How to Smudge a Photo in Photasium
A hard join, a thin scratch, or a line of type you would rather hide can be dragged with the colour beside it. In Photasium that happens in the tab: the file never goes to a server.
Colour along the stroke
Smudge paints on the active raster layer. The stroke picks up the colour under the brush and lays it down as you drag, then picks up again, so the colour travels with the pointer. Strength mixes that carried colour with the pixels that were already there. A press that stays in one place leaves the layer as it was.
Blur softens or sharpens the pixels under the brush and leaves them where they are. Clone stamp copies pixels from a source you Option-click. Brush paints the foreground colour. Smudge carries the colour already on the layer along the stroke.
A hard edge that should sit in the photo
A story often has a logo, a sticker, or a cutout whose edge looks stuck on. Drag along that join with a small size, a low hardness, and a modest strength, so a little of each side travels into the other. Leave the face or the product alone.
Duplicate the raster first if you want the original pixels still in the stack. Layers keeps that copy.
A listing shot can have a thin scratch or a dust line across the product. Drag from the colour beside it across the line, with the size close to the mark. Heal patches a spot with nearby texture when you let go. Smudge pulls a colour along a line.
A screenshot can include a name or a number you do not want to share. Drag across the letters so the colour beside them runs through the type, and the rest of the window stays sharp. A short stroke with a high strength moves more colour on the first pass.
A scan with a fold or a crease can take a stroke along that line, so the paper colour on either side fills it in. Keep the size close to the crease and the hardness low, so the edge of the stroke blends into the page.
Smudging in Photasium
Open a photo
Open the editor, then File → Open, or drop an image on the canvas. Select a raster layer.
Choose Smudge
Click Smudge in the toolbar, or press S. The options bar says to drag to smear pixels along the stroke.
Set the stroke
Size runs from 1 to 500 and starts at 48. Hardness runs from 0 to 100 and starts at 60. Strength runs from 1 to 100 and starts at 50. Press [ or ] to change size while you work. A lower strength mixes in less of the colour you are dragging, and a second stroke goes further. A lower hardness feathers the edge of the smear.
Drag
Drag on the canvas. Colour under the brush at the start of the stroke travels with the pointer, and the stroke keeps picking up what it crosses. A press that stays in one place leaves the pixels as they were. The foreground colour stays in the foreground well.
If a selection is active, the stroke stays inside it. Smudge needs a raster layer. It paints that layer’s pixels. If the layer mask is what you are editing, the stroke lands on the mask and drags the mask along the stroke. A text layer asks you to rasterize first. A locked layer will not accept the stroke. A group does not take the stroke, so select a raster inside it. Undo restores the layer to how it looked before the stroke.
The colour on the pixels
The stroke sits on the raster you dragged, nothing was uploaded, and undo brings the previous pixels back. If the pass is too strong, undo and lower Strength before you drag again.
Download PNG, JPEG, or WebP if you need a file to send. Come back later and the document is still listed under the editor, until this browser’s storage is cleared. Smudge sits with the other photo editing tools: blur a patch, heal a spot, and export a listing.
