The Subtle Effects of Different Lighting on a Subject’s Face.

As most readers are aware I’m an incredibly amateur photographer having dabble in it on and off again for the past 5 years but only really started taking it seriously towards the end of last year. I’m still very much in the early stages of my understanding as whilst I can produce some pictures that I (and others) like my hit rate still feels incredibly low, especially when I set out to create a very specific image. A lot of that is comes from my still nascent understanding of how to light subjects properly and how the direction/intensity changes the resulting image.

Now whilst the following video isn’t exactly the greatest introduction on how you should go about lighting your subject (in this a model’s face) it does showcase just how dramatically you can change the resulting image simply by moving the light source:

Showing this to my wife she was adamant that they were splicing video together with different models as the changes are quite dramatic. It is the same person however as if you look at the eyes you can see the light source rotating at a rather impressive clip which is what gives rise to the dramatic changes in shadows. Pausing at different sections also makes it quite clear what the impacts of the direction of light are and how they are reflected in the final image.

I wonder what the effect would be if instead of moving the light they used multiple sources then just cycled through them. Hmmmmm…….

From Our Ancestors To Today: The Changing Human Face, Visualized.

Ever wondered how we evolved to look the way we did today from our ancestors that lived millions of years ago? Wonder no longer:

I often find myself digging through our evolutionary history in order to find out why we have certain features or why we seem to lack certain adaptations that other species have. Whilst I don’t have a good explanation for everything that’s shown in the video above (had I more time I’d get my wife, a fledgling biologist, to comment on it) it is curious to see things like the progress of the nose and the reduction of the large forehead. It also struck me as to just how subtle some of the changes are from generation to generation and yet that gradual accumulation ends up with the face we all recognize.

The best thing about this video is how clear it makes the transition from our common ape ancestor to our current form as┬áhomo-sapiens. Whilst I know that simply showing someone a video like this won’t be enough to convince them that evolution is real (indeed if you don’t want to understand it there’s little I can do for you) it does illustrate the point quite aptly. It also demonstrates the idea that whilst we shared a common ancestor we evolved along a different path alongside them, addressing the “well if we evolved from apes why are there still apes” question quite nicely.
