True – but only a very small percentage of the projects presented here (@ the gallery) are dealing with real life, compared to those being about making good renderings.

Yes! And you should try it!
Using steady landmarks to navigate, we can dash happily into the swampland and look for cloudberries, without fearing that a sudden overcast( or the equation of time) will lead us astray on our way back home. [:)]
