Bump Distortion for Mac

What Bump Distortion does

Warp an area with five styles
Twist, pinch or bend a selected part of the photo with Bump, Linear Bump, Pinch, Twirl or Vortex.
Keep named variations
Save alternatives under their own names and keep each one editable. The version chosen for delivery stays as it is.
Compare at source size
View two versions or the original side by side or in a split view, and check the photo at its source detail.
Adjust warps on the photo
Move the on-photo controls, combine warps in order, and undo or redo each adjustment.
Reopen a study file later
Save a .warpstudy file with the photo and its variations, and reopen it even if the original image has moved.

Step 1 of 4
Open your photo
Start a study from one source photo.
Step 2 of 4
Warp the area
Choose a warp style and move its on-photo controls until the look is right.
Step 3 of 4
Keep and compare variations
Name each variation, then compare it with another edit or the original.
Step 4 of 4
Export the chosen image
Preview the chosen result, then save it as PNG, JPEG or TIFF, or as a labelled sheet of 2–6 options.

Does it change my original photo?

No. The study keeps the photo and its variations separately, and each edit is saved as its own version.

Which formats can I export?

PNG, JPEG and TIFF. You can also create a labelled photo sheet with two to six alternatives.

Can it handle several photos at once?

No. One source photo per study. The app is not a batch processor.

Opens one photo per study. Saves PNG, JPEG or TIFF, or a labelled sheet of 2–6 options.
