Auto White Balance Settings for the Panasonic GX1

Recorded on March 22nd, 2014

I’ve been driving myself crazy trying to nail down the auto white balance settings on the Panasonic GX1. I kept getting too much of a pink/magenta cast, no matter what I tried. I shoot in RAW for now, and I know I can tweak all this stuff in Lightroom, but I’d rather mess with white balance as little as possible in post-processing. After doing some test shots this morning, I’ve settled on using +4 amber, +4 green in the tweaked AWB settings. This appears to work well for outside light. I may have to start all over again for a setting that works in incandescent light. And who knows how well this will translate to skin tones.

Also, I use the GX1 Huelight camera profile, which by itself gets really close to what I think the colors should be, but the +4 amber/+4 green setting helps even more.

I’ve listed the test shots below, following the format that “+4 amber” means “4 clicks to the left of the zero axis, towards Amber”. The first image is the most natural, I think.

+4 amber, +4 green: +4 amber, +4 green

+3 amber, +3 green: +3 amber, +3 green

+2 amber, +2 green: +2 amber, +2 green

+1 amber, +1 green: +1 amber, +1 green

+0 amber, +0 green: +0 amber, +0 green

+2 amber, +4 green: +2 amber, +4 green

+4 amber, +2 green: +4 amber, +2 green

+6 amber, +6 green: +6 amber, +6 green

+8 amber, +8 green: +8 amber, +8 green

+9 amber, +9 green: +9 amber, +9 green

Moving to Statamic

Recorded on March 18th, 2014

When a person changes their blog back-end, they are obliged to write a short post about it. This is that post. After having various seldom-updated blogs that ran on WordPress on Dreamhost and sometimes failed to load, I bought a license for Statamic. The appeal of Statamic is that it runs on text files and PHP. No database to get bogged down when your shared server runs low on resources. This way I may have a somewhat less-infrequently updated blog that stays available a much higher percentage of time.

The theme you’re looking at right now is Acadia, and I haven’t tweaked it one iota. I even left all the sample sidebar links on in the interest of just getting this thing live and starting to write again. I once read something somewhere about “If you weren’t embarrassed to launch, you waited too long”. I’m a little embarrassed, but glad to start fresh.

AirPort Extreme Slowness

Recorded on April 15th, 2013

We got a 5th generation AirPort Extreme a few months back. Until now, it had lived up to the claims of super-easy setup and low maintenance that some of my favorite bloggers (like Eddie Smith) had promised it would deliver. But recently, and pretty suddenly, the wifi connection to our iOS devices had gone to pot. Web pages barely loaded, the iOS App Store became so slow that it was unusable, and podcast downloads would time out on Instacast. Rebooting the AirPort didn’t help. Neither did updating its firmware.

Other people seemed to have similar problems, and suggested it was something wrong with the way the router automatically picks channels. Using the AirPort Utility, I found that the 5GHz band was auto-set to channel 149, and the 2.4GHz band was on channel 1. I don’t know if there’s really something fundamentally wrong with the channel-selection algorithm, but I changed both bands to be manual, and changed to channel 48 on the 5GHz band, and channel 11 on the 2.4GHz band. The speed problem seemed to go away immediately.
