yep, but all the moisture in your breath is wet wet wet and it will condense upon any surface within the tent.
Alright, don't take silica gel. Your kit.
I understand your concern pablo. Inside the tent overnight is a good point. The problem with silica or other humidity control devices is that they will be saturated in no time and be of little use. The environment will overpower them very quickly and then they are just extra weight.
In general, if the camera is in the same environment that everything else is, it's all equal and condensation rarely forms as long as the camera isn't suddenly moving into a much warmer or more humid environment. The overnight inner tent environment is an exception which is why the camera stays outside of my inner tent under the vestibule if there's a possibility of condensation. In the dryer climates this isn't much of an issue though. Also, one can always keep the camera in a ziplock bag overnight inside a humid tent to prevent condensation and not remove it until the tent has been opened and ventilated.
Whatever the case, a good understanding of what causes condensation and how humidity works will serve one well in determining what is needed to prevent moisture problems.
