Monitor gamma, cont.

Posted in Uncategorized on February 20, 2010 by jedreynolds

A very fundamental idea wandered my way on the topic of adjusting my digital photography work-flow for … anonymous (for lack of a better term) monitors. These monitors have not been adjusted by anyone, likely. Their settings typically would reflect little more than entropy. Do I care for all my work to look good on any monitor? I shouldn’t…it’s not worth my time. This explains why many photography web sites have a gray-scale on their doormat. If someone really wants to enjoy my photos, they need to adjust their monitor in order to appreciate any photo. Otherwise, I should only ever compose images in the Netscape color cube–256 colors.

Some basic monitor adjustment. And more basic monitor adjustment.

To enjoy your world more…please adjust your monitor.

Wildly Varying Monitor Gamma

Posted in Photos with tags , , , , , on February 19, 2010 by jedreynolds

With all my recent photo work, I’ve started developing an eye for how my photos are looking on different monitors. I have an LG monitor at home for which I have a ICM profile for. I can get Ubuntu to load this profile using xcalib. At work, I have two Viewsonics that don’t live on viewsonic.com anymore, and there are no model specific ICM profiles available for them to download. So on my recent Ravenna Tree Sign picture, the Viewsonic monitors displayed that picture distinctly darker than my home monitor. I upped the gamma setting on my viewsonics to 1.50 (?) using the on-screen-menu. However, this is all very vague–using on-screen menus isn’t necessarily the bees knees. This leads me to wonder: What is a typical screen gamma?

According to this ancient discussion on monitor gamma photo.net, Macs and PCs have an entirely different default range, 1.5 for Macs, 2.2 for PCs (Windows). Apparently this lead to a development of storing gamma-hints in picture formats(?) First I’ve heard of this. However, here is an interesting monitor gamma dipstick posted in that thread:

Monitor Gamma Dipstick

On an LCD monitor, moving your head around makes the gamma value change. So if I tilt my monitor up to be more perpendicular to my line of sight, I change the apparent gamma from 1.65 to 1.35. Wow, looking at the picture in this html editor, it’s now 1.05. I think if someone were to pay me to do this stuff, I think I’d probably stop using an LCD to do color managed work. (Are there good LCD monitors for color managed work?)

If you have trouble viewing my pictures, or if you think they are too light or too dark, let me know. I’m not going to get a colorimiter (a Color Spyder) for my home monitor anytime soon, but if my home monitor gamma and brightness off the tracks, I want to know.

Tree Sign, Ravenna Park, 2010-02-15

I’ve walked by this sign in Ravenna park for years. I’m guessing it used to be a yield sign. Now it’s a macabre symbol that reminds me much of the art I produced in middle school.

I was surfing around looking at campsites tonight. Suggestions appreciated. If this February is a sign of what May will be like, I’m all for it. Consider how vivid these blossoms were in January. Any places you like to camp? Please share.

This was a brief experiment tonight doing a “dissolve filter” and a mask. The unfocused background was kinda distracting because it was a lot of lens-circles. I blurred out the whole layer and masked the foreground out of it, dissolved it in and threw a “soft light” to rebuild the color on the blossoms. If you’d like a print of this, please ask.

Simple LDL Measurements Are Meaningless

Posted in Health with tags , , , , on February 16, 2010 by jedreynolds

Recent research shows that different types of LDL pose different risks.  I hadn’t know previously that LDL was classified by “small” and “large” particles. However, lots of articles that have been published through the Weston A. Price Foundation journal Wise Traditions have long claimed there is no correlation between high LDL and heart attack risk. There is agreement that low HDL and high triglycerides are a clear risk.

Now consider that the high-carbohydrate diets we (as a nation) are putting into our kids raises their LDL…and doctors want to prescribe statins to children! Are we just blindly handing Big Pharma our money and our health?

I like the texture of the bricks and I knew I could bring out their color.
