There's a Healing Brush tool and a Clone Stamp tool in addition to a general "soft skin" effect (which can, of course, be applied selectively via selections).
Please describe step by step method to soft skin with Photoshop touch or paste some link.Thanks in anticipation
Healing/cloning in PS Touch works very much like it does in Photoshop. You select a source for cloning or healing and then brush over what you want to replace or fix. Experimentation is key.
A few tips:
Start with a duplicated layer of the original image. (Tap the "+" icon in the lower right of the PS Touch workspace > Duplicate Layer.)
To isolate the area so you don't accidentally spill over into undesired areas, make a selection using the Brush Selection Tool, then, if desired, refine that selection using the selection options command. (4th icon from the upper left > Refine Edge.)
I wouldn't use a brush at 100% opacity; maybe around 80% or so. Depending on the resolution of the image, you probably won't need a big brush size either.
Think about other effects too, like Gaussian Blur as well as Soft Skin and the opacity of layers. (Adjust opacity by tapping the icon in the lower right that looks like two stacked diamonds.)
Three-finger tap the project to toggle between fit to screen and 100%. (Of course, you can use two fingers to pinch zoom in and out.)
