Pentax K-1 support

[musselwhizzle]

Awesome. Thanks. Would you mind attaching a raw file for me so I can see the metadata and play around with this? The code will most likely need some updates as I don't think "33" is a valid property type. I'll work on adding it for you though.

You can take any files from dpreviews studio scene comparison, such as this JPG here: https://www.dpreview.com/reviews/image-comparison/download-image?s3Key=6f225c8c22ca48c9bc25c582f9981382.jpg where the center point was chosen.

On Pentax DSLRs the AF points actually always are named by a simple number such as "1" or "5" or "33", where on Nikon you have the "A1" and "D8" and so on. The num,bering scheme also is quite simple on all models since they always start the "1" on the top row left corner and increment as you read to the right and down. See Phil Harveys documentation here: http://exiftool.sourceforge.net/TagNames/Pentax.html

On a more general note I suggest for a later release you consider a routine to adjust things if the used creates a JPG with a resolution lower than maximum, e.g. 16 MPx instead of 36 MPx. The absolute pixelcounting currently suggests it works only on uncropped full res images.

Thanks for your great work.

By the way, I got to the data in a quick way:

1. Google for a viewfinder overlay image for your camera, such as this one: https://1.bp.blogspot.com/-DRWu2YmqHcg/UeNOnX0OtjI/AAAAAAAABaU/68Oz7X-Svf0/s1600/Nikon+D7100+AF.jpg
2. Show it on your computer screen screen maximised
3. Take one JPG image of your computer screen with your camera where you frame it exactly fitting
4. Display your photo JPG in a viewer like XnView which does show the exact mouse pointer coordinates
5. just point the mouse over each AF point and take a note of this

until i have a chance to test it, you can take a look here and see if it works as expected.

Hm. I do get an error 1 as it says, the plug-in is for LR v6 only.
I only have LR v5.7.1 here.
Is the plug-in really dependend on v6 specific functionality? That might exclude quite a number of people from using it.

[musselwhizzle]

i lowered the required version to 5. download again and try. Let me know if the whole application still works. I only have LR 6 so I can't test.

[Knubbel]

Thanks. I now can start the plugin. But when calling it I get an error pop-up:
"Internal error. Couldn't open file [image]-metadata.txt for reading."
Running Windows 7 64bit if that has any impact.

[musselwhizzle]

Would you download this version which has logging enabled:
https://github.com/musselwhizzle/Focus-Points/tree/feature/windows_path

and paste the logs in here. According to the docs, the log is located in "your My Documents folder."

[Knubbel]

Thanks, I will run that in a minute. First I would like to share something I found on Adobe forums, which might be helpful here as it is about funny LR Lua syntax:

on Windows systems, LrTasks.excecute() is tricky:

• substitute \ by \\ (this is a Lua issue)
• surround each pathname that has a space in it with double-quotes (")
• substitute > by ^>
• in addition, surround the whole commandline with double-quotes

Besides that your program path doesn't look correct. It should be:
C:\programs\dcrawps64.exe
and therefore in your Lua code, you have to use:
C:\\programs\\dcrawps64.exe

The only log file I found after installing your new version is "libraryLogger.log" and it contains three lines:

01/05/2017 11:27:13 WARN starting plugin

No file of the name "K_1_1502-metadata.txt" is on the drive.

[musselwhizzle]

Ok thank you. Some people are working on the issue over here on this ticket. #11 (comment)

I'm confident it'll be figured out soon :)

[Knubbel]

Cool. Just give a message, once that is solved.

[musselwhizzle]

windows is kind of resolved-ish. It's the best it's going to get for now (which is no good....)
If you're able to verify the plugin at least attempts to put the focus spots in the right place, that would be great.
