Originally posted by Lowell Goudge this may seem a little over the top, but why not add the following.
you show the area (for example at 10 feet) which I assume is really meant to be the area for the case where subject distance is much greater than focal lenght (much greater usually means an order of magnitude or more). I have no problem with this, and my first suggestion is to add one more line to the calculations. the area (in either square inches or mm) of one pixel on the sensor. Also you could put the linear distance between pixels. Therefore you would need to have the sensor size also (6.1, 10. or 14 MP)
These points althoug simple would allow people to appreciate the ultimate resolution of the system.
Lowell, correct me if I'm wrong but you'd need to have the full sensor specs in order to do those resolution calculations "accurately"? You would need the actual size of each pixel as simple resolution (pixel count) wouldn't quite get you there. I'm also not sure how to relate that to the film columns.

image size = subject size * focal length / distance.
people often forget this when shooting with long tele's
Not sure what you're asking for here. The FRAME SIZE row tells you how big a subject will fit in your frame at a given distance, and the IMAGE SCALE tells gives you the ratio of image to FOV - but it seems you're after something different?
Originally posted by Ron Boggs As you neared completion of this great resource, did you find that you needed to increase the volume and frequency of the machine that goes PING? That seemed to be an important factor for the Pythons when they used the early versions of the PING machine.
Nice work...
Ron, you will have to submit requisition form BA-1100-N in triplicate to the Department of Redundancy Dept. for that information; you'll need to have a valid ID-10T card as well.
And thanks
