Photomontage

 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.

 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)

Inkscape flags:

In this activity, we're going to learn how to use a new application called Inkscape, where we can create and edit drawings or photos. Specifically, in this activity, we're going to focus on learning how to draw flags of countries around the world. I had to draw the Swedish flag, the European flag, and the third one was optional. I chose the Romanian flag because my parents are Romanian, and Romania means a lot to me.

Activities 41 and 42

 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
