Photo distortion

[jackamus]

I don't use AP very much so I'm not too clued-up on editing a photo.

I have a photo where I want to drag the bottom right corner down so that the image is parallel.

I have tried Filters>Distortion but none of the options seem to apply.

I would play with the Perspective Filter, available as a Live Filter via the Layers menu or the Live Filters icon at the bottom of the Layers panel.

Hi Walt, Would I be correct in assuming that the previous version of AD, under Filters>Distortion, it was possible to drag the image handles?

Designer (AD) has never had a Filters menu, but Photo (AP, or APh) has.

In your example document you have (or something has) cropped the image.

This is causing the filter to be unusable.
In Photo, try menu “Document → Unclip Canvas” before using the filter.

Because of this, the filter boundary and handles may not be visible.

Try zooming out to see them.

Clarification.

Sorry my mistake! It was AP. I did crop the image first and then wanted to 'Distort' the image. I will try again before cropping the image.

I was able to use the Filter on the image @jackamus provided.

I'm working in AP 1.10 and the perspective filter works fine. it's a good idea to have the Grid displayed as this will help with alignment. I also used a few guides to try and put the pole ends back to where they were (Blue lines)

1. Unlock the image layer.
2. In the workspace zoom out to approx 50% so you can see the bounding box of the image (To crop the image to the document edges you will need to rasterise the image by right clicking on the layer and choosing Rasterise and Trim) but I would recommend leaving it as is and it can be rasterised once you have the image parallel and you can adjust the image better in the canvas prior to rasterising it.
3. With the image layer selected, choose the perspective tool on the left side toolbar, you now get a a bounding box with a white edge and white nodes at each corner.
4. The trick here is to try and maintain the length of the poles but distort the image such that the poles will be parallel to the edges of the top and bottom, so, click on the bottom right node and drag it until the bottom pole is close to the edge of the canvas (see fig 2), this is required because in the next step you are going to bring the top pole back parallel with the top and you needed to exaggerate the distortion to compensate for the next step. 
5. So, now you have distorted the bottom using the bottom right node, you need to bring the top pole back using the top right node, this will also adjust the bottom pole, lifting it back straight with the bottom of the canvas edge.

With a bit of careful movement you should end you with something like this...

fig 1 unadjusted

fig 2 Adjust the bottom node

fig 3. Adjust the top node

Oops, my mistake.

The Perspective Filter boundary and handles were actually outside of the visible part of the document because of the cropping.

Zooming out allows them to be seen.

I’ve edited my earlier response as appropriate.

Thank you for the explanation which worked for me.

As far as I can remember I never had to select 'Perspective' from the 'Distort' filter in the past that is why I asked if this was in the previous version of AP?

The menu item “Filters -> Distort” has no function by itself, it’s just there to take you to the actual filters, Perspective, etc.

In other words, there’s no such thing as a “Distort” filter, but there are lots of distortion filters.

It’s always been like that as far as I know.
