Using Portable Electronic Flash Units
If you need some extra, artificial light, the next take while traveling, portable electronic flashes are a great option to consider. Practically small, you should not worry about hampering it in terms of packaging if you are going to move a little or get away with all your equipment. This tool will only take a small part of your space travel, but it will open up a massive world of composition opportunities if used creatively.
Firstly, the peak intensity of the flash is incredibly short (in some units only 000 1/50 of a second), which means portable electronic flash units can be activated several times. This can totally freeze the action of a subject if you are able to position relatively close to blinking it.
Secondly, if you are working out, the color temperature of these units is remarkably similar to that of daylight, keep this in mind when considering the time of day you want to test the experimentation. You can manually control the intensity so that said light weak or stronger according to the corresponding aspect you are trying to achieve.
When it comes to keeping the device on and ready to go when traveling, these tools can be powered by rechargeable batteries (regardless of NiCd or NiMH) or AC. But remember, the charging process can take up to 24 hours so it is handy to fully charge the device a few days before the draw that will not succeed.
