Guess the ISO
3

Not seldom photographer point out that a specific ISO value is the highest that can be accepted from a certain camera., due to image noise.

Well, here are som frames taken with my A7rIII. The 100% crops are presented in two coumns, and should be read column by column, from top to bottom.  Can you, just for fun, figure out this:

1) Guess the ISO value that was used
2) Figure out from these 100% crop what is the limit for you?
