NostalgiaPhotoRestoreVideo did a mediocre job of coloring my black and white photos. Many it would leave large areas if the photo UN colored, leaving one of my dads arms grey but the other colored, my grandpas face was turned to green but his hands looked normal. Other details were hit and Miss.
On colored photos that had yellowed from age it actually seemed to make them worse vs better.
I wish there was a way to tell it what the color of something should be line outline an area and tell it this is blue (maybe outline and select from a drop-down menu).
I had a bit better luck removing all color from the photo with my iPhone and then trying to colorize, but it wasn’t enough of an improvement to keep NostalgiaPhotoRestoreVideo.
I wish there had been a trial of NostalgiaPhotoRestoreVideo prior to purchasing. Even if it was watermarked first, because this was disappointing.
