I found an old 2" x 2.5" photo of my Mama and Tita so I scanned it. This is my first attempt in restoring an old photo and adding color to it.
I first converted the image to black & white then I used Hue/Saturation with Overlay/Soft Light/Linear Light Blend Mode and Mask to color the picture.
I don't know if it is the right way to color it but I'm happy with it for now. I will update it again once I got some new techniques.
