This plugin is somewhat of like a stripped down version of ExposurePlot, but without the coolness, except that this
plugin integrates with your Lightroom catalog, which is sort of cool.
This plugin works in
(though some features may be missing in older versions of Lightroom).
The same download works for both Windows and Mac. See the box to the upper right for the download link (in orange) and installation instructions.
The plugin can plot the following photo parameters:
Focal Length — the focal lengths used, expressed in “35mm equivalent” terms
so that data can be compared and contrasted reasonably among different cameras with different crop
Extra data about the use of primes vs. zooms is also shown.
Shutter Speed — shown on a logarithmic scale
ISO — shown on a logarithmic scale
Ev — exposure value adjusted for ISO sensitivity as well. In Lr3+, any develop exposure adjustment is also taken into account.
To view a plot, select some images in the Library Module and invoke the desired plot via the
“File > Plugin Extras > ...” menu.
Tip: to work with all photos shown in the grid or filmstrip, select
none and the plugin will automatically work with all of them. This
is the same as selecting all except that selecting all suffers the side
effect that Lightroom tries to compute an updated metadata display, a
resource-intensive operation that can be easily avoided in this case.
(If you're into image metadata, also see my powerful Data Explorer
plugin, which lets you partition and group imgaes by different data-related criteria.)
You can save the plot data to a CSV file.
In Lr3+, you have the plugin create a collection of images that are represented
by a row in the plot, to isolate them for further inspection.
For a focal-length plot, The plugin also reports what percent of images were taken with a prime
lens, the extreme wide or tele ranges of a zoom, or beyond the range of the
lens (that is, a prime or zoom with a teleconverter). A focal length 1mm
within the end of the range is counted as the end, so with a 70-200mm zoom,
a shot at 70mm or 71mm is considered “most wide”, and at 199mm or 200mm,
“most tele”. (It may be interesting to combine this with the “Lens” metadata item in
the Library Grid filter, allowing you to generate the report on a per-lens
For a focal-length plot, you can have the number reported in terms of a
different kind of crop factor. This is useful, for example, when considering
lens recommendations for someone with a different kind of camera.
This plugin is distributed as “donationware”. I have chosen
to make it available for free — everyone can use it forever, without
cost of any kind — but unless registered, its functionality is
somewhat reduced after six weeks.
Registration is done via PayPal, and if you choose to register, it costs
the minimum 1-cent PayPal fee; any amount you'd like to add beyond PayPal's
sliding fees as a gift to me is completely optional, and completely
Note: a Lightroom major upgrade, such as
from Lr4 to Lr5, de-registers the plugin in the upgraded version, so if you
want to maintain registration, a new ($0.01 if you like) registration code
is needed in the upgraded version. It makes for a hassle every couple of
years, I know. Sorry. See this
note for details.

Update Log via RSS
Make the revalidation process smoother, especially for folks using Lr5.4 and later.
Fix a dialog-display bug in Windows.
Wow, I'd really screwed up the calculations for the "Total Exposure (camera Ev)" and "Total Effective Exposure (effective camera Ev)" items.
In both cases I had the sense of adjustment for ISO speed backwards, and in the latter case I had the sense of adjustment for the
Lightroom develop setting backwards, and in some cases could use the wrong number to begin with. Doh!
Found that with certain settings some math errors would pop up.
Oops, fix a bug introduced in the previous update
Added a bunch of cameras to the crop-factor database.
Added a few more cameras to the crop-factor database.
Added Canon 650D to the camera sensor-crop database
Added a bunch of data to the crop-factor database
Corrected the crop-factor data for the Canon Powershot G1 X.
Added crop data for a bunch of Ricoh cameras, some Canon, and another Fujifilm.
Added some crop-factor data for a bunch of Fujifilm cameras
Apparently, a recent change broke things on Lr2, which some folks apparently still use.
Added some Ricoh cameras to the crop-factor database.
Added a bunch of Canon cameras to the crop-factor database.
Fix an "attempt to perform arithmetic on field" error.
Update to handle the Mac App Store version of Lightroom.
Tweak for Lr4.1RC2.
Added some recent Canon SLRs. It's unfortunate that I have to do this, since there's a perfectly good Exif field for them to
indicate the 35mm-equiv focal length, but Canon doesn't use it. Sigh.
Enhanced the send-log dialog to hopefully make reports more meaningful to me, yielding, I hope, the ability to respond more
sensibly to more reports.
Added a bunch of Canon compacts to the database, and fixed a few that had been incorrect.
Had broken registrations in Lr2; Update to the debug logging to better track down timing issues that might arise.
Added the ability to save the raw data to a CSV file, in addition to the ability to save the summary data that was already there.
Added a few more cameras to the crop-factor database.
Fixed the data saved to the CSV file for ISO and shutter speed; it had been saving the log of the actual value instead of the actual value.
The plugin was neglecting to report when images had a focal length encoded in the metadata, but couldn't
be plotted because the plugin couldn't figure out the 35mm-equivalent. In these situations now the plugin
is clear about what's happening. I also added a bunch of crop-factor data for recent Fujifilm cameras.
Added some extra debug logging to try to track down an issue.
Fixed a bug that at times caused the focal-length labels to be incorrect, citing a random lens within
the actual range as one of the endpoints of the range.
More on the march toward Lr4, including upheaval in the code to handle Lightroom APIs being discontinued in Lr4.
Update for Lr4 beta: explain in the plugin manager that the plugin can't be registered in the beta.
Had issues with the registration button sometimes not showing.
Added a system-clock check and reports to the user if the system clock is more than a minute out of
date. An incorrect system clock can cause problems with various kinds of communication and authentication
with some of my plugins, so I've just gone ahead and added this to every plugin.
When doing a plugin upgrade, offer the ability to flush all the old copies of the plugin.
More updates to the internal crop-factor database. I really need to figure out a way to crowdsource this data.
A few updates to the internal crop-factor database.
Had an issue in the previous update with photos getting dropped.
Rewrote all the internals, and in addition to the ability to plot focal lengths, you can now plot
apertures, shutter speeds, ISO values, and Ev. In Lr3 and later, Ev includes
any adjustments made to the "Exposure" slider in Develop mode.
Updated the internal crop-factor database for the Fuji X100, which doesn't seem to include its crop factor
in its metadata.
Made the revalidation process much simpler, doing away with the silly need for a revalidation file.
Assume any camera-model Exif with 'scan' in it is from a film/slide scanner, and treat as a full-frame size.
Discovered a bug in my plugin build system that caused horribly difficult-to-track-down errors in one plugin,
so am pushing out rebuilt versions of all plugins just in case.
Added code to allow plugin revalidation after having been locked due to a bad Lightroom serial number.
Discovered a nasty build bug; pushing a new version in case it affects this plugin.
Oops, some of the new Lr3 collection stuff wasn't working... should be now.
This version can be registered in
Lightroom 3. It can run in Lightroom 2 or Lightroom 3; it does not work in the Lr3 betas.
It uses my new registration system when run on Lightroom 3,
which avoids some of the silly issues of the old one. Please take care to note
the details on the registration
page: use of this version (or later) of the plugin in Lightroom 3 requires a new
registration code, even if you had registered some older version of the plugin.
Added support for the Canon 550D/KissX4/T2i, which for some reason doesn't include
the 35mm-equivalent focal length in its metadata
Wholesale changes that attempt to honor the user's locale settings for numeric display (e.g. Europeans writing
3,14156 for pi). I've probably missed some spots, so let me know if you find some.
Minor UI tweaks on Mac.
Completely changed how the one-click upgrade applies the newly-downloaded zip file, in the hopes that
it'll work for more people. Rather than unzipping over the old copy, it now unzips to a temporary folder,
then moves the old folder out of the way and the new folder into place. Prior versions' folders are now
maintained (with the version number in the folder) in case you want to revert a version; you may want to
clear them out from time to time. Of course, it won't take affect until you try to upgrade after
having upgraded to or beyond this version.
Added a bunch of standard sensor sizes to the "view in terms of" list, so you're not
limited to the view of just the cameras you already have.
Added the ability to save the raw data to a CSV file, and the ability in the dialog
to view the focal lengths in terms of any of the cameras used.
Doubled the size of the crop-factor database thanks to a library of images
provided by exiftool
author Phil Harvey.
Well, I didn't realize that some camera makers (e.g. Canon) don't populate the
FocalLengthIn35mmFilm metadata item, so I built a database of camera
crop factors (currently: 678 cameras) to compute the 35mm- equiv focal length
