So useful! Thank you very much!

exellent tutorial paul

What you have done with this video is to convinced me to stay 100% with C1!!! I didn’t realize why C1 doesn’t allow me to crop outside the image, but now I know there is the option! Thank you 3000! I’ll follow you forever

I never realise the amount 80%...and the 4 dots way of doing it. gosh. awesome, always something new to learn from your sharing. thanks

Even though I've used C1 for a while, I always learn something new from your videos.

Perfect lesson! Thank you very much! Good voice, clear and comprehensible. Nothing to improve.

I'm not really into architecture shooting but I could definitely apply this for landscape. Another great one for my KB and well explained.

Gee this was hugely helpful! You really explained the entire tool and how to deal with those sticky situations where things cannot be completely corrected. Thanks so much for these videos!

Thanks a lot for your thorough and detailed explanation. Such an amazing walkthrough and practical examples. This really cleared things for me with perspective corrections with capture one. Amazing night photography and cityscape 👏🏼👍🏼

Thank you Paul. You should have become a teacher 😊. Your explanations are concise and very clear. It is a pleasure to listen to you !!. It would be great if the "Guides" could be not only vertical and horizontal for when you don't have a reference in both sides (like in the case of the church). It might be used as a "keystone reference line" when nedded.

Thanks Paul. Hugely valuable as always. On the amount slider: you're (correctly) always urging us to keep it real. To my eye, in most images, 100 makes it unreal as some convergence is part of our visual world. Please keep the videos coming.

Thanks for this great explanation. I am thinking of switching from LR to C1, and currently using the trial version. This video helps explain the Keystone tool very well. Great work.

Awesome breakdown of a much intimidating tool. Great job Paul.

Muchas gracias.

Thank you, Paul. I am fairly new to capture one but not making the headway I would like to make, your videos are clear and concise and your teaching is easily absorbed. I guess time and practice is the keystone (pun intended) to learning this photo editing software.

Brilliant explanation, very informative and easy to follow 👍. Thanks a lot

Makes it sound easy! Well. done!

Another great tutorial. Thx Paul!

Thanks for a very instructive, far-beyond-the-basics, well-prepared, calm and unhurried tutorial! (I could just do w/out the "smashy" intro/outro jingle, but understand it's done on YT.) When you finetuned the correction on the coastal church and in the Brisbane shot by minimally re-adjusting the keystone tool and guide-lines, i wondered if it wouldn't have been easier to play with the Vertical/Horizontal sliders in the Keystone panel? More generally, i wonder why KZfaqrs record their tutorial screen in super high resolution, maybe even in 4k. It leads to very tiny elements in the graphic user interface (like very tiny buttons, panels and overlays). Wouldn't it be nicer to record in HD oder maximally Full HD - to show a much bigger, less faded GUI that's also less destructible by KZfaq's compression? Anyway, a very instructive, pleasant video by content and way of presentation!

Great tutorial Paul!

Fantastic tutorial, learnt so much

the video is fire of keystone :D thanks so much for this! Just trying to edit pictures of very bulky furniture for music studios and found this video very helpful to sort out the issues that came with shooting in a small space. Zulfiya

Excellent tutorial. Thanks!

Another awesome one....

As far as I'm concerned the only thing C1 is missing now to be a true Lightroom replacement is the automatic keystone tool for all cameras.

Great video. Can’t believe the stupidity of C1 setting default amount to 80. So frustrated until I found that slider. As for “keeping it real” what’s real about 80. Why not 70 or 90. The default should be to fully do what the tool says it is supposed to do.

Really useful way to draw out those pesky splodges, especially for macro at small apertures. I guess tho the removal layer might be best using spot removal rather than heal points/strokes if you want to reuse (copy/apply) the dust removal layer to another image as the heal sample points might not be appropriate in the next image - unless you can get them to be resampled that is. Any thoughts?

I swear I cant see. they are all straight for me :D

Is there a way to change the lines from a thick white line, to what you have in the tutorial here (slimmer, dotted line)?

Thanks for your informative tutorial, Paul. Question; how did you get two vertical lines in the Guides tool? I only see one? (one vertical and one horizontal line). Searched how to adjust it but it is hard to find.

Has there always been a four-way keystone option? I know in the past I have tried to apply a vertical correction, and then a separate horizontal correction, but C1 wouldn't let me use both at the same time?

Thanks, is it possibly to change the fault to 100?

The feature request here is that Capture One show automatically a lupe/magnification when you move the circle/point of the keystone tool.
