![]() Then switch to "warp" mode in the toolbar and shift-click all the lines that need to be made vertical/horizontal. There are two techniques with this tool, use either, both or mix them as needed.įirst, if you have specific areas where you want lines to end up straight (either horizontal or vertical), use this tool to define quadrilaterals ("quads") which line up with those lines. The first two tools can be used in a few ways: Using "Perspective Warp" "Puppet warp" also has uses but it's also very much harder to keep smooth. There are several ways to fix this, but the big ones are "warp" and "perspective warp". But in the end I found a way to do it in Photoshop. Googling other tools or the general phrase "bend along a line" may help find other programs. I found some tools seem to have such a tool (see list below), but Photoshop doesn't. The tool needed is to distort (or undistort) a path, so that the path becomes straight. I finally found a good answer, which I'm posting here because I couldn't find the answer anywhere else, either here or online. I'm not saying it has to be this kind of effect - the photos above show what's actually needed - but this might give an idea how I think it could be done: (There is no need to fill in the space created between the original edge and new curve, it can be ignored). It lets me specify an area to be distorted, and I drag some points on the edge to where they should be mapped to, and the area is smoothly distorted as I've tried to show. ![]() The diagram below tries to show the transform or filter in abstract terms. This is the kind of effect I need (the line in the middle is roughly correct): This is a thumbnail of a typical image I'm trying to fix. It also insists on distorting all 4 sides equally which isn't helpful either (as you can see in the sample image below). The " Correct Camera Distortion" tool is closer to what I need, but I can't find a way (if one exists) to define a line I consider "straight". ![]() The Warp tool doesn't seem to allow the edges to be distorted to match the curves created by panorama imaging it warps the interior near a given point only. The Pinch tool seems to have a maximum effect of only 600px and doesn't let me control the effect appropriately for the problem (it calculates the effect across the diameter of tool, instead of letting me specify a curve which indicates how much the effect is and smooth it into the image as I would like). The " Free Transform" tools don't seem to let me select midpoints of the edge of an image and move them in or out.Īdobe Help says to use pinch or warp, using filters rather than transformations. ![]() Tools tried (I'm not very experienced so maybe they work and I just don't know it): I don't need to fix these photos to professional standards, just enough that they look casually okay, so the person I send them to can get a better sense of the actual layout without having to work out what's straight and what isn't - basically reduce the gross distortion to a minor distortion. (If Elements 10 takes plugins and there is a good plugin for this, better than built-in tools, that would be fine) I suppose I could download a different program if I needed to, but would prefer not as I'm under a lot of time pressure. I'm using Adobe Photoshop Elements 10, which has a nice range of tools. The phone and its camera are good quality, so the panoramas are stitched nicely for what I need the fix required is basically pinching, warping, or distorting using a curved effect, because the resulting image often has straight lines shown as curves. ![]()
