How do I make a transparent watermark?

Use an rgba color value like rgba(255,255,255,0.5) for a semi-transparent white watermark, or rgba(0,0,0,0.3) for a subtle dark watermark.
The last value (0.0 to 1.0) controls transparency — lower values make the watermark more transparent.

What position should I choose?

Center is the most common position for watermarks as it's hardest to crop out. Bottom Right is commonly used for subtle branding.
For diagonal watermarks across the entire image, use Center position with an angle of -45 degrees.
