Watermark

[nitr0uzv]

Wouldnt it be cool to have a camera with built in watermark feature?

are there cameras with built in watermark features?

I have Canon A510 and it has a date/time stamp feature but only at resolution 1600x1200. Other cameras probably offer the same feature if that's what you're looking for.
Other than that, you can batch process them to give all of them a watermark.
