i can read, i accept what nikon presents in their chart as gospel.
Frame a subject so it totally fills the 1.3 mode.
What is the area,, how many pixels does it use?
Without moving anything, shoot the subject in normal mode and crop the image so the subject totally fills the crop.
Whats the area and pixel count?
Now we have two similar images and guess what?
The area and pixels and resolution and image size are all the same as they were in the 1.3 mode..
Choosing the 1.3 mode did not reduce the resolution.
Told you he would never get it, now he want's you to crop the FX mode to the DX mode (or similar on the D7100 to 1.3), Nikon never said anything about physically cropping the DX image to make it the same size as the 1.3. He doesn't understand resolution period and he never will.

On Page 68 of the D7100 owner's manual, Nikon has a chart. This chart shows choices for Image Area. The two areas shown are DX (24 x 16) and 1.3 x (18 x 12). The chart shows 3 Image Sizes (Large, Medium, Small) and for each of the Image Area choices it lists the number of PIXELS at every choice. The number of PIXELS listed at the 1.3 x choices (large,medium,small) is always LESS than the comparable DX choice. So ... at any print size, the number of PIXELS available is always less at the 1.3x Image Area choice.
If you produced two prints of the same size (which I believe you did) but one had fewer PIXELS, what word would you use to describe the difference between the two?
What it comes down to is A PIXEL IS A PIXEL IS A PIXEL. But if you have fewer of them to record detail, ... guess what suffers?

You've got it backwards.
To get the "Telephoto Effect" the normal image is not being cropped down to fill the smaller 1.3x area. The pixels in the 1.3x area area are being enlarged to fill the full size area. THAT is the "Telephoto Effect".

I gave it one more try ... after that I will give up.

you don't have to crop anything.
if the normal image is a house with a small door and the 1.3 shows only a small door, the resolution of the house and its door, in the normal mode and the door shown by the 1.3 shot will all be the same.
No crop required, it just made measuring area easier for me.

If the "Normal image" was of the WHOLE HOUSE and now you enlarge the DOOR to the size of the HOUSE (THE TELEPHOTO EFFECT) ... guess what suffers?
By definition of resolution you are wrong. There is more information contained in 36mb than in 24mb period.

resolution is the smallest element a camera system can distinguish as being seperated from some other element.
A larger sensor area may increase the number of data points you can record but it does not improve the resolution just by being bigger.
Resolution
The resolution of a surveillance camera's image is measured in the number of pixels contained in the image. The higher the number of pixels, the more detail in the image. Higher resolution images give you the ability to zoom into the image to see fine detail.
Typical Resolutions
VGA: 640 x 480
D1: 720 x 480
Full D1 (FD1), 960H: 960 x 480
720p: 1280x720
1.3 MegaPixel: 1280x1024
1080p, 2.1 MegaPixel: 1920x1080
3 MegaPixel: 2048x1536
5 MegaPixel: 2592x1920
6 MegaPixel: 3072x2048
Counter that definition with any quote that changes this definition from anywhere on the web and show where you got it.

Wow I can't believe you resort to microscope definition to equate to a camera resolution. Makes absolutely no sense in determining size and resolution in camera technology show me the same information as relates to camera.

there is no difference, all the same animal whether we measure it in the electrical, mechanical or optical domains, its still just resolution.
thats what i just did.
search term:
"what is resolution?"
Read page after page, never did see sensor area or megapixels mentioned.
So with this statement:
Digital Camera Resolution
The amount of detail that the camera can capture is called the resolution, and it is measured in pixels. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or "grainy."
What you are saying is the same amount of pixels exist in 36MB as in 24MB image, gee if that is true I might as well sell my D800 and D810 and stay with my D7100.
