Scanning - Mac

  1. Scan one drawing from a station connected to a scanner
  2. Save as TIFF to your cubby on Orca. See: Connecting to Orca programs at File Space Overview
  3. Go back to your station and copy your scanned image to your local harddrive

Intro to Photoshop

Photoshop interface and navigating an image

  1. File > Open your scanned document in Photoshop
  2. Keyboard shortcuts for navigating your image
    • Zoom in/out: Cmd +/-
    • Hand tool: Space Bar
  3. Image > image Size to see the overall size and resolution of your image
    • for print, image resolution should be at least 300 dpi
  4. File > Save as choose Photoshop as the file format. Note the .psd extension.

Editing your image

  • If needed, rotate your image Image > Image Rotation
  • Crop and set the horizontal/vertical alignment for your image using the crop/align tool (we will be able to crop our images later in indesign as well)
    • Note what happens if you choose Not to "delete cropped pixels"
    • this relates directly to you Canvas size found in Image > Canvas Size


Image Adjustments

  1. Image mode
    • All images must be in RGB mode. Go Image > Image mode and set the mode to RGB if it is not already
  2. Adjust the image density (overall brightness/darkness of an image)
    • Image > Adjustments > Brightness and Contrast is the most basic way to do this
    • Image > Adjustments > Levels give you even more control and can work to clean-up scanned drawings or bring added depth the dull snapshots
    • Adjustment layers are a more flexible option

Image Touch up

  1. Working with Layers
