PTMD is an application that allows you to add blur background on photo, similar to phones with two cameras. The app is based on machine learning.
• Add blur background on old photo or photos taken with one camera in one moment.
• The application provides several blur styles (Bokeh, Box, Motion, Crystallize, Pixelate).
• Choose the intensity of blur using the slider.
◉ Improve model AI
◉ New UI/UX
○ Adapted for iOS 14
○ Bugs fixed
Ratings and Reviews
Does what it says… Hear that.
I just tried it out and I’m impressed. I don’t know of another app that does what this one does. ‘Specially not a free app. All I can say is try it on one of your photos, and see if you’re not impressed. And get it while it’s free! Thank you to the developer, I know I’m going to use this a lot.
So might feel that the interface is not very intuitive, but since there was no button to push to go to photo albums, I had to experiment. I opened my photos selected a photo then went back to this app and the selected photo showed up in the little window and I was able to use it. Good luck and have fun with it.
OK, but could be improved
The app does a pretty good job of isolating the subject before applying the blur, and the two edit tools are useful to tweak the “coverage” of the to-be-blurred area. The problem is the sharpness “fall-off” from the subject’s sharp edge to blur should be more gradual, not so abrupt from sharp to blur, regardless of the amount of blur setting.
The effect looks its best if the amount slider is used minimally, and avoiding a heavy-handed max blur approach. In my particular image test, I needed an “appropriate amount” of maximum blur applied to background objects of varying degrees of distance from the subject, but the end result looked exaggerated and “obvious” as the fall-off went abruptly from sharp to max blur over the entire image. Everything was the same level of blur.
To real life the “depth of field” of wide aperture lenses, the transition is very subtle/gradual, going from sharpness to blur in front and in back of the subject, a very difficult effect to mimic in post processing.
Another suggestion, making the app Universal to facilitate better edits using an iPad would be an improvement. The app works OK on the iPad, but there is a lot of wasted screen real estate.
A very good effort that will work pretty well for some images if used sparingly, but could use additional improvements.
Works well; mostly
Good app and effects. Only big problem is it sometimes fails to identify an object, which is required to blur the background.
Also has trouble with multiple depth pics, such as when shooting a person with her hands forward, holding an object: the object isn’t recognized and the effect fails.
If it updates to AI improve and adapt to better iPhone cameras and iOS 15 then this could be a great app.
Until then it’s 3.5-to-4 stars.
