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
