So generous people; thank you for your time.
I visited the camera store and we discovered that my camera lcd was set to the maximum brightness level which completely distorted any understanding of my exposure. What I now see on the lcd in terms of ligt and shadow is very similar to what I see on my computer screen.
Maybe you can shed light on this:
I also may need to just upgrade my imac. On the camera store's late model imac my images were tac sharp but on my imac they look quite soft and still have less light.
There is also still some difference in terms of color settings. My camera's colors have a brighter pinkish tone and on the camera store's imac and mine the tone is yellowish orange.
I will try DPReview and Nikoncafe. My first step is to reset my cameras to factory defaults and then upload and compare.
Thank you both for your help
