Focus Points

A plugin for Lightroom (on Mac) to show which focus point was active when the picture was taken.

Supported Cameras

Canon cameras with support for AF-Points position and size from the Exif fields when possible
Nikon D7200
Nikon D800
Fuji cameras with support for face recognition when possible - Should work with all recent X bodies (X-T2, X-T1, X-T10, X-Pro2, X-Pro1, X-A3, X-A2, X-A1, X-A10, X-E2S, X-E2, X-E1, X100T, X30, X70, etc)
Olympus cameras where 'AF Point Selected' appears in Metadata (Should work on recent E-* bodies)

Installing

Use the green button in this webpage called "Clone or download".
Extract the zip and (optionally) rename the folder from "focuspoints.lrdevplugin" to "focuspoints.lrplugin"
Move this folder to where you'd normally kept your Lightroom plugins.
Open Lightroom and go to File -> Plug-in Manager. Then click the "Add" button and select the folder
Once installed, in Library mode with a photo selected go to "Library -> Plug-in Extras -> Focus Point"

Supported AF-Points

Currently, 5 types of AF-points will be displayed :

The AF-Point is selected and in focus
The AF-Point is selected
The AF-Point is in focus
The AF-Point is inactive
A face was detected by the camera at this position

Please note that not all cameras save the needed information in the Exifs of the photo. Thus, the accuracy of the displayed points will greatly depend on whether or not your camera supports it.

Adding your own camera

If you wish to contribute, this should be as painless as possible. You will need to map all of your camera's focus points to pixel coordinates. Refer to the "focus_points/nikon corporation/nikon d7200.txt" as an example.

-- 1st column
B1 = {810, 1550}
C1 = {810, 1865}
D1 = {810, 2210}

-- an so on

The best way I found to do this was to set up a ruler/tape measure, get out my camera and I took a photo at each of the focus points lining it up exactly with the 1-inch mark. I then imported those pictures into Lightroom and ran this plugin so I could see the metadata. From the metadata, I could see the focus points name. I then took the image into photoshop and measured from the top left corner of the image to the center of the focus point. I compared the preview from the camera to my photoshop selection and got as close as possible. Once you have done all of that, add the file to "focus_points/{camera_maker}/{camera_model}.txt" using all lowercase. Then all is done.

If 2 or more cameras share a common points mapping, then PointsRendererFactory will need to be updated to know this. For example, the D7200 and D7100 could share a common focus points map (I don't know). If they do, PointsRendererFactory can be updated in code. I would prefer not see copying and pasting of focus point files such as "nikon d7200.txt" and "nikon d7100.txt" containing the exact same info.

If adding a camera which does not needed mapped because the focus point is given dynamically (like Fuji) or is a pattern (like A7Rii), create a new {ModelName}Delegate.getDefaultAfPoints(photo, metaData) for the camera and dynamically return the correct x,y point for the selected autofocus. Update PointsRendererFactory to set this delegate method on the Renderer.

Known Issues

Not currently working on Windows.
Lightroom has a bug where lrPhoto:getDevelopSettings()["Orientation"] always returns nil. Lightroom does not track if you have rotated the photo in development. As such, if the photo was rotated, the focus point could be wrong. The code attempts to resolve this, but it's only an attempt.
Not compatible if photo was edited in Photoshop. If the photo has been edited in Photoshop, the metadata in the photo telling the focus point was deleted. Perhaps in the future I can update the code to look for the original file and get the focus point from that.

TODOs

check for "normal" to make sure the width is bigger than the height. if not, prompt the user to ask which way the photo was rotated
show ExifTool license in plugin
