learning to use the manual camera settings

[cellio]

When I've taken pictures of the chanukiyah in the past, I've usually been disappointed by how blurry the flames look. Photographing flames in a darkened room is apparently challenging -- it's not just me. I asked a question about it a while back on the Codidact photography community and got some interesting advice.

I've been experimenting this season. Here's one from tonight that came out decently well:

The camera settings were:

• Shutter speed: 1/90
• ISO: 1600
• Exposure: 0 (I don't know what this means; it's a scale from -2 to +2)

The other settings I have available are named:

• White balance: (scale of pictograms of sun, light bulbs, etc)
• Interval(s): scale from 0 to 60
• Focus: picture of flower, 25/50/75%, picture of mountain

I left those set to "auto".

I can make guesses (based on the scales) about white balance and focus, but "interval(s)" has me stumped.

It turns out that while I have a slider for "exposure", I can't activate it. Presumably its availability depends on something else that I haven't figured out yet. I'll need to look for documentation.

Thanks for explaining depth of focus, which I would have confused with focal distance otherwise. Different ideas -- one is the target, one is how precise that target is.
