A quality Nikon camera under $300?

So I saw I was really interested in doing photography lately on my iPhone 5s and I wanted to do something more practical than taking them on a phone. I was looking at Nikon cameras which I prefer over any other, I also want really nice HD pics with lots of cool filters and effects, I'm not crazy about having the best zoom in the world but quality zoom is preferred, and I want one with lots of space for pics AND video. I do want one preferably under $300 and over $270 is a bit much for the budget I have but please help I don't have experience with cameras much🙈

How to film from my Nikon but show up on my Macbook Pro?

I want to film a video for my YouTube channel but I want to be able to see what I'm filming, whether the camera is focused or not and whether it's in a good position for the lighting to be good. I want to know if there is some way I can hook it up to my MacBook Pro so that I can see what's filming on my Mac without having to use mirrors to see what's on the camera. Is there a special lead I need to get or is it something I have to do in Final Cut Pro X? Cheers.
Added (1). It's a Nikon D3300 and a Macbook Pro.

What DPI is okay for large scale printing?

Hello, I have recently displayed some of my photography in a gallery for the first time. I only printed relatively small prints at 300dpi which with my 18mp camera was around A3 size. I know the best resolution for print is 300dpi but many other exhibitors images were huge A2+ sized. With my 18MP camera or in fact even a very high end Canon/Nikon SLR that has a similar number of MP it would mean printing at around 200dpi or lower for A2+ sized images.

My question is how low can I go with the dpi? I understand in a gallery you are viewing them from a distance but even so these huge images were still quite sharp close up. I guess they may have been shot with a film camera. I would experiment with sizes if I had a large scale printer myself however it costs a lot to get a large print done so I can't afford to experiment, it would be nice to have some opinions from fellow photographers.

Thanks in advance.

Tips for black & white / monochrome photography?

I have really gotten into monochrome photography

it seems to me that not all of the same rules would apply given there is no color obviously

but just wondering, what are some b & w photography basics / tips?

my D7100 calls it "monochrome" under picture control settings yet a b & w" message blinks when i am taking the picture, so apparently Nikon does not recognize any difference between the two, just wondering if you can?

Speedlight for Nikon?

Hi, Im looking for a Speedlight for my Nikon camera since I do portrait photography, but I cant afford the really expensive SB-800s and so on, so I looked around and found the Yongnuo YN-565EX. However, it said "for Nikon SB-800, SB-900, etc". Does this mean it has to be the slave for an SB-800 or such? Or can I use it on the camera on its own. Thanks
