Different camera bodies.

[Don R]

I am a member of the Nikon Australia Facebook comunity. I have just put this onto their Facebook page. "I don't see how anyone can tell if a picture is taken with one camera rather than another. Nobody can tell the difference between a picture taken with a D3300 and the same picture taken with a d7500 using the same lens. They are the same." I await the comments.
What are your ideas on this?

When viewed at a standard format so not at the extreme, where a difference in rez will possibly show or as long you’re not shooting in extreme shooting scenarios you won’t see much of a difference between a D7500 and D3300

I would have thought that any picture on Facebook could be taken with just about any camera / lens combination. What brought this up was someone wanting to see the quality of pictures taken with a D7500 camera. I wouldn't think there would be any noticable difference in any of the photos.

I understood your question regarding the possible visible difference in quality between both sensors and you did put that question on a FB page. LOL.
For FB a smartphone camera will do.

The D3300 lags the D7500 in dynamic range. All things being equal you may see a bit more noise in the dark shadow areas of a D3300 image compared to the same image from a D7500. If it's a well-lit image shot at a low ISO I think one would have a hard time seeing a difference. The difference would become more visible in images made at high ISO settings.

I took 2 head & shoulders pictures of my Grandson within 5 seconds from each other. Indoors and lit from a large floor to ceiling window. I took one, put the camera down, picked up the other camera and took the second. Both shot with same focal length, both on auto WB. When I compare the 2 there is a slight WB difference that stands out to me but most people can't tell the difference.

Camera 1 was a Nikon D850 with a 50mm f1.8 lens, the second was a Fuji XT-2 with the kit 17-55 lens set to 35mm.

What do I think of this? I expect different cameras to get great results in average conditions. I expect higher spec cameras to get great results in difficult or very difficult conditions.
What I don't expect is that spending more money on a camera will improve the picture quality of the final result in average conditions. As soon as you add low light, subject moving at high speed, and other variables in the shooting conditions you need a higher spec camera.

DR is not the same as signal to noise ratio.
DR is ‘just’ the ability of a sensor to catch shadows and highlights while keeping detail nothing else.
SNR however is the ability of a sensor/camera to keep the signal clean when amplifying it. (Dialing in higher ISO)
According to DXOmark the difference in lowlight performance is 100ISO between the D3300 and D7500.
(The difference in DR is about a stop but since both cameras are well above 10EV it’s not that important.)

Nonetheless a larger dynamic range is always preferable because it allows for a higher signal-to- noise ratio, but it is not guaranteed. SNR will always be less than the dynamic range because it is limited by the noise in the image and is not always maximized due to challenging lighting conditions, exposure time limitations, and the choice of optics.

I agree. A picture in normal daylight, something like 1/250 f8 iso 200, wouldn't look too much different I would think especially on Facebook.
