Hey everyone! Can I ask for your help with a little test?
I’m trying to design a measurement target for focus reach (aka centimeters to blur) that uses edges of specific colors, but I’m not sure how easy or hard this is to see for most people. If you use Differentials / computer glasses, or have a natural blur horizon around screen distance, could you please have a look at this image:
If you try to find your edge of blur with this, in theory, you should be able to see that it’s closer for cyan (FOCUS) than magenta (REACH), as in, magenta blurs earlier when moving back. But I’ve run into people who say they can’t see this. Which obviously is bad for trying to use it as a standard. So I’m wondering if it’s just the odd person without proper computer glasses, or if this is hard to spot for some reason.
How do the two lines blur for you as you check your edge of blur with computer glasses? Please try both eyes individually if it’s inconclusive.
- The magenta clearly blurs earlier.
- It’s hard to notice, but I think magenta does blurs earlier.
- I can’t tell whether the cyan or magenta line gets blurry first.
- I think cyan blurs earlier.
- I don’t have the undercorrection for a screen blur horizon.
- None of the above
