I'd think this would be possible - I have a photo of trees, with an isolated tree in the foreground that is leaning a little bit, it makes it appear I held the camera at a slight angle, so I'd like to select that single tree and straighten it without changing anything else. Is it possible? Any suggestions? I tried to attach the photo with the imgbb button thing but it didn't seem to want to work. ![]() |

Thanks! That helps!
I believe the Camera Distortion filter will do the job. Just correct the Vertical Perspective. You may also have to do some adjustment to the Scale (Edge Extension).
helpx.adobe.com/photoshop-elements/using/retouching-correcting.html#correct_camera_distortion
You could also try this technique.
1. Turn on the Grid (View>Grid). 2. Do Free Transform (Ctrl-T, Cmmd-T on a Mac). 3. Hold the Ctrl key down (Cmmd key on a Mac), place the cursor on the left bottom corner handle and drag it to the right until the tree is straight. Use the Grid lines for guidance. 4. You will notice the other trees in the background will begin to lean a bit. To fix this, repeat Step 3 but this time place your cursor on the right bottom corner handle and drag it to the left.
NOTE: You may have to do some cropping in the end to get rid of the transparent areas. Or you can use the Spot Healing Brush to "fill" those transparent areas. |

Filter>Correct Camera Distortion Vertical perspective set to -40 produces this result.   |

If you crank up the vertical perspective correction to around 64 and then pull out the bottom left and right corners slightly (Image->Transform->Distort and set the anchor point to the bottom middle as in screenshot) to fine tune the background trees you will get something like this.  imgbb |

Another option is using Elements 15's new Perspective Crop Tool. It's found in the tool bar with the crop tool. The top of the tree is preserved. The ends are shortened when you crop the image after using the perspective crop tool. For this image just pull out the lower corners out and align with the grid. Then crop. Note: I didn't get the tree totally straight. To correct it repeat the process until it's as straight as you want it.  |

Thanks Moto - I hadn't noticed the Perspective crop - I was going to suggest adding height to the picture so that the top of the tree stays visible then clone the sky to fill in the blanks. But your way is much better.

I'm at Elements 10, so that perspective crop tool is not available to me. I did use the distortion thing, but found I was cutting off the top of the tree like Deprosq did. I suppose I'll just leave it as is, not so bad, just makes it look like the photographer (me), didn't hold the camera straight, although in the background you can see that the rest of the trees are straight. I had the idea it might be possible to select the tree and tilt it slightly, but that doesn't seem possible, and even if it was, would cause new problems. Thanks for the suggestions.

You can use the Camera Distortion filter and still preserve the top of the tree. As I mentioned earlier, you may also need to adjust the Extension Edge (Scale).
Another possibility is to use the Free Transform command as I suggested earlier. You will end up with only a narrow strip of transparent areas on the side edges of the photo. Just use the Spot Healing brush (J) to "fill" those areas. Or you can do a little cropping to get rid of the transparent areas.
1. Turn on the Grid (View>Grid). 2. Do Free Transform (Ctrl-T, Cmmd-T on a Mac). 3. Hold the Ctrl key down (Cmmd key on a Mac), place the cursor on the left bottom corner handle and drag it to the right until the tree is straight. Use the Grid lines for guidance. 4. You will notice the other trees in the background will begin to lean a bit. To fix this, repeat Step 3 but this time place your cursor on the right bottom corner handle and drag it to the left. |

pwahl, I just tried Sepiana's suggestion of using the Correct Camera Distortion filter - Vertical Perspective -51 and Edge Extension 70% and it came out perfect the first time, and it was also easier to achieve. Crop image after using Correct Camera Distortion. Note: In fotofrank's and deprosq's images they used Veritcal Perspective, but not Edge Extension. That's why the top of the tree was cut off. After adjusting Edge Extension - which reveals the top of the tree.

For users of Elements 15 only.Another option to straighten the tree is to use the new Elements 15 improved Content Aware Move tool.It adds rotation and resizing options after moving/coping. Note: For this image using the Correct Camera Distortion filter is quicker and easier to use. Additional Note: The Content-Aware Move tool was almost as easy as the Correct Camera Distortion filter. For this image see more details here. photoshopelementsandmore.com/post/29009This example shows rotation only using a before and after animated gif. Two Steps: Straightened the tree trunk and then the treetop.

For users not using PSE 15 another option is to select the tree and cut it onto a new layer: Layer->New->Layer Via Cut. Hide the new layer in the layers palette. Then on the original layer fill the transparent portion where the tree used to be with the sky and background trees. Very simple and quick. Make the new tree layer visible again and rotate just this layer until the tree is straight. Image->Rotate->Free Rotate layer. I have made just a rough selection of the tree for this demo.  |

Moto, thanks for trying my suggestion! Yes, indeed, adjusting Edge Extension (Scale) is a key ingredient to a successful use of this filter.
