From plastifying your pictures to changing them to enameled ceramics with more or less pronounced bump and more or less noise and many other settings, these svg filter effects will give them impressive and realistic bump. Modifiable and very versatile.
Tip : as you will see in the svg file they can be also applied to vectors. In this case, play with gradients and/or HSL and you will be very surprised.
DON'T BE WORRY if at the moment, the navigators are unable to display correctly most of my filters. Inkscape display them nicely and export them as you see here. My first wish while creating these filters is to improve Inkscape illustration capabilities.
