When it comes time to watermark your photos it’s rarely a one-time, single-graphic process. Chances are you have a ton of photos, and need to watermark each one without spending hours on end manually watermarking each photograph – one at a time.
GFXMark Free steps in here and offers a free Windows application which will let you watermark your photos with a range of different options. For starters GFXMark comes with built-in brightness awareness – which will automatically analyze each image and choose a dark or light watermark to showcase over it. The same concept applies to the watermark opacity which is constantly edited to produce the best looking watermark across many different types of images.
Now I must mention that this free version of GFXMark does have some limitations. For starters it only accepts 10 images per operation; and there’s a maximum export resolution of 1200 x 800. However the brightness-awareness makes it worthwhile anyway.
