Way to determine which AF mode was used in a photo (e.g. zone, spot, ...)?

I am currently looking back at a bunch of photos and trying to determine which AF mode I used for a given set. I can see which focus points were used with Canon's DPP or Zoombrowser, but not which mode I was using (spot, single point, single point with expansion, or zone. Is this possible?

I don't know if cameras record that data or not. I do see the AF "Mode" recorded, such as AI Servo AF or AI Focus AF, but not the more advanced data like "Zone" or whatever.

It could depend on the camera and also your Exif reading software...

i think Aperture is one of the few programs out there that shows your focus points

like this: http://thedigitalstory​.com …show-focus-points-in.html (external link)

ExifTool (external link) used with ExifTool GUI for Windows (external link) will tell you the focus mode used and a ton of other useful information

So too will BreezeBrowser Pro, but BBPro is not free: http://www.breezesys.c​om/BreezeBrowser/ (external link)

Thanks for the help, guys. For clarity, I can already use the programs I have to see which AF points were used. I'm looking for a program that can identify the particular AF Mode used, as previously described.

ExifTool shows a lot of metadata but it doesn't show the AF Mode used.

Just to be clear:

"AF Mode" in general would refer to One Shot AF, AI Focus AF or AI Servo AF (or to an Auto mode). But that I think is different from what you are asking about?

If I understand, you are wanting to know about settings used by the 7D, the 1D bodies, and the 5D3, which give "expanded" modes like "zone", "point", etc. Am I correct?

Right. I know mode traditionally refers to AI, One Shot, etc., which is why I defined "mode" in the sense I'm referring to both in the title and in the first post. Maybe AF Point Selection Mode would be more fitting, but I thought it was pretty clear that I wasn't referring to whether it was in AI Servo/One Shot.

Heh! I thought it was apparent, I'm just not sure about everyone else!

Yea, no biggie. But, I think it's evident that there's not really any program that can identify this as I'm not sure it's actually recorded in the RAW file. That would certainly be something useful for Canon to start recording, I would think. For instance, I'm trying to do some correlation on missed focus versus AF Mode Point Selection for different situations.

There is another utility that shows loads of Exif info, including Canon "proprietary" info tucked into the "maker's notes" section.

It's called "PhotoME". I haven't used it since I installed Win7x64 so don't know if it will run and I don't have a link to it, but Goggle should bring it up!
