This is a great challenge! In order to prepare the game “find 15 differences”, I first need to create two images that will be almost identical, but will differ in these 15 details.

I have come up with a scene for you: A busy street in a historic European city full of people and details.

First, I will generate the first, “original” image. Immediately after that, I will generate the second image, which will contain those 15 changes. Then it will be up to you to find them!

Here is the first, basic image:

Great, the first image (original) is ready!

It shows a busy historic street with a “CAFE LUNA” cafe, a bakery and many people.

Now I am going to create a second image, which will look exactly the same, but will contain exactly 15 small changes. Once I generate it, I’ll show both images side by side so you can start searching.

Here are the changes I’ll make to the second image:

Change the text on the gate sign to “ST.PETER’S GATE”.
Remove the striped awning above “CAFE LUNA”.
Change the color of the woman’s coat to blue.
Change the sign “BAKERY DELIGHT” to “FRESH BREADCO”.
Change the tram number from 12 to 24.

Change the color of the blue door on the right to red.
The man on the bench is no longer reading a newspaper, but is holding a tablet.
The flower pot disappears from one of the balconies above the cafe.
Remove the wicker basket from the bicycle.

Change the color of the woman’s canvas bag to yellow.
Add a small, sleeping dog under the bench.
Change the color of one of the overhead flags to deep purple.
Change the sign “ART GALLERY” to “PHOTO STUDIO”.

Adding a little bird sitting on a lantern.
Changing the word “BOOKSHOP” to “LIBRARY”.
I’m going for it!
