+.07 didn’t make sense to me, so I walked across the street to a bookstore and took a look. It’s actually +.7, which makes a bit more sense. I’m not 100% certain of this answer, but it’s my best guess.

Back in the days of film, it was not uncommon to “push process” film, which basically means increasing the exposure when it’s developed. Though it’s not exactly the same, the Photoshop equivalent would be to take the exposure slider and move it to the right.

I believe that in this context, +.7 means that he increased the exposure by .7 stop in post-processing.

The photographer also said that he used +.07 stop exposure. Is he/she saying that they added a +.07 f/stop, aperture, to the exposure, or does this have to do with some other setting, and how do you get just a .0 anything setting?

The issue is Winter 2008/2009 page 26.

Thanks,

Steven

They actually mean something. In short, it’s the ratio of the focal length of the lens to the size of the opening. There’s a really good discussion of this in the Wikipedia entry on Aperture.

Is f/8 just wider than f/11, or is there some mathematical magic?
