It took me forever to find it… one single vowel mistyped in a variable name made all the difference. I just pushed a version that should work. Thanks for the report. —Jeffrey

It works!

… but …

It turns out it processes the photos in the grid, and throws an error: “no photos had 35mm-equiv focal-length data” … when the images are shot with a Canon 60D

Any information you need to add this camera to your crop table?

Just pushed a new version that should handle your 60D shots. —Jeffrey

Thanks and greetings from Germany, keep up your great work,

Oops, I pushed out a version with this three months ago, but neglected to let you know, sorry. It’s there now. —Jeffrey

If you tried writing a plugin using the limited API that Adobe provides, you’d see how it can be so slow. —Jeffrey

A terrific adjunct would be a similar plot of orientation (ie, vertical/portrait, horizontal/landscape, square)!

Just one question: does it also works with RAW anf TIF files, or only with JPG (like ExposurePlot) ?

TIA to let me know…

It works with your Lightroom catalog, so if Lightroom knows the focal length, so does the plugin. —Jeffrey

I’m triing out your data-plot plugin but when I check my Panasonic FZ30 pictures I see in the dropdown more than 1 entry for the FZ30 with different crop factors (4,9 – 5 – 5,1 – 7,5).

The FZ30 has a lens of 7,4-88,8 mm wich is equivalent to 35-420 mm so the cropfactor is 4,73 (4,729729729729… to be more precise)

Now you can choose a lower resolution where the FZ30 only uses the center of the sensor and so seems to have a bigger cropfactor but that is in reality only a crop of the bigger picture so (in my opinion) nothing to use in your calculations.

You say you use a database of camera’s to calculate the 35mm equivalent but I suppose that it is buildin the plugin and that the user has no acces to it to add/remove entries?

Many thanks in advance,

If it were using only part of the sensor for the smaller images, it would be a bigger crop, but it’s downsizing from the full sensor to create the smaller image, and hence the crop factor is the same, but gets calculated incorrectly, which is the real problem you’re reporting. The problem is that the plugin can’t tell the difference between an image that’s been cropped, and an image that’s just smaller out of camera. I suppose it makes sense to assume it’s smaller out of camera and let it be wrong if it’s been cropped before loading into LR… I’ll look to see whether I can do that. —Jeffrey

I first tried doing a “Screen Print”, but all I got was the background of LR2, not the Data Plot (it’s really labeled “Jeffrey’s Focal-Lenght Plot”). Not sure why this happens. Press Print SCRN and the Data Plot panel vanishes, “click”, the screen print happens, the data plot comes back on top. What gets saved is the LR2 panel.

In playing around for a day or so and looking at what I wanted out of it I found, at least for me, some “Nice to Have” ideas for the way I did my graphs. Yes, I realize “Easier Said Than Done”…

I do the Data Plot then do a Save Data to generate the CSVs. Then on to Excel (since I could not print screen it).

First thing I had to do was delete the blank lines after I opened the CSV in Excel (2000). Would be nice if the blank lines were not there.

Then I converted the StartMM and EndMM to the normal lens values. Just divided the values by 1.5 because the output of Save Data converts (or uses) 35mm equivelent. Know you are working on this. Great if it was the same choices as on the screen plot.

Then I created a new column of data that was a Range in mm, using the StartMM and EndMM converted data. Just like on the Data Plot. Would be nice if you had a column in the CSV giving range.

I would like to see nice rounded values in the StartMM EndMM and RangeMM areas. Values in multiples of 5, 10, 25, etc. Nice round numbers. Currently you might have a value of 189 or 193. How about these falling in a 185-200 range. I had lots of odd ball numbers on my plots. This would be a “Nice to Have” but most likely is a “Easier Said Than Done” item.

Thanks again for neat programs. Not to mention a neat website.

Using this in combination with built in LR filters really helps me understand which lenses produce the most pleasing shots.
