Each doubling of ISO is an f/stop: which way is the f/stop going, up or down ?

100 to 200 is one f/stop

200 to 400 is one f/stop

400 to 800 is one f/stop

800 to 1600 is one f/stop

1600 to 3200 is one f/stop

3200 to 6400 is one f/stop

and so on.

Oh, and as to a book, "Exposure Manual" by Dunne and Wakefield is a classic.

can you take this kind of portrait by simply adjusting your fstop??

Which way is the f stop going after the doubling of the ISO ? Up or down ?

Do you use a backdrop, if so is it sports oriented ? Where do you get your backdrop if you use one ?

Sigma 70 200mm f/2.8

I love my Sigma 70-200. I have the one with stabilization. I'm an amateur but the lens makes me look like a pro, because the pictures are so sharp it's scary
