Guess the ISO!
About the photo
I left my house around 12 am, picked up a friend and we headed out to the north end of the Great Salt Lake to capture the rising milky way. This photo is taken from a large rock outcropping that gives a nice view to the Great Salt Lake (which is fairly dried up as you can tell, all the foreground used to be filled with water)
I was testing out a new term that I'd heard, ISO invariance, so I was shooting with various ISO's to see if there was much difference in the final result, surprisingly no, not much at all. I think this will make guessing a bit tougher.

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 ISO setting that was used to take the photo. For example, you might guess “100”, or “800”. .
- Only one guess per person, per post.
- No editing your guess - you have to commit!
- 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!)
- For this game you have until Wednesday at 11:59PM MST
- Scoring: Is done using Hive Tips on your responses.
My scoring will be:
I've got 30 HIVE total to give away for this one, the 1st person to guess correctly (or closest) will get 15 HIVE, 2nd 10 HIVE, 3rd 5 HIVE. If only person gets the correct answer they get all 30 HIVE, If only two people get it correct, the 1st will get 20, and the second will get 10.
