I’ll be visiting a glass factory and want to make the most of a rare opportunity to photograph glassblowing and glowing molten glass. I’ll have a Canon EOS 550D with the 18-55mm f/3.5-5.6 kit lens.

What camera settings or approach should I use to capture the glow of hot glass without losing the atmosphere? I’m worried about underexposure because the workers move quickly and my lens isn’t very fast. Should I use flash, or will that ruin the natural look?

I’m also concerned about the extreme contrast between bright furnaces, glowing glass, dark interiors, and window light. How can I preserve as much detail as possible in a scene like this?

I would try to expose for the hot bright fire, and manually dial up your flash to fill in the rest. In other words - use your in camera meter in manual mode to get the correct exposure, then just flip up your flash. You can further adjust the flash settings to get the desired effect. Use a higher ISO to freeze the action with your setup - ISO 800 or 1200 would be a good place to start.

You are right in thinking that the flash could potentially destroy some of the mood, but used correctly as in the above suggested technique, you can make great images.

To maximize details - I would shoot sightly stopped down, that is, not at your maximum aperture of f/3.5 or f/4.0. Try f/5.6 or even a bit higher. Also, try to keep the main action at the center of the lens, and finally keep ISO as low as possible while still freezing the action.

Shoot RAW if possible, and bring a grey card for white-balance reference—the mixed, unusual lighting will confuse auto WB.

For exposure, prioritize the brightest areas: meter for the glowing glass/fire so highlights don’t blow out. Manual exposure or spot metering can help. Expect to raise ISO; ISO 800–1600 is a reasonable starting range on a 550D to keep shutter speeds high enough for worker movement.

Aperture depends on light and subject. In low light you may need to stay near wide open, but if you have enough light, stopping down a bit (around f/5.6) can improve sharpness. Keep important subjects near the center of the frame for best kit-lens performance.

Flash is optional. Direct flash can reduce the natural mood, but a little fill flash can work if you expose for the hot glass first and use flash only to lift darker areas. On cooler clear glass it may create small specular highlights; whether that looks good depends on the surface.

Also note that your 18–55mm may be limiting if you can’t get close—the example images may have used a longer focal length.
