Website offers free, reasonable AI colorizing for old photos

     Colorizing black-and-white photos is almost as old as photography itself, with people striving to make pictures look more lifelike.

    In the past, it usually involved meticulous hand painting of photos, a task that got relatively easier with digital photo editing software.

    Now, one of the new features in Photoshop is colorizing photos using artificial intelligence algorithms to do the heavy lifting. The results are fairly impressive, although there are naturally a few goofs that are relatively easier to fix compared to trying to colorize an entire picture.

    But suppose you don't have Photoshop, or the "Jack Sparrow" version you're using disables Adobe's Neural Filters?

    Vertexshare's Picture Colorizer offers a free AI-based colorization service that produces acceptable results. I played around with it for an evening and got some decent results.

    Here is a photo of Gen. Ulysses S. Grant taken from the Civil War. First, the original:

 

   And here's the colorized version (the only thing I did with the photo was just colorize it):

     It wasn't perfect, but things such as Grant's hand, his left boot and that yellow spot on the tent can be easily fixed in editing software.

    The main caveat with the service is that it only works with jpgs and pngs, and they can't be larger than 5 mb and 3,000 x 3,000 pixels. You might have to resize the image you want to colorize, as well as finish off any other edits you want to do, before uploading it.
