Which Software Works Best?
All three software has displayed a remarkable outcome in old photo restoration. Here is the evaluation:
Imagecolorizer:
The first is ImageColorizer which is very easy and fast to use. The quality is good, and it is free to use. It is perfect for the essential enhancement of colors. There are not many limitations for a free account and support the max image size.
Meanwhile, from the data, we can see that imagecolorizer is the only software that colorizes the black and white photo while compressing the output size. That means users can save and share the colorized photo fast and easily because the image size is small.
Hotpot AI:
Hotpot AI performs better than Vance AI as it supports users in choosing different colorization factors. Users can decide which degree of factor to apply to the old photos. The value bigger, the colorization level higher. If you apply the max colorization factor, the color and contrast of the photo will be more obvious.
Considering that this is a free tool, the results of the photos are promising. Perfect for a high-quality restoration.
Vance AI:
Vance AI works well with output image quality. And it adds to color fast and accurately. Better yet, it offers a real-time preview of before-and-after effects. You can know the colorization results.
However, Vance AI is an all-in-one photo editing toolkit. It may be a little bit hard to find the photo colorizing features instantly. Also, there is a limit to using it as it is not a free tool.
