PhotoPatch Pro 4+‎

Edit and overlap two images in a professional and easy way just using your fingers!
Overlay them in creative ways with transparency and blending effects. Select which parts of the images to keep or to erase, add effects to the images. Enjoy a realistic preview of the final result during the entire workflow.
Being made by a photographer, this app is conceived with ease of use in mind.

Features:

- Load background and foreground images from the photo library.
- Swap the foreground and the background images and choose the best overlay combination.
- Move, scale and rotate the foreground image with your fingers and align it to your liking.
- Flip the foreground and background images horizontally or vertically.
- Select/unselect areas of the foreground or background images through selection tools and options.
- Selection tools: brush, eraser, magic wand, linear and circular gradients with creative user selectable parameters (edge hardness, tolerance, opacity points, ...).
- Enable the magnifier on brush and eraser tools for fine-tune masking.
- Apply filter effects to the foreground and background images (17 presets available).
- Tune the foreground and background images (exposure, brightness, contrast, saturation, vibrance, hue and sharpness).
- Overlap the foreground and background images with 19 different blending effects.
- Vary the transparency of the foreground and the background images.
- Undo/Redo your latest action.
- Export/Import foreground and background selection masks.
- You can even use any other image as a selection mask for the background or foreground image for outstanding creative results. It will be automatically stretched to fit the image it masks.
- Enjoy a realtime realistic preview for the entire workflow.
- When you're happy with the preview, just press the patch button and the foreground image will be merged to the background one.
- Export the resulting image with full original metadata to the Library, Facebook, Twitter, by E-Mail, etc.
- Two export formats supported: JPEG (with user selectable quality) and PNG.
- Three export sizes offered: Web (max 640 pixels), Medium (max 1024 pixels), Full (original size).
- A help page is always available inside the app.

The ease of use of this app really opens your mind in a creative way. You can use it to apply textures, watermarks, frames, making double exposures. Just repeat the patching process with different foreground images to make multiple exposures.
I'm also an art photographer, look at my portfolio for some samples what you can do with multiple exposures (www.marcoristuccia.com).
