Ive change the composition of the main focus of the image by moving the main subject out of dead center, then adding Clouds and Noise to finish the look of the image.

*Change the orientation by making a horizontal aspect image into a vertical aspect image (or vice-versa)

Change the orientation of the image from a horizontal aspect image into a vertical aspect image.

*Change the compostion so it adheres to the “Rule of Thirds”

Ive change the perspective of this image, to highlight the logo as well as the camera on the BlackBerry Passport.

Learning Task 2 | Understanding Resolution

 

1) Define pixel, dpi and ppi:

A Pixel is a physical Dot of illumination on a display screen, dpi means Dots per inch, which is a measure of physical points placed in a line within the span of 1 inch, while PPI means Producer Price Index a group of indexes that measures the average movement in prices by domestic producers of goods and services over time.

Sources: Problem, i already had a in-depth knowledge of pixel, dpi and ppi due to my business and my hobbies and didn’t need any sources. 

2) What’s the typical resolution of the latest orbiting “spy” or “keyhole” satellite (what’s the size of the smallest object it can detect ):

Although not the latest orbiting “spy” or “keyhole” satellite, The “Keyhole-class” (KH) reconnaissance satellites, the KH-12 has a resolution of 5-6 inches, which means they can see something 5 inches or larger from the ground.

Although are rumours that the newer orbiting “spy” or “keyhole” satellite have a significant higher resolution and can see something up to less than 1 inches or larger from the ground, it remains proven.

3) What sort of resolution ( dpi ) typically would your images need to be at for high-quality glossy print publications ?


typically for a glossy print you would need a dpi of 300 to 400 dpi. But For high quality commercial print your image resolution will need to be as high as 600 dpi.

4)What sort of dpi do your images need to be for the web?

Its believed that 72 dpi is ideal for the web.

5)What’s the maximum image size of your digital camera (width and height in pixels) ?

3264×2448 pixels

Sources: None

6) Why is it important to capture as many pixels as you can?

The more pixels you have, the more light that can be collected resulting in a more detailed and sharper image.

7) Why is it “bad” to resize images bigger (describe what happens to the image) ?

It’s acceptable to scale images down in size; the quality of the image isn’t compromised, however depending on how many pixels you had in the first place, scaling the images up to high can causes a loss of detail, this happens because the original pixel information is now spread across a greater number of new pixels.

8) You’re a designer and you need to supply your client with an original photo that stretches across half a 15m wide billboard. Describe how you would ensure the final result is optimum quality.

To ensure the optimum equality is kept, you would use the highest resolution available to you.

Note: I am at somewhat at a lost with this question, if you could please provide me with where i could find the answer, it would be appreciated

9) When is a pixel not “square” ?

Commonly you will find Pixels that are not square on images that must be compatible with standard-definition television motion pictures for example, These pixels are not “square” but “rectangular” (the pixel width and height are different).

10: In your own words, describe what the “Resample Image:” option in Photoshop does

The “Resample Image” option in Photoshop enables an image to be resampled once you added more pixels or change the size of the width/height, if turned off, it will no longer Resample the Image size instead by for example increasing the pixel count in the image, when printed the image size will shrink to account for all the new pixels.
