If you're familiar with Photoshop (or Photoshop Elements) for the desktop, you already know that that application's power lies in its use of layers. PS Touch is no different in this regard.
Because of the innumerable uses of layers, I can't begin to tell you what you need to do. I know that you have two layers but I don't know how you want to blend them together. Do you want to do this artistically? Do you want to take one part of one image and add it into the other?
ON EDIT: Oh, and there's no manual for PS Touch that I know of.
Thanks for your reply. I am a nail tech and want to combine an image of a hand before a treatment with an image of the opposite hand after a treatment but as I am not used to using Photoshop I'm afraid I don't know how to do this. The tutorials aren't that helpful if you don't know what any of the symbols mean!
This assumes that you have your two images residing in your device already. Note also my screenshots may differ from yours depending on mobile OS being used (Android 4.1.2 in my case). The manner should be the same, however.
Note this technique works best for images that have a similar or the same background. It's also the fastest.
Tap each image to enlarge if you can't see any details.
I browse to the first photo for the project
I browse to where the images reside.
The first image inserted. I tap the "add image" icon in the upper left, second icon from right.
I browse as I did before for the first image. The second image, inserted, waiting for me to confirm by tapping the checkmark.
Both images now in the project. Now the magic begins.
Next, I tap the ampersand icon in the upper right, second icon from the right, then tap, "Fade," in the pop-up menu that appears.
I'll want to choose a fade depending on the location of the objects in each layer. In this case, I chose a fade that has 100% opacity on the left (indicated by total red) and gradually fades into 100% transparency on the right (indicated by a greyscale checkerboard). Arrow 1 points to the fade chosen. Arrow 2 points to the handle I will tap and drag to the right to adjust the amount of fade between the two layers.
The result. I then tap the checkmark in the lower central right.
The final image. Note how the topmost layer fades into the bottom layer in the layer panel in the lower right.
I can then save this project and export as usual. And that's it. If you have any questions, just ask.
Hi again. I managed to merge the two pics so many thanks for the detailed instructions!
