Searching photos by lens

->> I'm trying to do a search for photos that were taken with a specific lens...not having any luck with Bridge (CS5), PM (4.6.5), or Windows 7 Explorer. Problem seems to be that lens identifying info is stored in a really peculiar way (Opanda IExif reports the lens min/max focal length, max aperture as "18/1, 200/1, 35/10, 56/10" and of course trying various combinations of those values yielded no search hits either).
Any suggestions? |

->> Chuck,
Lightroom can do that in the Library mode. Under Library Filter at the top, click on Metadata and Lens should show up.

| ->> The ONE program I don't have...at least here. :) But I do have a copy of LR2 at the office, so maybe that will work. Thanks! |

->> You can do it PhotoMechanic. Neither method is completely elegant. You can change the sort parameters to {lens} and then select an image you think might be shot with the focal length you are looking for to check the metadata to confirm it.
A somewhat faster method would be to use the IPTC stationary pad and an empty IPTC field. Select all the photos in the given folder then open the Stationary Pad. Clear all existing data by clicking the clear field. Next, click the box for the Supp Cat 1 field and enter "{lens} mm" in the field (use a different field that you generally don't use if you happen to use this field) and then the apply to all button.
To find the focal length you are looking for, hit Ctrl-F. Deselect all of the fields except for the Supp Cat 1 field or whichever you used. Type in the desired focal length you are searching for. PM will highlight all the thumbnails with that number.
I would then tag them and hide all the remaining files to look for the specific image.
Hope this helps.... |

->> Before you freak out ....
...selecting the single box on the stationary pad only modifies that field and none of the other. Whatever data you had will remain intact.
- also, sorry for the crazy run-on sentence in the first graph :-( |

->> Manual technique:
Mac and PC:
Open an image shot with the given lens in Photoshop. Go to the file info, then go to the advanced tab. Expand "Schema (http://ns.adobe.com/exif/1.0/aux)" or (if the other isn't present) "Schema (http://ns.adobe.com/exif/1.0)". There's an entry that's something like this:
aux:Lens:EF17-40 f/4L USM
You want to copy enough of that to make it unique but leave out any special characters - so for this one I would copy "EF17-40" so there aren't any spaces or quotation marks, etc.
Then you can search for that text string inside of files in whatever folder. The EXIF info is stored in plaintext inside of JPEG and RAW files; we will now search for those plain text strings.
In OS X it's pretty easy - you just hit command-f in finder, tell it to search for whatever text in files in the current folder and then voila! You're done! You can also use "grep -R EF17-40 *" inside the appropriate folder from the command line.
Windows 7 will now be the bane of getting it done...
To make it index the text inside JPEG and RAW files (so you can search inside them), search for "indexing options" in the start menu. Click "advanced" then "file types"... Go down to "jpg", select "index properties and contents". Do the same for your raw file types (NEF, CR2, TIF, etc).
Then you can just go to the folder in explorer and type "17-40EF ext:jpg or nef" and it will find the files. |
