A recent offer from BundleHunt included PhotosRevive, it can colorise (colorize) B&W photos, I’d used a similar software program some years ago but it was more of a manual approach and a little hit or miss with results.
PhotosRevive is a drag and drop solution, just drag a B&W photo onto it’s interface, click colorize and in around 30 seconds you have a coloured photo. The program uses AI and in my opinion is actually very accurate. The first example here is a family photo from 1941, while not 100% correct, it’s close enough to give a pleasing result. There is an option within the program to make some further tweaks if you’re not happy with the result or it could be further tweaked in Photoshop or any other photo editing progam. The second example is a random photo I got from StockUnlimited, a subscription photo library I use, again PhotoRevive gives a very pleasing coloured result.
Overall, for a program that cost me $2.00 (normal price is $17.99) it’s a great little app to have on hand for those odd occasions when a tweak to an old photo could make all the difference.
