Ercilla Museum
In this project, I learned how to make a "museum" of a normal photo:

Photomontage
In this project I learned how to change the color in a picture in black and white, but mantaining the principal color of one object.
Here I´m going to put a explication to known how I do it:
First, I opened the original photograph of the cat in the tree. Then I duplicated the layer to work with two versions of the same image: one that would retain the color and another that would be converted to black and white. I desaturated the bottom layer by going to Colors → Desaturate, choosing the option that best preserved the contrast. This made the background black and white.
Next, on the top layer (the one that retained the color), I added a layer mask. I used a soft brush to paint the mask black, covering the entire background and leaving only the cat's body unpainted. This way, the cat remained in color while the rest of the image displayed the black and white layer below.
Once I had finished defining the edges and made sure that only the cat was in color, I added the text. In the upper left corner, I wrote the date “10/02/2026”, and in the lower right corner, I added my name, “Samuel Grosu Olar”. I adjusted the size and color of both texts to white so they would be visible but discreet.
Finally, I saved the file in .xcf format to preserve the layers, and exported the final image in JPG format, as requested.
BEFORE:
GIMP (VOLCANO LANDSCAPE)
In this project I learned how to remove the sky from an image using GIMP, replace it with another one, and add some animals.
In the picture i aploded two eagles in the sky and two cheetah in the beach (One at the bottom right and the other at the top left)

activitie 41:
♣ 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?
Required resolution for A4 at 200 dpi
Step 1: Convert A4 size from mm to inches
1 inch = 25.4 mm
Width:
210/25.4 = 8.2677 in
Height:
297/25.4 = 11.6929 in
Step 2: Multiply each inch value by 200 dpi
Width:
8.2677 * 200 = 1653.5
Height:
11.6929 * 200 = 2338.6
Step 3: Round to whole pixels
→ Required resolution: 1654 × 2339 pixels
activitie 42:
♣ 42.- Which resolution would the same picture need to have a 300 dpi picture
Required resolution for A4 at 300 dpi
Step 1: Convert A4 size from mm to inches
(Same as 41)
Width: 8.2677 in
Height: 11.6929 in
Step 2: Multiply each inch value by 300 dpi
Width:
8.2677 \times 300 = 2480.3
Height:
11.6929 \times 300 = 3507.9
Step 3: Round to whole pixels
→ Required resolution: 2480 × 3508 pixels
