Guess the Shutter Speed, the Focal Length, the Aperture and the ISO of this image!
This cute New Zealand seal chose me as his target on the beach and at first tried to actively make friends with me — got out of the water, purposefully walked towards me, for some time he was curiously examining and sniffing me from all sides, and later he happily posed for me near the water. These were several unforgettable minutes: such a rather big animal spins around me and either tries to bite, or wants to play, who knows :)
What is Shutter Speed?
Shutter speed is the length of time the camera shutter is open, exposing light onto the camera sensor. Essentially, it’s how long your camera spends taking a photo.
A fast shutter speed is typically whatever it takes to freeze action. If you are photographing birds, that may be 1/1000th second or faster. Long shutter speeds are typically above 1 second – at which point, you will need to use a tripod to get sharp images. You would use long shutter speeds for certain types of low-light / night photography, or to capture movement intentionally.
For more information and examples see Introduction to Shutter Speed in Photography
What is Focal Length?
Focal length describes the angle of view of a lens. That is, how much of a scene before us the lens captures. And in addition, how large subjects within the frame appear. The longer the focal length of a lens, the narrower its angle of view.
What is important to remember is that lenses with long focal lengths bring objects closer, like a telescope. And, on the flip side, wide angle lenses are great for capturing large vistas.

What is Aperture?
Aperture can be defined as the opening in a lens through which light passes to enter the camera. It is an easy concept to understand if you just think about how your eyes work. As you move between bright and dark environments, the iris in your eyes either expands or shrinks, controlling the size of your pupil.
f-stops are a way of describing the size of the aperture for a particular photo. For example, f/2.8 is larger than f/4 and much larger than f/11.
For more information, examples and videos see Understanding Aperture in Photography NOTE: Some cameras such as cell phones have very atypical numbering for aperture.
What is ISO?
In very basic terms, ISO is simply a camera setting that will brighten or darken a photo. As you increase your ISO number, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments, or be more flexible about your aperture and shutter speed settings.
However, raising your ISO has consequences. A photo taken at too high of an ISO will show a lot of grain, also known as noise, and might not be usable. So, brightening a photo via ISO is always a trade-off. You should only raise your ISO when you are unable to brighten the photo via shutter speed or aperture instead.

RULES & HOW TO PLAY
- For this Metadata Monday I would like you to guess the the shutter speed, the focal length, the aperture and the ISO of the photo. Speaking of focal length, I mean 35mm equivalent focal length (or effective focal length), as if we are using a full frame camera.
- Only one guess per person, per post.
- No editing your guess - you have to commit!
- All metadata has been stripped from the pictures, so don’t bother looking for the EXIF!
- We are not required to tell you what kind of camera was used, or what time of day the photo was taken at, or whether filters were involved (this adds to the mystery and the challenge!)
- Submissions are due by: Wednesday 10-00 UTC
I will be giving HIVE TIPS to winners which will translate to PhotoGames points on the Leaderboard
