Here's some general photography tips to help you get better results.
1. Use a tripod or place camera on something steady
2. Shot in RAW so you can use a photo editor to tweak colors and white balance
3. Turn off all other lights to avoid reflections and mixing of light types
4. Manually set your white balance
5. Do not use flash
6. Switch to manual focus if AF is having trouble locking on due to the glass
7. If photographing something moving then either keep you shutter speed high or temporarily turn off flow
