Why are there 12 image options when exporting a JPEG?

[lassep34521165]

If you use safe for web you get the options low,medium, high, very high, maximum and a scale from 0-100, regarding jpeg quality.

here;

low = 0 (10) - 29

Medium = 30-59

High  = 60 -79

Very high = 80-99

Maximum = 100

But if you safe as a jpeg (using safe as) you get 12 steps...

0-4 = low

5-7 = medium

8-9 = high

10-12 = maximum

But why???

Save for Web has been deprecated in recent versions of Photoshop.

Here is an article that addresses this question, including a conversion table between the two different methods. The focus is on Photoshop Save as vs Lightroom, but this applies to Save for Web as well, and if you keep reading, you will get there.
