When you are shooting for pay, always make sure that you carry:
- A spare camera battery.
- Spare batteries for your flash.
- Some Alkaline AAs.
- Spare memory cards.
- A spare flash.
- Spares for essential cables (e.g. to connect your flash to your camera or pocketwizards).
- Even, if at all possible, a spare camera.
That way you can offer your customer peace of mind, and you can rest assured that the price you charge is worth it – “Uncle Bob”, after all, does not carry the spares above.
I have been saved more than a few times by the spares above – yes, all of them.
