Tech Tuesday: Why Digital Camera Images Aren't Sharp Out of the Camera

When I was scanning the web for ideas on this weeks' Tech Tuesday post, I ran across this already-made-up excellent explanation of why digital camera images are not sharp right out of the camera. You can see it here at Ken Rockwell's excellent web site. The technical reason is something called Bayer interpolation, which Ken explains very well, or at least in more than enough detail for me.

It tend to check in with Ken's 'What's New' section at least every few days - he usually has something interesting to say or to explain, and I like his humorous writing style.

I got away without writing my own Tech Tuesday post today, but I guess I can't get away without posting one of my own photos. How about this one, from our photo meetup this past Saturday at Arlington National Cemetery?

Arlington National Cemetery Meetup

 

Our hyperactive Meetup group visited Arlington National Cemetery yesterday, our sixth photo meetup since we got started August 2nd.

I can tell you from my experience over the past two months that if you find yourself in a photo slump, try a nearby photo Meetup.com group - it's worked wonders for me, as I've been photographing nearly nonstop since early August. The energy from being around other enthusiastic photographers carries over between meetups.

I hadn't been to Arlington National Cemetery since 1964, when I was 14 years old. I was moved by the changing of the guard ceremony at the Tomb of the Unknowns, but not so much by the ceremony itself, as by the many WWII veterans attending. While most people were watching the precise ritual by members of the 3rd US Infantry Regiment, I was fixed on these true American heroes. As young men, they endured countless hardships for our sake, then came back home and quietly and modestly rebuilt their lives as well as the American prosperity of the postwar period. Now at the end of their lives, we are fortunate whenever we find ourselves in their presence.
