Review and Discuss

1.      List advantages of using photos from your own camera. LO 9.1

   Photo can be always changed whatever you want and post to wherever you like

2.      Evaluate two specific situations in which photos are needed, citing the advantages and disadvantages of using stock photos in these jobs. LO 9.1

1.Use photos to explain the data

            2.Use photos to show the example.

Advantages:  they are available at different resolutions, sizes, and file types.

Disadvantages: it includes a watermark, a pale image or text embedded in the image, to discourage unauthorized use.

3.      Analyze what should be considered when choosing an image size and resolution in the following scenarios: a) Image will be used on the Web. b) Image will be used in print publishing. LO 9.2 and 9.7

You should consider the citing of the photos, size and the resolution and so on.

4.      Identify and describe in detail what most owners of stock photos do to ensure that the stock photo is not used without purchasing. LO 9.4

Stock photos are images made available for use in creative and commercial projects, typically for a fee, they are usually cataloged using keywords. And it includes a watermark, a pale image or text embedded in the image, to discourage unauthorized use.

5.      Define screen captures and evaluate their use in tutorial documentation. LO 9.2

Screen captures are a snapshot of a computer screen generated by the OS or other dedicated software. It is useful where showing the actual computer display is essential to the topic.

6.      Identify when it is appropriate to use a scanned image and when it is not a good idea. LO 9.2

You can scan a hard copy document to create a digital file, do not use scans of hard copy images as a shortcut or because the actual digital file is too costly or protected by copyright.

7.      Explain royalty-free licensing and give examples of what may be included in the licensing agreement. LO 9.4

Royalty free means the buyer pays a one-time fee to use the image for an unlimited number of products and for an unlimited length of time without paying any additional fees for each additional use.  Example: Ethical and legal guidelines.

8.      Differentiate between rights-managed licenses and royalty-free licenses. LO 9.4

Royalty Free license grants non-exclusive, unlimited and multiple use of an image, with few restrictions. Rights Managed license provides time and geographically limited, specific and per-use rights to use an image, and often times also grants exclusive usage during the licensed period.

 

9.      List some reasons it may be best to resize images in a raster editing program before placing them in a layout program. LO 9.5

you can ensure you aren't creating any low-quality images by resizing in InDesign. If the effective PPI is at print resolution or higher, the image is fine. If the effective PPI is lower than print resolution, you are creating "broken pixels" in the image. Upon export to press-ready PDF or printing, higher PPI is reduced to print resolution and the image is fine. Lower PPIs are not increased upon output, so the image will lose quality.

 

10.  Describe resampling, downsampling, and upsampling in a raster image. LO 9.6

Resampling : changed according to interpolation.

Upsampling : an increase in pixels

Downsampling :a reduction of pixels, decreases the file size
