Immerse yourself in the wonderful world of photography with Exposure Meter, the card game that teaches you photography while having fun!

The game is very simple: take the perfect photograph by adjusting the three key aspects of photography: Shutter Speed, Aperture, and ISO.

Contents. 63 exposure cards, 24 photography cards, 1 card with the QR code for the rules.
Goal of the game. Each player holds a virtual camera and must take the best-exposed photograph possible.
Introduction. For this game, knowing photographic techniques can be very helpful in speeding up the players' moves. However, these rules explain in detail how the game works, so it will still be possible to play, albeit more slowly.
In fact, thanks to this game, you will become familiar with photographic techniques as the games unfold. This game is therefore a very useful teaching tool for learning photographic techniques.
The cards. There are 4 types of cards: 24 image cards, each depicting a scene with the technical data for the shot (shutter speed, aperture, and ISO); 20 aperture cards; 20 shutter speed cards; 20 ISO cards (film sensitivity to light); 3 Joker cards with a value of 1, 2, or 3 stops.
A stop is the unit value used to indicate the reduction or increase in exposure. One stop more or less means a doubling or halving of the light hitting the film of our virtual camera.
The aperture cards have the following values ​​(from widest to smallest): 2.8 - 4 - 5.6 - 8 - 11 - 16.
As this number increases, the exposure decreases by 1 stop. A value of 4 is therefore one stop more open than 5.6 and one stop more closed than 2.8. The distance between the widest value (2.8) and the smallest (16) is 5 stops.
Shutter speed cards have the following values ​​(in seconds): 1 - 1/2 - 1/4 - 1/8 - 1/15 - 1/30 - 1/60 - 1/125 - 1/250 - 1/500. Each value differs from the previous or next value by one stop. 1/4 of a second is one stop more than 1/8 of a second and one stop less than 1/2 of a second. The distance between the longest shutter speed (1 second) and the shortest shutter speed (1/500) is 10 stops.
ISO cards have the following values: 1600 - 800 - 400 - 200 - 100. The larger number represents greater light sensitivity than the smaller number. ISO 800 is one stop brighter than ISO 400 and one stop darker than ISO 1600. The distance between the highest value (1600) and the lowest (100) is 5 stops.
The Wildcards have the following values: 1EV, 2EV, and 3EV, where EV stands for Exposure Value (better known as a stop). These cards can be used to decrease or increase the final exposure by 1, 2, or 3 stops. These cards can be used only if all three other types of cards are present.
A little technique: To take a photograph, you must have at least one aperture card, one shutter speed card, and one ISO card. Each reference image card shows the values ​​of each of these parameters with which that shot was actually taken. You must try to obtain that exposure or an equivalent exposure.
You can obtain the same exposure by taking cards with the same values ​​as those indicated in the reference image, but you can also obtain an equivalent exposure by balancing the aperture, shutter speed, and ISO values, knowing that as one of them increases, any other parameter must correspondingly decrease by the same amount. Suppose the card indicates the correct exposure with the following values: Aperture: 2.8; Shutter speed: 1/60 - ISO 1600. It is possible to obtain an equivalent exposure by using a card with an aperture of f/4 (1 stop smaller) and increasing the shutter speed by the same amount (1/30 instead of 1/60). This gives an equivalent exposure with the following values: Aperture: 4; Shutter speed: 1/30; ISO 1600.
As you can see, there are dozens of equivalent exposures, playing with all three parameters.
The game: Separate the image cards from the parameter cards and shuffle both decks.
Choose an image and place it face up in the center of the table. This will be the photo you want to obtain.
Deal four cards from the parameter card deck to each player. Place the remaining cards face down next to the image and reveal the top card opposite the reference photo. The player to the left of the dealer starts. Each player must perform the following actions:

Draw a face-down card or the last card face-up from the parameter deck.
Discard a card.

The first player to obtain the reference exposure or any equivalent exposure reveals their cards and declares that they have taken the shot. At this point, the round must be concluded to give all players an equal number of turns. If multiple players obtain an equivalent exposure, the yellow value on the reference card is checked. The player closest to that value wins. In the event of a tie, the next parameter (aperture or shutter speed) is selected. The player closest to the reference value wins.
In the event of a tie, the player with the lowest ISO value wins.
Then, another image card is chosen, all the parameter cards are shuffled, and a new game begins.
Additional Game Mode. You can also play somewhat like poker. The dealer deals five cards to each player, and in turn, each player can decide whether to replace one to four cards in an attempt to get as close as possible to the correct display. After completing the round of any replacements, each player chooses whether to play (and possibly pay a symbolic amount) or fold. At the end of this additional round, the player who gets closest to the correct display wins.
