Displaying Focus Points

Hello, I was wondering if the ability to display focus points is buried in PL somewhere or on the to do list.
After taking over a 1000 photo’s on a recent holiday, mostly of fast moving and small birds, I need to quickly cull out photo’s where my camera missed focus. Being able to quickly see if the focus point was on the bird or the branch behind the bird or missed completely, would be very very helpful.

Thanks
Aaron

Unless your image is very static and you didn’t recompose you can’t rely on that info. Special not in fast moving birds.

Hello George, thanks for the reply. The benefit for me is purely in the culling stage. Rather than having to load and zoom into each of the photos to check where the focal plane ended up being, (typically desired on the eye of the bird,) if the focus point square is not on the eye of the bird, or very near it, I can immediately mark the photo in PL to discard and move on. Any small improvement to speed up the work flow, is appreciated and adds up over thousands of photos. The data is definitely contained in the raw file as Canons own software(free) can display what the chosen focus point was. Hopefully it’s on there to do list.

Kind regards

Aaron

Hello,
I’ve voted for Focus points and we have discussed it also in Displaying AF Point, and it would be nice if it would give a function like in the Nikon Capture software.
A few month’s ago I’ve got photos from my nephew taken with Nikon equipment, an he was asking me why the photos aren’t sahrp. No chance in DXO to see where the focus point was by taking the photo.
So I have to install Capture NX-D to got this information.
So I understand the request by azkaz

Best regards

The problem with focus info in exif data is the not all cameras provide it and, when they do, it can be quite confusing. See this page from Phil Harvey’s excellent ExifTool documentation for the Nikon.

Even using Nikon’s own NX-D software, if nothing is in focus, it doesn’t show which point was being used to attempt to focus.

I prefer actual focal plane info (already in DxO’s backlog) vs. knowing the camera’s focus points before the shutter was pressed, which after a recompose or a focusing error won’t tell me what’s in sharpest focus.

I would also like the ability to see the focus point. Doesn’t have to universal if some exif from cameras doesn’t support it.

If the query is about Sony read below. Focus points can be shown within Lightroom for Canon and Nikon using some kind of link with Harvey’s EXIFTool; and I expect somewhere that a standalone program is available.

There’s a standalone version providing a graphic called A7info.exe which works for 7 & 9 bodies.

There’s another standalone that relies on Harvey’s EXIFtool. It takes a little time to decode the installation instructions.

With birds you’ll find the point of focus can be all over the place when working in AF-C mode.

I think the value of seeing the focus points is overestimated. They’re wrong when recomposing after focusing but can also be wrong when using af-c.

You can expect that when in CAF the body attempts prediction and the point of focus recorded in EXIF can therefore be off the subject. If both are in the same plane of focus, or near enough, that’s not an issue.
With mirrorless cameras and AF points that cover most of the sensor, focus and recompose isn’t much needed any more.
There’s still great value in studying the point of focus over a series of burst shots to check for accuracy and speed of focus adjustment. And in some cases of static shots, the much-vaunted Sony A9 (and the A7R III) will shoot without a point in focus and give you a blurry subject and sharpish background. That perplexes a lot of users, me included, and a program like A7Info helps get some kind of handle on it.

Your comment above piqued my interest, Ziggy … I guess it’s directed at Sony a7 cameras(?)
I found reference to this tool here - which led to a download site here.

I haven’t downloaded/tried it yet - Can you please tell us a bit more about it … Is the interface in English ?

The program is in German but that barely matters.

If you open the website in Chrome it’ll offer to translate the page for you.

A7info is for A7 and A9 cameras. The latest version does jpegs and raw.
The other program I mentioned covers more Sony bodies but only jpegs. It shows face AF points for some bodies.

Thanks for this tip, Ziggy … It’s a handy little utility (for perusing EXIF data from Sony RAW/ARW files).

Hy,
Why are focuspoints it self that interresant?

I understand edge detection, general focus aka sharpnes. Shows the DoF.
I understand detail detection. A sort of fine edgedetection. Showes the focus area.
But camera’s focus ponits are only relayable if you took it steady as in trypod.
Small change in aiming after focus lock can fool your afterview of that.

A edge detection which you can alter how stricked,point of end of DoF will be for your preference and a detailed edge detection for the focalplane detection is rather my feature i like.

All those other forms of focus detection and indication would be great! Hopefully they come in time. For those with cameras that contain that information and for those who find it beneficial, grabbing and displaying focus points used would seem to be “low hanging fruit”. Simply displaying existing information contained in the image data. No programming required, no processing required, no slow down to displaying the image etc.

Maybe you can try FastRawViewer for culling. They have such function (Check In-Focus Areas and Noise in Shadows). I have no expericence with it.

Hi Jon, thanks for the suggestion! I actually do have FastRaw Viewer and it is excellent! I would definitely recommend it. It would be great to have the FR features in PL also!

Kind regards
