Forgive me for writing this but after weeks of searching and playing with the application I have been unable to find a way to do it. Granted I am very new to Photoshop. I would humbly appreciate an answer from anyone on the matter. I am trying to see if I can mirror photos on Photoshop for IPAD like so.
Moved to Photoshop Mobile forum from the Photoshop forum.
First versions of Photosho on the iPad focused on basic compositing, retouching, masking, and other common tasks. We will add many more features moving forward and we appreciate your feedback regarding those that you believe are the highest priority for your workflow. The mirror feature is not currently available on the iPad. For an idea of what is coming soon, see this link: https://theblog.adobe.com/photoshop-reimagined-for-ipad-the-journey/
Feel free to make feature requests so our team knows which features are most important to you. If someone has already logged the feature you are hoping for, then you can add your vote to their post.
If you open/import the file on the iPad you will not need to promote the background layer. It is already done for you.
Instead of using Image size you could use the crop tool and expand the canvas that way,
Guides are not currently available so you will have to eyeball it
To load the selection from the layer, choose Load as Selection from the (...) menu on the side with the layer active
With an active selection Transform Selection is available from the (...) on the Selection ask bar at the bottom
Copy and Paste of Selection contents is available on the right side task bar (...)
Select the Transform tool then flip using the flip buttons at the top right to flip horizontal
You can either move the image over wile in transform or use the move tool after transforming. You can constrain the move in transform or with the move tool using the touch shortcut to prevent up or down shift
Trimming would need to be done with the crop tool
Hope this helps...
TS Darbari - The quickest way to flip an image on your iPhone or iPad is to use the Photos app.
With the Photos app open, tap the image you want to flip.
In the upper-right corner of the screen, tap Edit.
Tap the crop icon. It looks like a box with overlapping lines and has two arced arrows pointing in different directions.
