There are several options for colorizing a black and white photo without using Photoshop. One option is to use SoftOrbits, which is downloadable software for Windows that can be used to colorize and enhance old photographs. The photo editor will help you remove scratches, noise, or other imperfections in the image. Once you're ready to colorize, you can click a button and let the app do the rest. Another option is to use Image Colorizer, which is a hassle-free tool to colorize black and white photos. You can ignore the pricing information as you don't need to create an account or pay to use the colorizer tool. Simply upload your black and white photo and the app will add color to it automatically. Other options include PhotoGlory, Fotor, and Img2Go, which are all online tools that can be used to colorize black and white photos. These tools typically use AI-based image colorization algorithms and deep learning to add natural, realistic colors to your old black and white photographs.
