The document discusses different sources for obtaining images, including books, Google Images, stock image libraries, copyright free sites, and taking your own photos. It outlines the advantages and disadvantages of each source. For example, books provide reliable images without an internet connection but images must be scanned, while Google Images offers a vast selection online but images are only available digitally. The document also covers processing images, such as cropping, scaling to different sizes, and using different resolutions for print versus web. Manipulating images through techniques like multiple exposure is described as well.

1. Image Sources

2. Images sourced from books:

3. Advantages of sourcing images this way:
• A reliable physical copy that doesn’t require an internet connection.
• Once you’ve purchased a book, you can have it forever and the images
that you have are freely available to you.
Disadvantages of sourcing images this way:
• Not available online and so has to be scanned in by a printer for
sourcing.
• If you can’t find what you’re looking for in a specific book then you’ll
have to use another way to get images or buy a different book.

4. Images sourced from google images:

5. Advantages of sourcing images this way:
• It is estimated that there are around 1 trillion images indexed on Google
Images. Lots of choice on virtually any topic.
• Easy to access and freely available online.
Disadvantages of sourcing images this way:
• Not available in a physical medium, purely liquidated and online.

6. Images sourced from stock image library:

7. Advantages of sourcing images this way:
• Good way to source professional looking images if you’re not a
professional photographer.
Disadvantages of sourcing images this way:
• Costs a lot of money.
• Unless you print something out, there is no physical copy available.
You’re paying for the rights to download the image and print it off
whenever you need.

8. Images sourced from copyright free site:

9. Advantages of sourcing images this way:
• Free high res images that looks professional.
Disadvantages of sourcing images this way:
• Slightly more limited selection of images, especially than a stock image
website and so it is restricting.
• Only available online unless you print the images out (which costs
money).

10. Images sourced from your own existing images:

11. Advantages of sourcing images this way:
• It’s free and mine to use.
• Can get exactly the image that I want (within reason).
• Can be rewarding to study or to just as a hobby.
Disadvantages of sourcing images this way:
• Taking your own images can be time consuming and expensive. For
example, you have to have your own camera.
• You have to find the subjects yourself, and you might not always get
what you wanted.

12. Processing

13. Original image:

14. Cropped image:

15. Scaled images:
A4
A5
A6

16. Resolution image:
300dpi for print
72dpi for web

17. Advantages of different resolutions:
Low and high resolution images both have their advantages and
disadvantages. An advantage of low resolution images is they have a
smaller image size and are good for using in PowerPoints to keep the
image size down and potentially send over email. An advantage of high
solution images is that they are more aesthetically pleasing and retain the
original image quality.
Disadvantages of different resolutions:
A disadvantage of low resolution images is that they do not retain the
original image quality and so can appear pixelated. A disadvantage of
high resolution images is that they can have a much larger file size and so
more demanding when uploading/downloading or sending via the
internet.

18. Manipulated image with appropriate caption:

19. Explain the changes you made to the image and explain why you made
those changes:
I completely changed the image. I used a technique called multiple
exposure to overlay an image on top of the other. I made this change to
make the image unique and diverse, and more visually interesting. In
Photoshop, I used multiple filters to edit the image and balance it
correctly so the image was optimal. The smart filters I used are levels,
curves, brightness/contrast, exposure and vibrance. I used these to
balance the white and blacks in the image and make sure it was as clear
as it could be. It was difficult as in one of the images, the background is
completely black and in the other completely white, so finding a middle
ground proved challenging.
