Yes, no complicated or precise math is needed. This has always been an 'issue' - even with film a photographer had to photograph 'a little too much' so that s/he could make necessary adjustments.

Yesterday I had to deliver my wife to a conference in Chicago, so we decided to spend to the earlier part of the day at The Field Museum, which was originally financed by Marshall Field, a very successful Chicago merchant.

Like most museums in Chicago, the 1921 Field Museum is located on parkland between the city proper and the lake. City planners included lots of parkland when they rethought the city after The Fire.


I took this view of "Stanley Field Hall" later in the day, as they were preparing for a big event. The blue circles on the floor show where Sue the T-Rex will eventually stand.


These days the museum seems to be more anthropology than anything else. While waiting for my wife to finish reading her way through the how-people-came-to-the-Americas exhibit, I engaged in some people watching.


One of the hallway displays is of meteors. The table in the background features a small one from Hamlet IN, an aptly named town near to where I live.


All these museums seem to be fascinated by the orient.


And these days, right-thinking people who talk about China will give equal time time to Tibet.


I'm guessing these bronze figures were more valuable to a previous generation of curators, but today they're in the middle of a basement hallway near the cafeteria.


Even though dinosaurs are a minor part of their collection measured by allocation of floor space, it is a major part of their marketing to kids {duh}

The answer is very simple. People like rectangular images. Lenses must be cylindrical because of physics - light would bounce off flat edges, creating funky design issues.

Actually, the pixels come from a square on the sensor. The way the sensor is designed, every square will have 1 red, 1 blue, and 2 green pixels.

May want to do that earlier. In 1992, my wife and I, with our 5 year old and 1 year old daughters, left Muir Woods area, heading for Los Angeles with those "plans". Our intention was to make the trip in two days. We started looking for a room early afternoon. We finally found space in a luxury hotel - at half price because it was so late ...... on the outskirts of LA!!

InBody Image Stabilization works just fine for Pentax.

In this part of the country we call 'Michiana', because its kind of in both states, we understand.

The problem with cheap brands like Wolverine is that they're just cheap cameras mounted on a cheap stand. Every review I've seen says the true scanners, such as the one manufactured by Plustek, are much better. My personal experience is that you need mutiscan + specialized software to deal with surface defects.

And right there you have much of the answer to your question. I don't know about where you live, but most of us don't live on land measured in acres; I lived on 0.75 acre once, but in was in Kansas where animal diversity is low, and subdivision rules severely limited what we could do with the land. Right now we're living in my mother's house - tiny fraction of an acre, but it abuts on a ridge carrying the local bypass, and I've managed to make it a place hospitable to squirrels, deer, birds ...... and cats, but next year we will have to settle the estate and go back to how many live, in an apartment where the wants of the majority will result in a neat, sterile environment.

1. No point - I don't have 3D vision
2. No {see #1}
3. No
4. I've never though about it.

This evening, my wife and I attended a Musical Revue, called "Extraordinary Women", at nearby St. Mary's College. I wasn't thinking photography, which is usually specifically banned at such an event, so the only camera in my possession was my Nokia cell phone, and my wife picked a table, in a front corner, only because she could see the stage, albeit from a very sharp angle; however, it turned out to have several good photographic sight-lines, and that turned out to be important when the first words spoken by the narrator were an invitation to take pictures - and to post them on the Internet - so I did the best with what I had. Incidentally I didn't notice any other person taking still pictures, and only one taking occasional video. My one issue was the LED light-stands they had scattered along the walls; I could not get a good image if one of them was shining into my lens, so that was a major limitation of directions I could point my camera. Those LEDs were the major cause of the funky colors you see in my images.

The show consisted of words about how women have been portrayed on stage and screen over the years, with performers demonstrating. The performers sang from all parts of the room - with very little happening on the stage - but as I said, we had several sight-lines, while many of the tables had tables {with people} in every direction.

My phone creates 16:9 images with a view equivalent to that provided by a 28mm lens on a 35mm camera; I did plumb one image slightly, but the only other editing I did was to crop them to 3:2. On all these images, the aperture was wide-open at f/2.4, but that provided plenty of DOF on a crop 7.0 camera like this. I have included other data from the pictures, because I found decisions made by its automation to be interesting.

But, if you don't already have fancy software, my naming scheme works just fine

The camera should just slow down if that is the case.

The 24mp APS-C Pentax K-3ii also has that capability for a little less money.

Early during my time here, someone here asked how a particular body, lens combination worked; I had just taken several pictures with that combination, so l posted them. Immediately another newcomer blasted me for posting "snapshots". I had been well-meaning - but not very useful since I didn't know about "(save original)" - so I've just "kept on trucking".
