Nice basic introduction. Three things that you might want to consider adding are the importance of using a tripod; the value of using a remote and that a long exposure calculator can be downloaded to your phone for determining exposures longer than 30 seconds.
Thanks for sharing. I have already learned a few things from it and it sparked my interest.
- As an indication, add a table of equivalence of stops for a few densities (nd 0.3 = 1 stop; nd 0.6 = 2 stops; nd 0.9 = 3 stops […]. - Slide 12 : small font difficult to read. - Slide 12 : “circular or screw on”. It can be seen as two different things (Would circular without screw on exist?) If it is not the intention, maybe eliminate the synonym. - Add a few links on the Web as references on the subject.

Good presentation but I did wonder about your brief comment about variable density filters. That’s all I use and I didn’t really consider it expensive (mine’ a Cameron and was around $70 when I got it). More expensive are around but I’ve not had any issues with mine. I can see why it could be useful for video but it’s also good for still as it saves carrying around a selection of fixed ND filters. My main use is for waterfalls and they vary greatly in the ND required so the variable is very handy. I’ve also used for sunsets at the lake to smooth the water and tone down the sun. Again being variable makes it easy to adjust as the sun goes down and loses brightness.
Just some thoughts on my experience

Maybe it's just me, but all I get on that link is a many-paged PDF of blank white pages.
As for the variable ND, I had a really nice one that went from almost nothing to completely black/dark, until the hanging loop on the wife's filter wallet gave way and it landed on the blacktop.
I keep a gradient ND on my camera almost 99% of the time --- even indoors; I don't have nearly so much indoor lighting problems when the gradient ND is on.
On a similar note, the wife forgot and left her CPL on the camera when she took a few hundred indoor shots in weird lighting and they turned out so good that she decided to be certain it is on there the next time she has an indoor project; maybe that is not the accepted way of doing things, but we go with what works for us.

On a poverty-level Kentucky budget, a 24-exposure roll of film would have two Christmases and a summer vacation on it and we might have to wait another six months before being able to afford developing the film.
I still have trouble remembering that it doesn't cost anything to take thousands of pictures; it just almost seems impossible to be true.
