What format should my logo watermark be?
Use a PNG file with a transparent background. This ensures only your logo appears on the photo without a rectangular background. White or light-colored logos work best on most photos.
What opacity should I use for a watermark?
30-50% opacity is the sweet spot. It's visible enough to deter theft but subtle enough not to ruin the image. For portfolios, 20-30% is common. For proof images, use 50-70%.
Where should I place a watermark?
Bottom-right corner is the most common position. For stronger protection, use a diagonal repeating pattern across the entire image. Center placement is harder to crop out.
