Thank you for the addition and correction. My memory was fuzzy regarding the card bit.
Thanks for the clarification. When shopping for a newer Nikon body, Ive ran into more confusion...Different types of sensors, different size and pixel count. Different pixel count vs pixel size, various sensitivity. If your options were a D-90 or a D-7000 (7200, 7300?),what do you compare to make a decision?No, you need a Custom White Balance for all images in dentistry. It's the Custom White Balance that makes the images color accurate. Jpeg or Raw.
There is a program - inside your camera - that is used to create a Custom White Balance, for your jpegs. That adjustment (Custom White Balance) lives inside your camera and is applied to all your jpegs during image capture.
In short, your camera (image sensor) has no idea about the lighting source. This is the reason most all digital cameras ship with Automatic White Balance as the default.
With raw files, the custom white balance is applied by Adobe Photoshop Camera Raw/ Lightroom in post processing.
How do you feel the 85mm nikkor VR macro compares on just tooth shots?in short, I like full frame sensor bodies. Nikon D800E/ D810. These bodies are also sharper without the anti-aliasing filter. This is a distinct increase in image sharpness.
The cropped sensors are fine - it does mess up the 1:2 and 1:1 settings on the lens barrel. Full frame sensors makes those settings on the lens correct.
The best for Nikon is the 105 mm Nikkor VR. The lens choice does make a perspective difference in full face shots. (85mm lens gives a small fisheye look to faces) The longer lens is better for face shots - as the faces look more natural.
Pixel count isn't important really. Large format printing is the advance for larger pixel count cameras.
