7. Have you seen the changes?

8. What do you think was done on the
pictures?

9. What are the effects of the changes? Were
they done for advertising, for entertainment,
for emphasis, for other effects?

10. Do you think you can create those
changes? How?

11. Do you want to be a good photo editor?
Why?

12. IMAGE EDITING
• Image means….
– Photographs
• Digital
• Analog
– illustrations
• Edit means…
– Alter
– Change
– Modify

13. IMAGE EDITING
• The process of altering, changing, modifying,
whether they are processed photographs,
traditional analog photographs or illustrations

17. Image Editing Softwares
• Are the primary tools with which a user may
manipulate, enhance and transform images.
• Also used to render or create computer art from
scratch.
Examples:
Adobe Photoshop Corel
Picasa Pixia
GIMP

18. Basic of Photo Editing
1. Cropping – a technique where you cut out
distracting background or a clutter of irrelevant
objects around an image.

19. Study the picture below.
What can you say about the picture?

21. • In cropping, always use the golden in
photography-
“rule of thirds”
Remember this!

22. Basic of Photo Editing
2. Resizing /Resampling
Resizing – changing the size of the image
depending on the usage
Remember!
Save a copy of your image before you resize it
so that you use it at a different size in the
future.

23. Basic of Photo Editing
2. Resizing / Resampling
To learn further about the resizing, try
to look at the following terms:
Pixel
Resolution
Have you encountered these words before?
Can you tell the class about them?
Play video

24. Basic of Photo Editing
2. Resizing / Resampling
Resolution – refers to the number of
dots per inch (dpi) that appear in our
image.
Pixel – Number of dots on the screen
But they actually look like small square

25. Basic of Photo Editing
3. Adjusting the Brightness/Contrast
Brightness – the amount of light of an
image
Contrast – defines the separation between
the darkest area and brightest areas of
the image.

26. Basic of Photo Editing
3. Adjusting the Brightness/Contrast
Increase in contrast and you increase the separation between
the dark and the bright, making shadows darker and
highlights brighter.
Example of Contrast:

28. Basic of Photo Editing
4. Sharpening and Softening
• Sharpening is a tool that gives emphasis on
textures and for drawing viewer focus.
Note:
Excessive image sharpness will always
increase the amount of contrast and distorts
color relationships.
Softening- is the opposite of Sharpening

29. Basic of Photo Editing
• Sharpening and Softening

30. Basic of Photo Editing
5. Automatic Image Enhancement
• Basic automatic image improvement features
in camera and image editing programs
• Corrects color imbalances, red eye reduction,
sharpness adjustments, zoom features and
automatic cropping
• Why automatic?
– Because it happens with less user interaction or is
offered with one click of a button

31. Basic of Photo Editing
6. Data Compression
- many image file formats use data
compression to reduce file size and save
storage space
Some File formats that use data compression:
JPEG – Joint Photographic Experts Group
PNG – Portable Network Graphics

32. Key Terms and Definition
• Photoshop Document (.psd) – is the file
format in which Photoshop saves documents by
default. It is a multi-layer document that retains
its full editing options when saved.
• Layers – the ones that composed a Photoshop
document. These are single transparent sheets
which hold particular pieces of an image. These
layers can contain images, text and vector
graphics

33. Key Terms and Definition
• Selection – refers to the region in an image
that will be affected by the various tools.
• Resolution – refers to the number of pixels in a
full size image
• Image Size – actual size of the image
considering its height and width size

34. Key Terms and Definition
• Color Mode – refers to the types of colors you
will be using in you image
Types of color modes:
1. CMYK – Cyan, Magenta, Yellow, BlacK
- Setting of images that will be printed on paper
2. RGB – Red, Green, Blue
- color channel for the Web

35. Activity: Group yourselves into
