Playing with fireworks, C&C please

[Eemilioc]

I made some trials in a dark room and I was wondering how can I maintain the sparks that I get in a high iso number (640) and also see the lines of fire that can only been seen in a low iso number (100), any C&C would be appreciated.
1. ISO 320 f29 30s

2. ISO 100 f32 30s

3. ISO 640 f29 30s

4. ISO 100 f29 30s

The time exposed was decided by the duration of the bengal lights (I think this is the right traduction)

these look really neat! I have played around doing the same type of thing using a flashlight before and it was quite fun. Are you suing sparklers?

I really don´t know the name in English ( luces de bengala en español ). They are wires with powder stuck to them that you light up

Nice, #3 is my favorite.

Here we call them sparklers.
What part of Honduras are you from? I was born in Tegucigalpa and lived there until I was 15 years old.

You won't be able to get both motion blur (low ISO, long shutter speed) and stopped-motion of individual sparks (High ISO, fast shutter speed) in the same photo.

I live in Tegucigalpa also, thanks for stating the right name, I also have a lot of trouble with specific terms used in the posts, but thanks again for your help.
