Canon 6D - how to fast forward and rewind video

It wasn't clear to me at first.  You select the frame forward or back icons and then hold down the Set button.  The longer you hold it the faster it goes.

Two apps that caused the Samsung Galaxy S4 camera to fail

I'm not sure which of these two apps caused the Samsung Galaxy S4 camera app to fail, but when I installed them the camera didn't work.  When I uninstalled both the camera was fine again.  So it's one of these two apps (both for language learning):

- Obenkyo
- Rosetta Stone

How to work around HTC wifi bug

There's a nasty bug on HTC phones that have to interact with EAP authentication.  You enter in all the information but the Connect button never lights up.  The only way to work around this is to choose the wrong authentication protocol and when it fails, go into the profile and hit modify, then the Connect button enables.  Yikes!

DSLR and shutter speed

What I got from this blog:
http://tylerginter.com/post/11480534977/180-degree-shutter-learn-it-live-it-love-it

and this blog:
http://www.canon5dtips.com/the-basics/the-effects-of-shutter-speed-control/

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:

  • 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
