Stop The Clothesline
The kit contains a gloriously orange USB cord that goes between your camera and your computer. There is a jerkstopper clip on either end to make sure that neither you nor any part of the connected gear part company unexpectedly in the dark.
To help you find the keys on the laptop keyboard in the dark, there is also a small LED lamp on a metal gooseneck that plugs in to a USB port. It works - I just plugged it into this laptop and I can see the keys as clear as day. Actually, it IS day, but let's not get fussy.
The real life saver is that orange cord. Studios are dark in the back and light in the front and strung with hazards. One day I will be found crushed under a light stand after pulling it over on myself with the black power cord that I could not see. It will be a fitting end - Elinchrom fitting, actually.
But if I have yellow power cords and this orange USB cable strung out in the dark I may be able to avoid the fate. You might wish to join me and live...I'll be back...
