Focal Length Analysis

[Kayaker72]

I've heard several members mention analyzing a set of their photos to determine which focal lengths they use the most. I've always assumed that one of the versions of software does this for you automatically, but I can't find it.

Could you let me know how you do this?

Thanks in advance...Brant

I use Apple Aperture which lets me export some (not all) exif data of selected to a csv file using an AppleScript Automator Workflow. The rest is Excel.
I think there are also tools that scan image files directly, independent of Aperture, Lightroom or others, but I don't have a name ready.

Adobe Bridge will sort individual folders by focal length.

I use a little app called PhotoStats.

Typed in photostats and all that I am pulling up is a iPhone ap.

Hmmmm...I've had it for quite a while. It was freeware, probably on softpedia or something like that. The About popup is useless, and the Check for Updates is broken, so it's clearly not supported.

Still works, though! Useful for a quick graphical representation of bodies, lenses, focal lengths by lens, apertures by lens, etc.

I also have an 'analysis' folder of smart albums in Aperture, one album for each body, albums for each body + lens combo (for lenses where you use TCs, you have to add EXIF rules 'not 1.4x' and 'not 2x'). That's good for actually looking at the images in each bucket.

Thanks...I have DXO, Lightroom and DPP. I take it not of these have this feature?

In LR library module you can choose focal length as a filter parameter. If you select "all photographs" in the left panel and add a metadata filter with focal lenght as one of the filter parameters, you basically get your statistics in the drop down list. I don't know of any way to save the info to file, but for me this is good enough.

(In my list it's obvious that I mostly use the ends of my zooms. If I exclude the zoom ends and the primes, my most used focal length is 35 mm (on crop bodies).)

Additionally, if you place lens as superior filter parameter (to the left of focal length), you can also get the statistics for each lens (i.e. you can see how you use your zooms).

Well done next time I'll read the second page before answering... Sorry

With LR, you can probably do something with the filter window (\ in the lib module)
. Otherwise, there is certainly somebody who developed a plug-in for that.
