Well, as a keen photographer myself, when I look at images on the internet, especially on some of the photography forums that I use, I sometimes like to look at the settings a photographer has used, and also the equipment.
For example I could tell you the serial number of your 600D and also that of the 18 - 55 EF-S II lens that you used for these images and, for the last image your settings were 1/160th, f7.1, 100 ISO
It's all about the EXIF info embedded in the image file, I use an EXIF viewer.
I looked at yours because I was impressed by the quality of the images, hope you don't mind.
ps. if you don't want people looking at the EXIF, there are programs that will strip it all out from an image file.
