A nightmare that shouldn't come true
An equipment failure with a camera, lens, memory card, hard drive, etc. is a nightmare and a worry for almost all photographers! If a photographer doesn't worry about that, then that is someone you probably don't want to work with.
It would be unfortunate, but a photographer that loses photos or has a camera malfunction during an event would prevent the photographer from satisfying the client. That is why every photographer that has those nightmares will take extreme effort to make sure this never ever happens.
If you're a client wanting to learn more about how I handle data, or you are a student learning photography, read on to learn about my three orders of prevention!
First order of prevention
Equipment should be inspected before the shoot to make sure everything is working properly and there is no damage. Settings should also be checked to make sure cameras are configured properly and not accidentally changed from the last photo shoot. If something bad still does happen, make sure to use extra or backup equipment, just in case!
Second order of prevention
Only the best memory cards should be used and only the fresh ones (not overused) should be put back into the camera. Large storage memory cards should also be used, so you will never have to take the cards out from the slots until you get back to your computer, which prevents any cards from becoming lost or damaged. Additionally, the cameras used should always have two memory card slots, so when an image is saved, it is automatically duplicated to a second memory card (just make sure you set your camera to the right setting).
Third order of prevention
Images are immediately transferred from the camera to a very secure computer, then backed up twice to multiple hard drives that are stored in secure locations. Don't delete the photos on the memory cards until the next shoot and have the photos permanently stored on RAID hard drives, and never deleted the unless it is absolutely necessary. Also, read my "Image Archive Backup" blog post to learn the steps to make sure your photos are kept safe.
A FEELING OF PEACE
Following these preventative measures should hopefully give you a feeling of comfort and safety. If you're considering hiring me as your photographer, rest assured that I handle your pictures very seriously.
IMPORTANT LIABILITY NOTE
When working with clients with these prevention steps, please keep in mind that sometimes it is inevitable that bad things can happen, but always make sure you do whatever you can to avoid such situations. And if it does, be prepared to do the best!
