@kfield: Dang, if when they came back in they were still out of focus! We concluded that there was no other explanation other than that there was something screwy with the photographer's vision.
This reminds me of the French Impressionist painter Claude Monet. He painted a lot of the same scenes over and over again through the years. The thing was that he had cateracts that grew worse with age, and his paintings reflected this in several ways, including loss of focus and detail and changing colors. From the Internet:
"He did not perceive colours as intensively as before, which initially made him chose significantly stronger hues of blue and green shades as the weaker shades were filtered out by the yellowy cataracts. Red shades appeared dirty to him, pink insipid and he found it hard to differentiate between similar colours."
I have a funny photographer story to share: Years ago when I was working for a print publication (I know, that dates me back to the dinosaur age) we contracted with a photographer in another city to take the cover photo. When the photos came in, we were weirdly surprised to see the photos were out of focus. No, we weren't trying for the "soft" imaging known in some industries, but it was quite peculiar. So we contacted the photographer to express our displeasure and asked him to retake the images. Dang, if when they came back in they were still out of focus! We concluded that there was no other explanation other than that there was something screwy with the photographer's vision.
I also hastened to comply. Inquiring minds would like to know however, why I need to have a phone number in my profile. Fortunately I have a number that I use for such purposes. Not sure why I woild want to answer a call from EETimes unless they want to know where to send the check. And I already entered the address for that...
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
