Watermarking a Myriad of Colors
Category: Digital Room

I'd been adviced to watermark the pictures I post in public domain for a while now. Hence, I was trying to atleast find out how to do it, using my favourite image editing tool: GIMP. The procedure turned out to be fairly simple:

  1. Open the picture in GIMP and Cut paste ur watermark logo into the image or bring up the text tool to add the text u want
  2. Bring up the Layers dialog (Ctrl-L) and select the background image layer
  3. Right click on the image and do Filter => Map => Bump Map with the default settings (experiment with the parameters to obtain different settings but default should work just fine)
  4. Go back to Layers dialog and delete the text (or the pasted logo) layer

The watermark effect is not very conspicuous here and hardly spoils the image, but is barely there to convey the source of the picture. Isnt this what the watermark is supposed to do? :) I used the "Script MT Bold, Bold" font, with size 144 and placed the watermark at the top left corner in the picture.

I still havent made up my mind whether to put the watermarks in to the pictures I post here. It hardly makes any sense, especially since I am posting only small sized (max 500 x 750 pixels) pictures here. But I may end up doing it for wallpaper sized pictures at other places in the site.

Yeah .... the picture is taken @ RT Nagar house (indoor, night, artificial lights) using the EF f/3.5L 180mm lens, mounted on a tripod. I used Av mode with a -1Ev exposure compensation @ f/13 and ISO-100 for a timer triggered 30s exposure.

I think it's a good decision to watermark the images because they're all original is it not? Let them not hinder the images but.

 Good one Sandeep.

Thanks for sharing this process, Sandeep. You have really simplified it (for me!).

Great photo of the peacock's feather!

Liked the shot.

I have started messing around with GIMP.  Isn'tPhotoshop more user friendly?

Feathers so immaculate……even the god loves it to give it a place on his hair. 

Light or night could not alter its magnificence. Dark background gives it a mysterious look. Did you try it on a paler background?
