What I got from this blog:

and this blog:

Are that if you come from the world of photos going to video:
- When it comes to exposure you're boxed in by FPS. Think about it, if you are shooting 24 fps, the most amount of time any frame of video could get would be 1/24th of second.
- So when it comes to shutter speed, it can't be longer than your fps. It can only be smaller than your fps.
- We're all used to seeing shutter speeds that are at least 1/2 of the fps (as explained nicely in the blog). Going to smaller than 1/2 of the fps make the picture look stuttery (think Gladiator). You never want to go longer than 1/2 fps (too smeary).
- See this Lynda.com blog entry to see another example of less and more than 180 degree shutter.
- So when it comes to me taking video on my DSLR I'll likely choose FPS and its default shutter speed, and the really use aperture and ISO as the variables to get the right exposure.

If you're getting started with a new pool, here's what you need...
After taking care of my pool for 1 year (came the with the new house), here are some of the key things I needed:
Chemicals I use regularly:
- Taylor Complete Chlorine FAS-DPD Test Kit - k-2006
- Video showing how to test well in general
- Video demo showing how to read the tests (key!), click on the POOL / SPA link on the left under LIQUID KITS
- Picture showing what the final cyanuric acid result should look like
- Alternate detailed instructions for the test kit
- Taylor Speed Stir Magnetic Stirrer 9265
- Decent website for purchasing pool chemical supply stuff: www.sunplay.com
- Online pool resource website: www.troublefreepool.com (these people know they're stuff)
- The above website's getting started section: Pool School
- Is a higher free chlorine level safe if the CYA levels are high?
- Article on another website covering this issue at a high level
- Two charts showing cyanuric acid levels and the corresponding free chlorine levels needed
- Simple
- More in depth (covers mustard algae)
- The EASY online calculator to use when determining how much of what to add: poolcalculator.com
- The key to success on this website is configuring it properly the first time:
- Enter in the size of your pool in gallons
- Scroll to the last row (yellow) and make selections in the three pull down menus (I use TroubleFreePool.com, Bleach (liquid chlorine), and Plaster).
- Go back to the top of the page and in the yellow Free Chlorine section make sure to change the % bleach item from 6% to 10% if you're using standard pool store liquid chlorine/shock.
- Then enter in your current numbers and desired numbers and hit calculate.
Chemicals I use regularly:
- Liquid chlorine
- Power raises calcium hardness over time
- Tablets raise CYA over time, both are VERY hard to get rid of later on.
- Store in cool, shaded place. Doesn't lose potency if used within a month (according to a site I recently came across).
- Muriatic acid (to lower pH)
- Polyquat algaecide when I feel like it to prevent algae growth if it gets really warm
