Is there present in Photo2 a tool to correct perspective distorion by the camera not being dead-on ?


Recommended Posts

To implement a fix, for instance for the camera looking up and rendering parallel lines as  / \ the desired rendering would be for the same lines to appear as | | in the image.

In PaintShop, I'm used to working with a rectangle with a handle on each corner that can be positioned independently.  For example to the top and bottom of the four points / \ in this example.  Thus the result can compensate for the camera being above-left, above-right, below-left, or below-right of the target.  I've even been able to use this on a sign that was facing away at a 45degree angle from the camera (after putting the sign on its own layer), to make it readable full on.  

I've tried Photo's Perspective tool using the "unconstrained" mode, but for instance if I move the top-right corner down, the top-left moves in lock-step. Although "unconstrained" gives me freedom to customize my own image ratio by eye, that's not the same as allowing all 4 corners to be managed independently.  Maybe the tool exists elsehere in Photo, but I just haven't found it?  In the meantime, I could work with PaintShop, but just as soon stay in the same editing environment.

Thanks.

 

Simple Example attatched: trying to match the 4 corners of a TV screen. (The TV screen is gently curved, but I wasn't trying to correct for that. Correcting for everything would be even better :), but what can be done? Thanks.IMG_20221229_1146B pano.afphoto

Welcome to the forum @TacoMonster

The simple trick is to switch to source mode.

  1. add a rectangular shape (no fill, only stroke) showing the "to be" situation
  2. add perspective adjustment. The 4 nodes should match the rectangle.
  3. switch to source mode. move the nodes to match the distorted source image

Perhaps this InAffinity tutorial will help? It adjusts four corners of a rectangle independently.

Success! Thanks all for your input. All is well.  

Getting used to Photo2 is well worth the investment.

The video was very helpful, in letting see step-by-step what the directions meant to show.  Also, I can see the value of not-my-fault's creating a rectangle independently. 

You are all appreciated. 

Kind regards
