Settings for Shooting RAW Format @ 20 megapixels on D800

Hello everyone,

I believe I have the answer to the following question but I just want to confirm with fellow D800 users.

After reviewing the user's manual, it appears that if one desires to shoot 20 Megapixels in RAW format, the "image area" needs to be set at 1.2x and not FX. Is this correct? So if that is the case, that means I'm not actually shooting "full frame" and the sides will be cropped and also the "crop factor" will apply. So if I'm shooting with a 50mm lens, I'm actually shooting 50mm x 1.2

My original intention was to set the "image area" to FX (based on the menu settings) and then set the "image quality" to "RAW" hence 20 megapixels. However, this doesn't seem possible because the "image size" is greyed out in the menu when trying to do the following:

1. Image Area = "FX"
2. Image Quality = "RAW"
3. Image Size

Am I understanding this correctly or perhaps I'm doing something incorrectly? Any help, explanation, would be greatly appreciated.

Thanks everyone

If you want to use the full frame (FX) then your only options are 12/14 and compression level. You cannot choose a smaller RAW file size.

To to clarify, I can only shoot 36mp in FX mode and use either 12 or 14 bit. Otherwise my only other option is reducing the "image area" by choosing 1.2x thus the ability to shoot @ 20mp but also sacrificing full frame and enabling "crop factor" mode (which means not everything I will see in the viewfinder will be captured.

To clarify, it's impossible on any Nikon body, past and present, to have any RAW picture with reduced resolution except in a crop mode.

This cannot be remedied with any setting, because it's just impossible.

What on earth are you trying to do? More importantly why? Just shoot in FX and if you want less of an image, crop it in post. If you want a smaller file size choose Lossy or 12 bit. I'm not at all sure why anyone would want to lower the resolution of this camera to 20 mpx, but go ahead.

I think it is smarter to shoot maxed out. 36 megapixels and compressed lossless RAW. Then, if you wish something smaller, go ahead and do that in your computer. You can always throw away pixels. You can't add them after the fact.

Why not consider a different camera too? A nice D7000 has a higher pixel density and more manageable file sizes if that's a problem. You get a 1.5 crop factor and what you see in the viewfinder is what you get. It seems to me you're trying to make a D800 into a D7000 for some strange reason. Help me to understand what and why you want to do what you're asking about.

FYI, I believe 1.2x crop mode is 25 MP, not 20.

There are also indicators in the viewfinder for your crop settings so that you can compose your frame and not lose anything.

I am a 4 years late, but according to Nikon full 36 x 24 sensor use resolutions do include a 36MP, 20MP and 9MP sizes for Large, Medium, and Small resolutions respectively.

Why not resurrect a 4 year old thread. The L,M,S sizes refer to the resulting in camera JPEG mp count when converted in camera.
