One problem, 3 ideas

[Mariusz Rutkiewicz]

Hello,

first of all, I'd like to thank you for your great job and effort in making this wonderfull piece of software.

As in title i've got one problem and 3 ideas.
Problems first ;)
I've installed your software on linux Mint, and made some tethered shots with Canon EOS 80D. Problem is I cannot set camera output to TFT + PC. They simply cannot work together and I cannot do anything about it. I've tried this on different flavors of linux, even with different camera (Canon 6D) and the result is still the same. Tests were made on camera - laptop usb connection, wi-fi is not an option for me ;)

About the ideas wchich I'd love to see on te newest version of Entangle.

1. Ability to rotate screen during tethered live wiev shooting. Quite often I make vertical shots and usually it's neck-breaking expirience as screen rotates with camera. I've seen this option on Darktable while tethered shooting, but it's abilities are no longer developed. It's also written in open code so maybe it would help ;P

2. Option to zoom in or out during tethered live wiev shooting. It really helps to focus on details.

3. Ability to click, set or at least see camera focus point during live wiev.

That's about it, and tkank you once again for your grat job and dedication to this project.

Sorry, I'm not sure what you mean by "TFT" here ?

Yeah, that's not the first time this is requested. Normally we honour the
exif rotation info, but I don't believe live view includes that. Even if
it is present, cameras sometimes get confused & set wrong rotation if you
have them in funny positions. So a manual override of rotation would be
useful in live view & normal view.

IIUC, Canon has a way to zoom during live view. In theory that's doable
but I'm not entirely sure how.

This is very hard. gphoto exposes a setting for the focus point, but
the focus points are merely plain numbers 1 -> n... There's no info
about what physical (x,y) position within the frame the focus point
has. This position info is of course different for every camera too :-(

This would have to be solved in libgphoto2 first. Likely someone will
need to figure out position info for many many cameras and record them
in a giant data table....

Regards,
Daniel

Hello and thank you for your fast response :)

Answering some of my topics:

"Sorry, I'm not sure what you mean by "TFT" here ? " 

I mean I cannot set live view on both camera display and Entangle tethering live view screen to work at the same time.

"So a manual override of rotation would be 
useful in live view & normal view. "

Yes, that's exactly what I need. I can manage photos rotation myself with exiftool, but in Entangle live view it would be great to manually adjust screen orientation.

If only those 2 points could be solved I would be super happy :)

That's not possible with any camera I've ever used, though my DSLR cameras
are all fairly old at this point.
