DIGITAL PHOTOGRAPHY AND IMAGING - Week 5

WEEK 5 ( 14 / 05 / 2020 )

Lectures : 

- Exposure : Shutter speed, Aperture and ISO.
is the act of exposing the image sensor to light. By adjusting the amount of light, you can make a photograph of a bright sunlit scene look dark, or a shot of a dark interior look bright.

- Shutter speed is a measurement of the time the shutter is open, shown in seconds or fractions of a second: 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s, etc. The shorter the time the image sensor is exposed to light, the darker the resulting photograph.

- Aperture (expressed as an f-number) controls the brightness of the image that passes through the lens and falls on the image sensor. The higher the f-number, the darker the image projected on the image sensor.

- ISO is a camera setting that increases or lowers the amount of light in a photograph. It’s always best to take advantage of all the natural light you can get your lens on, but sometimes darker conditions call for a higher ISO.

Practical :

Exercise 5
- Class Practice :

Displacement map hybrid animal ( part 1 )


Healing tool set

Creating hybrid animal with displacement map ( part 2 ). 

Select a photo of animal online, as well as a photo of fur/skin from different animal. Apply the new coat to the chosen animal. 

Animal photo: 

1. Apply black & white filter, 

2. Apply Gaussian blur, 

3. Save as displacement map PSD file,

4. Reopen the jpeg/ png photo (NOT the PSD file). 

Fur/skin photo 

5. Move it to the animal photo, 

6. Free transform to resize & rotate, 

7. Convert to smart object, 8. Apply displacement map, 

9. Choose blending mode 

10. Masking 

I chose a dog and a zebra skin from online for the exercise.

animal ; dog

skin ; zebra

After matching those photo, I chose the outcome that shows out the best combination.

first outcome

After getting feedback from lecturer, I do some minor changes for the texture to make it works better.
