A caption like your name plus the copyright symbol tells viewers and buyers who owns the image. Place the text in a corner at medium opacity so the credit stays readable without dominating the picture. Watermarked preview images are also much harder for others to pass off as their own work.
Type your brand name or handle as the watermark text and place it consistently, for example always at the bottom right. Pick a contrasting color, white on dark photos and black on light ones, and keep the opacity moderate. Consistent placement across product shots and social posts makes your gallery look professional and recognizable.
Light photos swallow white text almost completely. Switch the watermark color to black, raise the opacity towards 100 percent, and enlarge the text slightly if needed. Test against your brightest typical background, because visibility changes with every image and a watermark that shows on one photo may vanish on another.
Text size is set as a percentage of the image width, so the same watermark can look tiny on a small thumbnail and huge on a large photo. Always check the preview at full size, and stay within the 2 to 20 percent range. For a series of similar images, one fixed value keeps results consistent.
A corner such as bottom right gives a subtle credit that barely distracts buyers. The center protects more strongly because it cannot be cropped away, but it competes with the subject. Many photographers use a visible corner mark for public previews and keep stronger placement for images most likely to be reused.
