In this project, I carried out an image editing task using digital tools to modify different visual elements. First, I changed the original sky in the image for a different one, creating a more eye-catching and attractive atmosphere. In addition, I added a duck into the scene, integrating it in a way that makes it look like part of the original image. With this edit, I practiced selection, cropping, and color adjustment techniques so that all the elements blended well and the final result looked natural and creative.

The people present in the image were removed in order to improve the visibility of the landscape and highlight its natural elements, resulting in a cleaner and more focused composition.

Problems

 41.- Think you want to print out a photograph with a size of DIN A4: 210 × 297 mm maintaining a printing quality of 200 dpi. Which resolution would the image need?

210 mm / 25.4 = 8.27 in

297 mm/25.4≈11.69 in

Step 2: Multiply by the desired dpi (200 dpi)

Width in pixels: 8.27×200≈1654 px

Height in pixels: 11.69×200≈2338 px

42.- Which resolution would the same picture need to have a 300 dpi picture?

Width: 8.27 in

Height: 11.69 in

Width in pixels: 8.27×300≈2481 px

Height in pixels: 11.69×300≈3507 px

 Required resolution at 300 dpi: 2481 × 3507 pixels

Description of second problem: Part 2º

 Using the same simple password for all accounts

Definition of the problem: 

Using the same password for every online account and application is a common but risky practice. It means that if one account is hacked, all others using the same password can also be compromised. Additionally, simple or short passwords are easy to guess or crack, making personal information vulnerable to cyberattacks and identity theft.

Five Good Tips to Avoid or Solve the Problem

1. Use unique passwords for each account:
   Never reuse the same password. This limits the damage if one account is hacked.

2. Create strong, complex passwords:
   Combine uppercase and lowercase letters, numbers, and symbols. Example: G!raffe_2025#

3. Use a password manager:
   Password managers (like Bitwarden, 1Password, or LastPass) can create and remember strong passwords for you.

4. Enable two-factor authentication (2FA):
   Add an extra layer of protection so that even if someone gets your password, they can’t access your account without the second verification step.

5. Change passwords regularly and avoid sharing them:Update passwords every few months, and never send them by message or email.
