I recently got into photography and use a Nikon D3400. I have started shooting in Aperture Priority and Manual modes about 2 weeks ago and I noticed something strange regarding the ISO. When I am manually setting it, it starts from 100 and then the values keep doubling. If I switch over to Auto mode however, I get photos with odd ISO values, like 360. Is it at all possible for me to set an ISO value, for example between 400 and 800? If not, why does Auto mode seem to have more control over the ISO than the other modes?

Not on the D3400. It is on higher end cameras.

Because Nikon decided to implement it this way. The are two arguments for this, both of which are probably somewhat true:
- The D3400 is an entry-level camera and as such it makes sense to keep the available options as small as possible. More options give more settings for beginners to mess up.
- Restricting the D3400 to only full stop ISO settings gives another way for Nikon to differentiate between their low end and high end models without fundamentally changing the hardware. Therefore they make more profit.
(For avoidance of doubt, this isn't an anti-Nikon rant; Canon definitely do the same thing, Fujifilm do something similar with shutter speeds and I suspect other brands do the same as well).
