Can I hook up an LCD screen to my digital camera?

I have a digital camera that takes amazing video and sound quality, which is great, because I'm looking to start a makeup based YouTube channel, but when I film, I need to see what's on the camera. Is there anything I can attach to the camera to see what's going on in the view? I love how camcorders have the screen, that would be idea, but I don't want to have to buy one if I don't need to. Or can I hook my iPhone up to it, or?

Without knowing what camera you have, I'd have to say no.

Lots of people fail to buy cameras with:

* External Microphone Jack
* External HDMI output (for video)
* White balance correction

Now you know features to look for.

What camera is it?

If it has an HDMI connector on it, you can try connecting it to a monitor that accepts an HDMI input and see if it works.

You can also look in the manual.

It's cheaper to buy a low-end camcorder instead. Try Sony Handycam.
