I am not sure I understand your question.
Are you talking about the Exposure Compensation as mentioned on page 65/66 of the User Manual?
The purpose is to set the Compensator to favor over or under exposure if the camera consistently turns out pictures that are over or under exposed. It is not set automatically, it is set by you. It can be adjusted in 1/3rd f/stop increments.
Normally it is set to zero.
It comes in handy when taking pictures at the beach or with snow as they tend to turn out overexposed.if you are shooting in Auto.Mode.
Good afternoon. I am brand new to photography with any thing other than an iPhone. I just purchased a Nikon D5200 kit the other day. I have been playing around with it for a couple of days now and absolutely love it. I am definitely hooked. I have spent plenty of time searching, but have a couple of questions I was hoping someone with experience with this model could help me out with. I have also read the manual about 10 times The lens I am using is the stock one that came with the kit - Nikkor 18-55 f 1:3.5-5.6 I believe.
1. I notice that with the camera in auto - the exposure meter will routinely show underexposed (digital meter readings to the left), but never to the right to indicate overexposed. Is this normal? Even if I am outside and point the camera towards the sunshine, I can't get it to indicate overexposed at all in auto. I know the meter/display does work because in manual I can adjust the settings and it get it to show overexposed. Is this just a function of this specific lens/auto setting. Again, I am new, but want to make sure the camera is functioning as expected.
2. I took the camera outside today and it instantly fogged up because it's 70 inside and 95 outside...I didn't stay out for long because it is crazy hot, but is there any danger of doing damage to the camera when going between environments like this? I assume the answer is "no" but figured I would ask the experts.
Thanks for your time!
