ISO

In general when taking photos, my last resort for adjusting
exposure is the ISO. When I do use a higher ISO, say 400 or 800
does it impact the quality of the picture for posting?

ISO does impact the quality of the print, but the effect varies
by the camera. The photo becomes more and more grainy. If you
look at a high ISO photo, this page has some examples,

then you see the effect. Usually this is not the effect we want.
It does drastically increase as the ISO gets higher.
If additional light is not possible, a flash or turning on more
light, a higher ISO is usually your only option.
I will have to write more later.

Sorry, I had to run.
I was going to say that I have had cameras where I can't go
about 400 with out a HUGe difference. That is when I used my
flash a lot. Probably your best option for now.
Another option, IN SOME CASES, is a slow shutter speed. To avoid
blur with a low shutter speed you can always put your camera
down on a flat unmoving surface, though there will be some
movement simply by the function of the camera, but that is
usually nit picky. I learned how to butt up against a wall, hold
my breath, and take the shot 10 or 15 times. I usually got lucky
with one. Of course this is all with an unmoving subject, like a
room shot. With people, ask them to move into a better lit
space, "This lighting is so flattering. Can you step over hear a
little more?"
Also a bouncer on your flash makes a huge difference. I never
shoot with a direct flash. Many flashes have them built in. If
not, they are around $10-$50 for an ok to good one. Also in a
pinch you can make one with some tracing paper or construct a
bouncer with an index card.
These are to show what I was talking about. I do not suggest
buying this particular item at this website, these are to give
you information and then I would comparison shop for similar
items if you want them. Photography is an expensive hobby. Be
smart about what you buy.
Similar bouncer to what I have used in the past.
