"Image Size" (Page 2): Many cameras allow you to save the settings to a file on your camera card. That enables you to quickly set your camera to the desired settings fairly quickly...

Many cameras allow you to save the settings to a file on your camera card. That enables you to quickly set your camera to the desired settings fairly quickly (although you have to work through the menu to do so). There's a two-button reset to change all your settings to default factory settings. That you can do in less than a second.

I have thought for years that it would be a great help to have the camera provide a place in flash memory to store your settings rather than saving them to the card. After all, when you reformat your card, it erases your settings.

Having them in flash memory would allow the camera to define a two-button reset to restore your personal settings, similar to the reset to restore the factory settings. This would save a lot of time. Even better, there could be a menu item that would restore all your settings at power-up. That would mean that every time you changed a setting you wouldn't have to remember which setting you changed, and change it back before putting the camera away or even before taking another shot.

So far I haven't heard of any camera manufacturers acting on my suggestion although I have posted it on several forums and tried to spread the idea around.

In earlier post you said..
"Crop sensor format, not larger image. (.8)
And what then should +20% be misconstrued as?"

1/1.2 = 8.333

So .8 is not the reciprocal of 1.2.

1/1.2 is NOT 8.333, it's 0.833, eh ?

That's quite a math debate. I believe all Jerry really wanted to do is advise you not to accidentally move the "QUAL" button to a setting other than FX.

Isn't photography fun!

Very good point. If photography was not fun we would not do it. Pixels and file size math is always a hoot.
Camera button is the problem. Thanks.

"Image Size" can mean a lot of things, but to me, it was a surprise. While processing some pictures I took with my D750, I realized that there was less room around the edges than what I shot. When I pressed the Menu button, I saw that "Image Size" appeared immediately. Apparently, I somehow changed the image size from full FX to 1.2. I've never done that intentionally, but there you are. Something to keep in mind.

Hi Jerry! I have a D600 which has changed settings from FX to DX on 2 separate occasions in the middle of using the camera. I have no explanation as to why.

Thanks for the table. It proves what I've been saying about using the DX setting, that a 24MP (6016 X 4016 large, pixels) sensor when used in DX (3936 X 2624 large, pixels) = 10.3, or drops to ~10MP, less than 1/2 the pixels!

You could have image area assigned to the Fn button, The Pv button, or the AE-L/AF-L button. Holding one of the buttons down and spinning the main command dial will change the image area.

Thanks....I will check the settings. I have never used DX so I know it wasn’t done purposefully.
‘‘Tis a puzzlement!

One of the main uses of this "image size" feature on a Nikon
is the use of a "DX" (APS-C) lens on an "FX" (full-frame) camera
such as the D750.
I used it recently (on purpose 😉 ) when using a "DX" lens
on the D750.
The drawback is that the image is only 18 MP instead of 24 MP
because you are only using 2/3 of the image sensor.

2/3 = 0.66666 x 24 MP = 16 MP 2/3 x 24 = 48/3 = 16 The reciprocal of 2/3 or .66666 = 1.5. 24/1.5 = 16

1.5 is the crop factor for Nikon

Oops- you're right, it is 16 MP, not 18 MP.
One of the hazards of late night posting!
